Scientists Identify Craving Cells in Human Brain That Drive Compulsive Eating

Dr. Halpern's team has identified specific neurons in the nucleus accumbens that fire in patterns corresponding to cravings and obsessions in patients with OCD and binge eating disorder. Similar to how they can hear tremor cells that match the frequency of physical tremors, they've detected electrical signatures of psychological cravings, potentially opening new treatment pathways for addiction and eating disorders.

Neurosurgeon Reveals Deep Brain Stimulation Can Immediately Eliminate 20-Year Tremors

Dr. Casey Halpern, chief of stereotactic functional neurosurgery at Penn Medicine, described the dramatic immediate effect of deep brain stimulation on patients with chronic tremors. The procedure involves placing electrodes in specific brain regions and delivering electrical stimulation that can instantly stop tremors that have persisted for decades, demonstrating the power of precise electrical modulation of motor circuits.

Surgeons Can Destroy Brain Tissue Without Observable Side Effects, Neurosurgeon Claims

Dr. Halpern revealed that neurosurgeons can safely ablate small regions of brain tissue—3-4 millimeters in size—with apparently no detectable functional consequences. He compared certain brain regions to an appendix, suggesting some areas may be safe to destroy entirely. This challenges common assumptions about brain tissue being uniformly critical and raises questions about brain redundancy.

Binge Eating Patients Cannot Stop Even Under Video Surveillance in Lab

In controlled laboratory experiments at Penn Medicine, researchers found that patients with severe binge eating disorder continue to binge despite full awareness they are being watched and recorded. Psychiatrists deliberately provoke moods associated with binges while monitoring brain activity, revealing that the most severe cases involve complete loss of volitional control regardless of conscious awareness.

FDA-Approved Ultrasound Can Now Ablate Brain Tissue With No Incision

Dr. Halpern revealed that MRI-guided focused ultrasound is now FDA-approved and being used routinely to ablate brain tissue for tremor without any surgical incision. The technology can precisely heat and destroy targeted brain regions non-invasively. While currently approved only for tremor, researchers are exploring its use for psychiatric conditions, addiction, and eating disorders, potentially revolutionizing brain surgery.
