REVEALED: Role of brain circuits in improving learning and memory- see here!!


University of California, Irvine-led team of experimenters has discovered how the newly identified neural circuits in the brain’s hippocampal formation play a critical role in object-location learning and memory.

The study, disseminated today in Nature Neuroscience, was led by Xiangmin Xu, Ph.D., anatomy and neurobiology prof. In the University of California School of Medicine, and performed in collaboration with Douglas A. Nitz, PhD, professor and chair of the Department of Cognitive Science at the University of California, San Diego; Qing Nie, PhD, Chancellor’s Professor of analyses and developmental and cell biology at University of California; and, Todd C. Holmes, the teacher and vice-chair of University of California’s Department of Physiology & Biophysics.

Loss of object location recollection is one of the key damage in Alzheimer’s disease (AD), the most widespread form of dementia in the elderly. These new conclusions in hippocampal circuit agencies furnish an interesting new mark to equalize AD-related memory impairments.

“Our research was made feasible by new viral genetic-based mapping strategies for assessing connectivity between hierarchies. These new mapping tools facilitated us to specify novel circuits within and between the hippocampus and cortex,” said Xiangmin Xu.

Xu and his colleagues have used monosynaptic hydrophobia retrograde tracing and herpes (H129)-based anterograde tracing to determine the new cortico-hippocampal electronic equipment related to subiculum (SUB) projections to hippocampal CA1. Xu associate degreed a world team of investigators was recently awarded a federal agency BRAIN Initiative grant to develop new H129 microorganism tracers as a brain mapping tool to be used by the entire neuroscience community.

The team unconcealed the hippocampal sub-circuit mechanism extremely relevant to learning and memory disorders as well as Alzheimer’s illness. These findings are also accustomed to higher treat Alzheimer’s illness and alternative medicine disorders, delay their onset, and presumably stop them from developing within the initial place.
