a neural circuit taxonomy for depression and anxiety
A team led by neurologists at Beth Israel Deaconess Medical Center (BIDMC) has pinpointed the regions of the brain that may play a role maintaining consciousness. “For the first time, we have found a connection between the brainstem region involved in arousal and regions involved in awareness, 2 prerequisites for consciousness,” said Michael D. Fox, MD, PhD, Director of the Laboratory for Brain Network Imaging and Modulation and the Associate Director of the Berenson-Allen Center for Noninvasive Brain Stimulation at BIDMC.
Arousal is likely regulated by the brainstem, responsible for the sleep/wake cycle and cardiac/ respiratory rates. Awareness has long been thought to reside in the cortex...
