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.

Nimodipine reduces febrile seizures

Fever-induced childhood seizures, known as febrile seizures, can be terrifying for parents to witness. The full-body convulsions, which mostly affect children six months to five years old, can last from mere seconds up to more than 40 minutes. Currently, children are not treated with daily anticonvulsant medication to prevent these seizures even when they recur repeatedly because toxic side effects of existing treatments outweigh potential benefits.

Kessler Foundation receives grants from NJ Commission to study deficits in TBI patients

The New Jersey Commission on Brain Injury Research awarded two grants to scientists at Kessler Foundation to study emotional processing deficits in people with traumatic brain injury (TBI) and the effects of aerobic exercise on memory impairments after TBI. The grants exceeded $500,000.

Scientists discover how Arc protein helps translate learning into memory

Scientists at the Gladstone Institutes have deciphered how a protein called Arc regulates the activity of neurons-providing much-needed clues into the brain's ability to form long-lasting memories. These findings, reported today in Nature Neuroscience, also offer newfound understanding as to what goes on at the molecular level when this process becomes disrupted.

Researchers mobilize brain's native stem cells to replenish neuron lost in Huntington's disease

Researchers have been able to mobilize the brain's native stem cells to replenish a type of neuron lost in Huntington's disease.

New minimally invasive surgery for epilepsy offers quicker recuperation time for patients

A new minimally invasive laser-based tool for epilepsy surgery offers a quicker recuperation time for patients than major surgery, Mayo Clinic researchers report. The research is ongoing, but preliminary results were recently presented at the American Academy of Neurology.

Tel Aviv University researchers find protein modification may help control Alzheimer's and epilepsy

In the brain, cell-to-cell communication is dependent on neurotransmitters, chemicals that aid the transfer of information between neurons. Several proteins have the ability to modify the production of these chemicals by either increasing or decreasing their amount, or promoting or preventing their secretion.

GLYX-13 drug induces antidepressant results without street drug side effects

GLYX-13, a molecular cousin to ketamine, induces similar antidepressant results without the street drug side effects, reported a study funded by the National Institute of Mental Health (NIMH) that was published last month in Neuropsychopharmacology.

New MRI superresolution methods enable structural study of psychosis

A team of researchers from the UPNA/NUP-Public University of Navarre has developed new superresolution and segmentation methods for magnetic resonance images so that they can be applied to the structural study of psychosis. The aim is to be able to identify the differences that are produced in specific parts of the brain in psychotic patients with respect to their healthy relatives or other people.

Long-term depression linked with life-threatening chronic disease, earlier death

The first symptoms of major depression may be behavioral, but the common mental illness is based in biology — and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk factors have been taken into account.

Stronger epigenetic changes in estrogen responsive genes linked to postpartum depression

The epigenetic modifications, which alter the way genes function without changing the underlying DNA sequence, can apparently be detected in the blood of pregnant women during any trimester, potentially providing a simple way to foretell depression in the weeks after giving birth, and an opportunity to intervene before symptoms become debilitating.

Research shows new neural circuits arise when hippocampus is disabled

When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways - often far from the damaged site.

Findings could help develop new approaches to treat depression and memory loss in the elderly

Scientists have known for some time that exercise induces neurogenesis in a specific brain region, the hippocampus. However, until this study, the underlying mechanism was not fully understood.

Complex network of molecules controls formation and activity of neuronal connections

Environment moulds behaviour - and not just that of people in society, but also at the microscopic level. This is because, for their function, neurons are dependent on the cell environment, the so-termed extracellular matrix.

New form of electroconvulsive therapy could prevent adverse cognitive side effects

Electroconvulsive therapy (ECT) is the most effective acute treatment for severe major depression. However, even with newer forms of ECT, there remains a significant risk of adverse cognitive effects, particularly memory problems.

Discovery raises hope for severe forms of human epilepsy

Epilepsy that does not respond to drugs can be halted in adult mice by transplanting a specific type of cell into the brain, UC San Francisco researchers have discovered, raising hope that a similar treatment might work in severe forms of human epilepsy.

Virtual reality reveals new clues on how cells determine place

Leaving the house in the morning may seem simple, but with every move we make, our brains are working feverishly to create maps of the outside world that allow us to navigate and to remember where we are.

Neuralstem gets approval from FDA for dosing cohort patients in NSI-189 Phase Ib in MDD treatment

Neuralstem, Inc. announced that it has received approval from the Food and Drug Administration (FDA) to begin dosing the third and final cohort of patients in its ongoing Phase Ib to test the safety of NSI-189 in the treatment of major depressive disorder (MDD).

Schizophrenia patients misinterpret anger

A study shows that patients with schizophrenia struggle to recognize angry facial expressions, often mistaking them for fear.

CI therapy appears to benefit children with cerebral palsy

Researchers at the University of Alabama at Birmingham (UAB) report that children with cerebral palsy who underwent Constraint Induced Movement therapy (CI therapy) saw a significant increase in grey matter volume in areas of the brain associated with movement.

Study: Stem cell transplant heals neurological deficits in mice

For the first time, human embryonic stem cells have been transformed into nerve cells that helped mice regain the ability to learn and remember.
