Question 3

Neurotransmitters theory

Answer 3

Neurotransmitters are chemical messengers which allow for communication in the brain. Neurotransmitters are located within vesicles in neurons. They are released from vesicles once the action potential within the axon reaches the terminal button. The action potential stimulates the vesicle to release neurotransmitters into the synaptic gap - they bind to receptors on the postsynaptic neuron. If the neurotransmitters are antagonists they will make the next neuron less likely to fire, if they are agonist they are more likely to fire. One behaviour affected by neurotransmitters is memory in Rogers and Kesners study, we see the effects of blocking the neurotransmitter of acetylcholine. And how that affects spatial memories in the hippocampus.
