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.

The brain uses an alarm system to suppress unwanted memories

Forget what you saw: a brain region detects when you are about to think of an unwanted memory and alerts other regions to suppress it, according to research recently published in JNeurosci.

Study suggests severe neuroinvasion by SARS-CoV-2 in individuals with alcohol use disorder

Researchers investigated the effect of repeated alcohol exposure and withdrawal on angiotensin-converting enzyme 2 and transmembrane serine protease 2 expression, putative regulators of SARS-CoV-2 entry, in discrete brain regions.

Virtual reality test could offer a promising way of effectively assessing functional cognition in adults

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London suggests that a virtual reality test in which participants "go to the shops" could offer a potentially promising way of effectively assessing functional cognition, the thinking and processing skills needed to accomplish complex everyday activities

Researchers discover a compound that reduces epileptic seizures

Researchers studying epileptic seizures of the temporal lobe – the most common type of epilepsy – discovered a compound that reduces seizures in the hippocampus, a brain region where many such seizures originate.

TTUHSC secures $1.87 million grant to investigate the impact of vitamin A depletion on Alzheimer’s disease

Ongoing research suggests that an accumulation of toxic reactive oxygen species (ROS) in the area of the brain known as the hippocampal dentate gyrus may begin early on in patients with Alzheimer's disease.

Study provides new understanding of how memory works when the brain sees a familiar face

In a study led by Cedars-Sinai, researchers have uncovered new information about how the area of the brain responsible for memory is triggered when the eyes come to rest on a face versus another object or image.

Research uncovers how memories and fear-responses can be transmitted through social interactions

Has a song ever reminded you of the past, and unexpectedly surfaced emotions associated with that specific experience or person from your memory? Does walking into Staples remind you of back-to-school shopping, even years after graduating?

Researchers find turbocharger for memory in the brain cells of mice

Scientists have long known that learning requires the flow of calcium into and out of brain cells. But researchers at Columbia's Zuckerman Institute have now discovered that floods of calcium originating from within neurons can also boost learning.

COVID-19 may cause brain shrinkage in some people

In a recent study posted to the journal Nature as an unedited manuscript, researchers assessed the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated brain changes among United Kingdom (UK) Biobank patients.

Novel MRI approach can identify brain cell damage in people at early stages of Alzheimer's

Alzheimer's disease usually is diagnosed based on symptoms, such as when a person shows signs of memory loss and difficulty thinking.

Study unravels why women are more susceptible to Alzheimer’s disease

Epidemiological studies have shown that women are twice as likely as men to develop Alzheimer's disease (AD), but the cause of this phenomenon has been unclear.

2 Mar 2022

New insights into why women develop Alzheimer's symptoms earlier and exhibit faster memory decline

A joint study by Nanyang Technological University, Singapore and National University of Singapore (NUS) scientists has examined why, in mice, female brains are more predisposed to Alzheimer's disease and other neurodegenerative diseases.

Progression of Alzheimer's disease is linked to oxidative brain damage, research confirms

Increased oxidative damage is linked to neurodegenerative disorders such as Alzheimer's disease (AD). Even though the pathophysiology of AD has been widely investigated, the likely relationship between mitochondrial dysfunction and the disease remains largely unknown.

Scientific statement highlights the uncertainty about health effects of marijuana

Despite the perception that marijuana is harmless, there is some scientific evidence challenging that belief, and there are many unanswered questions about its impact on brain health, according to a new American Heart Association scientific statement published today in the Association's journal Stroke.
