This study finds that the normal development of GABAergic feedforward inhibition in mouse layer 4 barrel cortex is disrupted by whisker trimming. Such sensory deprivation results in a weakened thalomocortical to feedforward interneuron connections and a lack of the normal reduction of the NMDA component of the thalamocortical input to excitatory cells, both of which are important for feedforward GABAergic inhibition.
