Fig. 5: Modulation of the neuronal excitability in the orientation space.
From: Discretized representations in V1 predict suboptimal orientation discrimination
a Tuning curves of the neurons tuned for 45 ± 7.5° (n = 124, left), 67.5 ± 7.5° (n = 116, center), and 90 ± 7.5° (n = 144, right), recorded during the 90° Go/NoGo angle sessions. Grey dots indicate mean activity, grey vertical lines indicate s.e.m. across neurons. Colored lines and shadows indicate mean tuning curve fit ± s.e.m. across neurons. b Mean amplitude of the tuning curve as a function of the neurons’ preferred orientation for the sessions when the Go/NoGo angle was 90° (shadow indicates s.e.m. across neurons of similar preferred orientation). c Modulation of the neuronal excitability in the orientation space for the sessions with all the different Go/NoGo angles (color code in inset). The shaded area indicates the s.e.m. Black trace: averaged modulation across Go/NoGo angles, fitted with a smoothing spline. d Same as (c) but for the naïve animals. The dashed line shows the average from (c).
