Decision-making behavior has been studied extensively, but the neurophysiological
mechanisms responsible for this remarkable cognitive ability are just beginning to be …

The discovery of neural signals that reflect the dynamics of perceptual decision formation
has had a considerable impact. Not only do such signals enable detailed investigations of …

Once considered the province of philosophy and the behavioral sciences, the process of
making decisions has received increasing scrutiny from neurobiologists. Recent research …

Perceptual decision making is the act of choosing one option or course of action from a set
of alternatives on the basis of available sensory evidence. Thus, when we make such …

The aim of statistical decision theories is to understand how evidence, prior knowledge, and
values lead an organism to commit to one of a number of alternatives. Two main statistical …

Neurons in early sensory cortex show weak but systematic correlations with perceptual
decisions when trained animals perform at psychophysical threshold. These correlations are …

Introduction Studies of categorical decision-making attempt to understand behavior by
probing how different features of complex and changing environments guide the selection of …

Perceptual decisions are made when sensory evidence accumulated over time reaches a
decision threshold. Because decisions are also guided by prior information, one important …

Decision making refers to the ability of humans and other animals to choose between
competing courses of action based on the relative value of their consequences. This …

This article reviews recently proposed theories postulating that, during simple choices, the
brain performs statistically optimal decision making. These theories are ecologically …
