Journal ArticleDOI
Low-dimensional dynamics for working memory and time encoding.

TL;DR: This work develops analyses to parcellate neural activity into computationally distinct dynamical regimes and finds that low-dimensional trajectories provide a mechanism for the brain to solve the problem of storing information across time while simultaneously retaining the timing information necessary for anticipating events and coordinating behavior.
Journal ArticleDOI
Neural variability in premotor cortex is modulated by trial history and predicts behavioral performance.

TL;DR: This study studies the influence of recent experience on motor decision making by analyzing the activity of neurons in the dorsal premotor area of two monkeys performing a countermanding arm task and reveals that the across-trial variability of the neural response strongly correlates with trial history-dependent changes in reaction time.
Journal ArticleDOI
Evidence against perfect integration of sensory information during perceptual decision-making
TL;DR: This work presented subjects with a variant of the classic constant-coherence motion discrimination (CMD) task in which brief motion pulses were inserted and examined the effect of these pulses on reaction times in two conditions: when the CMD trials were blocked and subjects responded quickly and when the same CMD Trials were interleaved among trials of a variable-motion coherence task that motivated slower decisions.
Journal ArticleDOI
Motor cost influences perceptual decisions
TL;DR: A psychophysical experiment in which human subjects were presented with a random dot motion discrimination task and asked to report the perceived motion direction using movements of different biomechanical cost found that the pattern of decisions exhibited a significant bias towards the movement of lower cost, even when this bias reduced performance accuracy.
Journal ArticleDOI
An embodied biologically constrained model of foraging
Giovanni Maffei,Diogo Santos-Pata,Encarni Marcos,Martí Sánchez-Fibla,Paul F. M. J. Verschure +4 more
TL;DR: DAC-X is proposed, a novel cognitive architecture that unifies the theoretical principles of DAC with biologically constrained computational models of several areas of the mammalian brain and supports complex foraging strategies through the progressive acquisition, retention and expression of task-dependent information.
