Pro Tip 1/3Human Anatomy
Used in biology and medicine to discuss human or animal bodies.
Studying the structure of the brain's cortex can help doctors understand neurological diseases.
Pro Tip 2/3Technical Term
Highly specific and used in scientific or medical contexts.
The cortical neurons in the cerebral cortex are essential for cognitive functions.
Pro Tip 3/3Not Interchangeable
'Cortex' describes the outer layer, not to be confused with the core or inner parts.
Damage to the cortex can impair sensory perception.

I learned in the computer game business early on that all senses are not equal. The best example is, you're listening to a radio play and you're driving down the road, and suddenly you realize you haven't seen the road in five minutes. It's because your visual cortex has been partying with your imagination, basically.
Quote examples
Daniel Levitin
American Scientist
There's an ancient connection between movement and music. Most languages don't make a distinction between the words 'music' and 'dance.' And we can see that in the brain. When people are lying perfectly still but listening to music, the neurons in the motor cortex are firing.

When I sit down to make music, I try to enter a flow; I always open a blank session and just make something that I feel like making. Only after a piece of music is done does my frontal cortex allow me to organize what might be trying to come out of my subconscious.
Quote examples
Sherwin B. Nuland
American Scientist
Where the despair of loneliness and poverty haunts every hour, the optimism to embark on new projects cannot find a place to alight on the brain's cortex. Poverty itself is an enormous obstacle to an enlightened and enlightening - not to say healthy - old age.

Stephen LaBerge
American Psychologist
Your experience is a dream; so is my experience. This stuff about how the frontal cortex is repressed during dreaming, lucid dreaming presents an obvious contradiction to it. The only difference is sensory input.

Deep in my cortex, the year is divided into reading seasons. The period from mid-October to Christmas, for instance, is 'ghost story' time, while Jane Austen and P. G. Wodehouse pretty much own April and May.

The moment you feel yourself hesitate on something you know you should do, count 5-4-3-2-1 to activate your prefrontal cortex and interrupt the habit of overthinking, self-doubt, and fear.

What adolescence is about is by trial and error, honing a frontal cortex that is going to be more optimal by the time you're 25.

The limbic system explodes during puberty, but the prefrontal cortex keeps maturing for another 10 years.
