Long thought of as a generic alarm system, the locus coeruleus may actually be a sophisticated regulator of learning and behavior, according to a new review by MIT researchers. They will test this hypothesis with a new grant.
UC San Diego researchers and their colleagues at the Icahn School of Medicine at Mount Sinai in New York have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's "feel good" chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.
Houston Methodist Neurological Institute researchers from the department of neurosurgery shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy in his own home. The 53-year-old patient died from an unrelated injury about a month into the treatment, but during that short time, 31% of the tumor mass disappeared. The autopsy of his brain confirmed the rapid response to the treatment.
Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age.
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?
Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not. In a study published in Neurology, Mayo Clinic researchers and colleagues assessed if inflammation leads to permanent scarring in these three diseases.
Interactions of two voltage-gated calcium channels and a pump enable separate control of exocytosis and endocytosis at chemical synapses
Northwestern University engineers have developed the first full, three-dimensional (3D), dynamic simulation of a rat's complete whisker system, offering rare, realistic insight into how rats obtain tactile information.
A scientific review has found evidence that a disruption in blood clotting and the first line immune system could be contributing factors in the development of psychosis.
A previously unknown kind of human brain cell appears to help people center themselves in their personal maps of the world, according to a new study from neuroscientists at Columbia Engineering. This discovery shed light on the cellular mechanisms underlying navigation and memory in humans, as well as what parts of the brain might get disrupted during the kinds of memory impairments common in neurodegenerative diseases such as Alzheimer's.
