Neural correlates of decision processes: neural and mental chronometry (Fragment)

Jeffrey D Schall Center for Integrative and Cognitive Neuroscience, Vanderbilt Vision Research Center, Department of Psychology, Vanderbilt University, Recent studies aim to explain the duration and variability of behavioral reaction time in terms of neural processes. The time taken to make choices is occupied by at least two processes. Neurons in sensorimotor structures accumulate evidence…

Contributions of the prefrontal cortex to the neural basis of human decision making (Fragment)

Daniel C. Krawczyk* Department of Psychology, University of California, Los Angeles Abstract The neural basis of decision making has been an elusive concept largely due to the many subprocesses associated with it. Recent efforts involving neuroimaging, neuropsychological studies, and animal work indicate that the prefrontal cortex plays a central role in several of these subprocesses….
