Researchers have developed a fiber-optic, two-photon optogenetic simulator which can be used to stimulate a light sensitive protein introduced into neurons and living cells in the brain. The researchers suggest this technology would be a useful tool for the BRAIN mapping initiative.
A drug developed by scientists at the Salk Institute for Biological Studies, known as J147, reverses memory deficits and slows Alzheimer’s disease in aged mice following short-term treatment.
A new study points to a correlation between suicide rates and environmental pollution caused by emissions from coal-fired electricity plants in North Carolina.
Researchers discover evidence of altered circadian rhythms and disrupted brain gene orchestration in patients with major depression.
Researchers have successfully tested a new vaccine in primates to battle cocaine addiction. Using neuroimaging techniques, they demonstrated the vaccine prevents cocaine from reaching the brain and producing a dopamine induced high. Human trials could begin within the next year.
Artificial sensors in a prosthetic hand allows rhesus macaques to sense tactile stimulus, according to a new study. A similar device could be used in human trials within the next year, researchers hope.
Scientists reported successful preclinical tests in rats of a new vaccine against heroin addiction. The vaccine targets heroin and its psychoactive breakdown products in the bloodstream, blocking relapse.
Using the nerve cells of sea snails, researchers reverse memory loss by determining when cells were primed for learning. Retraining cells with the use of an optimized training schedule helped compensate for memory loss.
Researchers conclude that poor quality information is to blame for bad decision making, not faults with neural processing.
