Antibodies in the brain trigger epilepsy

Certain forms of epilepsy are accompanied by inflammation of important brain regions. Researchers at the University of Bonn have now identified a mechanism that explains this link. Their results may also pave the way to new ...

A next-gen EEG could bring back lost brain function

A device under development at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University could help bring back lost brain function by measuring how the brain responds to therapies that stimulate ...

Heavy alcohol use in adolescence alters brain electrical activity

Long-term heavy use of alcohol in adolescence alters cortical excitability and functional connectivity in the brain, according to a new study from the University of Eastern Finland and Kuopio University Hospital. These alterations ...

Neuroscience

Evolving deep brain stimulation patterns

Duke University biomedical engineers have used computers to "evolve" more effective patterns of electric shocks delivered deep within the brain to treat Parkinson's disease symptoms.

Ophthalmology

Smart microchips may optimise human vision

To date, chip-based retinal implants have only permitted a rudimentary restoration of vision. However, modifying the electrical signals emitted by the implants could change that. This is the conclusion of the initial published ...

Neuroscience

Researcher observes active role of auditory neurons

Cells in the brainstem that underlie sound localization, compare signals at the two ears and can pause while doing so. This was shown by researchers at the Laboratory for Auditory Neurophysiology in Leuven, who were the first ...

Neuroscience

The brain's electrical alphabet

The brain's alphabet is a mix of rate and precise timing of electrical pulses: the observation was made by researchers at the International School for Advanced Studies (SISSA) of Trieste and the Italian Institute of Technology ...

Neuroscience

Memory in silent neurons

When we learn, we associate a sensory experience either with other stimuli or with a certain type of behavior. The neurons in the cerebral cortex that transmit the information modify the synaptic connections that they have ...
