Q

Do we have more neurons at birth or as an adult

A

Birth.

We lose neurons due to their inefficiency or damage but as we grow, we grow new branches on dendrites and produce more or less neurotransmitters and receptors.

the hippocampus

amygdala

hypothalamus

A

amygdala

20
Q

the amygdala calculates our

physical reaction to a stimulus

emotional value and intensity of a stimulus

A

emotional value and intensity of a stimulus

21
Q

what happens to an animal if they have an amygdalectomy? humans?

A

They become docile and snuggle up to the thing they used to be afraid of.

Q

the hippocampus is responsible for

motor skills

filtering emotional stimulus

forming new memories

fear response

A

forming new memories

26
Q

what is the task of the frontal lobe

A

decision making and movement (even encodes personality)

27
Q

A

houses primary neurons to initiate movement (corticospinal and corticobulbar)

28
Q

Which of the following is not a fact of the prefrontal cortex

houses 14%-17% of neurons

is not “go” on “stop” and functions by “if ,then” decisions

dysfunction of system is correlated with “negative symptoms” schizophrenic patients (social withdrawal)

A

TRICK QUESTION LOSER ALL OF THEM ARE NECESSARY

29
