Cool Paper: “Homeostatic plasticity drives tinnitus perception in an animal model.”
Another cool paper has come out presenting animal research on the patho-physiology (abnormal physiology) that produces tinnitus. The abstract reads fairly easily:
Hearing loss often results in tinnitus and auditory cortical map changes, leading to the prevailing view that the phantom perception is associated with cortical reorganization.However, we show here that tinnitus is mediated by a cortical area lacking map reorganization.
High-frequency hearing loss results in two distinct cortical regions: a sensory-deprived region characterized by a decrease in inhibitory synaptic transmission and a normal hearing region showing increases in inhibitory and excitatory transmission and map reorganization.
The region deprived … Continue Reading
