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.
Researchers implant optogenetic electronic device into mouse brains, stimulating dopamine producing neurons by emitting light.
Researchers implanted pacemaker electrodes into the medial forebrain bundle of patients suffering from major depression and performed deep brain stimulation. In a matter of days, in six out of seven patients, symptoms such as anxiety, despondence, listlessness and joylessness had improved considerably.
Researchers discover a population of cells, called tanycytes, are capable of generating new appetite regulating neurons in the brains of both young and adult rodents. The discovery could offer new avenues for tackling obesity.
Researchers discover a slight decline in fine motor skills associated with aging, with a marked drop in ability for those aged 64 and older.
