What does the pons do?

A

Connects the cerebellum to the rest of the brain. Sleep, arousal, and facial expressions. Bridges higher and lower portions of brain

21

Body’s master gland, growth hormones

A

pituitary gland

24

Emotional processing. Identifying, remembering, and responding to fear and aggression

25
Q

What two structure groups make up the forebrain?

A

Subcortical and cerebral cortex

26
Q

What does the medulla do?

Study what parts of the brain are active during a certain task

A

fMRI

28
Q

What is the cingulate cortex?

A

Fold of tissue on inner surface of cerebral hemisphere

29
Q

What does the frontal lobe do?

A

Abstract thinking, planning, judgement, reasoning, problem solving

30
Q

What does the primary motor cortex do?

A

Controls voluntary movement

31
Q

Controls body’s metabolism, activates adrenal glands

A

thyroid gland

32
Q

What does Wernicke’s area do?

A

Speech comprehension

33
Q

Release of hormones into blood, made of glands, involved with arousal metabolism, growth, sex

A

endocrine system

34
Q

What does the basal ganglia do?

A

Involved with voluntary movement. Involved in Parkinson’s, ADHD, and OCD

35
Q

Three parts of autonomic nervous system

A

sympathetic, parasympathetic, and enteric

Q

What is in the frontal lobe?

A

Primary motor cortex and Broca’s area

37
Q

What does Broca’s area do?

A

Production of speech

38
Q

Nerve cells in the lining of the gastrointestinal system. Gastrointestinal pain, hunger, satiety (fullness), interacts with the endocrine system. Tells the brain how you’re feeling

A

Enteric nervous system

39
Q

What does the reticular formation do?

A

Control of mood, arousal, and sleep. Why we don’t respond during sleep but do when awake

40
Q

What is the cerebral cortex?

A

Outermost layer of the brain visible to the naked eye and divided into two parts

41
Q

What does the hippocampus do?

A

Formation of long term memories and spatial information processing

42
Q

Carries involuntary and automatic commands that control blood vessels, body organs, and glands

A

autonomic nervous system

43
Q

Left hem controls right side and right hem controls left side

A

Lateralization

44
Q

What is the forebrain involved in?

A

Highest level of the brain that controls complex cognitive, emotional, sensory, and motor functions

45
Q

What are the subcortical structures?

A

Thalamus, basal ganglia, hypothalamus, hippocampus, cingulate cortex, amygdala, and nucleus accumbens

46
Q

What happens when your left or right hem is damaged? What type of lobe damage?

A

You stop taking in info from the opposite side of the body. Parietal lobe damage

47
Q

Studying behavior before and after brain damage

A

lesion studies
