Fig. 4: In a ferret with 3 days of visual experience, 6 h of experience with a phase-scrambled grating pattern caused an increase in direction selectivity rather than selectivity for the phase-scrambled pattern.
From: An early phase of instructive plasticity before the typical onset of sensory experience
The eyes opened naturally on day P33, and the experiment was performed at P36. Panels a–l are as described in Figs. 2, 3. S4 was used as the training stimulus. In this animal, some cells were tracked across time and Greek letters appear more than once. N = 170 cells before and N = 267 cells after for measurements of F, B, S1–6, CP1–2, and N = 124 cells before and N = 371 cells after for direction tuning. This animal exhibited decreased selectivity to training stimulus S4, and exhibited a significant increase in direction selectivity.
