V1-origin Bidirectional Plasticity in Visual Thalamo-ventral Pathway and Its Contribution to Saliency Detection of Dynamic Visual Inputs.

ABSTRACT: Visual neural plasticity and V1 saliency-detection are vital for efficient-coding of dynamically changing visual inputs. However, how does neural plasticity contribute to saliency-detection of temporal-statistically distributed visual stream remains unclear. Therefore, we adopted randomly presented but unevenly distributed stimuli with multiple orientations, and examined the single-unit responses evoked by this biased orientation-adaptation protocol, by single-unit recordings in the visual thalamo-ventral pathway of cats (of either sex). We found neuronal responses potentiated when the probability of biased orientation was slightly higher than other non-biased ones, and suppressed when the probability became much higher. This single-neuronal short-term bidirectional-plasticity is selective
