Interaction of sensory experience and age in spatial memory performances
During a critical period of postnatal age sensory experience has a profound effect on maturation of visual cortical wiring. Electrophysiological evidence is indicating a substantial effect of visual deprivation on the visual cortical response properties. In this study we evaluated effect of light deprivation during a limited time of postnatal age on two aspects of spatial (working and reference...

متن کاملGhostbursting in sensory cells of electric fish
We give an overview of the analysis of a new type of bursting (“ghostbursting”) seen in pyramidal cells of weakly electric fish. We start with the experimental observations and characterization of the bursting, describe a compartmental model of a pyramidal cell that undergoes ghostbursting and the development of a simplified yet realistic conductance–based model of this cell. This model then mo...
متن کاملEnhanced sensory sampling precedes self-initiated locomotion in an electric fish.
Cortical activity precedes self-initiated movements by several seconds in mammals; this observation has led into inquiries on the nature of volition. Preparatory neural activity is known to be associated with decision making and movement planning. Self-initiated locomotion has been linked to increased active sensory sampling; however, the precise temporal relationship between sensory acquisitio...
متن کاملModeling Active Electrolocation in Weakly Electric Fish
In this paper, we provide a mathematical model for the electrolocation in weakly electric fishes. We first investigate the forward complex conductivity problem and derive the approximate boundary conditions on the skin of the fish. Then we provide a dipole approximation for small targets away from the fish. Based on this approximation, we obtain a non-iterative location search algorithm using m...
