Ancient Origins of Speed Control During Movement

Movement in animals is complex. Little has been known about how spinal inhibitory interneurons work to silence other neurons and related muscle groups in coordination with the active muscle groups ...

Ingestible Capsule That Could Help Demystify the Gut-Brain Axis

A team of experts from engineering, neuroscience, applied microbiology, and physics has been making headway on building a platform that can monitor and model the real-time processing of gut ...

Nerves That Sense Touch May Play Role in Autism

Autism is considered a disorder of the brain. But a new study suggests that the peripheral nervous system, the nerves that control our sense of touch, pain and other sensations, may play a role as ...

Scientists Identify Sensor Protein That Underlies Bladder Control

Scientists have found that the main sensor protein enabling our sense of touch also underlies the feeling of having a full bladder and makes normal bladder function possible. The discovery marks a ...

Single Brain Region Links Depression and Anxiety, Heart Disease, and Treatment Sensitivity

Over-activity in a single brain region called the subgenual anterior cingulate cortex (sgACC) underlies several key symptoms of mood and anxiety disorders, but an antidepressant only successfully ...

Gut Hormone Blocks Brain Cell Formation and Is Linked to Parkinson's Dementia

A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a research team has discovered. It could help pave the way for new drugs to treat dementia in patients with ...

Trigger That Leads to Faster Nerve Healing

Damaged nerves regenerate faster when protein clusters are broken apart, releasing mRNAs that can be used to rebuild the nerve. Scientists have found the trigger that could be used to accelerate ...

New Mechanism Affecting Nerve Impulses Discovered

Researchers have discovered a new mechanism by which substances can open a certain type of ion channel and in this way regulate nerve impulses. The study identifies a large group of substances that ...

Taking the STING out of MND

Researchers are working towards a potential treatment to slow the progression of motor neuron disease (MND). The research team have uncovered how inflammation in MND is triggered. Pinpointing the ...

A Hydrogel That Could Help Repair Damaged Nerves

Injuries to peripheral nerves -- tissues that transmit bioelectrical signals from the brain to the rest of the body -- often result in chronic pain, neurologic disorders, paralysis or disability. ...

Study Finds Odor-Sensing Neuron Regeneration Process Is Adaptive

Results show that diminished odor stimulation reduces the number of newly-generated neurons that express particular odorant receptors, indicating a selective alteration in the neurogenesis of these ...

Evidence of Alzheimer's, Parkinson's and MND in Brains of Young People Exposed to Dirty Air

After examining the brainstems of 186 young Mexico City residents aged between 11 months and 27 years of age, researchers, found markers not only of Alzheimer's disease, but also of ...

Millimeter-Precision Drug Delivery to the Brain

Focused ultrasound waves help researchers to deliver drugs to the brain with pinpoint accuracy, in other words only to where their effect is desired. This method is set to enable treatment of ...

Finding Right Drug Balance for Parkinson's Patients

Parkinson's disease is most commonly treated with levodopa, but the benefits wear off as the disease progresses and high doses can result in dyskinesia, which are involuntary and uncontrollable ...

Spinal Cord Stimulation Reduces Pain and Motor Symptoms in Parkinson's Disease Patients

A team of researchers reports that spinal cord stimulation (SCS) measurably decreased pain and reduced motor symptoms of Parkinson's disease, both as a singular therapy and as a 'salvage ...

Tone of Voice Matters in Neuronal Communication

Neuronal communication is so fast, and at such a small scale, that it is exceedingly difficult to explain precisely how it occurs. An observation enabled by a custom imaging system, has led to a ...

Identical Signs of Brain Damage in Sleep Apnea and Alzheimer's

New research shows damage in the brain starts in the same place and spreads in the same way in sleep apnea, as in Alzheimer's disease. The study is the first to find Alzheimer's-like ...

Stem Cells Can Repair Parkinson's-Damaged Circuits in Mouse Brains

Researchers demonstrated a proof-of-concept stem cell treatment in a mouse model of Parkinson's disease. They found that neurons derived from stem cells can integrate well into the correct ...

160 Genes Linked to Brain Shrinkage in Study of 45,000 Adults

An analysis conducted in 45,000 adults mainly of European ancestry associated 160 genes with brain shrinkage seen on ...

Nerve Cells Let Others 'Listen In'

How many 'listeners' a nerve cell has in the brain is strictly regulated. In the environment of learning neurons, certain processes are set in motion that make signal transmission less ...

Decreased Protein Degradation in Cerebellum Leads to Motor Dysfunction

Researchers have developed an animal model that reproduces motor dysfunction and cerebellar neurodegeneration similar to that in spinocerebellar ataxia (SCA) by inhibiting chaperone-mediated ...

Fructose Made in the Brain Could Be a Mechanism Driving Alzheimer's Disease, Researchers Propose

New research proposes that Alzheimer's disease may be driven by the overactivation of fructose made in the brain. The study outlined the hypothesis that Alzheimer's is a modern disease ...

Faulty Transportation of Messenger RNA Is the Culprit in ALS

Researchers have discovered a function for the protein missing in many types of ALS and FTLD, two neurodegenerative diseases. In neurons, the protein TDP-43 bound to messenger RNA that codes for ...

Sport and Memory Go Hand in Hand

If sport is good for the body, it also seems to be good for the brain. By evaluating memory performance following a sport session, neuroscientists demonstrate that an intensive physical exercise ...
