1
00:00:00,040 --> 00:00:02,720
Wow, that is not just mind 
blowing, that's brain blowing. 

2
00:00:03,200 --> 00:00:06,560
Like that's NSR team and yeah, I
am going to go into the 

3
00:00:06,560 --> 00:00:11,080
prefrontal cortex. 
Our questions, shout out to Maya

4
00:00:11,080 --> 00:00:15,920
E Congo from Abu Dhabi. 
So number one is does the 

5
00:00:16,200 --> 00:00:21,480
prefrontal cortex develop 
differently depending on gender?

6
00:00:23,640 --> 00:00:25,880
Oh man, that's a good question. 
You know, honestly, I can't say 

7
00:00:25,880 --> 00:00:29,280
for sure. 
I remember seeing some studies 

8
00:00:29,280 --> 00:00:31,840
on this like a couple of years 
ago, and I don't think I ever 

9
00:00:32,479 --> 00:00:35,560
really got to the bottom of it. 
I'm sorry, I can't give a 

10
00:00:35,560 --> 00:00:38,360
definitive answer, but you know,
hey, this is also one of those 

11
00:00:38,360 --> 00:00:42,360
things where you don't want to 
look stupid asking questions. 

12
00:00:43,360 --> 00:00:45,560
What kind of neuroscientist 
wants to come on a podcast and 

13
00:00:45,560 --> 00:00:49,040
say, I don't know the answer? 
The answer is an honest one, one

14
00:00:49,040 --> 00:00:51,520
that will actually say, look, I 
don't you know, this is the you 

15
00:00:51,520 --> 00:00:53,320
have reached the limits of my 
knowledge. 

16
00:00:53,640 --> 00:00:56,600
And I think that's also, by the 
way, a good sign of who you 

17
00:00:56,600 --> 00:00:58,240
should trust. 
If you ask someone a question 

18
00:00:58,240 --> 00:01:00,880
and they always have the. 
Absolutely, absolutely. 

19
00:01:00,880 --> 00:01:03,280
I always say something, you 
know, I'm a professional, right?

20
00:01:04,400 --> 00:01:08,200
But I don't know all the answers
but I've had myself. 

21
00:01:08,200 --> 00:01:10,160
That's OK. 
Knowing we had to get the 

22
00:01:10,160 --> 00:01:12,680
answers if I need to. 
Exactly, exactly. 

23
00:01:12,680 --> 00:01:15,640
Yeah, I could find that answer. 
Maybe I'll check it out and I'll

24
00:01:15,680 --> 00:01:16,440
send. 
It and of course. 

25
00:01:17,000 --> 00:01:22,160
So that means that automatically
we should book a party for this.

26
00:01:23,320 --> 00:01:24,480
So now you're going to come 
back. 

27
00:01:24,760 --> 00:01:26,560
You can come back with a Cortex 
edition. 

28
00:01:28,080 --> 00:01:29,960
Yeah. 
Prefrontal cortex addition. 

29
00:01:30,280 --> 00:01:35,480
You said you're ready. 
So #2 is a Does a stress or 

30
00:01:35,480 --> 00:01:40,400
trauma inhibit its function, 
particularly before it's fully 

31
00:01:40,400 --> 00:01:42,760
developed? 
Interesting. 

32
00:01:43,320 --> 00:01:45,240
Yes, so I do know the answer to 
this one. 

33
00:01:46,520 --> 00:01:49,800
Stress does influence the 
function of the prefrontal 

34
00:01:49,800 --> 00:01:52,000
cortex. 
It's quite interesting also 

35
00:01:52,000 --> 00:01:54,880
based on some research done in 
my PhD lab. 

36
00:01:55,280 --> 00:02:00,400
So when in in short term stress,
couple days, couple hours, 

37
00:02:00,400 --> 00:02:03,520
whatever the the prefrontal 
cortex actually gets more 

38
00:02:03,520 --> 00:02:06,320
effective, it becomes better, 
like the cells are are 

39
00:02:06,320 --> 00:02:08,720
interacting more efficiently. 
Which makes sense because you 

40
00:02:08,720 --> 00:02:09,800
have to deal with some 
challenge. 

41
00:02:09,800 --> 00:02:12,400
You need to be locked in, right?
You got to be capable of 

42
00:02:12,400 --> 00:02:15,960
processing the challenge. 
But with chronic stress over 

43
00:02:15,960 --> 00:02:19,360
time goes for weeks or months, 
the prefrontal cortex, the 

44
00:02:19,360 --> 00:02:22,320
function goes way down and the 
brain cells actually become less

45
00:02:22,320 --> 00:02:24,880
effective at interacting. 
What what's really happening 

46
00:02:24,880 --> 00:02:29,600
amazingly, is that the, the 
receptors on the neurons where 

47
00:02:29,600 --> 00:02:31,600
you know, brain cells are 
sending messages to each other, 

48
00:02:31,920 --> 00:02:35,880
the receptors start going away. 
And so the brain cells actually 

49
00:02:35,880 --> 00:02:39,080
have trouble communicating with 
each other. 

50
00:02:39,080 --> 00:02:40,720
And, and basically what that 
amounts to is that you're 

51
00:02:40,720 --> 00:02:44,040
processing power and your 
computing power goes down South.

52
00:02:44,040 --> 00:02:48,400
Chronic stress is bad. 
As for the timing, I don't think

53
00:02:48,400 --> 00:02:54,360
it can, you know, impair I, you 
know, I would say in the context

54
00:02:54,360 --> 00:02:59,920
of like normal ranges of stress 
will not necessarily change the 

55
00:02:59,920 --> 00:03:02,880
function of your prefrontal 
cortex long term, but like 

56
00:03:02,880 --> 00:03:06,040
traumatic stress, like PTSD, you
know, really traumatic 

57
00:03:06,040 --> 00:03:07,560
experiences. 
It could I've been. 

58
00:03:07,560 --> 00:03:09,760
I believe there is evidence that
that it does alter the the 

59
00:03:09,760 --> 00:03:11,280
function of the prefrontal 
cortex. 

60
00:03:12,440 --> 00:03:16,400
Interesting. 
SO there's a third question, and

61
00:03:16,400 --> 00:03:21,000
that is how is the prefrontal 
cortex different from other 

62
00:03:21,000 --> 00:03:25,400
parts of the frontal lobe? 
I mean, the prefrontal cortex is

63
00:03:26,480 --> 00:03:29,160
the most like evolved. 
It's like the, it's the, it's 

64
00:03:29,160 --> 00:03:31,880
the reason you have the frontal 
cortex and then you have the 

65
00:03:31,960 --> 00:03:34,200
prefrontal cortex. 
The prefrontal cortex is even 

66
00:03:34,440 --> 00:03:37,760
more for towards the front. 
And there's this general idea 

67
00:03:37,760 --> 00:03:41,720
that like the further away from 
the brain stem you get and like 

68
00:03:41,720 --> 00:03:46,080
this base level, the more 
evolved and, and fancy the brain

69
00:03:46,080 --> 00:03:48,240
area is. 
And so the prefrontal cortex, it

70
00:03:48,960 --> 00:03:51,000
just, it has a lot of amazing 
functions that aren't 

71
00:03:51,000 --> 00:03:53,560
necessarily seen in the, the 
frontal cortex, like much more 

72
00:03:53,560 --> 00:03:56,760
higher level of cognition and 
being able to understand people 

73
00:03:56,760 --> 00:03:58,520
and do things that make us human
really. 

74
00:03:59,200 --> 00:04:03,040
But, but The thing is the, the 
prefrontal cortex is also like 

75
00:04:03,040 --> 00:04:05,520
every brain area. 
It's like very distributed. 

76
00:04:05,520 --> 00:04:07,960
There's all these different 
nuclei and brain and sections, 

77
00:04:07,960 --> 00:04:11,080
you know, within the prefrontal 
cortex there's the dorsolateral 

78
00:04:11,080 --> 00:04:14,680
prefrontal cortex and all these 
different subsets of areas that 

79
00:04:14,680 --> 00:04:16,320
are all involved in different 
things. 

80
00:04:16,600 --> 00:04:19,760
And you know, the brain is just 
immensely complicated. 

81
00:04:20,160 --> 00:04:23,000
But without a prefrontal cortex,
you know we would not be as high

82
00:04:23,000 --> 00:04:24,720
functioning animals. 
I like that. 

83
00:04:25,200 --> 00:04:30,080
I always say that human beings, 
we are animals, it's just that 

84
00:04:30,080 --> 00:04:32,600
we are higher animals, right? 
And of course, we have the 

85
00:04:32,600 --> 00:04:34,400
animals with the highest level 
of IQ. 

86
00:04:34,440 --> 00:04:36,080
That is why we are able to 
dominate. 

87
00:04:36,080 --> 00:04:42,440
So #4 is the prefrontal cortex 
is sometimes called the CEO of 

88
00:04:42,440 --> 00:04:45,480
the brain. 
Why is that and do you agree 

89
00:04:45,520 --> 00:04:50,480
with that? 
Interesting You could say that 

90
00:04:50,640 --> 00:04:52,800
you, I guess, I mean, there's a 
couple different CE OS of the 

91
00:04:52,800 --> 00:04:55,280
brain and actually the nucleus 
accumbens that I mentioned 

92
00:04:55,280 --> 00:04:58,080
earlier in the context of MDMA 
is also one of those. 

93
00:04:58,080 --> 00:05:00,680
But I would say, yeah, I guess 
the way I kind of think about 

94
00:05:00,680 --> 00:05:03,080
the prefrontal cortex is it's 
like the babysitter of the 

95
00:05:03,080 --> 00:05:04,480
brain. 
You have all these brain areas 

96
00:05:04,480 --> 00:05:06,200
that are just like impulsive and
they're doing their job. 

97
00:05:06,200 --> 00:05:09,920
And your prefrontal cortex is, 
is often like shutting off those

98
00:05:09,920 --> 00:05:11,600
impulses and being like, wait, a
wait. 

99
00:05:11,760 --> 00:05:15,080
But you know, before we slap 
this person in the face, let's 

100
00:05:15,080 --> 00:05:17,680
think about this for a minute, 
you know, and it's kind of 

101
00:05:17,680 --> 00:05:20,320
babysitting and keeping those 
brain areas in check. 

102
00:05:20,320 --> 00:05:22,480
So yeah. 
And many, many, it is the CEO. 

103
00:05:22,480 --> 00:05:26,040
But I like to think of the the 
CEO of the brain sort of as the 

104
00:05:26,040 --> 00:05:28,680
nucleus accumbens, because the 
nucleus accumbens is really in 

105
00:05:28,680 --> 00:05:30,800
charge of like decision making 
or not in charge of it. 

106
00:05:30,800 --> 00:05:35,080
But it has a major role in like 
deciding what things we pursue 

107
00:05:35,080 --> 00:05:38,440
and what actions we do based on 
how much they benefit us. 

108
00:05:38,440 --> 00:05:40,680
And you know, I think that's 
kind of like the role of the CEO

109
00:05:40,680 --> 00:05:43,480
really. 
So is it the CEO or the COO? 

110
00:05:44,440 --> 00:05:48,280
I feel like the, the, the, the 
nucleus accumbens is the CEO and

111
00:05:48,280 --> 00:05:50,840
the prefrontal cortex is like 
the executive board like that, 

112
00:05:50,840 --> 00:05:53,080
you know, you have a board of 
direct or a board that's like 

113
00:05:53,440 --> 00:05:55,320
steering the company in the 
right direction. 

114
00:05:55,880 --> 00:05:59,240
I feel like that's sort of those
two are combining to to make 

115
00:05:59,240 --> 00:06:03,520
things work properly. 
OK, interested stuff. 

116
00:06:03,680 --> 00:06:07,880
So this particular friend of 
mine, Maya, she, she's very 

117
00:06:07,880 --> 00:06:09,800
obsessed with the prefrontal 
cortex. 

118
00:06:10,160 --> 00:06:15,880
And anytime she sees a person 
acting, you know, in an abnormal

119
00:06:15,880 --> 00:06:18,840
way, she just says, oh, that 
person's prefrontal cortex is 

120
00:06:18,840 --> 00:06:23,280
not properly developed. 
And she's told me before that 

121
00:06:23,360 --> 00:06:28,280
the prefrontal cortex actually 
fully develops at the age of 25.

122
00:06:29,320 --> 00:06:32,560
Is is is that true? 
Yeah, the prefrontal cortex, 

123
00:06:32,680 --> 00:06:37,440
whether it's there's definitely 
not like a you, you're 25, it's 

124
00:06:37,440 --> 00:06:38,960
done. 
It's not really like that. 

125
00:06:39,120 --> 00:06:42,640
It's more of that, you know, as 
you're getting older, your 

126
00:06:42,640 --> 00:06:45,160
prefrontal cortex is continuing 
to be shaped by your 

127
00:06:45,160 --> 00:06:48,760
experiences. 
That's really what that whole 

128
00:06:48,760 --> 00:06:52,120
like your prefrontal cortex 
isn't done until 25 means. 

129
00:06:52,120 --> 00:06:56,800
It means that unlike other brain
areas, your Pfc remains flexible

130
00:06:57,240 --> 00:07:00,640
as you get older. 
And so, you know, it may not, it

131
00:07:00,640 --> 00:07:05,400
may be 25 that you kind of get 
to that point or maybe a little 

132
00:07:05,400 --> 00:07:08,280
bit later. 
You know, it doesn't really, 

133
00:07:08,320 --> 00:07:11,280
it's not like a firm thing that 
it's like boom, 25, you're done.
