Dendritic spines respond to and process synaptic inputs both chemically and electrically

It's the least understood organ in the human body: the brain, a massive network of electrically excitable neurons, all communicating with one another via receptors on their tree-like dendrites. Somehow these cells work together to enable great feats of human learning and memory. But how?

New pathway appears to play a major role in information processing in the brain

Scientists at The Scripps Research Institute (TSRI) have identified a new pathway that appears to play a major role in information processing in the brain. Their research also offers insight into how imbalances in this pathway could contribute to cognitive abnormalities in humans.

Researchers simulate activity of cultured neural networks

After a short period of growth, cultured networks of neurons regularly exhibit major activity in the absence of external stimulation. These "bursts" are entirely related to growth. At this stage, they have little to do with learning behaviour, as the network is still too young to sustain a process of memory formation. This has now for the first time been simulated for networks ranging in size from 10,000 to 50,000 neurons. The simulations provide insight into the role of the growth process in initial activity.

Unique bond between SAP102 and GluN2B enables learning and memory

Two proteins have a unique bond that enables brain receptors essential to learning and memory to not only get and stay where they're needed, but to be hauled off when they aren't, researchers say.

WSU researcher examines use of carbon fiber microelectrodes in neurochemical measurements

A Wayne State University researcher's take on the current state of brain chemical analysis is the cover story in a recent professional journal, accompanied by a podcast.

ACIS Anterior Cervical Interbody Spacer System launched by DePuy Synthes Spine

DePuy Synthes Spine today announced the launch of the ACIS Anterior Cervical Interbody Spacer System (ACIS System), a comprehensive set of spacers and instrumentation for anterior cervical discectomy and fusion (ACDF).

Mephedrone and memory loss: an interview with Craig Motbey

Mephedrone is a fairly new designer drug which has been around for a few years. It exploded in popularity in Europe (and particularly in the UK) before it started to spread in a major way elsewhere.

New drug candidate improves cognitive function of rats with Alzheimer's-like mental impairment

Washington State University researchers have developed a new drug candidate that dramatically improves the cognitive function of rats with Alzheimer's-like mental impairment.

Common RNA pathway links frontotemporal lobar dementia with ALS

Two proteins previously found to contribute to ALS, also known as Lou Gehrig's disease, have divergent roles. But a new study, led by researchers at the Department of Cellular and Molecular Medicine at the University of California, San Diego School of Medicine, shows that a common pathway links them.

Fear hard to extinguish from the teenage brain

A new study by Weill Cornell Medical College researchers shows that adolescents' reactions to threat remain high even when the danger is no longer present. According to researchers, once a teenager's brain is triggered by a threat, the ability to suppress an emotional response to the threat is diminished which may explain the peak in anxiety and stress-related disorders during this developmental period.

Increasing marijuana-like chemicals in the brain can help correct behavioral issues related to fragile X

American and European scientists have found that increasing natural marijuana-like chemicals in the brain can help correct behavioral issues related to fragile X syndrome, the most common known genetic cause of autism.

First extensive analysis of Allen Human Brain Atlas

Scientists at the Allen Institute for Brain Science reported in the latest issue of the journal Nature that human brains share a consistent genetic blueprint and possess enormous biochemical complexity. The findings stem from the first deep and large-scale analysis of the vast data set publicly available in the Allen Human Brain Atlas.

Neuronal inhibition plays key role in memory formation

Stefan Remy and colleagues at the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn have illuminated how this system works. "The system acts like a filter, only letting the most important impulses pass," explains Remy. "This produces the targeted neuronal patterns that are indispensible for long-term memory storage."

Book examines highly complex structures of synaptic regions

Synapses are bulbous structures where two neurons communicate. Neurotransmitter molecules released from the presynaptic terminal of one neuron diffuse to the postsynaptic terminal on the other, binding to receptors that lead to propagation or modulation of the signal.

Study might help solve the biggest mystery of Parkinson’s

The recent discoveries that α-Synuclein(α-Syn) protein, a central player in Parkinson´s disease (PD) brain destruction, could not only pass from one neuron to another but also exist outside neuronal cells has led to major rethink on the disease.

Trial to test efficacy of NeuRx Diaphragm Pacing System in people with Lou Gehrig's disease

The Muscular Dystrophy Association (MDA) and The ALS Association today announced a joint commitment to provide funding for a phase 2 clinical trial that will test efficacy of the NeuRx Diaphragm Pacing System (DPS) in people with amyotrophic lateral sclerosis (ALS).

Scientists develop new way to study role of GABA-A receptors in various disorders

A new way to study the role of a critical neurotransmitter in disorders such as epilepsy, anxiety, insomnia, depression, schizophrenia, and alcohol addiction has been developed by a group of scientists led by Gong Chen, an associate professor of biology at Penn State University.

Study shows how neurons in the brain select information needed to keep us in balance

If you have ever looked over the edge of a cliff and felt dizzy, you understand the challenges faced by people who suffer from symptoms of vestibular dysfunction such as vertigo and dizziness. There are over 70 million of them in North America. For people with vestibular loss, performing basic daily living activities that we take for granted (e.g. dressing, eating, getting in and out of bed, getting around inside as well as outside the home) becomes difficult since even small head movements are accompanied by dizziness and the risk of falling.

Scientists uncover how internal mechanisms in nerve cells wire the brain

Scientists at the University of Manchester have uncovered how the internal mechanisms in nerve cells wire the brain. The findings open up new avenues in the investigation of neurodegenerative diseases by analysing the cellular processes underlying these conditions.

Study on relationship between pain and higher brain functions

University of Texas Medical Branch at Galveston professor Volker Neugebauer has been awarded a four-year, $1.36 million grant by the National Institute of Neurological Disorders and Stroke to conduct an innovative study of the relationship between pain and parts of the brain associated with cognitive thought and emotional response.
