Temperature Plays a Role in Brain Activity Related to Episodic Memory and Planning

Article title: Brain temperature affects quantitative features of hippocampal sharp wave ripples Authors: Peter C. Petersen, Mihály Vöröslakos, György Buzsáki From the authors: “Here, we show that features of hippocampal ripples, including the rate of occurrence, peak frequency, and duration…

Scientists See Signs of Traumatic Brain Injury in Headbutting Muskox

Scientists at the Icahn School of Medicine at Mount Sinai saw for the first time hallmarks of concussions and other head trauma in the brains of deceased headbutting animals—muskoxen and bighorn sheep. The results published in the journal Acta Neuropathologica may contradict the commonly-held belief that ramming animals do not suffer brain injuries and support the notion that studies on animals with brains evolutionarily similar to those of humans may help researchers understand and reduce traumatic brain injuries.

University of Minnesota technology allows amputees to control a robotic arm with their mind

A team of biomedical engineering researchers and industry collaborators have developed a way to tap into a patient’s brain signals through a neural chip implanted in the arm, effectively reading the patient’s mind and opening the door for less invasive alternatives to brain surgeries.

EMT Receives Life-Saving Stroke Care from JFK University Medical Center Colleagues

January 5, 2022 started off just like any other workday for Hackensack Meridian JFK University Medical Center Emergency Medical Technician (EMT) Michael (Mike) DiMeglio, 28. Although Mike had been diagnosed with COVID-19 13 days before, he was fully recovered and ready to start his noon-to-midnight shift.
But when Mike was doing a pre-shift rig check on his emergency medical services (EMS) vehicle at his station, he noticed something odd.

Tufts University Researchers Discover New Function Performed by Nearly Half of Brain Cells

Researchers at Tufts University School of Medicine have discovered a previously unknown function performed by a type of cell that comprises nearly half of all cells in the brain.

The scientists say this discovery in mice of a new function by cells known as astrocytes opens a whole new direction for neuroscience research that might one day lead to treatments for many disorders ranging from epilepsy to Alzheimer’s to traumatic brain injury.

For Neurons, Where They Begin Isn’t Necessarily Where They End

Scientists at UC San Diego School of Medicine and Rady Children’s Institute of Genomic Medicine describe novel methods for inferring the movement of human brain cells during fetal development by studying healthy adult individuals who have recently passed away from natural causes.

Mount Sinai Launches the Brain and Body Research Center, Among the First in the U.S.to Focus Solely on How the Brain and Body Interact

Have you ever experienced a stressful time in your life and then caught a cold, or wondered why you feel sad and depressed when you’re sick? It turns out that it’s not all in your head.

Recent research spanning the fields of neuroscience and immunology suggests that when the brain senses a threat in the environment—whether it be physical, psychological, or social—it sends signals via a complex network of peripheral nerves that mobilize the immune system, readying it to protect us from injury.

Preparing for exascale: Argonne’s Aurora supercomputer to drive brain map construction

Argonne researchers are mapping the complex tangle of the brain’s connections — a connectome — by developing applications that will find their stride in the advent of exascale computing.

Mount Sinai Neurobiologist Selected as a Howard Hughes Medical Institute Investigator

The Howard Hughes Medical Institute (HHMI) has selected Ian Maze, PhD, Associate Professor of Neuroscience, and Pharmacological Sciences, at the Icahn School of Medicine at Mount Sinai, as an HHMI Investigator.

New research “sniffs out” how associative memories are formed

Has the scent of freshly baked chocolate chip cookies ever taken you back to afternoons at your grandmother’s house? Has an old song ever brought back memories of a first date? The ability to remember relationships between unrelated items (an odor and a location, a song and an event) is known as associative memory.

146th Annual Meeting of the ANA to Focus on Research and Development of Neurologic Disease Therapeutics

ANA’s Virtual Annual Meeting will offer scientific symposia highlighting cutting-edge research in neurology, Interactive Workshops that spotlight advances across the full spectrum of neurologic and neuroscience subspecialties, and Professional Development courses to help academic neurologists and neuroscientists at all career levels connect and excel.

Contrary to expectations, study finds primate neurons have fewer synapses than mice in visual cortex

A UChicago and Argonne National Laboratory study analyzing over 15,000 individual synapses in macaques and mice found that primate neurons have two to five times fewer synapses in the visual cortex compared to mice – and the difference may be due to the metabolic cost of maintaining synapses.

Neuroactive Steroids May Induce Prolonged Antidepressant Effects by Altering Brain States

A new study by researchers from Tufts University School of Medicine and Sage Therapeutics discovered that neurosteroids (allopregnanolone analogs) may alter network states in brain regions involved in emotional processing, which may explain the prolonged antidepressant effects of these compounds.
