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.

Hydrogen sulfide significantly improves survival after extreme blood loss

For the first time, researchers have demonstrated that the administration of minute amounts of inhaled or intravenous hydrogen sulfide, or H2S - the molecule that gives rotten eggs their sulfurous stench - significantly improves survival from extreme blood loss in rats.

Protein Ronin shown to be an alternate control for embryonic stem cells

Like the masterless samurai for whom it is named, the protein Ronin chooses an independent path, maintaining embryonic stem cells in their undifferentiated state and playing essential roles in genesis of embryos and their development, said Baylor College of Medicine researchers who reported on this novel cellular regulator in the current issue of the journal Cell.

Seniors with type 2 diabetes may experience memory declines immediately after eating unhealthy meal

Adults with type 2 diabetes who eat unhealthy, high-fat meals may experience memory declines immediately afterward, but this can be offset by taking antioxidant vitamins with the meal, according to new research from Baycrest.

Discovery of second genetic risk factor for developing late-onset Alzheimer's disease

Researchers have discovered the second, strong genetic risk factor for developing late-onset Alzheimer's disease, according to a new report in the June 27th issue of the journal Cell, a Cell Press publication.

Study uncovers how Ritalin works in brain to boost cognition, focus attention

Stimulant medications such as Ritalin have been prescribed for decades to treat attention deficit hyperactivity disorder (ADHD), and their popularity as "cognition enhancers" has recently surged among the healthy, as well.

Automated magnetic resonance imaging technique assists in earlier Alzheimer's diagnosis

An automated system for measuring brain tissue with magnetic resonance imaging (MRI) can help physicians more accurately diagnose Alzheimer's disease at an earlier stage according to a new study published in the July issue of the journal Radiology.

Researchers create molecule that nudges nerve stem cells to mature

Inspired by a chance discovery during another experiment, researchers at UT Southwestern Medical Center have created a small molecule that stimulates nerve stem cells to begin maturing into nerve cells in culture.

Drug rapamycin reverses mental retardation caused by tuberous sclerosis complex

UCLA researchers discovered that an FDA-approved drug reverses the brain dysfunction inflicted by a genetic disease called tuberous sclerosis complex (TSC). Because half of TSC patients also suffer from autism, the findings offer new hope for addressing learning disorders due to autism. Nature Medicine publishes the findings in its online June 22 edition.

Long term dope use shrinks the brain

According to Australian researchers the long term use of marijuana may cause parts of the brain which control memory, emotion and aggression, to shrink.

Long-term, heavy cannabis use may shrink brain's hippocampus and amygdala

Long-term, heavy cannabis use may be associated with structural abnormalities in areas of the brain known as the hippocampus and amygdala, according to a report in the June issue of Archives of General Psychiatry.

Plant flavonoid luteolin reduces inflammatory response in the brain

Researchers at the University of Illinois report this week that a plant compound found in abundance in celery and green peppers can disrupt a key component of the inflammatory response in the brain. The findings have implications for research on aging and diseases such as Alzheimer's and multiple sclerosis.

Big differences in depressed brains

Depressed people may have far fewer of the receptors for some of the brain's "feel good" stress-response chemicals than non-depressed people, new University of Michigan Depression Center research shows.

New discovery on how memory is stored

Researchers at Wake Forest University School of Medicine are the first to show that the location of protein-destroying "machines" in nerve cells in the brain may play an important role in how memories are formed - a finding with potential implications for treating Alzheimer's and other brain diseases. The research is published in the current issue of Learning & Memory.

Constraint induced therapy causes increase in gray matter

A rehabilitation therapy developed by a UAB (University of Alabama at Birmingham) neuroscientist produces changes in the structure of the brain, the first evidence of actual brain remodeling resulting from a rehabilitation therapy.

Methamphetamine use in pregnancy changes learning ability of the offspring

Studies have suggested that infants exposed to methamphetamines while in the womb can suffer irreversible brain damage, although the exact effects of these drugs during pregnancy have been hard to pinpoint due to many other negative behaviors that often occur in meth users.

Diabetes drug may hold potential as treatment for epilepsy, using same mechanism as ketogenic diet

Two years ago, University of Wisconsin-Madison scientists reported they had suppressed epileptic seizures in rats by giving them a glycolytic-inhibitor, inhibiting the brain's ability to turn sugar into excess energy and blocking the expression of seizure-related genes.
