The Voltage Trap. Why Frankenstein's Creature Would Never Wake Up.

00:00:07.530 --> 00:00:10.929
A heavy switch slams forward. Spark gaps erupt with blinding
3
00:00:10.970 --> 00:00:13.660
blue light. The massive surgical table descends from the open
4
00:00:13.699 --> 00:00:19.719
skylight and Frankenstein famously bellows, It's alive! Mary Shelley published
5
00:00:19.739 --> 00:00:23.440
Frankenstein almost 108 years ago in 1818, inspired by the
6
00:00:23.500 --> 00:00:28.289
Galvano electric experiments of Luigi Galvani and Giovanni Aldini, who
7
00:00:28.320 --> 00:00:32.310
made severed frog legs and executed convicts twitch using electrical currents.
8
00:00:33.229 --> 00:00:37.929
In cinema, reanimation looked simple. Connect the anatomy, introduce high-voltage electricity,
9
00:00:37.969 --> 00:00:43.170
and restart the pulse. And consciousness returns. In clinical neuroscience,
10
00:00:43.189 --> 00:00:46.909
that leap collapses. Let's start with the heart versus the brain.
11
00:00:47.030 --> 00:00:52.000
Cardiac muscle tissue is myogenic. Pacemaker cells in the cyanoatrial
12
00:00:52.060 --> 00:00:57.030
node generate their own rhythmic depolarizations, and electrical... Cardioversion can
13
00:00:57.570 --> 00:01:02.439
reset an uncoordinated rhythm, like ventricular fibrillation. If an intact
14
00:01:02.479 --> 00:01:06.019
heart has maintained a basic metabolic substrate, an electrical pulse
15
00:01:06.040 --> 00:01:12.010
can restore mechanical circulation. Restoring a pulse, though, is a
16
00:01:12.069 --> 00:01:15.629
world away from restoring a mind. The human brain comprises
17
00:01:15.629 --> 00:01:20.310
86 billion neurons interconnected by over 100 trillion synapses. It
18
00:01:20.349 --> 00:01:23.969
consumes 20% of the body's resting oxygen and glucose, despite
19
00:01:23.989 --> 00:01:28.989
accounting for only 2% of total mass. And that's quite
20
00:01:29.010 --> 00:01:33.750
a bit. But as we move along, you also have
21
00:01:33.790 --> 00:01:41.400
other issues. Deprived cortical tissue of oxygenated blood for just
22
00:01:41.420 --> 00:01:45.680
4-6 minutes at normal thermic temperatures and there's irreversible damage.
23
00:01:49.579 --> 00:01:53.469
These chemical reactions that start taking effect, they can destroy
24
00:01:54.730 --> 00:01:58.530
all sorts of things in the brain. By the time
25
00:01:58.609 --> 00:02:02.870
Victor stitched together donor tissue from execution grounds and charnel houses,
26
00:02:04.109 --> 00:02:09.939
anostasis had already dismantled the delicate molecular architecture of the
27
00:02:09.979 --> 00:02:12.900
synapses in the brain. A dead brain is not an
28
00:02:13.020 --> 00:02:17.199
unplugged computer waiting to be plugged back in. It is
29
00:02:17.240 --> 00:02:20.689
a motherboard whose circuits have chemically melted. Even if we
30
00:02:20.750 --> 00:02:25.250
suspend disbelief and imagine pristine tissue preservation, how does one
31
00:02:25.289 --> 00:02:29.800
establish functional neural connectivity across severed tissue? You cannot simply
32
00:02:29.919 --> 00:02:36.680
suture the brainstem to the spinal cord. Axonal regeneration is
33
00:02:36.699 --> 00:02:39.960
the central nervous system is actively blocked by glial scars
34
00:02:40.699 --> 00:02:46.129
and myelin-associated inhibitory proteins. What about the spark itself? In
35
00:02:46.150 --> 00:02:49.289
the living brain, neural signaling is not raw, undirected amperage.
36
00:02:49.310 --> 00:02:55.780
It is a microvolt-level electrochemistry modulated across nanometer-wide synaptic clefts.
37
00:02:56.840 --> 00:03:00.240
A lightning strike might trigger erratic muscular contractions through residual
38
00:03:00.280 --> 00:03:05.120
motor nerves, but coordinated cognition? Well, you'd have to suspend
39
00:03:05.159 --> 00:03:11.379
belief to an incredible degree. So Victor Frankenstein didn't generate
40
00:03:11.419 --> 00:03:14.509
a sentient mind at all. At best, he created an
41
00:03:14.569 --> 00:03:20.759
electrically charred biological battery. That's it. So Frankenstein, he would
42
00:03:20.780 --> 00:03:21.680
have never woken up.
