USC researchers built artificial neurons that replicate real brain processes using ion-based diffusive memristors. These devices emulate how neurons use chemicals to transmit and process signals, ...

This important study combines optogenetic manipulations and wide-field imaging to show that the retrosplenial cortex controls behavioral responses to whisker deflection in a context-dependent manner.

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...
