Ontogeny of cortical synaptic depression underlying olfactory sensory gating in the rat.
Sensory gating is the ability to filter irrelevant or redundant sensory input and is a critical function of all sensory systems that allows efficient processing of important stimuli. The present results demonstrate that a form of activity-dependent synaptic depression recently found to be involved in both cortical and behavioral olfactory sensory gating, is functional by at least the first postnatal week in the rat piriform cortex, and shares a common metabotropic glutamate receptor mechanism.
