Human Decision-making Takes Multiple Brain Regions Performing Individual Functions

[1 November 2007 - ScienceDaily] The brain, the human supercomputer, might work more like an assembly line when recognizing objects, with a hierarchy of brain regions separately absorbing and processing information before a person realizes what they are seeing, according to new research conducted at the University of Pittsburgh and published in the Oct. 31 edition of the Journal of Neuroscience. Led by Mark Wheeler, a psychology professor in Pitt's School of Arts and Sciences, and conducted at Pitt's Learning Research and Development Center, the research is a step toward mapping the human decision-making process. This study used an innovative technique and analysis to show that human decision-making is a collaboration of brain regions performing individual functions. Future work based on these findings could lead to a better understanding of how decisions--good and bad--are made and the considerations people put into them. More
