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.

Size of hippocampus may be linked to early dementia

The size of the part of the brain known as the hippocampus may be linked to future dementia, reveals a thesis from the University of Gothenburg, Sweden.

Researchers find structural deficits in gray matter may be associated with daytime sleepiness

Patients with obstructive sleep apnea (OSA) may blame their daytime difficulties on simple sleepiness, but new research suggests that their brains may be to blame. Specifically, their cognitive challenges may be caused by structural deficits in gray matter, brought on by the intermittent oxygen deprivation that comes with OSA. The good news is that these deficits may be partially or fully reversible with early detection and treatment, according to Italian researchers

Early interference in entorhinal cortex may halt progression of Alzheimer's disease

New research is helping to unravel the events that underlie the "spread" of Alzheimer's disease (AD) throughout the brain. The research, published by Cell Press in the November 4th issue of the journal Neuron, follows disease progression from a vulnerable brain region that is affected early in the disease to interconnected brain regions that are affected in later stages. The findings may contribute to design of therapeutic interventions as targeting the brain region where AD originates would be simpler than targeting multiple brain areas.

Scientists identify events that causes AD progression

Scientists at the Gladstone Institute of Neurological Disease (GIND) have offered new information about the events that underlie the "spread" of Alzheimer's disease (AD) throughout the brain.

Study reveals a potential target for treating brain trauma

Brain damage continues to develop and evolve for months after a traumatic brain injury (TBI), revealing a potential target for treatments to improve brain trauma, new research led by the University of Melbourne, Australia has found.

Molecular imaging technique pinpoints changes that take place in injured brain

Results from a study published in the November issue of The Journal of Nuclear Medicine (JNM) show that powerful imaging techniques positron emission tomography (PET) fused with magnetic resonance imaging (MRI) are helping researchers better understand the long-term functional and structural changes that take place after traumatic brain injury (TBI).

Intellect obtains initial draft report of OXIGON Phase 1b clinical trial for Alzheimer’s disease

Intellect Neurosciences, Inc. a biopharmaceutical company with an internal preclinical and clinical-stage pipeline and licenses with major pharmaceutical companies covering products in late-stage clinical trials, announced that it has obtained an initial draft report of the Company's Phase 1b clinical trial for its lead Alzheimer's candidate, OXIGON (OX1).

Colour of light influences the way brain processes emotional stimuli

Researchers at the Cyclotron Research Centre (University of Liege), Geneva Center for Neuroscience and Swiss Center for Affective Sciences (University of Geneva), and Surrey Sleep Research Centre (University of Surrey) investigated the immediate effect of light, and of its color composition, on emotion brain processing using functional magnetic resonance imaging. The results of their study show that the colour of light influences the way the brain processes emotional stimuli.

ApoE4 protein causes GABAergic interneuron loss, learning and memory deficits

Alzheimer's disease (AD) is an extremely complicated disease. Several proteins seem to be involved in its cause and progression. For example, the lipid-transport protein apolipoprotein E4 (apoE4) is the major genetic risk factor for AD, and apoE4 carriers account for 65% of all Alzheimer's cases, but exactly how apoE4 contributes to the disease is unclear.

Plant compound luteolin reduces age-associated inflammation in brain leading to better cognitive health

A diet rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits by directly inhibiting the release of inflammatory molecules in the brain, researchers report.

Patients with memory impairment have intact ability to hold information in mind: Research

Researchers at the University of California, San Diego School of Medicine, led by Larry R. Squire, PhD, professor of psychiatry, psychology and neurosciences at UC San Diego and a scientist at the VA San Diego Healthcare System, report that working memory of relational information where an object is located, for example remains intact even if key brain structures like the hippocampus are damaged.

Adeona completes enrollment in Part 2 CopperProof-2 clinical study

Adeona Pharmaceuticals, Inc., announced completion of 100% enrollment in Part 2 of its clinical study, A Prospective, Randomized, Double Blind Trial of a Novel Oral Zinc Cysteine Preparation in Alzheimer's Disease (CopperProof-2).

New hope for patients with brain injury

New neuroscience research by life scientists from UCLA and Australia may potentially help people who have lost their ability to remember due to brain injury or disease.

Second pathway to brain’s memory function uncovered

Australian and US scientists have successfully identified a new mechanism by which the brain learns and stores memories. This could spell hope for brain injuries and diseases like Alzheimer’s disease.

Study indicates neurotransmitters are abnormal in people with psychotic illness

There is growing evidence that two neurotransmitters - dopamine and glutamate - are abnormal in people with psychotic illness, including schizophrenia. Among many other things, these chemicals play a role in cognitive functions, such as memory, learning, and problem-solving.

New approach to prevent psychotic symptoms

New research has linked psychosis with an abnormal relationship between two signalling chemicals in the brain. The findings, published in tomorrow's edition of the journal Biological Psychiatry, suggest a new approach to preventing psychotic symptoms, which could lead to better drugs for schizophrenia.

Study suggests drugs targeting glutamatergic transmission may help treat psychotic illness

There is growing evidence that two neurotransmitters dopamine and glutamate are abnormal in people with psychotic illness, including schizophrenia. Among many other things, these chemicals play a role in cognitive functions, such as memory, learning, and problem solving.

Gene deletion may make you smarter: Study

A new study has shown that switching off a single gene in mice unlocks a part of their brain that is otherwise inactive, boosting learning and memory. Considering the fact that humans have a similar gene, this sparks hope for many especially those who suffer from dementia and Alzheimer’s.

Disabling RGS14 gene helps mice remember better

Deleting a certain gene in mice can make them smarter by unlocking a mysterious region of the brain considered to be relatively inflexible, scientists at Emory University School of Medicine have found.

Research on BMP6 protein suggests potential therapeutic target for Alzheimer's disease

Elevated levels of a growth protein in the brains of Alzheimer's disease (AD) patients is linked to impaired neurogenesis, the process by which new neurons are generated, say researchers at the University of California, San Diego in today's edition of The Journal of Neuroscience.
