Hippocampus News and Research

RSS

The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

Depression and Alzheimer's

People who have had depression are more likely to develop Alzheimer's disease than people who have never had depression, according to a study published in the April 8, 2008, issue of Neurology®, the medical journal of the American Academy of Neurology.

Alcohol alters prefrontal cortex activity through ion channel disruption

The prefrontal cortex (PFC) region of the brain is involved in decision making. New rodent findings show that PFC neuron N-methyl-D-aspartic acid (NMDA) receptors are especially sensitive to concentrations of alcohol achieved during drinking.

Wine harder on the brain than beer

Scientists say wine damages the brain more than beer or spirits, because it particularly affects the hippocampus, the part of the brain associated with memory and spatial awareness.

Pain receptor in brain may be linked to learning and memory

Scientists have long known that the nervous system receptor known as TRPV1 can affect sensations of pain in the body.

TRPV1 receptor blockers may interfere with brain functions

A new class of painkillers that block a receptor called TRPV1 may interfere with brain functions such as learning and memory, a new study suggests.

Short-term stress impairs brain-cell communication

Short-term stress lasting as little as a few hours can impair brain-cell communication in areas associated with learning and memory, University of California, Irvine researchers have found.

Cell therapy for rejuvenating aged brain by injection of human umbilical cord blood

When human umbilical cord blood cells (UCBC) were injected into aged laboratory animals, researchers at the University of South Florida (USF) found improvements in the microenvironment of the hippocampus region of the animals' brains and a subsequent rejuvenation of neural stem/progenitor cells.

Insulin administered intranasally may lower food intake in men, improve memory in women

Insulin administered intranasally, acutely decreases food intake in men but not women and in contrast, the compound improves memory function in women but not men according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM).
