Learning is something everyone does daily—mastering new skills at work, remembering song lyrics, or following directions to new places. But behind these everyday tasks lies a complex biological ...

Researchers used positron emission tomography, or PET, brain imaging on 32 people with AUD and 29 controls. They found 11% lower synaptic density in the frontal cortex, striatum, and hippocampus of ...

Glutamate receptors, including AMPA and NMDA subtypes, are pivotal mediators of excitatory transmission and plasticity across the mammalian central nervous system. Their regulation, which involves ...

In the brain, synaptic plasticity - the ability to change neuronal connections over time - is fundamental to learning and memory. Traditionally, science has focused on nerve cells and their synapses.

Neurons are important, but they are not everything. Indeed, it is "cartilage," in the form of clusters of extracellular matrix molecules called chondroitin sulfates, located in the outside nerve cells ...

Scientists disclose how mitochondria control tissue rejuvenation and synaptic plasticity in the adult mouse brain. Nerve cells (neurons) are amongst the most complex cell types in our body. They ...

In December of 1993, former World Boxing Champion John Famechon (who had sustained severe incapacitating brain injuries in August 1991) began a new, complex multi-movement therapy and rehabilitation ...
