Microstimulation V1 and V4 of monkey cortex

Description

This data and analysis produces the figures for the study published as the paper mentioned below. In this study we used electrical microstimulation to reveal distinct signatures of feedforward and feedback connections in the visual cortex of monkeys.

  • Stimulation of V1 and recording in V1 (local) or V4 (feedforward) using Utah arrays.
  • Stimulation of V4 and recording in V4 (local) or V1 (feedback).
  • Stimulation during a visual Figure-Ground task to investigate interaction with the visual response.
