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.

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.

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.

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.

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.

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.
