Sons of cocaine-using fathers have profound memory impairments

Fathers who use cocaine at the time of conceiving a child may be putting their sons at risk of learning disabilities and memory loss. The researchers say the findings reveal that drug abuse by fathers — separate from the well-established effects of co…

Studies show that the cerebellum is crucial to understanding vulnerability to drug addiction

The cerebellum, contrary to what was thought, fulfils functions that go beyond the motor sphere and can be co-responsible for the brain alterations associated with addictive consumption of drugs, research shows. The findings would represent a step forw…

Tired teens 4.5 times more likely to commit crimes as adults

Teenagers who experience sleep problems and exhibit anti-social behavior are more likely to commit violent crimes as adults, new research concludes.

Researchers uncover brain circuitry central to reward-seeking behavior

Scientists have found that as mice learn to associate a particular sound with a rewarding sugary drink, one set of prefrontal neurons becomes more active and promotes reward-seeking behavior while other prefrontal neurons are silenced, and those neuron…

Brain-machine interfaces: Bidirectional communication at last

A prosthetic limb controlled by brain activity can partially recover the lost motor function. Neuroscientists asked whether it was possible to transmit the missing sensation back to the brain by stimulating neural activity in the cortex. They discovere…

Scientists survey the state of sleep science

Sleep remains an enduring mystery with major clinical relevance, according to a a recent review. In recent decades, new technologies have allowed neuroscientists to identify multiple brain circuits that govern the sleep/wake cycle, as well as the facto…

Itch neurons play a role in managing pain

There are neurons in your skin that are wired to sense itchy things. These neurons are separate from the ones that detect pain, and yet, chemical-induced itch is often accompanied by mild pain such as burning and stinging sensations. But when it comes …

Superfluid is now helping brain surgeons

A superfluid, which resembles brain tissue, makes ultrasound images easier to interpret during an operation. This will make it easier for surgeons to remove brain tumors more accurately, say researchers.

Precise inactivation of neural messenger receptor wipes out fear memory in mice

Research combines antibody precision with toxic oxygen burst to inactivate neural protein and temporarily abolish fear memory in mice.

Depression puts psoriasis patients at significantly greater risk of psoriatic arthritis

Psoriasis is a lifelong disease that is associated with significant cosmetic and physical disability and puts patients at increased risk for many major medical disorders. A multidisciplinary team of researchers has found that psoriasis patients who dev…
