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.

Receptors crucial for establishing strong memories

When we create a memory, a pattern of connections forms between neurons in the brain. New work from UC Davis shows how these connections can be strengthened or weakened at a molecular level. The study is published Feb. 27 in the journal Cell Reports.

New neurons in adult brain help speed up association between sensory information and reward

Although we have known for several years that the adult brain can produce new neurons, many questions about the properties conferred by these adult-born neurons were left unanswered.

Iron deficiency early in life can have long-lasting consequences for the brain

Iron deficiency in the first four weeks of a piglet's life - equivalent to roughly four months in a human infant - impairs the development of key brain structures, scientists report. The abnormalities remain even after weeks of iron supplementation begun later in life, the researchers found.

Liquefied brain tissue after stroke may harm surviving brain, UA study finds

Scientists have known for years that the brain liquefies after a stroke. If cut off from blood and oxygen for a long enough period, a portion of the brain will die, slowly morphing from a hard, rubbery substance into liquid goop.

Study reveals biological relevance of sex in effects of D-galactose induced aging

A research study by the Universitat Autònoma de Barcelona in collaboration with the University of La Laguna demonstrates in mice the biological relevance of sex in the effects of accelerated ageing caused by a chronic treatment of D-galactose, a sugar found abundantly in milk and to a lesser extent in fruits and vegetables.

Running mitigates negative impacts of chronic stress on the brain, study finds

Most people agree that getting a little exercise helps when dealing with stress. A new BYU study discovers exercise -- particularly running -- while under stress also helps protect your memory.

Researcher makes breakthrough discovery in process of fear relapse

Steve Maren, the Claude H. Everett Jr. '47 Chair of Liberal Arts professor in the Department of Psychological and Brain Sciences at Texas A&M University, and his Emotion and Memory Systems Laboratory have made a breakthrough discovery in the process of fear relapse.

MRI scans reveal why people often become aggressive after drinking alcohol

Researchers have used magnetic resonance imaging scans that measure blood flow in the brain to better understand why people often become aggressive and violent after drinking alcohol.

Dim light may affect your ability to learn and remember, suggests new study

A new study found that prolonged exposure to dim light may alter the brain's structure, and impair an individual’s ability to remember and learn.

Neurons get stretches of orderly drumroll-like rumblings speckled with strong impulses

A neuron firing deep in the brain might sound a little like: Drumroll...cymbal crash! Drumroll...cymbal crash! Repeat. With emphasis on "repeat," according to a new study.

Neuroscientists identify 'anxiety cells' in the brain's hippocampus

Do your palms sweat when you walk down a poorly lit street at night? That feeling may be traced to the firing of newly identified "anxiety" cells deep inside your brain, according to new research from neuroscientists at Columbia University Irving Medical Center and the University of California, San Francisco.

Virtual reality provides new insight into how different brain areas assemble memories

Virtual reality is helping neuroscientists at the University of California, Davis, get new insight into how different brain areas assemble memories in context.

Findings provide better understanding of cognitive inflexibility in Fragile X Syndrome

Mice with the genetic defect that causes Fragile X syndrome (FXS) learn and remember normally, but show an inability to learn new information that contradicts what they initially learned, shows a new study by a team of neuroscientists.

Study shows high-salt diet causes dementia in mice

A high-salt diet reduces resting blood flow to the brain and causes dementia in mice, according to a new study by scientists from Weill Cornell Medicine.

Researchers use Quest MRI to identify earliest signs of Alzheimer's disease in mice

Alzheimer's disease wreaks emotional havoc on patients, who are robbed of their memories, their dignity, and their lives. It's financially devastating as well: care for Alzheimer's patients is predicted to top $1 trillion by about the time children born today are having children of their own.

Neuroscientists examine why the brain stores some odors as long-term memories

The neuroscientists Dr Christina Strauch and Prof Dr Denise Manahan-Vaughan from the Ruhr-Universität Bochum have investigated which brain area is responsible for storing odors as long-term memories.

Study explores use of radiosurgery in lung cancer patients with multiple brain metastases

Although targeted therapies have produced dramatic advances in our ability to control some types of advanced lung cancer, growth of the disease in the brain remains a major problem.

Walking more than 4,000 steps a day can improve attention, mental skills in older adults

Walking more than 4,000 steps a day can improve attention and mental skills in adults ages 60 and older, according to UCLA research published December 12 in a preprint edition of the Journal of Alzheimer's Disease.

New findings may lead to sensitive, non-invasive test for Alzheimer's disease

New research has drawn a link between changes in the brain's anatomy and biomarkers that are known to appear at the earliest stages of Alzheimer's disease (AD), findings that could one day provide a sensitive but non-invasive test for AD before cognitive symptoms appear.

Studies highlight potential of fMRI applications to detect, treat epilepsy in children

Functional magnetic resonance imaging has allowed researchers to map the memory functions that are often impaired within the brains of children with epilepsy.
