Analysis of primary visual cortex (V1) under conditions of binocular deprivation by dark-rearing (DR) or monocular deprivation (MD). Animals subjected to DR from birth till postnatal day (P) 27 or to MD from P11-12 to P27. Results provide insight into the role of visual activity in V1 development.

(Submitter supplied) Two key paradigms for examining activity-dependent development of primary visual cortex (V1) involve either reduction of activity in both eyes via dark-rearing (DR) or imbalance of activity between the two eyes via monocular deprivation (MD). Combining DNA microarray analysis with computational approaches, RT-PCR, immunohistochemistry and physiological imaging, we find that DR leads to (i) upregulation of genes subserving synaptic transmission and electrical activity, consistent with a coordinated response of cortical neurons to reduction of visual drive, and (ii) downregulation of parvalbumin, implicating parvalbumin-expressing neurons as underlying the delay in cortical maturation after DR. more...

(Submitter supplied) Visual deprivation, either in the form of dark rearing (DR) or monocular deprivation (MD) are established paradigms for studying cortical plasticity. We have used miRNA microarray to uncover miRNAs whose expression is altered in primary visual cortex following DR and/or MD.

(Submitter supplied) Wild-type (C57Bl6) mice were dark reared from birth to P42, then underwent monocular enucleation at P42. They were then placed in a normal light-dark environment for 4 days, after which they were sacrificed (at P46). Visual cortex was dissected from 1-mm thick coronal sections, and total RNA was extracted from the tissue lysate using Trizol (Gibco-BRL). Keywords: repeat

(Submitter supplied) The role of postnatal experience in sculpting cortical circuitry, while long appreciated, is poorly understood at the level of cell types. We explore this in the mouse primary visual cortex (V1) using single-nucleus RNA-sequencing, visual deprivation, genetics, and functional imaging. We find that vision selectively drives the specification of glutamatergic cell types in upper layers (L) (L2/3/4), while deeper-layer glutamatergic, GABAergic, and non-neuronal cell types are established prior to eye opening. more...
