Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
… receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, …

Effects of Whisker-Trimming on GABAA Receptors in S1 Cortex
… Layers 2/3 above the deprived and adjacent whisker barrels were located in tangential sections, using patterns of radial blood vessels as fiducial marks. In deprived whisker barrel columns, [3H]muscimol binding to GABAA receptors decreased by 12.8% ± 1.2 (P < 0.001) in layers 2/3 and 11.4% ± …

Examination of neocortical plasticity during forebrain-dependent trace-associative learning tasks
… conditioned stimulus (CS) (i.e., tone or whisker deflection) paired with a salient, unconditioned stimulus (US) (i.e., mild periorbital eyeshock) to elicit an unconditioned response (UR) (i.e., eyeblink). With multiple CS-US pairings, subjects learn to associate the CS with the US and …
