Vibrissae trimming during the first 20 days of postnatal life caused alternations of the properties of the receptive fields of single neurons in the barrel-field cortex in rats. The following changes were found in the deafferented cortex: (i) an extension of the receptive fields of single neurons as judged from an increase in the number of vibrissae with short-latency excitatory responses to stimulation and (ii) a depression of the inhibitory receptive field tuning mechanisms.
