Effects of Neurotransmission on Human Behaviour
A neurotransmitter is a chemical message that carries signals from one neuron (pre-synaptic) to another reaction neuron (post-synaptic) within the human body. Most of the time a neurotransmitter is released from the axon terminal after an action potential has reached the synapse. The neurotransmitter then crosses the synaptic gap to reach the receptor of the other cell. The process repeats itself, which then causes a. Neurotransmitters play a very important role in every day life and functioning.
There are two types of neurotransmitters – excitatory neurotransmitters and inhibitory neurotransmitters. Excitatory Neurotransmitters make the post- synaptic neuron more likely to generate an action potential, whilst the inhibitory neurotransmitters are chemicals released by neurons that suppress the activity of other neurons. When a neuron binds to an inhibitory neurotransmitter, it becomes less likely to fire an action potential. A few examples of neurotransmitters would be dopamine, serotonin, and acetylcholine.
Dopamine is a neurotransmitter that affects neurons in the brain that control voluntary movement, learning, and the ability to experience pleasure. Having excess amounts of dopamine might eventually lead to people having schizophrenia. Schizophrenia is a mental disorder that makes it hard to think logically, tell the difference between what is real and unreal, have normal emotional responses, and to act normally in social situations. EMPHASIZE different effects of dopamine. Having a deficiency in dopamine can also cause a neurological disorder know as the Parkinson’s disease. Parkinson’s disease can lead to shaking, difficulty in walking, movement and coordination. Unfortunately, both of these mental disorders cannot be cured, but they can be treated. Certain drugs and medication can be used on the patients that have schizophrenia or Parkinson’s disease. that dopamine can either be blocked from being...
