How much has the brain diminished in size over the last 20,000 years?

Due to the use of symbolism, greater efficiency reduced the need for energy-hungry brain tissue
Why did people benefit from having smaller brains?

Participants had to order pictures that they liked from most to least, then came back a week later and did the same
Despite not remembering coming the week before, participants with AD orders the pics more or less the same

- disposition to produce visual art
- provision of a unique visual vocab
- aids to descriptive accuracy
- changes in expressive powers
Neurological disorders related to obsessive - compulsive disorders can do what?
Increase art production
When can you develop compulsions?
When the frontal lobe gets damaged
Neurological disorders related to migraines are linked to what?
