Sensory inputs control the integration of neurogliaform interneurons into cortical circuits

Neurogliaform interneurons constitute an essential component of cortical circuits. This paper provides evidence that, during early development, superficial neurogliaform cells of the primary somatosensory barrel field cortex receive prominent innervation from the thalamus. These afferents also activate postsynaptic NR2B-containing NMDA receptors, which are essential for the neurons' proper cortical integration.
