Decision making can be defined as the flexible integration and transformation of information
from the external world into action. Recently, the development of novel genetic tools and …

Organisms make two types of decisions on a regular basis. Perceptual decisions are
determined by objective states of the world (eg, melons are bigger than apples), whereas …

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 decision making in monkeys relies on decision neurons, which accumulate
evidence and maintain choices until a response is given. In humans, several brain regions …

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 decision-making, the process of using information from our senses to guide
behavior, is successfully described by evidence accumulation, where noisy sensory …

The study of decision making poses new methodological challenges for systems
neuroscience. Whereas our traditional approach linked neural activity to external variables …

There is a growing appreciation of the multiple social and nonsocial factors influencing the
foraging behavior of social animals but little understanding of how these factors depend on …

Sensory systems provide organisms with information on the current status of the
environment, thus enabling adaptive behavior. The neural mechanisms by which sensory …

Categorical choices are preceded by the accumulation of sensory evidence in favor of one
action or another. Current models describe evidence accumulation as a continuous process …
