Neurotransmitters and Their Relation to Intelligence Essay

Neurotransmitters and Their Relation to Intelligence - Essay Example Wechsler (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 neurological perspective, the anatomical localization of the neurological processes that give rise to intelligence is generally considered to be the Wernicke's area, located in the superior temporal gyrus, an area of the brain not 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 higher intellectual functions when their Wernicke's 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 the 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.

Since the latter years of the twentieth century, it has become humdrum for critics to announce that the world we live in is an information society. Therefore, if this is wholly genuine, then we must certainly have key ramifications for the information sciences. It is beyond hesitation that social concerns impinge upon the work of information intellectuals and professionals similarly. As we look at the definitions of what an information society is, it is important that we first put into account the nature of, and standard for, an information society (Bawden & Robison, 2012). According to Bawden and Robinson (2012), the most objective perception of the information society is founded on economics. Thus, when most of the economic activity and assets of a community is based on insubstantial, information based goods and products, then it appears justifiable to explain this as an information society. An analogous case is founded on occupations. Bowen and Robison (2012), assert that when people are employed as information employees, as opposed to manual workers, then the community should be termed as an information society. Whereas these economic and occupational assumptions appear collectively persuasive, they have been dismissed on a number of grounds, most specifically since supporters of the perceptions have the tendencies to espouse a vague, and may be irrationally extensive perceptions of what may be considered as information society. Bawden and Robison (2012), thus far argues that this is an option, and may be the most popular explanation based on technology. When a community has adequately dominant and extensive information and communication technologies,
