Neurotransmitters and Their Relation to Intelligence Essay

Neurotransmitters and Their Relation to Intelligence - Essay ExampleWechsler (1944) sets the more widely accepted definition, as he describes intelligence as the aggregate or global capacity of an individual to act purposefully, to think rationally, and to deal effectively with his environment. From a neurologic perspective, the anatomical localization of the neurological processes that give rise to intelligence is generally considered to be the Wernickes area, located in the superior temporal gyrus, an area of the brain non only related to language and speech, but also to logical and abstract thought. This was determined by research done on patients that have lost their high intellectual functions when their Wernickes area. Guyton claims that the prefrontal association area is also associated with intelligence, but not to a great extent.Neurotransmitters in essence represent chemical messengers of the neural circuits and pathways, and in combination with the synapses, represent t he physiological method of communication between neurons. In the synapses, the neurotransmitter is released from a pre-synaptic neuron and bonds with receptors on the post-synaptic neuron. It should be noted that there are many types of neurotransmitters, each found in specific areas of the nervous system and therefore, each has a specific action.
