Researchers have created a new model that may help explain how the brain stores memories of tangible events. The new model explains how neural activity in the hippocampus can help map space, time and context in episodic memories.
Hippocampal neurons become longer and stronger following a period of sleep deprivation. The study supports the hypothesis that sleep may weaken synapses, which are strengthened from learning, allowing for learning to occur after waking.
Researchers have discovered an unexpected diversity within CA1 pyramidal neurons in the hippocampus.
MIT researchers have identified a brain network that allows the brain to record memories of new places.
A new study implicated interneurons and pyramidal cells in the ability of a seizure to spread through the brain.
A lack of oxygen as a result of preterm birth does not cause hippocampal neurons to die but does impair hippocampal development. Hypoxia causes hippocampal cells to fail to mature normally, causing a reduction in long-term potentiation and impaired learning.
Researchers discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can help explain our ability to remember and sort information. The newly discovered gatekeeper nerve cells, also called OLM-alpha2 cells, provide an explanation to how the flow of information is controlled in the hippocampus.
A lack of adaptability in hippocampal place cells could be key to memory deficits in schizophrenia, researchers report.
Researchers report that by increasing the excitability of a subpopulation of hippocampal inhibitory neurons, certain behavioral symptoms associated with schizophrenia can be suppressed.
A discovery about pyramidal neurons in the CA3 area of the hippocampus could help researchers develop new treatments for Alzheimer's disease and other age related memory loss problems.
Researchers shed new light on how DHA, a key essential Omega-3 fatty acid, could help promote cell survival and contribute to treating Alzheimer's, Parkinson's disease and stoke.
Study reveals the hippocampus may overlay existing mental maps with information about reward and hazard derived from food found in specific locations.
