Reassessing How Light Impacts Behavior
Northwestern Medicine investigators have found that a small subset of cells in the retina inhibit the communication of light signals from the eyes to the brain, impacting how light affects daily activity and how the pupils constrict to light.

Unexpected Diversity in Neuronal Spine Projections
Small projections of dendritic spines known as spinules are unexpectedly dynamic, while a stable subgroup may form multi-synaptic spine connections, according to the first detailed study of their behavior.

Muscle Synergy Helps Maintain Joint Balance
The nervous system groups sets of muscles producing opposing forces on joints, firing the muscles simultaneously to ensure joints aren’t stressed or injured by unbalanced forces, according to a recent study.
