Neurological explanations of decision making in humans: A review Tagaram Kondala Rao * Department of Foundations of Education, Faculty of Education, Dayalbagh Educational Institute, (Deemed to be University) Agra. Uttar Pradesh, India. World Journal of Advanced Research and Reviews, 2022, 14(01), 302307 Publication history: Received on 20 February 2022; revised on 26 March 2022; accepted on 28 March 2022 Article DOI: https://doi.org/10.30574/wjarr.2022.14.1.0265 Abstract The present review paper focuses on neurological perspective of decision making which plays a major role in our daily life. Our success or failure heavily depends up on the decision we make. So, there is a strong connection between decision making and successful life. Decision making is one of the cognitive aspects that give high load to our brain. In processing decisions, neurons and blood oxygen levels play major role. The author tried to explore various brain regions that involved in decision making process in the light of previous research findings. The author has reviewed 50 research papers/dissertations/documents/ review reports and other sources. Most of the researches used brain mapping techniques to explain possible reasons behind decision making. The conceptual understandings of the review have been presented in the following sections. The author came across various types of decision making such as perceptual decision making, social decision making, economic decision making in relation to different brain regions like parietal cortex, medial premotor cortex. These aspects have been discussed and highlighted in the upcoming sections. Keywords: Neuroimaging; Decision Making; FMRI; Parietal Cortex; Medial Premotor Cortex 1. Introduction Neuroscience has been gaining attention of brain researches that would help us reaching some valid scientific conclusion on how people make decisions. Ultimately, those decisions turn into economic models of humans. Many neuroimaging techniques came into existence one after other. Basically, neuroimaging is a quantitative technique that studies structure and functions of central nervous system in an objective way scientifically. The central nervous system includes brain and spinal cord. It is not only limited to medical field, but comes under multidisciplinary studies. Human brain is a complex and highly sophisticated organ. Up to some extent, Neuroimaging techniques help in understanding complex procedures of cognitive functions such as decision making, problem solving, and emotions and so on. Decision making is also said to a complex cognitive process where human selects a best option out of other possible alternative solutions. 1.1. Brief Historical Accounts of Neuroimaging Techniques Angelo Mosso (1846-1910), Italian neuroscientist, the first one for his 'human circulation balance', that measured redistribution of blood during emotional and intellectual activity in non-invasively. Later, Walter Dandy (1918), the American neurosurgeon developed the technique of ventriculography for studying air in one or both lateral ventricles of the brain [1]. He also introduced a technique known as pneumoencephalography to demonstrate cerebrospinal fluid compartments. Cerebral angiography was introduced in 1927 by Egas Moniz to study normal and abnormal vessels in and around brain (2).
