Disrupted networks link overlapping cognitive deficits in psychiatric disorders

Psychiatric disorders share common alterations of functional connectivity between three core brain networks involved in cognition, according to a meta-analysis.

New insight into the process of generation of new neurons in the adult brain

Researchers have discovered a novel and unexpected function of nestin, the best known marker of neural stem cells.

Controlling neurons with light — but without wires or batteries

In optogenetics, scientists use light to turn groups of neurons in the brain on or off. New research demonstrates a new optogenetics method that eliminates the need for bulky optical fibers, gives researchers more precise control of the light’s intensi…

‘A way cool way to be’: Study offers new insights into children with autism

In the first study of its kind, a team of researchers was able to perform functional MRIs of a group of children with autism whose IQs averaged 54. The scans offer a glimpse into what’s happening in their brains.

How does the brain learn by talking to itself?

One of the greatest challenges of systems neuroscience is to explain how synaptic connections change to support adaptive behaviours. Neuroscientists have previously showed that synaptic learning mechanisms in the brain’s cortex are dependent on feedbac…

Risk of developing depression and anxiety is higher in those with cerebral palsy

Adults with cerebral palsy have a higher risk of developing depression and anxiety than their peers without the condition, a new study reports.

Two possible new ways to treat silent seizures in children

A recent study characterizes silent seizures in a mouse model of Dravet syndrome and identifies a new brain area that could be targeted to stop them.

Wireless ‘pacemaker for the brain’ could offer new treatment for neurological disorders

A new neurostimulator can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson’s.

Thriving on teamwork: New research shows how brain cells filter information in groups

For decades, scientists studying the visual system thought that individual brain cells, called neurons, operate as filters. Some neurons would prefer coarse details of the visual scene and ignore fine details, while others would do the opposite. Every …

Smelling in tiny houses: How ciliary electric currents keep olfaction reliable

Scientists have used a combination of mathematical modeling, electrophysiology, and computer simulations to explain how cells communicate effectively in highly constricted spaces such as the olfactory cilia, where odor detection takes place. The findin…
