Abstract: Retinal horizontal cells (HCs) form a broad receptive field, which contributes to generating antagonistic surround responses in retinal bipolar cells. Here I report that certain HCs themselves have center-surround antagonistic receptive fields. The receptive fields… read more here.

Abstract: Many species of animals exhibit an intuitive sense of number, suggesting a fundamental neural mechanism for representing numerosity in a visual scene. Recent empirical studies demonstrate that early feedforward visual responses are sensitive to numerosity… read more here.
