neurotransmission

Question 1

Reuptake and Affect on Neurotransmission

Answer 1

Reuptake is the process by which neurotransmitters are taken back up by the pre-synaptic cleft after release. This allows control over the neurotransmitters in the brain.

Question 2

Drug Affect on Neurotransmission

Answer 2

Increases the release of dopamine to the brain which leads to increased activity in the reward system.

Question 3

Neurotransmission

Answer 3

The process of communication between neurons through the use of chemical messengers called neurotransmitters.

Question 4

Neurotransmission Process

Answer 4

1. Creating neurotransmitters
2. Store neurotransmitters in vesicles
3. Neuron sends action potential down axon
4. Calcium bursts vesicles and neurotransmitters are released into the synaptic clef
5. The neurotransmitters stick to receptors on the post synaptic neuron where they send an electrical signal to the next neuron.

Question 5

Cocaine Affects on Neurotransmission

Answer 5

Blocks reuptake of neurotransmitters like dopamine, leading to increased levels in the synapse and intensified effects.

Question 6

Meth Affects on Neurotransmission

Answer 6

Causes excessive release of neurotransmitters, particularly dopamine, resulting in intense and prolonged stimulation.

Question 7

Dopamine

Answer 7

A neurotransmitter known for pleasure, reward, motivation and movement control.

Question 8

Release of Dopamine

Answer 8

Released when behaviours aiding survival (eating) occur. It motivates repetition of these actions.
