Sense of Touch Reproduced Through Prosthetic Hand
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.
Preclinical Study Shows Heroin Vaccine Blocks Relapse
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.
Gone, But Not Forgotten
Researchers describe in detail the underlying neurobiology of the “world’s second most famous amnesiac”, EP, who suffered profound memory loss after damage to key portions of his brain.
Scientists Reverse Memory Loss in Animal Brain Cells
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.
Bad Decisions Arise from Faulty Information, Not Faulty Brain Circuits
Researchers conclude that poor quality information is to blame for bad decision making, not faults with neural processing.
Tiny Wireless Device Shines Light on Mouse Brain, Generating Reward
Researchers implant optogenetic electronic device into mouse brains, stimulating dopamine producing neurons by emitting light.
Reliability of Neuroscience Research Questioned
New research questions the reliability of neuroscience studies, concluding that results could be misleading due to low statistical power.
Sensational Success in Patients with Major Depression Using Deep Brain Stimulation
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.
Breakthrough in Neuroscience Could Help Re-Wire Appetite Control
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.
Motor Skills Research Nets Good News for Middle-Aged
Researchers discover a slight decline in fine motor skills associated with aging, with a marked drop in ability for those aged 64 and older.
