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.

Drebrin autoantibodies trigger epilepsy

Certain forms of epilepsy are accompanied by inflammation of important brain regions. Researchers at the University of Bonn have now identified a mechanism that explains this link.

Odor alters how memories are processed in the brain, research reveals

In a new paper published in Learning and Memory, researchers from Boston University's Center for Systems Neuroscience reveal just how much power scents have in triggering the memory of past experiences--and the potential for odor to be used as a tool to treat memory-related mood disorders.

Cannabinoid 1 receptor expression displays sexually dimorphic pattern in the mouse brain

A major challenge in neuroscience lies in understanding how molecular and circuit differences in the brain synergistically contribute to sex differences in behavioral phenotypes. Sex differences in the brain may arise from the identity, distribution and relative abundance of cell types.

NCAM2 protein is a vital factor in the formation of cerebral cortex, neuronal morphogenesis

The molecule NCAM2, a glycoprotein from the superfamily of immunoglobulins, is a vital factor in the formation of the cerebral cortex, neuronal morphogenesis and formation of neuronal circuits in the brain, as stated in the new study published in the journal Cerebral Cortex.

Mouse study shows how associative fear memory is formed in the brain

How does the brain form "fear memory" that links a traumatic event to a particular situation? A pair of researchers at the University of California, Riverside, may have found an answer.

BIN1 deficit leads to impaired spatial learning and memory

Bridging integrator 1, known as BIN1, is the second most common risk factor for late-onset Alzheimer's disease, according to genome-wide studies of genetic variants. Yet, scientists know little about what this protein does in the brain.

UQ study identifies a major shift in how to treat brain injuries

Researchers have identified a major shift in how to treat brain injuries, after rejuvenating immune cells to support the repair process.

Innovative method bolsters memory processes in the brain during sleep

A new joint study by Tel Aviv University and Weizmann Institute of Science researchers has yielded an innovative method for bolstering memory processes in the brain during sleep.

Researchers uncover novel neurotransmitter system in the brain

Neurotransmitters are chemicals that transmit signals between neurons or from neurons to other cells. They interact with specific receptors found in the brain of humans and animals, controlling a variety of biological processes, e.g. fear, anger, pleasure, memory, energy, appetite and sleep.

Visceral fat gives signal to the brain that damages cognition

Excessive weight around our middle gives our brain's resident immune cells heavy exposure to a signal that turns them against us, setting in motion a crescendo of inflammation that damages cognition, scientists say.

Certain drugs can reduce epilepsy risk following traumatic brain injury

A research team led by a scientist at the University of California, Riverside, has found that brains treated with certain drugs within a few days of an injury have a dramatically reduced risk of developing epilepsy later in life.

What the western diet is doing to your brain

The Western Pattern Diet (WPD) or also known as the Standard American Diet (SAD) is a modern-day style diet that mostly contains high amounts of processed foods, red meat, high-fat dairy products, high-sugar foods, and pre-packaged foods, that increase the risk of chronic illness.

NRG Oncology trial: Hippocampal avoidance during whole-brain radiotherapy reduces risks

Results from the NRG Oncology clinical study NRG-CC001 concluded that lowering radiotherapy dose to hippocampal stem cells improves cognitive and patient-reported outcomes for patients with brain metastases.

Good blood supply to the brain associated with cognitive performance

Memory performance and other cognitive abilities benefit from a good blood supply to the brain. This applies in particular to people affected by a condition known as "sporadic cerebral small vessel disease".

New study provides clear picture of brain abnormalities associated with schizophrenia

What if the key to a better understanding of schizophrenia has been here all along--but researchers haven't had the resources to study it?

Accumulated brain protein affects genes in Alzheimer's disease

A new study published in February 2020 in the journal Cell Reports shows how the build-up of specific brain cell proteins are linked to altered gene expression that causes the symptoms of Alzheimer's disease (AD).

Marijuana use increases false memories finds study

A new study published this week has revealed that the use of marijuana or cannabis can implant false memories. The study titled, "Cannabis increases susceptibility to false memory," was published in the latest issue of the journal Proceedings of the National Academy of Sciences.

Neurons critical for learning and forming memories found to be synchronized

The phrase "Pavlov's dogs" has long evoked images of bells, food and salivating dogs. Even though this tried-and-true model of repetitive patterns mimics a variety of learning processes, what happens on a cellular level in the brain isn't clear.

Age-linked cognitive decline could be slowed by immune activation

A new study published in February 2020 in the Journal of Experimental Medicine (JEM), reports that activating a specific type of immune cell found in the brain could delay reduced cognition often found in older people, and even prevent neurologic degeneration of age.
