A CRISPR-based system that reverses epigenetic changes caused by adolescent binge drinking reduces adult addiction-like behaviors in rats, a study finds, suggesting that an epigenomic approach could someday help treat people with alcohol use disorder.
The University of Guelph neuroscientist is scoping out the brain regions and genes that change as a consequence of pain that lasts for months or even years.
So-called mossy fiber synapses in the hippocampus can meter the amount of neurotransmitter they receive by sending glutamate against the usual direction of synaptic flow.
In an unexpected twist in neuroscience dogma, the cells on the receiving end of neurotransmission appear to be able to release glutamate to regulate the transmitting cell’s activity.
Synapses in the mouse neocortex can release multiple packages of neurotransmitters, suggesting that connection strength is more flexible than previously thought.
In mice, injected fragments of a naturally occurring protein boost memory in young and old animals and improve cognition and mobility in a model of neurodegenerative disease.
The UCLA neurobiologist uses computational modeling, in vitro electrophysiology, and human psychophysics experiments to explore how neurons and the brain as a whole perceive and respond to time.
