Alzheimer’s Disease Leads To Loss Of Visual Memory: Study
According to a new MIT study, Alzheimer's disease affects at least one type of visual memory by deteriorating a recently discovered circuit that connects the image processing areas of each brain hemisphere. The findings, published in the journal Neuron by a research team at The Picower Institute for Learning and Memory, come from experiments in mice, but provide a physiological and mechanistic basis for earlier observations in human patients: reductions in the level of brain rhythms between counterpart regions in each hemisphere correlate with the clinical severity of dementia. Author Chinnakkaruppan Adaikkan, assistant professor in the Centre for Brain Research at the IISc said, "We demonstrate that there is a functional circuit that can explain this phenomenon. In a way we uncovere...
