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...
Research sheds new light on how the brain forms and recalls memories
During memory formation, the directional coupling between the neocortex and hippocampus alters. Decreased power in brain oscillations in the neocortex preceded and predicted increased power in the hippocampus. The reverse occurs during memory retrieval.... Read More...
Blue Brain finds how neurons in the mouse neocortex form billions of synaptic connections
Scientists generated statistical instances of the micro-connectome, containing over 10 million neurons. The model spans five orders of magnitude and contains 88 billion synaptic connections.... Read More...
Machine learning algorithm can’t distinguish these lab mini-brains from preemie babies
Machine learning is unable to tell the difference in brain activity between a lab-grown mini-brain and that of a preterm infant who has reached full-term.... Read More...
Brain network activity can improve in epilepsy patients after surgery
Functional connectivity problems associated with temporal lobe epilepsy appear to improve after surgery. ... Read More...
Brain changes in autism traced to specific cell types
Studying brain tissue samples from people with ASD revealed a common set of alterations in genes associated with synaptic communication between neurons. The changes were identified mainly in neurons in the uppermost layers of the neocortex. ... Read More...
Blue Brain solves a century-old neuroscience problem
A mathematical algorithm developed by the Blue Brain Project can objectively classify different shapes of neurons in the brain. The algorithm has already helped researchers objectively identify 17 types of pyramidal neurons in the somatosensory cortex of a rat.... Read More...
Our brains may ripple before remembering
Coupled ripples between the medial temporal lobe and temporal cortex are enhanced prior to successful memory retrieval. ... Read More...
Brain Wave Stimulation May Improve Alzheimer’s Symptoms
Multisensory gamma wave stimulation improves recognition and spatial memory, in addition to reducing amyloid in the auditory cortex and hippocampal CA1 areas of mice. Findings suggest such sensory stimulation boosts hippocampal function and reduces Alzheimer's linked pathologies throughout the neocortex.... Read More...
MRI Scans Reveal How the Brain Protects Memories
A new MRI study reveals the neocortex and hippocampus are involved in mediating memory interference. ... Read More...
Building a Bigger Brain
ARHGAP11B, a gene unique to humans and active in the cerebral cortex, causes enlargement of the ferret neocortex when introduced during development. ... Read More...
