Synaptic Plasticity

Question 1

Define learning

Answer 1

The acquisition of skill of knowledge

Question 2

Define memory

Answer 2

The expression of what you learnt in the past

Question 3

Define neural synapse

Answer 3

The site of communication between adjacent neurons

Question 4

Define synaptic gap

Answer 4

The small space between the axon terminal of a presynaptic neuron and the dendrite of the post synaptic neuron.

Question 5

Define reuptake

Answer 5

When a neurotransmitter doe snot bind to a receiver, it is absorbed back into the presynaptic neuron.

Question 6

Define an expiatory effect of a neurotransmitter

Answer 6

Stimulate or activate post synaptic neurons to perform their functions

Question 7

Define an inhibitory effect of a neurotransmitter

Answer 7

To block or prevent post synaptic neurons from firing.

Question 8

What is glutamate and what are its functions?

Answer 8

A primary Excitatory neurotransmitter in the brain.
Strengthening synaptic connections during learning, memory, thinking and perception.
Counteracts GABA

Question 9

What is GABA what are its functions?

Answer 9

Stands for gamma - amino butyric acid
Works to make post synaptic neurons fire less or stop firing
Without it, postsynaptic neurons would become overactivated and lead to seizures.
Counteracts glutamate

Question 10

Define a neuromodulator

Answer 10

A neurotransmitter that can influence and moderate the effects of other neurotransmitters

Question 11

Define synaptic plasticity

Answer 11

The ability of a synapse to change over time through use or disuse. enables function in the NS
