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.

Research focuses on DYRK1A gene in association with Down's syndrome

Research undertaken in recent years on Down's syndrome has focused on the DYRK1A gene. The superexpression of this gene affects transmission in the neurones, according to Mr Garikoitz Azkona. In his PhD thesis, The molecular bases of neuropathology in Down's syndrome: the role of DYRK1A, Mr Azkona argues that this failure in neurone transmission could be behind the problem that persons with Down's syndrome have regarding visual-spatial memory.

Neurogenesis linked to drug addiction and relapse

Researchers at UT Southwestern Medical Center hope they have begun paving a new pathway in the fight against drug dependence. Their hypothesis - that increasing the normally occurring process of making nerve cells might prevent addiction - is based on a rodent study demonstrating that blocking new growth of specific brain nerve cells increases vulnerability for cocaine addiction and relapse.

Neural differences in map of the brain when learning new nouns and verbs

Two Spanish psychologists and a German neurologist have recently shown that the brain that activates when a person learns a new noun is different from the part used when a verb is learnt. The scientists observed this using brain images taken using functional magnetic resonance, according to an article they have published this month in the journal Neuroimage.

Siestas can dramatically boost and restore brain power

If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don't roll your eyes. New research from the University of California, Berkeley, shows that an hour's nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.

VTT Technical Research Centre develops 3-minute MR image assessment method

VTT Technical Research Centre of Finland has developed a method for analysing MR images in just a few minutes when diagnosing Alzheimer's disease. The accuracy of the analysis is comparable to manual measurements made by skilled professionals, which are currently considered the most reliable method for diagnosing Alzheimer's disease. The accurate and rapid analysis method is well suited for clinical use.

Brain researchers explore link between emotion and memory

In a novel study that used historical tape of a thrilling overtime basketball game between Duke and the University of North Carolina at Chapel Hill, brain researchers at Duke have found that fans remember the good things their team did much better than the bad.

Gene linked to PMDD and other maladies during menstrual cycle

Scientists have identified a gene they say is a strong candidate for involvement in premenstrual dysphoric disorder (PMDD) and other maladies associated with the natural flux in hormones during the menstrual cycle. In a paper to be published today in the Proceedings of the National Academy of Sciences, Rockefeller University researchers detail experiments in mice showing that a common human variant of the gene increases anxiety, dampens curiosity and tweaks the effects of estrogen on the brain, impairing memory.

Evidence suggests antidepressants may improve post-stroke recovery

Patients who received the antidepressant escitalopram following a stroke appeared to recover more of their thinking, learning and memory skills than those taking placebo or participating in problem-solving therapy, according to a report in the February issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Study: Schizophrenia patients may experience beneficial brain changes in response to exercise

Potentially beneficial brain changes (an increase in the volume of an area known as the hippocampus) occur in response to exercise both in patients with schizophrenia and healthy controls, according to a report in the February issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Researchers use sophisticated brain-imaging techniques to predict Alzheimer's before symptoms appear

Estimates are that some 10 percent of people over the age of 65 will develop Alzheimer's disease, the scourge that robs people of their memories and, ultimately, their lives.

UCLA researchers predict brain's progression to Alzheimer's before symptoms are visible

Estimates are that some 10 percent of people over the age of 65 will develop Alzheimer's disease, the scourge that robs people of their memories and, ultimately, their lives.

New Tel Aviv University study shows early intervention could prevent mind altering disorder

The onset of schizophrenia is not easy to predict. Although it is associated with as many as 14 genes in the human genome, the prior presence of schizophrenia in the family is not enough to determine whether one will succumb to the mind-altering condition. The disease also has a significant environmental link.

Florida State University research team to develop way of measuring zinc levels in the human body

A team of Florida State University researchers will use a five-year, $1.3 million grant from the National Institutes of Health to develop a way to measure levels of the trace metal zinc in the human body.

Discovery could help improve diagnosis and treatment for anxiety disorders

Draw a map of the brain when fear and anxiety are involved, and the amygdala-the brain's almond-shaped center for panic and fight-or-flight responses-looms large.

Chronic insomnia may be associated with reduced cortical volume, says study

Chronic and severely stressful situations, like those connected to depression and posttraumatic stress disorder, have been associated with smaller volumes in "stress sensitive" brain regions, such as the cingulate region of the cerebral cortex and the hippocampus, a brain region involved in memory formation.

Geron collaborates to explore hESC-based product for Alzheimer’s disease

Geron Corporation today announced that it has entered into a collaboration jointly funded by Geron and a University of California Discovery Research and Training Grant to investigate the therapeutic potential of its human embryonic stem cell (hESC)-based product, GRNOPC1, for Alzheimer’s disease. The company is currently developing GRNOPC1 for the potential treatment of spinal cord injury.

Study demonstrates BTG2 gene is crucial for neurogenesis and contextual memory function

The birth of new neurons, a process called neurogenesis, is continuously occurring in the brain, not only during development but also during adulthood within two specialized areas, the hippocampus and the subventricular zone.

Tocotrienol form of vitamin E prevents neural cell death and rescues the brain after stroke injury

Blocking the function of an enzyme in the brain with a specific kind of vitamin E can prevent nerve cells from dying after a stroke, new research suggests.

New genetic findings may lead to better interventional therapies for obsessive compulsive disorders

A collaboration between the University of Massachusetts Medical School, the Cummings School of Veterinary Medicine at Tufts University and the Broad Institute at the Massachusetts Institute of Technology has identified a genetic locus on canine chromosome 7 which coincides with an increased risk of obsessive compulsive disorder (OCD) susceptibility.

Diffusion tensor imaging detects signs of Alzheimer's disease

A new type of brain scan, called diffusion tensor imaging (DTI), appears to be better at detecting whether a person with memory loss might have brain changes of Alzheimer's disease, according to a new study published in the January 6, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.
