Hello, I'm Dr Hannah Critchlow.
5
I'm a fellow here at Magdalen College, Cambridge University.
6
I've been researching the 21st century brain and how we can all future -proof our minds in the age of AI.
7
I would say no, because embedded within our brains is this incredible mechanism called synaptic plasticity.
8
If we skip back in our species history, then similarly in the 21st century BC, humanity was undergoing a big evolutionary shift.
9
There was the widespread use of the written word.
10
We were also using metals to develop incredible tools, including weapons.
11
and we were starting to live in more city -like states.
12
If we now skip forward to today, the 21st century AD, We similarly seem to have been compelled to develop incredible technologies
13
that allow us to communicate with one another across the globe as never before.
14
The invention of the internet, social media, even the development of artificial intelligent technologies
15
that have been very much inspired on understanding of how our own neural networks operate to create human intelligence.
16
We've developed these technologies that allow us to share our perspectives, share our knowledge, across generations and across the world.
17
And I would say that our ability
18
To have this synaptic plasticity within our brain that allows us to learn from our environment, to remember new things and behave in new ways so
19
that we can innovate and problem solve
20
and evolve into the future will again help us to thrive into the 21st century and beyond.
21
Now traditionally, societies and scientists really thought that our species' success was underpinned by our ability to be logical,
22
to reason and to be rational.
23
And actually our emotions were this sloppy hysterical thing that really we should try to control or quash or ignore.
24
Increasingly, scientists and society are starting to appreciate how our emotions actually bring with them lots of layers of additional information.
25
And they can be used as guides to help us with our decision making.
26
So we know, for example, now, that our emotional intelligence is the number one predictor for our life success and satisfaction levels.
27
And scientists have increasingly been able to study this incredibly complex behaviour of emotional intelligence and empathy,
28
and we now have tools to start to measure it more precisely.
29
And what we're finding from the scientific studies is that emotional intelligence is not very heritable.
30
So it's got a heritability level of around 10 to 45%, meaning
31
that the genes that we've been given from our mum and dad actually don't play a big component in this complex behaviour.
32
Now this means that our environment, the society we're in, plays a big major role in shaping our emotional intelligence.
33
And this also brings with it good news because it means that we can all enhance or elevate our emotional intelligence,
34
regardless of the genes that we've been given from our mum and from our dad.
35
So, how do we do this?
36
Well, simple things like, for example, looking each other in the eye directly.
37
We can also practice self -compassion, so spend time listening to our own emotions and actually trying to use them to help us to guide our behaviour.
38
We can also spend time reading fiction books, which place us in other people's worlds, help us to learn about other people's perspectives and the journeys that they go on.
39
And in fact, there's medical schools in America that have introduced humanity classes
40
that are essential for their students to help develop their emotional intelligence and empathy skills.
41
We can even feed our emotional intelligence.
42
There was a lovely study that was published recently where they took a hundred volunteers and half of them,
43
they actually fed them with prebiotics and probiotics just for a small number of weeks
44
and that helped to enhance their altruistic behaviour.
45
So they were much more likely to act with other people in mind, creating a much more egalitarian state.
46
-Hum.
47
Now, leaders have to make sometimes very difficult decisions, and it helps them not to be too swayed by everybody else's situation.
48
And unfortunately, As we've all seen, this can sometimes go too far in the wrong direction.
49
Now, embedded within our nervous system are these very clever mechanisms that help leaders to make these difficult decisions.
50
So for example, if you're in a position of power, your mirror neuron circuits, which are nerve cells within the brain,
51
that are thought to be involved in our ability to imitate one another and to have empathy for others.
52
These nerve cells actually start to quieten down with electrical activity when people are in a position of power.
53
Now there's a lot of information from the outside world
54
and from the people around us that we don't actually store within our brains.
55
We store that knowledge within our peripheral nervous system and particularly from the nerve cells in the gut and in the heart.
56
I don't know whether you've ever had a gut feeling about something or a heart flicker.
57
That's those nerve cells that live there sending a little signal up via the vagus nerve,
58
which is a cable or a bundle of nerve cells that runs all the way from those organs up to the brain, and to a particular region called the insula,
59
which is involved in monitoring the information from your body and also the knowledge and the people and the environment around you.
60
And when you're in a position of power, there's a dampening down of that vagal nerve sensitivity,
61
which means that you're less able to take on board that knowledge from the outside world, and use it in your decision making.
62
Now, is there anything that we can do to help combat this impact of power on the nervous system?
63
So that we can immunize its negative effects, if you like?
64
Well, yes, thankfully there does seem to be.
65
So, for example, if we just spend 30 seconds every day doing some exercises to get our heart rate up,
66
Then spend the next 30 seconds listening to that strong heart beat and really tuning into it.
67
And if we do this for just a small number of weeks,
68
it can help us to get into the habit of listening to our peripheral nervous system and listening to that collective knowledge,
69
that wisdom from the outside world, that's being stored in that embodied cognition.
70
Thank you.
71
We might be finding it increasingly difficult to think with clarity and precision.
72
There is no doubt lots going on in our environment in the current day.
73
However, there are some key ways that we can help our brain to focus and think clearly and not get overwhelmed.
74
So for example, making sure that we eat healthily so our brain is getting the nutrients that it needs, and so that we're not filling our diets with processed food
75
that actually lack that nutritional value that our bodies and brains are sometimes screaming for.
76
Also making sure that we sleep so
77
that we can help to consolidate what we've learned from the day before into nice stable memories
78
so that we can form new habits in behaviour.
79
And so we know that if we exercise regularly, then that helps to create new nerve cells within the brain,
80
particularly the hippocampus, which is a key region of the brain involved in learning
81
and memory and helping us to navigate our environment.
82
So that advice all seems very intuitive.
83
It's things that we all really know already to be true.
84
But more recently, there's some new neuroscience knowledge that's coming out that can similarly help us to make the right decisions.
85
21st century brain, I went to James Cook University to meet with Professor Zoltan Skorny.
86
He's leading one of the world's largest randomised controlled trials, looking at how our diet can influence our ability to think clearly and with precision.
87
He's looking at one extreme end of the spectrum for this behaviour.
88
And I met with some of the patients that are on the trial.
89
They've been diagnosed with schizophrenia or bipolar.
90
So conditions that are very much characterised by very chaotic
91
disorganized thought that might result in hallucinations or delusions and a difficulty creating reality.
92
And he's found that simply changing their diet can have a profound impact on their ability to think clearly and with precision.
93
effectively removing their debilitating symptoms.
94
It's incredibly important for groups of brains or groups of people to work together well.
95
And scientists have started to recently study exactly how that magic can happen in the brain.
96
If we hook up individuals to an EEG machine so that we're measuring the electrical activity within their brains, we can see
97
that the degree of brain synchronicity between the individuals in the team can actually be used to predict how well
98
that group of people works are working together.
99
if they're learning from each other.
100
if they're building consensus, if they're having dissent but without conflict.
101
if they're allowing ideas to hop from mind to mind so that they can innovate and problem -solve effectively, then you can see this within the brain.
102
The degree of brain synchronicity,
103
so those electrical traces lining up with each other between brains can predict how well a group of people are working together.
104
So knowing this, is there anything that we can do to help boost a team's performance fire their brain synchronicity.
105
Yes, So it's simple things that again we know intuitively to be true.
106
So if we look each other in the eye directly, That helps to boost brain synchronicity.
107
If we do simple things like sing with each other.
108
And that helps to increase brain synchronicity.
109
And if we look throughout our species history, embedded across many different religions across the globe, we see rituals of chanting,
110
of singing together and praying together.
111
Skills that help to boost that brain synchronicity, helping us to bond.
112
We also know that exercising together helps increase brain synchronicity, and as does being in a positive mood.
113
And in fact, we can even predict within 30 seconds of a group of strangers coming together, who's going to be the leader of the group,
114
by looking at the degree of brain synchronicity they exhibit.
115
So those that fall in line with others and sometimes lead
116
that dance of brain synchronicity are much more likely to be the leaders of the group.
117
Now our brains, as clever as they are, they basically operate as prediction machines.
118
So they like to
119
process information from the outside world and then predict what's going on and then create an output which is our behaviour.
120
Now, to put this in numbers, something like 11 million bits of data enters our senses every single second.
121
It's a vast amount of information, but we're only consciously aware of something in the region of 40 bits per second.
122
So a huge amount of information we discard, we don't prioritise and we're not consciously aware of.
123
And our brains have to do this so that we can actually keep up with reality.
124
Otherwise we might effectively just blow a fuse.
125
So in order for our brains to do this we basically create shortcuts in our thinking.
126
We use our past to create a lens of expectation for how we want to interact and navigate through the world.
127
This creates biases or assumptions within our brain.
128
It creates shortcuts in our information processing, so that we can function effectively.
129
When you're dealing with a new situation, when there's a lot of uncertainty and ambiguity in your environment, your brain struggles to predict.
130
It doesn't really know what's going on and it has to analyse lots of new data at the same time.
131
And if there's a lot of ambiguity or uncertainty in our environment,
132
our brain has to work incredibly hard to do all the metabolic work in order to have the agility
133
and the nimbleness to think our way through this new situation.
134
The one thing that we do know for sure though, is that none of us predict our futures.
135
We have uncertainty all the time in our environment.
136
We don't know what tomorrow will bring, let alone the next month or the next year.
137
So how do we increase our tolerance for it?
138
Well, making sure that our nervous system isn't feeling too stressed. or fearful.
139
So for example, simple things like breathing.
140
Breathing in for four seconds.
141
Thank you and then exhaling for four seconds.
142
and tracing the shape of a box.
143
with each breath.
144
and doing a few iterations of that can help calm the nervous system.
145
We know that a small amount of stress is actually quite good for our brains.
146
It increases the flexibility or the plasticity in the brain.
147
but chronic amounts of stress feeling fear, feeling very much frightened of our environment.
148
can actually cause neurotoxicity.
149
IT'S A LITTLE BIT OF A strips connections in the brain, And it can also, in severe cases, cause nerve cells to die.
150
It can also decrease the rate of neurogenesis.
151
so that not as many new nerve cells are being born in the brain to help us to learn
152
and remember in new ways.
153
So it's really important for us to approach uncertainty and ambiguity, with feelings of possibility rather than fear or doom.
154
And see, opportunity within these situations rather than simply being frightened.
155
So we seem to have been compelled to develop these incredible technologies going back to the 21st century BC
156
when the written word was coming into widespread use.
157
to nowadays where we have increasing numbers of technologies that allow us to share our perspective,
158
to allow us to share our information and our knowledge about the world with others.
159
The internet, the development of social media, the development of artificial intelligence systems that allow us to trawl through vast data sets
160
and see patterns to change our perspective of the world and how we understand it.
161
All of these technologies have arisen from the human mind.
162
And all of them, I would argue, help us to connect.
163
on a deeper level.
164
This ability of ours, this drive of ours to connect with one another, seems to have underpinned our species' success in the past.
165
but also in the future.
166
And many researchers believe
167
that we're undergoing a massive evolutionary transition towards creating a hyper -connected organic computer if you like or a human hive mind,
168
allowing us to share our ideas and to innovate and to share our perspective and knowledge like never before.
169
And I think amongst all of this technological developments, we have to really value our ability to connect with others on a human level.
170
Two of the communities that I've been very much lucky to be involved in is the houseboat community on the River Cam,
171
and also the college community here at Magdalen at Cambridge University.
172
And there, there is a real sense of human connection, of valuing each other's intelligence of being challenged by different perspectives.
173
and actually helping to move are thinking forwards as a result.

| संरचना | वीडियो में |
|---|---|
| Present perfect have/has + past participle — बीता हुआ काम जिसका असर अभी भी है | have been · We've developed · we've been given |
| Passive voice be + past participle — ज़ोर इस पर कि क्या होता है, न कि कौन करता है | have been compelled · was underpinned · we've been given |
| Relative clauses who / which + उपवाक्य — व्यक्ति या वस्तु के बारे में अतिरिक्त जानकारी | circuits, which are · hippocampus, which is · output which is |
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
