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.

New discovery can allow scientists to tell old and new memories apart

Researchers have discovered signatures in brain activity that allow them to tell old and new memories apart. A team at Japan's RIKEN Center for Brain Science analyzed recordings from mouse brains using a machine-leaning algorithm, which was able to accurately classify memories as recent or remote. They also found robust communication between a frontal brain region and the hippocampus, an area strongly involved in memory formation.

Impulsive eating could stem from certain regions of the brain

Weight loss mandates healthy eating and control of impulses when it comes to eating fat rich and processed foods. The actual story is quite different, as most persons on a diet have found out the hard way. The smell of food and even thoughts have given rise to binge eating, indulging in excessive food intake that has led to obesity and weight gain.

New review explores relationship between yoga practice and brain health

Scientists have known for decades that aerobic exercise strengthens the brain and contributes to the growth of new neurons, but few studies have examined how yoga affects the brain.

Novel self-powered, neural-stimulating e-skin for characterization of synaptic plasticity

Chinese scientists recently developed a flexible electronic skin (e-skin) capable of self-powered neural stimulation and inducing a neural response. The technology will be useful in characterizing synaptic plasticity.

Specific brain circuit linked to food impulsivity discovered

You're on a diet, but the aroma of popcorn in the movie theater lobby triggers a seemingly irresistible craving.

Study could help improve GENUS to become a therapeutic approach for Alzheimer's disease

The sweeping extent to which increasing 40Hz "gamma" rhythm power in the brain can affect the pathology and symptoms of Alzheimer's disease in mouse models has been surprising, even to the MIT neuroscientists who've pioneered the idea. So surprising, in fact, they can't yet explain why it happens.

Blood pressure drug could be beneficial in treating alcohol use disorders

A drug used to treat high blood pressure may alleviate anxiety induced by long-term heavy alcohol use, and also halt the damage such drinking can cause to the brain's ability to grow new cells, research at the Queensland University of Technology shows.

Insights from virtual reality experiments could help break the cycle of addiction

The number of drug overdose deaths in the US has never been higher. Most of those deaths--68 percent in 2017--have involved opioids. An estimated 10 million Americans aged 12 and older misused opioids in 2018.

Exposure to extreme environmental conditions can affect the human brain

Members of a polar research expedition have provided researchers from Charité - Universitätsmedizin Berlin and the Max Planck Institute for Human Development with an opportunity to study the effects of social isolation and extreme environmental conditions on the human brain. The researchers found changes to the dentate gyrus, an area of the hippocampus responsible for spatial thinking and memory.

Researchers reveal why granule cells and interneurons process information differently

The dentate gyrus is the "input point" for the hippocampus part of the brain. It transmits information from the short term memory to the long term. It consists of granule cells, which are especially dense in this area of the brain, and interneurons, which are linked up in the central or peripheral nervous system between several nerve cells and have an inhibiting effect on their activity. Both types of cell process information and differentiate closely-related memories.

Study advances understanding of mechanisms involved in functional neurological disorder

Individuals with functional neurological disorder have symptoms not explained by traditional neurological conditions, including limb weakness, tremor, gait abnormalities, seizures and sensory deficits.

Extra virgin olive oil boosts brain power

Researchers from the Lewis Katz School of Medicine at Temple University have found that extra virgin olive oil (EVOO) could help boost brain power and help halt the progression of the effects of aging on the brain. The study was published in the latest issue of the journal Aging Cell, and it was titled, “Extra virgin olive oil improves synaptic activity, short‐term plasticity, memory, and neuropathology in a tauopathy model.”

UCI researchers develop new cell therapy to improve memory, prevent seizures after TBI

Researchers from the University of California, Irvine developed a breakthrough cell therapy to improve memory and prevent seizures in mice following traumatic brain injury.

Scientists reverse learning and memory deficits with drugs in animal model of Down syndrome

In a surprising finding using the standard animal model of Down syndrome (DS), scientists were able to correct the learning and memory deficits associated with the condition -- the leading genetic cause of cognitive disability and the most frequently diagnosed chromosomal disorder in the U.S. -- with drugs that target the body's response to cellular stresses.

Lithium corrects radiation damage to brain in young cancer patients

A new study on mice, published online in the journal Molecular Psychiatry, on November 14, 2019, shows that the intermittent use of lithium, which is widely used to stabilize the mood in conditions such as bipolar disorder, can correct memory and learning losses due to radiation therapy to the brain in very young animals, even when the lithium is given long after the injury.

Study sheds new light on the brain's spatial map

An important aspect of human memory is our ability to conjure specific moments from the vast array of experiences that have occurred in any given setting. For example, if asked to recommend a tourist itinerary for a city you have visited many times, your brain somehow enables you to selectively recall and distinguish specific memories from your different trips to provide an answer.

Musical pleasure linked to right combination of uncertainty and surprise

Why is it that people find songs such as James Taylor's "Country Roads," UB40's "Red, Red Wine," or The Beatles' "Ob-La-Di, Ob-La-Da" so irresistibly enjoyable? In a study reported in the journal Current Biology on November 7, researchers analyze 80,000 chords in 745 classic U.S. Billboard pop songs--including those three--and find that musical pleasure comes from the right combination of uncertainty and surprise.

Research identifies neural pathway involved in memory consolidation during sleep

A new study could supply the missing link in the story of the brain consolidates floating memories into a permanent structure while we sleep. The study, published in the journal eNeuro, shows how a brain region, appropriately called the nucleus reuniens, ‘goes between’ two other memory-linked structures – the hippocampus and the prefrontal cortex.

Study uncovers cause for spatial-memory deficits in people with Down syndrome

Professor Juan Lerma's group, from the UMH-CSIC Institute of Neurosciences, in Alicante, has identified the gene called GRIK1, fundamental in the balance between excitation and inhibition in the brain, as one of the causes for people with Down syndrome having spatial orientation problems.

Patterns of Alzheimer's-related damage differ by subtype and age of onset, study finds

Despite decades of scientific scrutiny, Alzheimer's disease researchers have yet to work out its cause or treatment. Understanding what underlies its three distinct subtypes is thought to be a promising new research avenue.
