eLife Assessment: Readout and delayed transmission of initial afferent V1 activity in decisions about stimulus contrast

This important study reports that EEG recordings of the earliest stage of information processing in human visual cortex can be used to predict subsequent choice responses.The findings provide novel, convincing evidence for integrative processing in low-level sensory cortices at the level of scalp-recorded potentials, with the exact nature of the neural signals at the single cell level to be determined.The paper is likely to be of interest to neuroscientists interested in the contribution of early sensory signals to decision making.
