Expression of ptau in hippocampal tissue and navigational abilities in mice

Abstract

In Alzheimer’s disease, neural tissue is damaged by the accumulation of beta amyloid and tau proteins. Often, so much of these proteins has accumulated before a diagnosis is reached that tissue has already been significantly damaged. One of the first abilities impaired in Alzheimer’s is the ability to navigate or remember spatial information. Research has found that using 40Hz stimulation in the brain has lowered beta amyloid and tau levels. In an effort to rescue this tissue and assist in memory longevity, mouse subjects were set to perform a series of navigation and spatial information tasks paired with 40Hz stimulation. Mice underwent surgeries in which neural implants were attached through which 40Hz stimulation could be delivered to specific brain regions. Following completion of the task amyloid beta and tau levels were assessed in the region where 40Hz stimulation was delivered. Surprisingly, despite rescued behaviour and brain dynamics, we found that Tau levels were not reduced by 40Hz stimulation.
