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). Cormack and Hounsfield (1970) who won Nobel Prize for Physiology or Medicine in 1979 for
