‘Superagers’ over 80 have the memory and brain connectivity of twenty-somethings
Both the default mode network and salience network in superagers had stronger connectivity than typical older adults and similar connectivity as younger adults. Superagers performed similarly to young adults and better than typical older adults in recognition and episodic memory tasks. ... 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...
How memories form and fade
Stable memories are encoded by teams of neurons firing in synchrony, providing redundancy that enables the memory to persist over time.... Read More...
Finding the brain’s compass
Researchers have identified a neural network in mice that transfers high dimensional complex information about the environment to a simple abstract object in the brain.... Read More...
Hypothalamus pathway drives defense behaviors
A newly discovered pathway that links the hypothalamus and midbrain drives innate defense behaviors. The findings could have implications for developing therapies for anxiety disorders.... Read More...
Newly discovered neural pathway processes acute light to affect sleep
Study challenges the widely accepted belief that all light information is relayed through the suprachiasmatic nucleus, which synchronizes the circadian rhythm.... Read More...
Research Identifies New Pathways for Sensory Learning in the Brain
Automated robotic technology allows researchers to identify new pathways activated when the brain rewires circuits in response to experience.... Read More...
Researchers link aging with changes in brain networks related to cognition
As people age, the brain networks associated with cognition become less efficient at information transfer and more vulnerable to disturbance.... Read More...
