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

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]
Neuroscientists discover key building block for learning and memory formation

Neuroscientists discover key building block for learning and memory formation

Researchers have been fascinated for a long time by learning and memory formation, and many questions are still open. Bochum-based neuroscientists Prof Dr Denise Manahan-Vaughan and Dr Hardy Hagena have discovered a key building block for this complex process. [More]
Researchers present new studies on cognition and reasoning at CNS conference in San Francisco

Researchers present new studies on cognition and reasoning at CNS conference in San Francisco

Even rats can imagine: A new study finds that rats have the ability to link cause and effect such that they can expect, or imagine, something happening even if it isn't. [More]
UCLA-led team validates first standardized protocol for tracking early signs of Alzheimer's disease

UCLA-led team validates first standardized protocol for tracking early signs of Alzheimer's disease

After six years of painstaking research, a UCLA-led team has validated the first standardized protocol for measuring one of the earliest signs of Alzheimer's disease -- the atrophy of the part of the brain known as the hippocampus. [More]
Study: Progression of dysfunctional tau protein drives cognitive decline in Alzheimer's disease

Study: Progression of dysfunctional tau protein drives cognitive decline in Alzheimer's disease

By examining more than 3,600 postmortem brains, researchers at Mayo Clinic's campuses in Jacksonville, Florida, and Rochester, Minnesota, have found that the progression of dysfunctional tau protein drives the cognitive decline and memory loss seen in Alzheimer's disease. [More]
Brief sleep can significantly improve memory performance

Brief sleep can significantly improve memory performance

Generations of school students have gone to bed the night before a maths exam or a vocabulary test with their algebra book or vocabulary notes tucked under their pillow in the hope that the knowledge would somehow be magically transferred into their brains while they slept. [More]
Hypermethylation serves as protective barrier inhibiting development of ALS, FTD

Hypermethylation serves as protective barrier inhibiting development of ALS, FTD

Penn Medicine researchers have discovered that hypermethylation - the epigenetic ability to turn down or turn off a bad gene implicated in 10 to 30 percent of patients with Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Degeneration (FTD) - serves as a protective barrier inhibiting the development of these diseases.

Cannabis abuse affects long-term memory, finds new Northwestern Medicine study

Cannabis abuse affects long-term memory, finds new Northwestern Medicine study

Teens who were heavy marijuana users - smoking it daily for about three years -- had an abnormally shaped hippocampus and performed poorly on long-term memory tasks, reports a new Northwestern Medicine study. [More]
Existing epilepsy drug reverses aMCI in elderly patients at risk for Alzheimer's disease

Existing epilepsy drug reverses aMCI in elderly patients at risk for Alzheimer's disease

A novel therapeutic approach for an existing drug reverses a condition in elderly patients who are at high risk for dementia due to Alzheimer's disease, researchers at Johns Hopkins University found. [More]
Rat study reveals role of lead in schizophrenia

Rat study reveals role of lead in schizophrenia

A study of the brains of rats exposed to lead has uncovered striking similarities with what is known about the brains of human schizophrenia patients, adding compelling evidence that lead is a factor in the onset of schizophrenia. [More]
McGill researchers discover key epigenetic factor that controls development of hippocampus

McGill researchers discover key epigenetic factor that controls development of hippocampus

McGill researchers have discovered, for the first time, the importance of a key epigenetic regulator in the development of the hippocampus, a part of the brain associated with learning, memory and neural stem cells. [More]
Common antidepressant medications not helpful for people with mood, anxiety disorders

Common antidepressant medications not helpful for people with mood, anxiety disorders

Studies indicate that the majority of people with mood and anxiety disorders who receive the most commonly prescribed class of antidepressant medications, Selective Serotonin Reuptake Inhibitors or SSRI's, are not helped by these medications. SSRIs are designed to increase serotonin, a neurotransmitter in the brain that is key to maintenance of mood. [More]
Anxiety and déjà vu: an interview with Dr Christine Wells, Sheffield Hallam University

Anxiety and déjà vu: an interview with Dr Christine Wells, Sheffield Hallam University

It’s thought that the neural basis of déjà vu is located in the temporal lobes, a region of the brain strongly associated with the storage and retrieval of memories. One source of support for this is evidence from individuals with temporal lobe epilepsy, some of whom experience déjà vu episodes as part of seizure-related auras... [More]

New study challenges scientific theory about role of hippocampus in unconscious memory

A new study by a UT Dallas researcher challenges a long-accepted scientific theory about the role the hippocampus plays in our unconscious memory. [More]
Scientists show pattern of connectivity in newly-generated hippocampal neurons

Scientists show pattern of connectivity in newly-generated hippocampal neurons

Research by a team of scientists from Cologne, Munich and Mainz has shown an unprecedented degree of connectivity reorganization in newly-generated hippocampal neurons in response to experience, suggesting their direct contribution to the processing of complex information in the adult brain. [More]

New study heightens concerns over the detrimental impact of APOE ε4 in urban children

A new study by researchers at the Universities of Montana, Carleton, and North Carolina, and the Centro de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México, heightens concerns over the detrimental impact of the apolipoprotein E (APOE) ε4 allele -- the most prevalent genetic risk for Alzheimer's disease -- upon cognition, olfaction, and metabolic brain indices in healthy urban children and teens.
