Cortical response states for enhanced sensory discrimination

  title={Cortical response states for enhanced sensory discrimination},
  author={Diego A. Gutnisky and C B Beaman and Sergio E Lew and Valentin Dragoi},
Brain activity during wakefulness is characterized by rapid fluctuations in neuronal responses. Whether these fluctuations play any role in modulating the accuracy of behavioral responses is poorly understood. Here, we investigated whether and how trial changes in the population response impact sensory coding in monkey V1 and perceptual performance. Although the responses of individual neurons varied widely across trials, many cells tended to covary with the local population. When population… CONTINUE READING
