Saq on Two Psychologically Relevant Theories
Explain, using examples, the effects of neutransmission on human behaviorNeutransmission is a process in the brain by which the signaling molecules, those, we call neutransmitters, are released by a neuron to afterwards bind to and activate the receptors of another neuron. Serotonin is one amongst many neurotransmitters in the human brain. Serotonin is very much associated with both depression and aggression and is a body regulator which controls important activity in the brain such as sleep and body temperature. Kasamatsu and Hirai conducted an experiment in 1999 with the aim of finding out how sensory deprivationaffects behavior. This was done by studying a group of Buddhist monks on the pilgrimage to Japan. They didn’t consume food or water and the researchers took a blood sample before they started their trip. The results of this, followed by the fact that the monks started having hallucinations, ended up with a conclusion that sensory deprivation had an effect on the release of serotonin, altering the way the monks experienced the world. In addition, acetylcholine is another neurotransmitter in the human brain.

Acetylcholine is involved with how we learn as well as our memory. Acetylcholine also has an effect on our heart rate and production of saliva. Martinez & Kesner conducted an experiment in 1991 with the aim of trying to determine the role of acetylcholine on memory. They did this by training rats to go through mazes with the aim of finding the food. When they were able to do so, 3 groups were injected with different kinds of chemicals and the findings were, in relation to acetylcholine, that it played an important role in creating a memory of the maze.Explain one study of localization of function in the brainAphasia is the definition of a variety of language disorders caused by brain damage. Aphasia entails the loss of speech although your intelligence still works. You can not, however, show any signs of intelligence due to the lack of mobility and language.In 1861, Pierre Paul Broca conducted a study on a 51-year-old man who died in his care at BicĂŞtre hospital in France. The 51-year-old-man, Tan, which his family named him due to his constant word use of the latter, had lost the use of speech due to a brain infection. Tan started out loosing movement in his right arm as well as becoming unable to pronounce more than a single syllable.
