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.

Intensive physical exercise session improves memory

If sport is good for the body, it also seems to be good for the brain. By evaluating memory performance following a sport session, neuroscientists from the University of Geneva demonstrate that an intensive physical exercise session as short as 15 minutes improves memory, including the acquisition of new motor skills.

Genetic risk factor for late-onset Alzheimer's disease has early effects on the brain

A genetic predisposition to late-onset Alzheimer's disease affects how the brains of young adults cope with certain memory tasks.

Study shows how inhibitory learning enables memories to be stable over time

In years to come, our personal memories of the COVID-19 pandemic are likely to be etched in our minds with precision and clarity, distinct from other memories of 2020.

Magnetic resonance elastography can improve the detection of epilepsy

A new study uses magnetic resonance elastography to compare the stiffness of the hippocampus in patients who have epilepsy with healthy individuals. The technique can improve the detection and characterization of the disease.

Study examines the brain's reactions in conditions of uncertainty

A new Tel Aviv University study examined the brain's reactions in conditions of uncertainty and stressful conflict in an environment of risks and opportunities.

Brain protein associated with seizures and abnormal social behaviors

A team led by a biomedical scientist at the University of California, Riverside has found a new mechanism responsible for the abnormal development of neuronal connections in the mouse brain that leads to seizures and abnormal social behaviors.

Researchers elucidate mechanisms underlying spatial memory impairment in Alzheimer's

Alzheimer's disease is one of the most serious diseases in an aging society, yet the cause is often unclear and there is no appropriate treatment method.

Study elucidates brain circuit mechanism that causes spatial memory impairment in Alzheimer's disease

Alzheimer's disease is one of the most serious diseases in an aging society, yet the cause is often unclear and there is no appropriate treatment method.

Retrieving memories is an active process that can bias and distort memories

Adopting a third-person, observer point of view when recalling your past activates different parts of your brain than recalling a memory seen through your own eyes, according to a new paper.

Study: Lower socioeconomic status is associated with reduced size of anterior hippocampus

A new study by a team of researchers from the University of Toronto (U of T) has identified the region of the brain's hippocampus that links low income with decreased memory and language ability in children.

Scientists win grant to study brain's role in tracking odors

Seeking to unravel the mystery of how animals follow scent, a team of scientists from the University of Colorado Anschutz Medical Campus, the University of Colorado Boulder and Columbia University, have won a grant to peer deeply inside the brain as the process takes place.

Brain activity in older adults is not necessarily quieter when it comes to memory

Everyone has heard it, and decades of research studies seem to confirm it: While it may not always be the first sign of aging, some faculties, including memory, do get worse as people age.

Researchers reveal molecular workings of a key system in learning and memory formation

One of the new realities in biomedical research is that it's increasingly difficult to use a general approach to score advances. Now, investigations into disease mechanisms, for example, are often conducted at the molecular level by specialists who dedicate years to interrogating a single protein or signaling pathway.

Anxiety and depression coexisting could cause physical changes to the brain

A new study from the researchers at the Australian National University shows that there may be physical changes in the brain volume among persons who have coexisting and anxiety and depressive disorders.

WVU RNI expands pioneering treatment for Alzheimer’s to open the blood-brain barrier

A hospital nurse for 33 years, Nanette Miller would call her husband Frank at the end of each shift to let him know she was coming home. On Dec. 7, 2018, the phone call came with a somber declaration: "I can't do this anymore."

Body weight seriously impacts brain activity and blood flow

As a person's weight goes up, all regions of the brain go down in activity and blood flow, according to a new brain imaging study in the Journal of Alzheimer's Disease.

New method reveals the dynamics of cell development and gene activity

Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions - but they do this with static snapshots only rather than time-lapse films.

Dream "hacking" with a novel device

A new study from American researchers shows that if dreams can be manipulated, memory could be enhanced and consolidated. The team tried a process called "dream incubation" using a device called Dormio in subjects for their study and published their novel findings.

Mice born with Fragile X syndrome have fewer cell antennas

Structures called primary cilia - which act like TV antennas for cells to detect signals - are present in fewer numbers in mice born with Fragile X syndrome, according to researchers from The University of Texas Health Science Center at San Antonio.
