The Effect of Neurotransmission on Human Behavior

1. 2 Using ane or more examples, pardon effects of neurotransmission on merciful demeanor Our nervous systems consist of between 10 to 100 billion neurons separately of which making 13 trillion connections with each other through electrochemical messages that allow people to respond to stimuli, from the environment or from internal changes in a persons body. The neurons send these electrochemical messages through neurotransmission.Electrical impulses travelling down the axon (body) of a neuron, instigates the release of neurotransmitters, which travel over the synapse, which is the break of serve between two neurons. Once the neurotransmitters cross the synapse, they go into receptor internet sites on the post-synaptic membrane of a neuron, and aft(prenominal) having passed on the message, they are either disquieted down or reabsorbed by the terminal buttons of the neuron, in a act known as reuptake. Neurotransmission has been shown to affect a large range of human behavi ours.Serotonin is a neurotransmitter that effects sleep, arousal levels, and emotion. In a 1999 study at Tokyo University, its effects were seen. Kasamatsu and Hirai conducted this study in order to examine the charge that sensory deprivations affects the brain. They studied a group of monks going on a 72-hour pilgrimage without food or water. The monks endured the weather without shelter from the cold, and didnt declaim among themselves. Two thirds of the way through the pilgrimage, the hallucinations began, taking the shape of ancient ancestors, or just a presence at their side.Blood samples, taken immediately after the monks reported their hallucinations, were compared to blood samples taken prior to the pilgrimage, and showed change magnitude serotonin levels. These increased serotonin levels activated the hypothalamus and the frontal cortex, causing the monks hallucinations. Kasamatsu and Hirai were competent to conclude that sensory deprivation caused increase in serotonin levels, which adapted the monks perception and behavior. Neurotransmitters, like serotonin, notify play a large character reference in human behavior.However, it is considered reductionist to rely solely on them to explain human behavior they only play a role and cant be held fully responsible for behavior. Research and increased intimacy of neurotransmission has led to the development of drugs that can either simulate a neurotransmitter in the case of a deficiency, or block a receptor site if there are excessive neurotransmitters. Understanding how neurotransmitters can affect behavior has led to the development of these drugs, which have helped many people.
