🚨 New paper alert! 🚨(1/6)

Excited to share our work, out now in Science Advances

We show that a rapid norepinephrine surge along a brainstem pathway (LC→PRN) is a key driver of sound-evoked awakenings
www.science.org/doi/10.1126/...

An early surge of norepinephrine along brainstem pathways drives sensory-evoked awakening

The locus coeruleus has a specialized pathway to the brainstem that controls sound-evoked awakening from sleep.

Rate and noise in human amygdala drive increased exploration in aversive learning:

Congratulations to my colleagues Rony Paz, Ido Strauss, Firas Fahoum for landing this exciting paper in Nature!

Rate and noise in human amygdala drive increased exploration in aversive learning

Nature - Human exploration is driven by two distinct neural mechanisms, a valence-independent rate signal and a valence-dependent global noise signal.

Slow waves during sleep are fundamental for neural homeostasis and are impaired in neurodegenerative diseases. But what about sleep-like slow waves during wakefulness? Are these slow waves altered in Parkinson's disease? Are these slow waves uncovering psychosis?
