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.

Early life experiences produce selective maturation of learning and memory abilities

Experiences early in life have an impact on the brain's biological and functional development, shows a new study by a team of neuroscientists.

Study provides insight into how CBD influences the brains of people with psychosis

Published in Psychological Medicine, the research used fMRI scans to examine the brain activity of 13 people with a diagnosis of psychosis under the influence of a single dose of CBD or placebo and 16 controls whilst they were undertaking a memory task.

Non-invasive electrostimulation of the vagus nerve improves memory in mice

Researchers at UPF are testing a new non-invasive method of stimulating the vagus nerve in mice that improves their memory.

The influence of neuroanatomy on treatment response of patients with trigeminal neuralgia

A new study published in the journal Cephalalgia, the official journal of the International Headache Society, shows unprecedented data regarding the neuroanatomical influence on the treatment response of patients with trigeminal neuralgia.

Hot flashes associated with decreased verbal memory

If you're having difficulty identifying the right word to express yourself clearly or remembering a story correctly, you may blame menopause.

Targeted transcranial electrical stimulation can improve metamemories

HRL Laboratories, LLC, researchers have published results showing that targeted transcranial electrical stimulation during slow-wave sleep can improve metamemories of specific episodes by nearly 20% after only one viewing of the episode, compared to controls. Metamemory describes the sensitivity of whether memories are recalled accurately or not, such as during eyewitness testimony.

Maternal stress affects fetal brain development

A new study published online January 13, 2020, in the journal JAMA Pediatrics reports that mothers who suffer severe mental stress during pregnancy may have babies with abnormal development in important areas of the brain even before birth. It is already known that babies with congenital heart disease show abnormalities in brain growth and brain biochemical reactions.

Neuroimaging study reveals structural changes in the brain of migraine patients

A neuroimaging study recently published in the journal Cephalalgia, the official journal of the International Headache Society, shared more evidence of structural changes in the brain of migraine patients.

Boosting the number of neurons improves learning and memory of old mice

We all will experience it at some point, unfortunately: The older we get the more our brains will find it difficult to learn and remember new things.

Poor early life environment leaves permanent mark on adult brain

A severely deprived child may never really recover from the impact of deprivation early in life, finds a new study.

Study shows the feasibility of using gene therapy to treat chronic traumatic encephalopathy

A new study shows the feasibility of using gene therapy to treat the progressive neurodegenerative disorder chronic traumatic encephalopathy.

Exercise and a healthy lifestyle shown to reduce the risk of dementia

Research suggests that regular exercise not only improves heart health but can also slow down cognitive decline and potentially delay the onset of dementia.

Evidence for engrams as neural basis for memory

Though scientist Richard Semon introduced the concept of the "engram" 115 years ago to posit a neural basis for memory, direct evidence for engrams has only begun to accumulate recently as sophisticated technologies and methods have become available.

Obj-SCD predicts future amyloid accumulation and neurodegeneration

Writing in the December 30, 2019 online issue of Neurology, researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System report that accumulating amyloid -- an abnormal protein linked to neurodegenerative conditions such as Alzheimer's disease -- occurred faster among persons deemed to have "objectively-defined subtle cognitive difficulties" (Obj-SCD) than among persons considered to be "cognitively normal."

Amyloid plaques may not necessarily come first in Alzheimer's disease, suggests new study

The scientific community has long believed that beta-amyloid, a protein that can clump together and form sticky plaques in the brain, is the first sign of Alzheimer's disease. Beta-amyloid then leads to other brain changes including neurodegeneration and eventually to thinking and memory problems. But a new study challenges that theory.

Study measures brain injury from boxing, MMA in younger and older fighters

For boxers and mixed martial arts (MMA) fighters, is there a safe level of exposure to head trauma? A new study shows different effects in the brain for younger, current fighters compared to older, retired fighters.

Forgetful? Look at the time

An interesting new paper describes the discovery of a gene in mice that affects the degree of memory recall at various times of day. They found that this gene makes mice most forgetful at the time immediately before they wake.

Researchers identify first gene in mice specific to memory retrieval

Can't remember something? Try waiting until later in the day. Researchers identified a gene in mice that seems to influence memory recall at different times of day and tracked how it causes mice to be more forgetful just before they normally wake up.

High fat diet limits birth and development of new neurons in female mice

A high fat diet limits the birth and growth of new neurons in adult female, but not male, mice, according to new research published in eNeuro. Further research could inspire metabolism-based preventions and treatments for brain disorders.

Radiation-induced brain damage: new study reveals the mechanism

Following radiation therapy to the head for brain tumors, more than 80% of patients who live six months at least after the treatment report a loss of some cognitive functions such as memory, thinking and related tasks. Now a new study published in the journal Scientific Reports shows why this happens, which in turn could pave the way to correct this damage and protect the brain in future patients.
