Hippocampus News and Research RSS Feed - Hippocampus News and Research

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.
Mutations in gene that enables memories, sense of direction can contribute to schizophrenia symptoms

Mutations in gene that enables memories, sense of direction can contribute to schizophrenia symptoms

Mutations in a gene that should enable memories and a sense of direction instead can result in imprecise communication between neurons that contributes to symptoms of schizophrenia, scientists report. [More]
Study identifies molecular signals that maintain nerve cell structures in the adult brain

Study identifies molecular signals that maintain nerve cell structures in the adult brain

Humans and other vertebrates depend on a portion of the brain called the hippocampus for learning, memory and their sense of location. Nerve cell structures in the adult hippocampus are sustained by factors whose identities have remained largely mysterious so far. [More]

Scientists discover new molecular information on how the brain regulates depression and anxiety

Researchers have made a ground-breaking discovery revealing new molecular information on how the brain regulates depression and anxiety. [More]
Study challenges concept of gender differences in the human brain

Study challenges concept of gender differences in the human brain

How different are men and women's brains? The latest evidence to address this controversy comes from a study at Rosalind Franklin University of Medicine and Science, where a meta-analysis of human amygdala volumes found no significant difference between the sexes. [More]
Could pathogen infection really lead to Alzheimer’s?

Could pathogen infection really lead to Alzheimer’s?

New concepts of infectious disease are evolving with the realization that pathogens are key players in the development of progressive chronic diseases that originally were not thought to be infectious. Infection is well-known to be associated with numerous neurological diseases for which... [More]
Stress hormone has major effect on perception and perceptual learning

Stress hormone has major effect on perception and perceptual learning

Stress is part of our everyday lives - while some thrive on it, it makes others sick. But what does stress do to our senses? When we train them, we can sharpen our senses thereby improve our perceptual performance. [More]
Scientists identify molecular pathway in the brain that may help find better treatments for dementia

Scientists identify molecular pathway in the brain that may help find better treatments for dementia

Rutgers University scientists have discovered a molecular pathway in the brain that may help provide answers to long-term memory problems in the elderly and aid researchers in identifying drug-based therapies to prevent dementia. [More]
Researchers identify mechanism that generates synchronous oscillation in the brain

Researchers identify mechanism that generates synchronous oscillation in the brain

Every time we learn something new, the memory does not only need to be acquired, it also needs to be stabilized in a process called memory consolidation. [More]
UC San Diego research identifies neurons that signal direction of travel

UC San Diego research identifies neurons that signal direction of travel

Imagine you're navigating a city like New York, or any other that's laid out on a grid. Suppose you run into a roadblock as you're heading north. [More]
Study improves molecular understanding of the brain in people with epilepsy

Study improves molecular understanding of the brain in people with epilepsy

Neural stem cells have been found in epileptic brain tissue—outside the regions of the brain where they normally reside. In a group of patients who underwent surgery for epilepsy, over half had stem cells where healthy individuals do not have them, according to a study from Sahlgrenska Academy. [More]
Moderate exercise may help treat memory impairment in patients with type 2 diabetes

Moderate exercise may help treat memory impairment in patients with type 2 diabetes

University of Tsukuba-led researchers show that moderate exercise may improve hippocampal memory dysfunction caused by type 2 diabetes and that enhanced transport of lactate to neurons may be the underlying mechanism [More]
Rhythm of breathing influences emotional judgments and memory recall

Rhythm of breathing influences emotional judgments and memory recall

Northwestern Medicine scientists have discovered for the first time that the rhythm of breathing creates electrical activity in the human brain that enhances emotional judgments and memory recall. [More]
BUSM researchers discover role of hippocampus in future thinking

BUSM researchers discover role of hippocampus in future thinking

Over the past decade, researchers have learned that the hippocampus--historically known for its role in forming memories--is involved in much more than just remembering the past; it plays an important role in imagining events in the future. [More]
Researcher explores link between PTSD and repeated alcohol use

Researcher explores link between PTSD and repeated alcohol use

As families gather for the holidays this year, many will reminisce, sharing fond memories as they break bread and pass the cranberry sauce. [More]
Johns Hopkins researchers find evidence of brain injury in young NFL players

Johns Hopkins researchers find evidence of brain injury in young NFL players

In a small study of young or recently retired NFL players, researchers at Johns Hopkins report finding evidence of brain injury and repair that is visible on imaging from the players compared to a control group of men without a history of concussion. [More]
Enzyme research provides new insights into pathophysiology of depression

Enzyme research provides new insights into pathophysiology of depression

Despite the fact that more than four percent of the world's population suffer from depression, and even though approximately 1,500 individuals commit suicide each year in Sweden, the understanding of the pathophysiology of depression remains unclear and only a few new discoveries of mechanisms behind it have been made in recent years.

Study using Cubresa SPECT scanner finds potential non-invasive diagnosis for Alzheimer’s

Study using Cubresa SPECT scanner finds potential non-invasive diagnosis for Alzheimer’s

Cubresa’s SPECT scanner was used to determine if a novel molecular label, TRV6001, in development for in vivo imaging of the BChE enzyme present in the brains of Alzheimer’s Disease patients follows the known distribution of the enzyme in animal models of the disease. [More]
Study finds abnormally low blood flow in the brain of marijuana users

Study finds abnormally low blood flow in the brain of marijuana users

As the U.S. races to legalize marijuana for medicinal and recreational use, a new, large scale brain imaging study gives reason for caution. [More]
New study finds link between memory mechanisms and resistance to epilepsy

New study finds link between memory mechanisms and resistance to epilepsy

A new study undertaken jointly by researchers from the Sagol Department of Neurobiology at the University of Haifa and European researchers, published in the journal Cerebral Cortex, exposes a new biological mechanism that, on the one hand, damages a very specific type of memory, but at the same time provides resistance to epilepsy.

Circular ‘Princess Leia’ oscillations help sleeping brain consolidate memories

Circular ‘Princess Leia’ oscillations help sleeping brain consolidate memories

Every night while you sleep, electrical waves of brain activity circle around each side of your brain, tracing a pattern that, were it on the surface of your head, might look like the twin hair buns of Star Wars' Princess Leia. [More]
