Abstract

Commentary: Sensory integration dynamics in a hierarchical network explains choice probabilities in cortical area MT.

Highlights

The phenomenon of choice probability was first described by Britten et al (1996), who measured firing rates of neurons in area MT that are highly sensitive to visual motion
In this influential study, when a macaque monkey viewed a cloud of moving dots in an effort to determine its dominant direction of motion, the firing rates of single MT neurons were found to predict the decision that the monkey would eventually make

Summary

Introduction

Reviewed by: Klaus Wimmer, Universitat Pompeu Fabra, Spain Daniel A. The phenomenon of choice probability was first described by Britten et al (1996), who measured firing rates of neurons in area MT that are highly sensitive to visual motion. Responses of neurons in sensory regions like area MT are highly variable from trial to trial even when evoked by the same stimulus, while higher-level areas involved in the decision-making process “read-out” this noisy information to form a choice.
