Q

What is the posterior association in charge of?

A

It recognizes patterns and faces, it localizes us in space, it binds sensory inputs into coherent whole, and it controls language

23
Q

What is limbic association in charge of?

A

It controls emotional impact, your sense of danger, and your memory to remember them

A

Insight, visual-spacial skills, intuition, and artistic skills

26
Q

What side of the brain is responsible for language? What side is responsible for body language?

A

The left side of the brain is responsible for language, and the right side is in charge of body language

27
Q

What are some examples of homeostatic imbalances in the brain? *

A

Traumatic brain injury, cerebrovascular accidents, and degenerative brain disorders
