Explain, using one or more examples, the effects of neurotransmission on human behavior

When a nerve impulse reaches the end of the neuron, the neuron fires and neurotransmitters are released into the synaptic gap where they travel to the neuron at the other side of the synaptic gap.

If the neurotransmitter is not absorbed it can be re-uptaken, diffused out or destroyed. The neurotransmitter then binds to specific receptors at the other side. If a neurotransmitter is blocked or replaced (e.g. because another chemical interferes) then the messages change. This affects the physiological system, cognition, mood, or behavior.

Example 1:

Acetylcholine (ACh) on memory



Study to use: Martinez and Kesner (1991)

Example 2:

Dopamine and Love

Dopamine is a neurotransmitter involved in goal-directed behavior (motivation) such as pleasure seeking, control of movement, emotional response, and addictive behavior. Dopamine is released in the brainís reward system.
