Neurological signals from the spinal cord surprise scientists

A new study challenges existing theories about spinal cord neurons. New findings suggest neurological signals originate from a major, scattered network of cells that send signals to only a few other neurons.

‘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.
