Reconstructing spoken words as processed in nonhuman primate brains
Using artificial intelligence and brain-computer interface technology, researchers reconstructed English words from neural signals recorded from the brains of non-human primates.... Read More...
Individuals are swayed by their peers, leading to more severe punishments
Peer pressure can shift an individual's punitive preference across a variety of contexts. Groups induce conformity by forcing less caution and more impulsivity in individuals, and by amplifying the value of punishment. ... Read More...
Neuron type that acts as brain’s metronome discovered
A distinct fast-spiking interneuron subtype mediates perceptually relevant brain oscillations, independently of local field potential and sensory drive.... Read More...
Unexpectedly, big wins improve two kinds of memory
Unexpected rewards boost memories of specific events. The findings may have implications for treating memory problems associated with depression. ... Read More...
HIV Drug Could Treat Alzheimer’s and Age Associated Disorders
Researchers report a drug commonly used to help treat HIV can significantly reduce age related inflammation in mice. The study suggests the drug could hold promise for treating age related disorders including Alzheimer's disease, type 2 diabetes and Parkinson's disease.... Read More...
Gut Microbiome Regulates Intestinal Immune System
A new study reveals the gut microbiome regulates the immune system. Vitamin A is key to allowing the symbiotic relationship, researchers report. ... Read More...
Early Life Stress Hinders Neuron Development, Causing Attention Disorders: Mouse Study
Female mice who experienced early life stress developed problems and had fewer neurons in areas of the brain responsible for regulating emotions and making sense of rules, researchers report.... Read More...
Brain Computer Interface Enables People with Paralysis to Control Tablets
Researchers report a brain computer interface can enable those with paralysis to directly operate tablet technology just by thinking about cursor movements and clicks. ... Read More...
Just a Few Drinks Can Change How Memories Are Formed
Researchers report alcohol hijacks a conserved memory pathway in the brain and alters protein expressed in neurons, forming craving that fuel addiction.... Read More...
Teaching Computers to See Optical Illusions
Researchers have created a deep learning algorithm that can be tricked by optical illusions, just like humans. The findings shed new light on the human visual system and may help improve artificial vision.... Read More...
Visual Perceptual Skills Are Updated By Processes Similar to Memory Reconsolidation
Researchers report our ability to identify and categorize visual information is an active process similar to memory stabilization.... Read More...
