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.
Research: MHCI protein moonlights in nervous system to regulate synapses

Research: MHCI protein moonlights in nervous system to regulate synapses

When it comes to the brain, "more is better" seems like an obvious assumption. But in the case of synapses, which are the connections between brain cells, too many or too few can both disrupt brain function. [More]

Vanderbilt engineers develop robotic device for less invasive epilepsy surgery

For those most severely affected, treating epilepsy means drilling through the skull deep into the brain to destroy the small area where the seizures originate - invasive, dangerous and with a long recovery period. [More]
Researchers use light to erase specific memories in mice

Researchers use light to erase specific memories in mice

Just look into the light: not quite, but researchers at the UC Davis Center for Neuroscience and Department of Psychology have used light to erase specific memories in mice, and proved a basic theory of how different parts of the brain work together to retrieve episodic memories. [More]
Scientists use novel way to identify new gene linked to Alzheimer's

Scientists use novel way to identify new gene linked to Alzheimer's

Scientists at The University of Manchester have used a new way of working to identify a new gene linked to neurodegenerative diseases such as Alzheimer's. The discovery fills in another piece of the jigsaw when it comes to identifying people most at risk of developing the condition. [More]
New findings link obesity and dietary factors to late-life dementias

New findings link obesity and dietary factors to late-life dementias

Difficulties learning, remembering, and concentrating. An inability to resist environmental temptations to eat. A lifetime of progressive deterioration in the brain. [More]
USC researchers develop new methods to advance study of human brains, epilepsy

USC researchers develop new methods to advance study of human brains, epilepsy

USC biomedical engineers, neurologists and neurosurgeons develop new methods to advance the study of human brains and epilepsy. Studying the human brain is logistically complicated. Living samples of the complex and sensitive organ are limited and difficult to preserve, which means that research on them must be conducted quickly before they expire. [More]
Sugar consumption linked to memory problems, brain inflammation in adolescent rats

Sugar consumption linked to memory problems, brain inflammation in adolescent rats

Studying rats as model subjects, scientists found that adolescents were at an increased risk of suffering negative health effects from sugar-sweetened beverage consumption. [More]
Research findings could help find ways to enhance overall learning, memory

Research findings could help find ways to enhance overall learning, memory

The more curious we are about a topic, the easier it is to learn information about that topic. New research publishing online October 2 in the Cell Press journal Neuron provides insights into what happens in our brains when curiosity is piqued. [More]
New study sheds light on longstanding question about role of mitochondria in motor neuron diseases

New study sheds light on longstanding question about role of mitochondria in motor neuron diseases

A new study by researchers at the University of Utah School of Medicine sheds light on a longstanding question about the role of mitochondria in debilitating and fatal motor neuron diseases and resulted in a new mouse model to study such illnesses. [More]
Researchers identify control mechanism for mood disorders

Researchers identify control mechanism for mood disorders

Researchers at University of California, San Diego School of Medicine have identified a control mechanism for an area of the brain that processes sensory and emotive information that humans experience as "disappointment." [More]
Activation of MMP-9 enzyme leads to behavioral problems connected to chronic stress

Activation of MMP-9 enzyme leads to behavioral problems connected to chronic stress

Why is it that when people are too stressed they are often grouchy, grumpy, nasty, distracted or forgetful? Researchers from the Brain Mind Institute at EPFL have just highlighted a fundamental synaptic mechanism that explains the relationship between chronic stress and the loss of social skills and cognitive impairment. When triggered by stress, an enzyme attacks a synaptic regulatory molecule in the brain. This was revealed by a work published in Nature Communications. [More]
UAB researchers discover novel mechanism involved in formation of memory, learning

UAB researchers discover novel mechanism involved in formation of memory, learning

Researchers at the University of Alabama at Birmingham report the discovery of a novel mechanism in the brain involved in the formation of memory and learning. In findings reported online this week in Nature, the research team describes the role of a histone subunit known as H2A.Z. [More]
New research illustrates how fear arises in the brain

New research illustrates how fear arises in the brain

An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain. [More]
UC Irvine study sheds light on cognitive losses

UC Irvine study sheds light on cognitive losses

Brain inflammation can rapidly disrupt our ability to retrieve complex memories of similar but distinct experiences, according to UC Irvine neuroscientists Jennifer Czerniawski and John Guzowski. [More]
New way to preserve flexibility and resilience of the brain

New way to preserve flexibility and resilience of the brain

As Alzheimer's disease progresses, it kills brain cells mainly in the hippocampus and cortex, leading to impairments in "neuroplasticity," the mechanism that affects learning, memory, and thinking. [More]
Brain imaging could assist bipolar depression diagnosis

Brain imaging could assist bipolar depression diagnosis

Researchers have identified structural brain differences that could help to distinguish patients with unipolar and bipolar depression. [More]
Mice who have partial deficiency of gene SENP2 are more likely to develop seizures, sudden death

Mice who have partial deficiency of gene SENP2 are more likely to develop seizures, sudden death

A gene crucial for brain and heart development may also be associated with sudden unexplained death in epilepsy (SUDEP), the most common cause of early mortality in epilepsy patients. [More]
Finding could lead researchers to better understand development of psychiatric disorders

Finding could lead researchers to better understand development of psychiatric disorders

Some people take stress in stride; others are done in by it. New research at Rockefeller University has identified the molecular mechanisms of this so-called stress gap in mice with very similar genetic backgrounds - a finding that could lead researchers to better understand the development of psychiatric disorders such as anxiety and depression.

Study for better understanding of neural circuitry and dynamic mechanisms controlling memory

A study just published in the prestigious Nature Neuroscience journal by, Sylvain Williams, PhD, and his team, of the Research Centre of the Douglas Mental Health University Institute and McGill University, opens the door towards better understanding of the neural circuitry and dynamic mechanisms controlling memory as well of the role of an essential element of the hippocampus - a sub-region named the subiculum.

Neuroscientists explore how imagination happens in the brain

Stefania Ashby and her faculty mentor devised experiments using MRI technology that would help them distinguish pure imagination from related processes like remembering. [More]
