Coordinated developmental recruitment of latent fast spiking interneurons in layer IV barrel cortex

Daw, Michael I, Ashby, Michael C, Isaac, John T R·2007·Nature Neuroscience

Abstract

Feedforward inhibitory GABAergic transmission is critical for mature cortical circuit function; in the neonate, however, GABA is depolarizing and believed to have a different role. Here we show that the GABAA receptor-mediated conductance is depolarizing in excitatory (stellate) cells in neonatal (postnatal day [P]3-5) layer IV barrel cortex, but GABAergic transmission at this age is not engaged by thalamocortical input in the feedforward circuit and has no detectable circuit function. However, recruitment occurs at P6-7 as a result of coordinated increases in thalamic drive to fast-spiking interneurons, fast-spiking interneuron-stellate cell connectivity and hyperpolarization of the GABAA receptor-mediated response. Thus, GABAergic circuits are not engaged by thalamocortical input in the neonate, but are poised for a remarkably coordinated development of feedforward inhibition at the end of the first postnatal week, which has profound effects on circuit function at this critical time in development.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
