Training promotes the recovery of electrophysiological measures of reduced neural discriminability following sound exposure.
These findings suggest that PV+ cells regulate perceptual learning, "for better and for worse".
Learning led to region-specific changes in cholinergic neurotransmission, as detected by PET imaging and immunohistochemistry.
'Manipulating a specific type of neuron in the auditory cortex of rats can restore their brain plasticity.' ~ Futurity
'They say you can’t teach old dogs new tricks, but new research shows you can teach an old rat new sounds' ~ NeuroscienceNews
The quality and quantity of sensory inputs reaching the brain influence the rules of plasticity within cortical sensory areas
Combining auditory training with neuromodulation can restore many of the functional deficits observed as a result of normal aging.
