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.

Serotonin 2C receptor in the brain regulates memory in people and animal models, research shows

Researchers at Baylor College of Medicine, the University of Cambridge in the U.K. and collaborating institutions have shown that serotonin 2C receptor in the brain regulates memory in people and animal models.

Research explores reversing memory loss with existing drugs

The loss of social memories caused by sleep deprivation could potentially be reversed using currently available drugs, according to a study in mice presented today (Friday) at the Federation of European Neuroscience Societies (FENS) Forum 2024.

Brain responds differently to AI vs. human speech

People are not very good at distinguishing between human voices and voices generated by artificial intelligence (AI), but our brains do respond differently to human and AI voices, according to research presented today (Tuesday) at the Federation of European Neuroscience Societies (FENS) Forum 2024.

Brain processes immediate goals faster than distant ones

How does our brain distinguish between urgent and less urgent goals? Researchers at the University of Geneva (UNIGE) and the Icahn School of Medicine in New York have explored how our brain remembers and adjusts the goals we set ourselves on a daily basis.

Ovary removal before menopause could accelerate brain degeneration

Premenopausal bilateral oophorectomy (PBO) is linked to reduced white matter integrity in the brain, particularly in women who undergo PBO before the age of 40, suggesting potential long-term cognitive impacts.

Restoring youthful TERT levels reverses aging phenotypes in preclinical models

Researchers at The University of Texas MD Anderson Cancer Center have demonstrated that therapeutically restoring 'youthful' levels of a specific subunit of the telomerase enzyme can significantly reduce the signs and symptoms of aging in preclinical models.

How ketone bodies contribute to brain health and memory preservation

The ketogenic diet has its fanatics and detractors among dieters, but either way, the diet has a scientifically documented impact on memory in mice.

New AARF-D award supports Temple researchers to explore synapse function in the aging brain

Late-life depression is a major risk factor for Alzheimer's disease, in particular because it accelerates progression from mild cognitive impairment to dementia.

Study reveals bidirectional link between depression and memory decline in older adults

Depressive symptoms are linked to subsequent memory decline in older people, while poorer memory is also linked to an increase in depressive symptoms later on, according to a new study led by researchers at UCL and Brighton and Sussex Medical School.

Novel CMOS sensor captures fast and subtle neural voltage fluctuations

Neurons communicate electrically so to understand how they produce brain functions such as memory, neuroscientists must track how their voltage changes - sometimes subtly - on the timescale of milliseconds.

Mechanisms of aversive learning: How negative experiences shape neural circuits

'I'm not gonna do this again', we often say when faced with negative feedback, adverse effects, or disappointing outcomes. Thus, we attempt to learn from such negative experiences.

Ketones show promise in preventing cognitive decline and neurodegeneration

Researchers at the Del Monte Institute for Neuroscience at the University of Rochester have identified mechanisms in the brain's hippocampal network that are rescued by ketones.

Sleep unlocks neurons that anticipate future experience

Some dreams may, in fact, predict the future: New research has found that during sleep, some neurons not only replay the recent past but also anticipate future experience.

New Alzheimer's drug LM11A-31 shows promise in slowing disease progression in clinical trial

A recent study in Nature Medicine found that LM11A-31, targeting the p75 neurotrophin receptor, is safe and shows promise in slowing Alzheimer's disease progression. The trial indicated significant biomarker improvements and potential benefits for further clinical investigation.
