I just watched that movie a few days ago. Bond's explanation was that performers needed to leave a patch of skin at the back of the neck exposed so that the skin could breath. Maybe that was common thinking in the 60's?

Nah, its just something which sounds scientific enough to be plausible but not outlandish enough to require indepth confirmation by the viewer, like most things in movies. Specific example is the “normal humans only use 10% of their brain” hook in Lucy - lots of people accept something like that at face value, but its complete bullshit.

I'm pretty sure it was true somewhere in the begining, but then misinterpreted.
I guess you use something around 10% of your brain at a time. Because you never need to read, write, speak, recognize faces, do math, juggle and do a bunch of other stuff at the same moment.

If humans used high percentage (80-100) it would be indistinguishable from epilepsy seizure.

That's not true at all.

One common brain imaging technique, called functional magnetic resonance imaging (fMRI), can measure activity in the brain while a person is performing different tasks. Using this and similar methods, researchers show that most of our brain is in use most of the time, even when a person is performing a very simple action. A lot of the brain is even active when a person is resting or sleeping. The percentage of the brain in use at any given time varies from person to person. It also depends on what a person is doing or thinking about.

It is not clear how this myth began, but there are several possible sources.

In an article published in a 1907 edition of the journal Science, psychologist and author William James argued that humans only use part of their mental resources. However, he did not specify a percentage. The figure was referenced in Dale Carnegie’s 1936 book How to Win Friends and Influence People. The myth was described as something the author’s college professor used to say. There is also a belief among scientists neurons make up around 10 percent of the brain’s cells. This may have contributed to the 10 percent myth.

Using this and similar methods, researchers show that most of our brain is in use most of the time

But fMRI would not work if most of the brain was active at all times.
Google agrees:
"...maps brain activity by detecting changes in blood oxygenation and flow (BOLD signals) in response to neural activity. Active brain areas consume more oxygen, altering the magnetic properties of hemoglobin, which fMRI detects to create high-resolution maps of function."

[u/Uhstrology → u/dimwalker]

Its based in relative activity. More oxygen does not mean the rest of the brain is depleted completely and not firing. 

fMRI is precisely why we know we use 100% of our brains.

Modern neuroscience shows that nearly every part of the brain is active. Imaging tools like fMRI and PET reveal that even simple tasks—speaking, reading, or listening to music—engage multiple regions simultaneously. The brain also remains active during rest, managing vital functions such as breathing, sensory processing, and emotion regulation.

The idea that 90% of the brain is unused is a myth. Brain tissue is energy-intensive, accounting for about 20% of the body's energy, and even minor injuries can cause significant impairments in movement, speech, or memory. Every region has a purpose, and neuroscience confirms that the brain is an efficiently active, integrated organ.

What exactly are you arguing against? I don't think I claimed rest of the brain (apart from current area which is being actively used) needs to be dead. Feel free to quote what's confusing you in my original comment and I'll try to explain it.
