Mapping scattered pictures, in the corners of our mind

By GREGORY ZELLER // Straight from the hippocampus (and the horse’s mouth) comes a new research paper in the journal Science, highlighting landmark innovations in human brain mapping. Published Aug. 16 by the peer-reviewed academic journal of the American Association for the Advancement of Science, “Hippocampal Sharp-Wave Ripples Linked to Visual Episodic Recollection in Humans” carries a heavy title but a simple synopsis: real-time mapping of specific brain neurons that fire when humans form visual…


NIH triples up on Feinstein Institute brain specialist

Three brain-focused research projects at the Feinstein Institute for Medical Research will benefit from more than $1 million in federal funding. The Manhasset-based Feinstein Institute, R&D arm of the Northwell Health system, announced Thursday that the NIH’s Brain Research Through Advancing Innovative Neurotechnologies initiative has allotted two stipends to support projects led by Feinstein Associate Professor Ashesh Mehta, Northwell’s director of epilepsy surgery and head of the institute’s Laboratory of Human Brain Mapping. Mehta’s work…


With VNS, additional strides in controlling epilepsy

By GREGORY ZELLER // Dr. Ashesh Mehta, head of North Shore-LIJ’s epilepsy care center, performed two surgeries on July 24, one fairly routine, one a bit less so. For now, anyway. Both involved VNS, or electrical stimulation of the vagus nerves, the long bundle of fibers connecting the brain and abdomen.
