Hippocampus News and Research RSS Feed - Hippocampus News and Research

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.
New research shows surgical menopause increases cognitive decline and dementia

New research shows surgical menopause increases cognitive decline and dementia

Women who abruptly and prematurely lose estrogen from surgical menopause have a two-fold increase in cognitive decline and dementia. [More]
Salk scientists discover how brain keeps track of similar but distinct memories

Salk scientists discover how brain keeps track of similar but distinct memories

Ever find yourself racking your brain on a Monday morning to remember where you put your car keys? When you do find those keys, you can thank the hippocampus, a brain region responsible for storing and retrieving memories of different environments-such as that room where your keys were hiding in an unusual spot.

Mayo Clinic neurology experts present research findings at AAN meeting

Mayo Clinic neurology experts will present research findings on Parkinson's disease, Alzheimer's disease, sleep disorders, concussions, multiple sclerosis and more at the American Academy of Neurology annual meeting in San Diego, March 16-23. [More]
Autism spectrum disorders affect brain activity of children and adults differently

Autism spectrum disorders affect brain activity of children and adults differently

Newly released findings from Bradley Hospital published in the Journal of the American Academy of Child & Adolescent Psychiatry have found that autism spectrum disorders (ASD) affect the brain activity of children and adults differently. [More]
Research findings could lead to new sleep therapies to improve memory disorders

Research findings could lead to new sleep therapies to improve memory disorders

A team of sleep researchers led by UC Riverside psychologist Sara C. Mednick has confirmed the mechanism that enables the brain to consolidate memory and found that a commonly prescribed sleep aid enhances the process. [More]
CALHM1 channel protein releases ATP to make neural taste connections

CALHM1 channel protein releases ATP to make neural taste connections

Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now. [More]

Research illuminates why stimulating environment may protect against Alzheimer's disease

"Use it or lose it." The saying could apply especially to the brain when it comes to protecting against Alzheimer's disease. [More]

mTORC2 plays key role in regulating memory formation

Introductions at a party seemingly go in one ear and out the other. However, if you meet someone two or three times during the party, you are more likely to remember his or her name. Your brain has taken a short-term memory - the introduction - and converted it into a long-term one. [More]
Selective activation of the dentate gyrus can reduce anxiety without affecting learning

Selective activation of the dentate gyrus can reduce anxiety without affecting learning

Columbia University Medical Center (CUMC) researchers have found the first evidence that selective activation of the dentate gyrus, a portion of the hippocampus, can reduce anxiety without affecting learning. [More]
Schizophrenic people with MIR137 tend to develop illness at younger age

Schizophrenic people with MIR137 tend to develop illness at younger age

Some of the dramatic differences seen among patients with schizophrenia may be explained by a single gene that regulates a group of other schizophrenia risk genes. These findings appear in a new imaging-genetics study from the Centre for Addiction and Mental Health (CAMH). [More]
Study opens possibility for creating animal models of memory disorders

Study opens possibility for creating animal models of memory disorders

If you ask a rat whether it knows how it came to acquire a certain coveted piece of chocolate, Indiana University neuroscientists conclude, the answer is a resounding, "Yes." A study newly published in the journal Current Biology offers the first evidence of source memory in a nonhuman animal. [More]
Loss of Dickopf-1 restores neurogenesis and memory in animal model

Loss of Dickopf-1 restores neurogenesis and memory in animal model

Loss of the molecule Dickopf-1 in the hippocampus in older animals increases neurogenesis, research shows. [More]
Harmful effects of stress may be key to managing chronic pain

Harmful effects of stress may be key to managing chronic pain

For chronic pain sufferers, such as people who develop back pain after a car accident, avoiding the harmful effects of stress may be key to managing their condition. [More]

New research offers clues for chemotherapy-induced cognitive impairment

It's not unusual for cancer patients being treated with chemotherapy to complain about not being able to think clearly, connect thoughts or concentrate on daily tasks. The complaint - often referred to as chemo-brain - is common. The scientific cause, however, has been difficult to pinpoint. [More]

Tiny microscope can help scientists observe neuronal firings in the brain

If you want to read a mouse's mind, it takes some fluorescent protein and a tiny microscope implanted in the rodent's head. [More]

TSG might be novel compound for treatment of Alzheimer's and dementia with Lewy body

Administration of the active compound tetrahydroxystilbene glucoside (TSG) derived from the Chinese herbal medicine Polygonum multiflorum Thunb, reversed both overexpression of α-synuclein, a small protein found in the brain, and its accumulation using a mouse model of Alzheimer's disease. [More]
Prions may be crucial in brain development during childhood

Prions may be crucial in brain development during childhood

A molecule that is not only dangerous, but can help the brain grow. A few years ago it was found that certain proteins, the prions, when defective are dangerous, as they are involved in neurodegenerative syndromes such as the Creutzfeldt-Jakob and the Alzheimer diseases. [More]

Study demonstrates how CN2097 works to restore neural functions impaired by Angelman syndrome

In a new study in mice, a scientific collaboration centered at Brown University lays out in unprecedented detail a neurological signaling breakdown in Angelman syndrome, a disorder that affects thousands of children each year, characterized by developmental delay, seizures, and other problems.

Study finds reason why patients with chronic pain often suffer from impaired short -term memory

A group of Portuguese researchers from IBMC and FMUP at the University of Porto has found the reason why patients with chronic pain often suffer from impaired short -term memory. [More]
Location of altered brain metabolite levels found in bipolar I patients

Location of altered brain metabolite levels found in bipolar I patients

Bipolar I disorder patients have increased phospholipid levels in the thalami and increased N-acetyl-aspartate levels in the left hippocampus compared with healthy individuals, a team of investigators has discovered. [More]
