Fig. 8: Discretized representations predict orientation discrimination performance: schematic summary of the results.
From: Discretized representations in V1 predict suboptimal orientation discrimination
The activity of neurons (colored circles) evoked by different oriented stimuli (black arrows) is indicated by their opacity. The different colors correspond to different preferred orientations. The scales on the right symbolize the suggested integration mechanism that computes a probability that the stimulus is the Go by integration the activity coming from discrete and invariant preferred orientation domains. In the V1 of naïve animals, the orientations of the presented stimuli are continuously and accurately represented while in trained animals the suppression of task-value-flanking neurons (neuronal excitability, in yellow) restricts the activity into discrete domains.
