Question 1

what are the three stages of brain development

Answer 1

conception
early development
adolescent development

Question 2

what age is the brain 90% of the adult brain size

Answer 2

2 yrs

Question 3

what is synaptogenesis

Answer 3

synaptic connections increasing and increased dendritic branching

Question 4

what age is there peak O2 consumed in the brain

Answer 4

age 5

Question 5

what happens to grey matter during brain development

Answer 5

cortical thickness decreases
synapses are rearranged and pruned to increase efficiency

Question 6

what happens to myelination during brain development

Answer 6

myelination increases to increase connectivity and efficiency

Question 7

what are the three main criteria for autism spectrum disorder

Answer 7

A. persistent deficits in social communication
B. restricted repetitive patterns of behaviors, interests
C. present during early development

Question 8

how does the synaptic pruning and neural connectivity differ in those with autism spectrum disorders

Answer 8

may have more synapses (less efficient synaptic pruning)
higher levels of neural connectivity
