26
Q

presynaptic neuron

A

sending neuron

27
Q

presynaptic neuron functions

A

transforms an electrical signal into the release of chemical messengers that diffuse along the synaptic gap to the post-synaptic neuron

28
Q

what does the membrane of post-synaptic neurons contain

A

proteins called receptors

29
Q

what do the proteins of postsynaptic neurons do

A

interact with neurotransmitters

30
Q

what happens when proteins bind with neurotransmitters

A

they release the neurotransmitters and convert the messages into electrical signals

31
Q

what two types of receptors are critical for the creation of long-term memories

A

n-methyl-d-aspartate (NMDA)
cAMP- response element binding protein (CREB)

32
Q

what two processes are key for synaptic plasticity

A

long-term potentiation (LTP)
long-term depression (LTD)

33
Q

long term potentiation

A

long-lasting increase in synaptic strength in the hippocampus

34
Q

long term depression

A

decreases synapses’ effectiveness

35
Q

through what process does our brain change

A

LTP

36
Q

what process is critical for long-term memory consolidation

A

LTP

37
Q

most common neurotransmitter

A

glutamate

38
Q

what classes of glutamate receptors are ion channels

A

NMDA and AMPA (amino hydroxy-5-methyl-4-isoxazolepropionic acid

39
Q

what happens when receptors bind

A

allow calcium and sodium ions to flow into a cell

40
Q

what strengthens a synapse

A

increasing the number of receptors on the postsynaptic cell

41
Q

what type of ion functions as a second messenger

A

calcium

42
Q

what boosts the concentration of calcium ions inside a postsynaptic cell

A

LTP

43
Q

what depletes the concentration of calcium ions inside the cell

A

LTD

44
Q

neurotrophins

A

stimulate the growth of the synapse and structural elements, stabilizing increased sensitivity to neurotransmitters

45
Q

who identified the six basic emotions

A

Paul Ekman

46
Q

what brain structures are most closely linked with emotions

A

amydala, insula or insular cortex, and the periaqueductal gray (located in the mid brain)

47
Q

where is the periaqueductal gray located in

A

midbrain

48
Q

from what regions do neurons project into the periaqueductal gray

A

from the prefrontal cortex, amygdala, and insula

49
Q

what structure in the brain integrates emotions, emotion, fear, and friends

A

amydgdala

50
Q

what type of learning is dependent on the amygdala

A

classical conditioning

51
Q

classical conditioning

A

associating a stimulus with reward or punishment

52
Q

through which structure do you experience disgust

A

insula

53
Q

through which structure do you experience pain

A

insula

54
Q

structure tied to pain perception and stress response

A

periaqueductal gray

55
Q

receptors for analgesics are located in the

A

periqueductal gray

56
Q

what is the lateral prefrontal cortex responsible for

A

self-regulation

57
Q

reward pathway

A

hippocampus, amygdala, and prefrontal cortex

58
Q

reward pathway

A

mesolimbic pathway

59
Q

what is the mesolimbic pathway a major pathway for

A

dopamine

60
Q

what area in the brain does the mesolimbic pathway link

A

ventral tegmental area in the midbrain

61
Q

what is the nucleus accumbens involved in

A

cognitive processing of rewards and motivation

62
Q

what two areas in the brain are known to impact motivation and reward

A

striatum and prefrontal cortex

63
Q

major node in reward circuitry

A

lateral habenula
