Neuronal activity elicited by figure-ground stimuli in primary visual cortex of the awake mouse

Figure-ground segregation is the process by which the visual system identifies image elements of figures and segregates them from the background. This dataset of electrophysiological recordings in V1 of awake mice revealed that the responses elicited by figures were stronger than those elicited by the background and even stronger at the edge between figure and background. A figural response could even be evoked in the absence of a stimulus in the V1 receptive field. Current-source-density analysis suggested that the extra activity was caused by synaptic inputs into layer 2/3. The results of the dataset were published (see related publications).
