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.

UCLA-led study finds brain injury as cause of dementia in some older adults

A UCLA-led study finds that, with the use of MRI scans, it is possible to distinguish between memory loss caused by Alzheimer's disease and traumatic brain injury.

Scientists show how our memories stabilize while we sleep

Scientists at the Center for Interdisciplinary Research in Biology have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature.

New findings can redefine the diagnosis of mild cognitive impairment in men and women

Using sex-specific scores on memory tests may change the diagnosis for 20 percent of those currently diagnosed with mild cognitive impairment (MCI), with possibly more women and fewer men being diagnosed with MCI, according to a new study published online in the journal Neurology.

Neuroscientists show how different brain regions interact to create and retrieve memories

Neuroscientists at the University of Birmingham have proved how different parts of the human brain work together to create and retrieve episodic memory.

A period of rest could help ameliorate memory disturbances in PTSD

A period of rest following a traumatic event can reduce the subsequent development of involuntary 'memory intrusions', one of the hallmark symptoms in post-traumatic stress disorder, a new UCL study has found.

MSU researchers identify gender-distinct circuit for depression that activates during stress

Depression affects women nearly twice as much as men, but unraveling the brain's blueprint that regulates this behavior, let alone identifying specific molecular differences between sexes, has proven difficult.

Simple computer model helps better understand memory processing in the brain

Brains are a mazy network of overlapping circuits -- some pathways encourage activity while others suppress it.

Rapid progress in brain organoid research prompts ethical debate

A new paper has tried to address the ethical debate surrounding human organoids by evaluating the potential risks of creating “humanized” animals

New study pinpoints emergence and progression of Alzheimer's plaque in the brain

Long before symptoms like memory loss even emerge, the underlying pathology of Alzheimer's disease, such as an accumulation of amyloid protein plaques, is well underway in the brain.

Penn researchers propose ethical framework that defines brain organoid transplantation

As research involving the transplantation of human "mini-brains"--known as brain organoids--into animals to study disease continues to expand, so do the ethical debates around the practice.

Sex-differences in brain development linked with psychiatric and neurodevelopmental disorders

The amygdala and the hippocampus--structures in the brain that are involved in emotion, learning, and memory--have been found to play a role in a diverse range of disorders, such as attention-deficit/hyperactivity disorder (ADHD), anxiety, depression, and schizophrenia.

Study shows how brake cell failure causes some types of seizure disorders

A study has revealed that brake cell failure causes some types of seizure disorders.

WVU researcher explores the brain in a new way to better understand cognition

Where is Waldo? Whether we're searching for Waldo or our keys in a room of clutter, we tap into a part of the frontal region of the brain when performing visual, goal-related tasks. Some of us do it well, whereas for others it's a bit challenging.

Function of certain 'brake cells' disrupted in some forms of epilepsy

In some forms of epilepsy, the function of certain "brake cells" in the brain is presumed to be disrupted. This may be one of the reasons why the electrical malfunction is able to spread from the point of origin across large parts of the brain.

Cannabis: CBD vs THC causes lower psychiatric side-effects

A study has revealed how cannabidiol works against tetrahydrocannabinol to prevent psychiatric side effects.

Study shows how cannabidiol blocks the psychiatric side-effects of THC

Researchers at Western University have shown for the first time the molecular mechanisms at work that cause cannabidiol, or CBD, to block the psychiatric side-effects caused by tetrahydrocannabinol, the main psychoactive chemical in cannabis.

Lifelong choline supplementation holds potential to prevent Alzheimer's disease

In a new study, Biodesign researchers reveal that a lifelong dietary regimen of choline holds the potential to prevent Alzheimer's disease.

Scientists discover how neural circuits play critical role in learning and memory

A University of California, Irvine-led team of scientists has discovered how newly identified neural circuits in the brain's hippocampal formation play a critical role in object-location learning and memory.

Neuroscientists analyze why the brain is disturbed by harsh sounds

Why do the harsh sounds emitted by alarms or human shrieks grab our attention? What is going on in the brain when it detects these frequencies?

Whole-brain radiotherapy recommended for patients with brain metastases

Patients with brain metastases who received whole-brain radiotherapy that avoided memory-specific hippocampal neural stem cells experienced preserved cognitive function and reported fewer neurologic symptoms and better cognition over time, according to results from an NRG Oncology clinical trial presented Sept. 15, 2019 at the American Society for Radiation Oncology Annual Meeting in Chicago.
