Parkinson’s disease

New Cause of Parkinson’s Disease Found

A study led by Prof. Daesoo Kim of KAIST has overturned 30 years of consensus on the cause of Parkinson’s disease. The team showed that...

Researchers Discover Neuronal Targets That Restore Movement in Model of Parkinson’s...

Researchers working in the lab of Carnegie Mellon University neuroscientist Aryn Gittis have identified two groups of neurons that can be turned on and...
optical brain probes

Shining Light Deep into the Brain

To map the inner workings of the living brain, scientists have long employed various types of brain probes, beginning with simple electrical wires and...
prefrontal cortex

Traffic Light in the Brain

Whether the brain responds to an external stimulus or not depends significantly on the balance between areas of excitation and inhibition in the prefrontal...

Tailored Carbon Could Help Treating Neurological Diseases

Tomi Laurila's research topic has many quirky names. "Nanodiamond, nanohorn, nano-onion...," lists off the Aalto University Professor, recounting the many nano-shapes of carbon. Laurila is...
cerebral cortex

Neurons Form Synapse Clusters

The cerebral cortex resembles a vast switchboard. Countless lines carrying information about the environment, for example from the sensory organs, converge in the cerebral...

Brighter prospects for chronic pain

Researchers use optogenetics to produce pain relief by shutting off neurons with light
tumors

Researchers Prevent, Normalize Tumors Using Light to Control Cell Electric Signals

Tufts biologists apply optogenetics to cancer for the first time
bioelectric

Faulty bioelectric signal responsible for facial defects caused by rare genetic...

Discovery may shed light on fetal alcohol syndrome, other conditions
opioid

Opioid withdrawal neural pathway discovered

Stanford researchers manipulated the brains of morphine-addicted mice and allowed the animals to overcome withdrawal symptoms. The finding could offer a new approach to quieting symptoms that often lead to recurring drug use.
sugar

Yale team deciphers sugar’s siren song

Sugar’s sweetness and calorie content combine to give it lethal power to destroy diets, many scientists have assumed.  However, new study by Yale University...

Red means ‘go’ to therapeutic viruses

Rice University scientists use light to switch viral activity and deliver cargoes to cells 

Researchers Find Way to Control Heart Waves With Light

Electrical waves regulate the rhythm of the heartbeat, and when those signals go awry, the result is a potentially fatal arrhythmia. Now, a team...

Penn Medicine Researchers Discover Hidden Brain Pathways Crucial to Communication

Being able to understand speech is essential to our evolution as humans. Hearing lets us perceive the same word even when spoken at different...

How the brain controls sleep

Sleep is usually considered an all-or-nothing state: The brain is either entirely awake or entirely asleep. However, MIT neuroscientists have discovered a brain circuit...
