Understanding the origins of spontaneous neural activity

A new study, published in Nature Communications this week, led by Jake Gavenas PhD, while he was a PhD student at the Brain Institute at Chapman University, and co-authored by two faculty members of the Brain Institute, Uri Maoz and Aaron Schurger, examines how the brain initiates spontaneous actions. In addition to demonstrating how spontaneous action emerges without environmental input, this study has implications for the origins of slow ramping of neural activity before movement onset - a commonly-observed but poorly understood phenomenon.
