Brain

Question 1

Characteristics of a brain with ADHD

Answer 1

3-4% smaller, poorer filtering of info; overload of cortex. Cerebral Cortex metabolizes less glucose and is therefore it is less active and thinner

Question 2

Characteristics of a brain without ADHD

Answer 2

larger, better filtering; no cortex overload. Cerebral cortex metabolizes more glucose and is therefore more active and thicker

Question 3

Brain stem

Answer 3

Reticular formation (inside medulla oblongata) is responsible for filtering sensory input and analyzing this info; essential to consciousness, awareness, and sleep

Question 4

Caudate Nuclei

Answer 4

1 deep inside each hemisphere responsible for coordination movement

Responsible for voluntary muscle movement, speech, association (analysis integration) of thought

Question 8

Answer 10

Puberty and development of secondary sex characteristics
