BiPOLES is an optogenetic tool that allows bidirectional control of neuronal activity using two different light colors, enabling both excitation and inhibition of the same neurons in a single experiment.

The paper shows that cFos expression in the dentate gyrus changes daily and does not stabilize with spatial memory, yet neurons from early training days still influence later performance.

This study shows that multi-frequency tACS has lasting effects on neural synchrony and audiovisual responses in anesthetized ferrets.

This study shows that intermediate/ventral hippocampal glutamatergic neurons drive prefrontal oscillations in neonatal mice through direct axonal projections and light stimulation.

The paper identifies pyramidal neurons in the prefrontal cortex as key elements causing abnormal circuit function in a mouse model of mental illness and shows that microglia inhibition rescues these deficits.
