Precise inactivation of neurotransmitter receptors using CALI technique erases fear memory in mice

The delivery of chemical messenger (neurotransmitter) receptors to the junctions between nerve cells (synapses) is crucial to cognitive processes such as memory.

Multi-disciplinary project receives £390,000 grant to discover genetic cause of epilepsy

The University of Liverpool has received a £390,000 grant from Medical Research Council to conduct research into how mutations in genes can cause epilepsy.

New laser activated technique sheds light on memory loss conditions

Researchers at Hiroshima University have developed a new laser activated technique for bridging missing links in memory flow.

Alcohol strengthens emotional memories linked to fearful experiences, study shows

Experiments in mice by researchers at Johns Hopkins suggest that if the goal is to ease or extinguish fearful emotional memories like those associated with post-traumatic stress disorder, alcohol may make things worse, not better.

Scientists devise new radiation-free probe for imaging molecules in the brain

Scientists hoping to get a glimpse of molecules that control brain activity have devised a new probe that allows them to image these molecules without using any chemical or radioactive labels.

New research provides insights into how gut microbes drive host gene expression

In our guts, and in the guts of all animals, resides a robust ecosystem of microbes known as the microbiome. Consisting of trillions of organisms — bacteria, fungi and viruses — the microbiome is essential for host health, providing important services ranging from nutrient processing to immune system development and maintenance.

Arthritis drug increases effectiveness of antidepressants in bipolar patients

Giving severely depressed patients the arthritis drug celecoxib (Celebrex) dramatically boosted the effectiveness of their antidepressant medication, a Loyola study has found.

Cannabinoid receptors regulate memory processes by modulating mitochondrial energy metabolism

It has been known for some time that the extracts of the Cannabis plant, just like synthetic cannabinoids and those produced by the brain itself, join up with type 1 (CB1) cannabinoid receptors located in the nerve endings of the neurons, and inhibit the release of chemical messengers (neurotransmitters) in the communication areas between the nerve cells.

MIT neuroscientists identify brain cells that play vital role in controlling appetite

MIT neuroscientists have discovered that brain cells called glial cells play a critical role in controlling appetite and feeding behavior.

Researchers discover how appetite is controlled and influenced by the brain

Researchers from Daegu Gyeongbuk Institute of Science and Technology in Korea have uncovered the mechanisms behind the enzyme that controls our appetite in response to low glucose availability in the brain.

DGIST researchers uncover mechanisms that control appetite during low glucose conditions in the brain

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in Korea have uncovered the mechanisms behind the enzyme that controls our appetite in response to low glucose availability in the brain.

Transcranial direct current stimulation may activate the human cerebral cortex, study shows

The notion that low levels of electrical stimulation applied to the scalp, barely enough to create a mild tingling sensation, could activate the brain is a relatively new and somewhat controversial idea.

$Developmental exposure to fracking chemicals may pose threat to fertility$

Developmental exposure to fracking chemicals may pose threat to fertility

More than 15 million Americans live within a one-mile radius of unconventional oil and gas operations. UOGs combine directional drilling and hydraulic fracturing, or "fracking," to release natural gas from underground rock.

New drug target could help prevent opioid tolerance and addiction

Researchers have identified a brain mechanism that could be a drug target to help prevent tolerance and addiction to opioid pain medication, such as morphine, according to a study by Georgia State University and Emory University.

NIH researchers discover rare, lethal inflammatory disease that affects young children

National Institutes of Health researchers have discovered a rare and sometimes lethal inflammatory disease - otulipenia - that primarily affects young children. They have also identified anti-inflammatory treatments that ease some of the patients' symptoms: fever, skin rashes, diarrhea, joint pain and overall failure to grow or thrive.

New laboratory model replicates early phase of Parkinson's before onset of motor symptoms

They're two of the biggest mysteries in Parkinson's disease research--where does the disease start? And how can it be stopped early in the process? Now, a new laboratory model of Parkinson's is giving scientists an inside look at what happens in the brain years before motor symptoms appear.

Japanese researchers suggest link between stimulus response and consciousness

Japanese researchers centered at Nagoya University reveal a role for orexin neurons of the hypothalamus when mice respond to painful stimuli, and suggest a link between stimulus response and consciousness.
