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.

Mice who have partial deficiency of gene SENP2 are more likely to develop seizures, sudden death

A gene crucial for brain and heart development may also be associated with sudden unexplained death in epilepsy (SUDEP), the most common cause of early mortality in epilepsy patients.

Finding could lead researchers to better understand development of psychiatric disorders

Some people take stress in stride; others are done in by it. New research at Rockefeller University has identified the molecular mechanisms of this so-called stress gap in mice with very similar genetic backgrounds - a finding that could lead researchers to better understand the development of psychiatric disorders such as anxiety and depression.

Study for better understanding of neural circuitry and dynamic mechanisms controlling memory

A study just published in the prestigious Nature Neuroscience journal by, Sylvain Williams, PhD, and his team, of the Research Centre of the Douglas Mental Health University Institute and McGill University, opens the door towards better understanding of the neural circuitry and dynamic mechanisms controlling memory as well of the role of an essential element of the hippocampus - a sub-region named the subiculum.

Neuroscientists explore how imagination happens in the brain

Stefania Ashby and her faculty mentor devised experiments using MRI technology that would help them distinguish pure imagination from related processes like remembering.

Scientists alter emotional associations of specific memories

By manipulating neural circuits in the brain of mice, scientists have altered the emotional associations of specific memories.

Study to explain how brain reorganizes itself as children learn math facts

As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why.

Individual’s genetic make-up determines effect of stress on emotional centres

Our individual genetic make-up determines the effect that stress has on our emotional centres. These are the findings of a group of researchers from the MedUni Vienna. Not every individual reacts in the same way to life events that produce the same degree of stress.

Study suggests autophagy is involved in the onset of vascular dementia

Autophagy is a basic catabolic mechanism by which unnecessary or dysfunctional cellular components are degraded by lysosomes.

7.0T NMR spectroscopy detects lesions in hippocampal neurons of Alzheimer's disease

Magnetic resonance spectroscopy can quantitatively analyze in vivo abnormalities of biochemical metabolism within brain tissue in a noninvasive and non-radioactive manner.

UC Davis researcher receives NSSEFF grant to advance new work on learning and memory

Professor Charan Ranganath of the UC Davis Center for Neuroscience and Department of Psychology has received a National Security Science and Engineering Faculty Fellowship from the U.S. Department of Defense.

Researchers find differences in brain wiring between children with SPD and those with autism

Researchers at UC San Francisco have found that children with sensory processing disorders have decreased structural brain connections in specific sensory regions different than those in autism, further establishing SPD as a clinically important neurodevelopmental disorder.

Study provides potential drug targets for transient cerebral ischemia-reperfusion injury

Mitochondria play an important role in neuronal apoptosis caused by cerebral ischemia. Researchers at the Affiliated Hospital of Qingdao University, China discovered transient ischemia led to cell apoptosis in the hippocampus and changes in memory and cognition of aged rats.

Neuroscientists shed new light on how the brain works

Neuroscientists in Bonn and Heidelberg have succeeded in providing new insights into how the brain works. Researchers at the DZNE and the German Cancer Research Center analyzed tissue samples from mice to identify how two specific proteins, ‘CKAMP44’ and ‘TARP Gamma-8’, act upon the brain’s memory center.

New therapeutic interventions that target brain regions can prevent obesity

Unlocking the secrets to better treating the pernicious disorders of obesity and dementia reside in the brain, according to a paper from American University's Center for Behavioral Neuroscience.

Research leads to better understanding of neurodegenerative, neurodevelopmental diseases

Throughout our lives, our brains adapt to what we learn and memorise. The brain is indeed made up of complex networks of neurons and synapses that are constantly re-configured.

Drug paraphernalia triggers reward areas of brain differently in marijuana users

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users.

Study reveals way to alleviate memory deficits for Alzheimer's disease patients

A new study from the Gladstone Institutes has revealed a way to alleviate the learning and memory deficits caused by apoE4, the most important genetic risk factor for Alzheimer's disease, improving cognition to normal levels in aged mice.

Marginal division of striatum plays similar function in learning and memory to hippocampus

In addition to the hippocampus, the marginal division of the striatum is also involved in learning and memory.

New data on possible protective behaviors and dementia risk factors emerges at AAIC- 2014

Participation in activities that promote mental activity, and moderate physical activity in middle age, may help protect against the development of Alzheimer's disease and dementia in later life, according to new research reported today at the Alzheimer's Association International Conference- 2014 (AAIC- 2014) in Copenhagen.
