Final Review

Question 1

Neuroplasticity

Answer 1

brain continues to change in response to experience or environment

Question 2

Casual Inference

Answer 2

does this (in brain) cause that (Behavior)

Question 3

Myelin

Answer 3

Oliodentricites and Schwann (glial cells) cells wrap around axons to form this myelin which is fatty insulin to help speed up AP

Question 4

Basal Ganglia

Answer 4

Control movement and procedural learning. Forebrain nuclei.

Question 5

Amygdala

Answer 5

limbic system; process fear emotions and learning wrapped around Basal Gangli. Emotional regulation and perception of odor.

Question 6

Hippocampus

Answer 6

limbic; learning/memory. change some memories from non declarative short term to long term

Question 7

Hypothalamus

Answer 7

hunger, thirst, temperature, sex. control pituitary gland and helps brain interface with hormonal systems

Question 8

Equilbrium potential

Answer 8

electric charge is at one that completely balances gradient this is in resting potential

Question 9

threshold

Answer 9

cell gets to -40mV (after diff ions come in and change gradients) and starts AP

Question 10

AP what happens to charges

Answer 10

rapid reversal of membrane potential. Inside becomes positive and outside negative. Produced down axon hillock between myelin sheath

Question 11

Synaptic Vesicles

Answer 11

structure ball that carries the NT and binds to the presynaptic wall via Ca ions to let out NT to synapse

Question 12

Nicotine

Answer 12

compound in tobacco; agonist on cholinegic receptors. stimulant that increases heart rate and blood pressure

Question 13

Alcohol

Answer 13

Depresant drug. First stimulant then depressant of neural activity. Attach to GABA receptors decreases anxiety

Question 14

THC

Answer 14

Depressant. Brain has cannaboid receptors for THC

Question 15

Caffeine

Answer 15

Blocks adenosine receptors NT increase and brain activity increase

Question 16

Bipolar Cell

Answer 16

neuron in retina that detects light contains rods (shapes) and cones (color) send info to ganglion cell

Question 17

Optic Nerve

Answer 17

made up of ganglion cell axons. carries info to occipital cortex

Question 18

photoreceptor adaptaion

Answer 18

rods/cones adjust to light sensitivity and changes in brightness

Question 19

Fovea

Answer 19

highest density of photoreceptors in retina containing only cones

Question 20

receptive field

Answer 20

particular part of body surface stimulus will trigger neuron firing of based on what sense too

Question 21

Circadian Rythms

Answer 21

behavioral and chemical rhythms that last one day

Question 22

SCN

Answer 22

suprachiasmatic nucleus–subregion of hypothalamus. Region is biological clock because the metabolic activity of neurons align with light and dark of outside world.
