Topic: visual motion discrimination

Perceptual decision-making has often been studied using sensory-to-motor transformation tasks. Shushruth et al. (2022) showed in a visual motion discrimination task (Fig. A) that neurons in the lateral intraparietal cortex (LIP) of two monkeys exhibited delayed evidence-based responses, activating only upon choice target onset after the motion stimulus (Fig. B-C). The LIP neurons were hypothesised to have retrieved information via short-term memory. However, how this was achieved remains unclear.In this work, we extended the nonlinear mean-field model of Wong and Wang (2006) by incorporating a

Sleep deprivation is known to drastically affect cognitive function including decision-making and attention across many different species. In this study, we leveraged the small size and conserved brain structure of larval zebrafish to investigate the consequences of sleep deprivation in the context of two well-described behaviors, a visual and an olfactory-based decision-making task. We find that in both paradigms, sleep deprivation leads to an improvement in performance. Specifically, we show that sleep deprivation increases reaction time and improves performance in a visual motion discrimina
