A role for neural integrators in perceptual decision making.
Decisions based on uncertain information may benefit from an accumulation of information over time. We asked whether such an accumulation process may underlie decisions about the direction of motion in a random dot kinetogram. To address this question we developed a computational model of the decision process using ensembles of neurons whose spiking activity mimics neurons recorded in the extra...
متن کاملTitle: Neural Integrators for Decision Making: a Favorable Tradeoff between Robustness and Sensitivity Abbreviated Title: Neural Integrators for Decision Making
A key step in many perceptual decision tasks is the integration of sensory inputs over time, but fundamental questions remain about how this is accomplished in neural circuits. One possibility is to balance decay modes of membranes and synapses with recurrent excitation. To allow integration over long timescales, however, this balance must be exceedingly precise. The need for fine tuning can be...
متن کاملNeural Stochastic Dynamics of Perceptual Decision Making
Recent studies have identified some brain regions involved in the decision process for simple perceptual tasks, and have provided insight into how sensory information is evaluated before the commitment to a motor response. To understand the dynamical principles of the decision process, and how they emerge from the interaction of interconnected neurons, computational models have been proposed ba...
