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.
Diabetes and poor diet can trigger Alzheimer's or Parkinson's, warns BUAP researcher

Diabetes and poor diet can trigger Alzheimer's or Parkinson's, warns BUAP researcher

For several years a researcher was dedicated to feed rodents in his laboratory with a high caloric content and glucose concentrations, which caused them diabetes, and by scientifically assessing what occurred in animals he observed that "diabetes and poor diet is a risk factor for developing Alzheimer's or Parkinson's," warns Samuel Treviño Mora from the Meritorious University of Puebla in Mexico.

Previous motherhood alters cognition, neuroplasticity in response to hormone therapy

Previous motherhood alters cognition, neuroplasticity in response to hormone therapy

Hormone therapy (HT) is prescribed to alleviate some of the symptoms of menopause in women. Menopausal women are more likely to be diagnosed with Alzheimer's disease but not other forms of dementia, and HT has been prescribed to treat cognitive decline in post-menopausal women with variable degrees of effectiveness.

Discovery has clear implications in the quest for new epilepsy treatments

Discovery has clear implications in the quest for new epilepsy treatments

The mission of neural stem cells located in the hippocampus, one of the main regions of the brain, is to generate new neurons during the adult life of mammals, including human beings, of course, and their function is to participate in certain types of learning and responses to anxiety and stress.

Small-molecule drug simultaneously rejuvenates old muscles, aging brains

Small-molecule drug simultaneously rejuvenates old muscles, aging brains

Whether you're brainy, brawny or both, you may someday benefit from a drug found to rejuvenate aging brain and muscle tissue. Researchers at the University of California, Berkeley, have discovered that a small-molecule drug simultaneously perks up old stem cells in the brains and muscles of mice, a finding that could lead to drug interventions for humans that would make aging tissues throughout the body act young again.

New work challenges long-held beliefs about link between hippocampus and improved memory function

New work challenges long-held beliefs about link between hippocampus and improved memory function

New work by the Douglas Mental Health University Institute (CIUSSS de l'Ouest-de-l'île-de-MontréalI) computational neuroscientist Mallar Chakravarty, PhD, and in collaboration with researchers at the Centre for Addiction and Mental Health challenges in a thrilling way the long-held belief that a larger hippocampus is directly linked to improved memory function.

Major breakthrough provides new insights into how tinnitus develops

Major breakthrough provides new insights into how tinnitus develops

Tinnitus is the most common service-related disability for veterans returning from Iraq and Afghanistan. Often described as a ringing in the ears, more than 1.5 million former service members, one out of every two combat veterans, report having this sometimes debilitating condition, resulting in more than $2 billion dollars in annual disability payments by the U.S. Department of Veterans Affairs.

New study could point to potential ways to address defects in learning, memory

New study could point to potential ways to address defects in learning, memory

Just as some people seem built to run marathons and have an easier time going for miles without tiring, others are born with a knack for memorizing things, from times tables to trivia facts. These two skills—running and memorizing—are not so different as it turns out. [More]
UV researchers study neurobiological link between ASD and epilepsy

UV researchers study neurobiological link between ASD and epilepsy

Researchers at the University of Veracruz (UV), in the west coast of Mexico, study the neurobiological link between the Autism Spectrum Disorder (ASD) and epilepsy, in order to understand the reason why the brain of an autistic child is 20-30 percent more susceptible to seizures that an infant without this condition.

Research shows that hippocampus is dedicated to memory formation, not to spatial skills

In work that reconciles two competing views of brain structures involved in memory and spatial perception, researchers at University of California, San Diego School of Medicine have conducted experiments that suggest the hippocampus - a small region in the brain's limbic system - is dedicated largely to memory formation and not to spatial skills, such as navigation.

Complete review of amyloid-beta protein behind Alzheimer's disease

"It will still take many years to understand the mechanisms leading to the formation of the characteristic plaques seen in brains affected by Alzheimer's disease", explains Alessandro Laio, SISSA professor. "We know they are mostly a build-up of amyloid-beta peptide, the protein that research is currently focusing on". And, as of today, all those involved in biomolecular research on Alzheimer's will have access to a new and important instrument: an extensive and complete review of all scientific knowledge about this "killer protein" has in fact just been published in the journal Chemical Reviews.

Blueberries may be effective in treatment for PTSD

Blueberries may be effective in treatment for PTSD

Up to 8 percent of people in the U.S. suffer from post-traumatic stress disorder (PTSD) as the result of witnessing or being the victim of a traumatic event. People with PTSD have been in a situation in which they were at risk of death, serious injury or sexual violence or have seen first-hand loved ones faces such threats. They may experience flashbacks, emotional detachment and jumpiness, among other symptoms that affect their ability to function in everyday life. [More]
