Credit: University of Michigan A new study finds that patients with fibromyalgia have brain networks primed for rapid, global responses to minor changes. This abnormal hypersensitivity, called explosive synchronization (ES), can be seen in other network phenomena across nature. Researchers from the University of Michigan and Pohang University of Science and Technology in South Korea […]Continue Reading ...
(HealthDay)—C7 nerve transfer is beneficial for patients with unilateral arm paralysis for more than five years, according to a study published online Dec. 20 in the New England Journal of Medicine. Mou-Xiong Zheng, M.D., Ph.D., from Fudan University in Shanghai, and colleagues randomized 36 patients with unilateral spastic arm paralysis for more than five years […]Continue Reading ...
Examples of movements of zebrafish larvae. Each movement is represented by the tail’s position through time. Colors mark the passage of time (blue at the start of the movement and red at the end).

Assessing grip strength can show flaws in the brain’s attention-control. Credit: Imperial College London An inability to focus the brain on tasks may partially explain why paralysis commonly occurs in people following a stroke, according to a news study. Patients who have suffered a stroke – where the blood flow to the brain is interrupted […]Continue Reading ...
Credit: CC0 Public Domain All things must come to an end. This is particularly true for neurons, especially the extensions called axons that transmit electrochemical signals to other nerve cells. Without controlled termination of individual neuron growth, the efficient and accurate construction of a nervous system is in serious jeopardy. Scientists from the Florida campus […]Continue Reading ...
The image shows the locus coeruleus, which drives neuronal circuits of the hippocampus and enables novel contextual memory. The red staining shows norepinephrine transporter (NET)-positive cells, indicating the locus coeruleus. The green staining shows adeno-associated virus (AAV)-mediated expressions of light-sensitive inhibitory opsin, archaerhodopsin (Arch). The blue staining shows all cells in the brain stem.

‘Tis the season for choirs to raise their voices in holiday song. A new Annals of Neurology study shows that there is a high frequency of tics in an extremely highly achieving group of pre-pubertal singers. 35% of 40 young singers in the Boys Choir exhibited tics during a public concert of Bach’s Christmas Oratorio. […]Continue Reading ...
Very preterm born neonates can be exposed to hundreds of skin breaking procedures during the first weeks of life in the neonatal intensive care unit. Thalamic growth, obtained from volumetric segmentations (red) on magnetic resonance images (sagittal views) at postmenstrual ages of 32 and 40 weeks, was reduced in neonates receiving a high number of […]Continue Reading ...
Credit: CC0 Public Domain A new and relatively simple technique for mapping the wiring of the brain has shown a correlation between how well connected an individual’s brain regions are and their intelligence, say researchers at the University of Cambridge. In recent years, there has been a concerted effort among scientists to map the connections […]Continue Reading ...
People in the study who walked more than 4,000 steps each day had superior performance in attention, information-processing speed and executive functioning. Credit: Ryan Johnson/Flickr Walking more than 4,000 steps a day can improve attention and mental skills in adults 60 and older, according to UCLA research published December 12 in a preprint edition of […]Continue Reading ...
A study from a team of Massachusetts General Hospital (MGH) investigators points toward a potential strategy for treating X-linked disorders – those caused by mutations in the X chromosome – in females. Their report published online in PNAS Early Edition, describes how a dual-modality approach was able to reactivate the inactive X chromosome in mouse […]Continue Reading ...
For people with brain disorders, whether from injury or disease, rehabilitation is a complex process. Neurosexuality is an emerging area of study and practice that focuses on the relationships between brain and sexual function in individuals with and without neurological disorders. Experts on the subject, reporting in NeuroRehabilitation, discuss how sexuality can affect neurorehabilitation in […]Continue Reading ...
The research findings of Jacqueline Snow (left) and Michael Gomez, a graduate student in her lab at the University of Nevada, Reno, show that real, graspable objects hold more interest for humans than images of objects.

Typically, the right IFG stops the flow of speech, whereas the left one supports it. In people who stutter, these two areas are conversely activated: The right IFG is overactive and shows tightened connections with the frontal aslant tract (FAT), which is a sign of a strengthened movement inhibition. This interrupts the flow of speech […]Continue Reading ...
Real-time data downloaded from a patient’s wireless implant reveal the deep brain waves that support spatial navigation and memory. Credit: University of California, Los Angeles UCLA neuroscientists are the first to show that rhythmic waves in the brain called theta oscillations happen more often when someone is navigating an unfamiliar environment, and that the more […]Continue Reading ...
