Neurogliaform cells dynamically regulate somatosensory integration via synapse-specific modulation

Nat Neurosci. 2013 Jan;16(1):13-5. doi: 10.1038/nn.3284. Epub 2012 Dec 9.

Abstract

Despite the prevailing idea that neurogliaform cells produce a spatially unrestricted widespread inhibition, we demonstrate here that their activity attenuates thalamic-evoked feed-forward inhibition in layer IV barrel cortex but has no effect on feed-forward excitation. The result of this circuit selectivity is a dynamic regulation in the temporal window for integration of excitatory thalamic input, thus revealing a new role for neurogliaform cells in shaping sensory processing.
