Abstract
Retinal degeneration (Rd) is a neurodegenerative disorder primarily associated with the degeneration of the retina neurons and culminates in the eventual loss of visual perception or blindness. Decrease in fronto-, parietal and occipital brain connectivity have been reported in a number of neurodegeneration diseases involving cognitive decline. However, cortical communication in the brain of retinal degeneration patients remains largely unknown and strategies to remediate observed dysfunctional brain connectivity in such instance have not be thoroughly investigated. We used rd10 mice as a model to study brain connectivity in the human retinal degeneration disease, retinitis pigmentosa. Rd10 mice with sham matched controls were electrically stimulated at varying stimulation frequencies and the consequent perturbations in feedforward brain connectivity were studied in the visual cortex and pre-frontal cortex using electrocorticography (ECoG) and normalized symbolic transfer entropy (NSTE). Contra Vcx - contra PFx feed forward connectivity significantly (p<0.05) increased in theta, alpha and beta oscillatory bands of 2 Hz and 10 Hz stimulated rd10 respectively in comparison with sham group. Also, this increase was significantly maintained even after the end of the stimulation period.
