Flashcards in Neurotransmitters involved in learning Deck (13):
1

Define: neurotransmitter

a chemical substance produced by a neuron that carries a message to other neurons or cells in muscles and glands.

2

What has to be special about the receptor sites?

They must be complementary (matching) to the neurotransmitter.

3

Define: excitatory neurons

activate postsynaptic neurons and consequently strengthen the connection between them.

4

Define: inhibitory neurons

prevent postsynaptic neurons from firing.

5

Main 2 neurotransmitters in learning?

Glutamate and dopamane.

6

Which is THE main excitatory neurotransmitter in learning?

Glutamate?

7

WHen is glutamate secreted?

In learning - it binds to the postsynaptic neuron. This means they are activated at the same time, and therefore it strengthens synapses.

8

What are the main two types of glutamate receptors?

AMPA and NMDA receptors.

9

Define: AMPA receptor

activates the postsynaptic neuron

10

Define: NMDA receptor

produces long-lasting modifications to the synapse.

11

WHAT stimulates dopamine?

After the repeated release of glutamate, which stimulates the secretion of dopamine.

12

When is dopamine secreted?

WHen doing an activity that provides a reward - creates the feeling of pleasure.

13

How does dopamine contribute to the strengthening of synapses?

Causes more dendritic spines to grow from the post-synaptic neuron
