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.

Could camembert cheese hold the key to better memory?

Myristamide enhances cognitive function and BDNF in mice, indicating Camembert cheese's potential in combating cognitive decline and supporting brain health.

Sleep deprivation inhibits the brain's ability to suppress unwanted memories

A new study has shown that sleep deprivation can inhibit the brain's ability to suppress unwanted memories and intrusive thoughts.

Blood test could help track Alzheimer's disease progression and severity

Declining blood levels of two molecules that occur naturally in the body track closely with worsening Alzheimer's disease, particularly in women.

Sleep deprivation disrupts brain regions that prevent unwanted memories

The link between poor sleep and mental health problems could be related to deficits in brain regions that keep unwanted thoughts out of mind, according to research from the University of East Anglia (UEA).

Taxi and ambulance drivers show lower Alzheimer’s risk

Study reveals that taxi and ambulance drivers, whose jobs demand frequent spatial and navigational processing, have lower Alzheimer's disease-related mortality compared to other professions. These findings suggest a potential link between occupational cognitive demands and AD risk.

A new link between brain health and mitochondrial function

New findings in mice have uncovered a crucial mechanism linking neuronal activity to mitochondrial function, researchers report, revealing a potential pathway to combat age-related cognitive decline. Mitochondria play a pivotal role in meeting the dynamic energy demands of neuronal activity, producing adenosine triphosphate (ATP) primarily via oxidative phosphorylation (OXPHOS).

New molecular insights into the early stages of Rett syndrome

Scientists investigating the severe developmental disorder known as Rett syndrome have discovered a series of crucial molecular changes that occur long before symptoms appear.

Chemogenetic activation reveals male-female differences in stress resistance neural circuits

Subtle activation of a small subset of neurons in one region of the brain can make male mice resilient to, and even reverse, the detrimental effects of chronic stress. The same is true for female mice, but in a totally different region of the brain.

Hippocampal inflammation affects behavior differently in males and females

Inflammation in the hippocampus – the brain's memory centre – significantly alters motivation and behavior in mice, including food-seeking behaviour, with notable differences between males and females, a recent study reveals.

Sleep disruptions may increase brain volume in the hippocampus

People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a study published in the December 18, 2024, online issue of Neurology, the medical journal of the American Academy of Neurology.

Taxi and ambulance drivers show reduced Alzheimer’s mortality

Taxi drivers and ambulance drivers, whose jobs require frequent spatial and navigational processing, have the lowest levels of death due to Alzheimer's disease compared with other occupations, finds a study in the Christmas issue of The BMJ.

18 Dec 2024

Driving occupations could lead to lower rates of death from Alzheimer's disease

A new study raises the possibility that jobs that require frequent spatial processing - such as figuring out a taxi route or the best way to navigate to a hospital - could lead to lower rates of death from Alzheimer's disease.

Breathing rhythms coordinate brain waves to strengthen memory during sleep

Just as a conductor coordinates different instruments in an orchestra to produce a symphony, breathing coordinates hippocampal brain waves to strengthen memory while we sleep, reports a new Northwestern Medicine study.

Portable MRI and AI improve Alzheimer’s diagnosis with cost-effective precision

Researchers optimized portable low-field MRI with machine learning to improve brain morphometry and white matter hyperintensity detection, making Alzheimer's diagnosis more accessible and cost-effective.

Study sheds light on how deep sleep supports memory formation

It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories.

Common brain network connected to heterogeneous patterns of brain atrophy in schizophrenia

A new study led by investigators from Mass General Brigham has identified a unique brain network that links varied patterns of brain atrophy, or shrinkage, associated with schizophrenia.

Exercise enhances memory for up to 24 hours, study finds

The short-term boost our brains get after we do exercise persists throughout the following day, suggests a new study led by UCL (University College London) researchers.

Mouse study links glyphosate to Alzheimer's-like brain changes and anxiety

Glyphosate exposure in mice exacerbates Alzheimer's-like neuropathologies, increases neuroinflammation, and leaves lasting effects, even after prolonged recovery.

Brain signature of resilience suggests a new way to recovery from trauma

Researchers at UCSF find a brain signature of resilience in mice that suggests a new way of treating severe depression.
