Distinct prestimulus and poststimulus activation of VTA neurons correlates with stimulus detection.

abstract：:Under constant light-adapted conditions, vision seems to be rather linear. However, the processes underlying the synaptic transmission between cones and second-order neurons (bipolar cells and horizontal cells) are highly nonlinear. In this paper, the gain-characteristics of the transmission from cones to horizontal c...
