New technology will create brain wiring diagrams

The human brain is composed of billions of neurons wired together in intricate webs and communicating through electrical pulses and chemical signals. Although neuroscientists have made progress in understanding the brain's ...

Autism-linked gene stunts developing dendrites

Increased expression of a gene linked to autism spectrum disorders (ASDs) leads to a remodeling of dendrites during brain development, according to a new study conducted in cultured neurons and an ASD mouse model published ...

Star-shaped brain cells orchestrate neural connections

Brains are made of more than a tangled net of neurons. Star-like cells called astrocytes diligently fill in the gaps between neural nets, each wrapping itself around thousands of neuronal connections called synapses. This ...

Mice offer a window into sleep's role in memory

Sleep provides essential support for learning and memory, but scientists do not fully understand how that process works on a molecular level. What happens to synapses, the connections between neurons, during sleep that helps ...

'Recycling protein' shown to affect learning and memory in mice

Learning and memory depend on cells' ability to strengthen and weaken circuits in the brain. Now, researchers at Johns Hopkins Medicine report that a protein involved in recycling other cell proteins plays an important role ...

New mech­an­ism un­der­ly­ing epi­lepsy found

Prolonged epileptic seizures may cause serious problems that will continue for the rest of a patient's life. As a result of a seizure, neural connections of the brain may be rewired in an incorrect way. This may result in ...

Adverse effects of cannabis scientifically verified

Researchers have clarified important mechanisms involved in the formation of neural circuits in the brain. This group also discovered that delta-9-tetrahydrocannabinol (THC), a psychoactive substance also found in cannabis, ...
