Abstract Deep brain stimulation (DBS) is a promising neuromodulation therapy, but the neurophysiological mechanisms of DBS remain unclear. We performed high-speed membrane voltage fluorescence imaging individual hippocampal CA1 neurons during delivered at 40Hz or 140Hz, free electrical interference, in awake mice. discovered that reliably depolarizes somatic potentials without suppressing spike...

progressive cognitive decline is one of the hallmark symptoms of alzheimer’s disease (ad) which can be modeled by β-amyloid injection into specific regions of brain. since epigallocatechin-3-gallate (egcg) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether egcg administration protects against β-am...
