Microglia play vital role in regulating neuroinflammation, research shows

A research team at Massachusetts Eye and Ear has shown that microglia, the primary immune cells of the central nervous system--including the retina of the eye--serve as "gatekeepers," or biosensors and facilitators, of neuroinflammation in a preclinical model of autoimmune uveitis.

Brain areas linked to memory and emotion aid odor navigation in humans

Species like dogs and rodents use their sense of smell to navigate toward desirable items and places and away from those they should avoid.

Researchers map auditory sensory system of the mouse brain

University of Oregon neuroscientists report that two areas of the mouse brain combine representations of what is heard and anticipated, guiding behavior that leads mice to the best reward.

Large-scale screen of mouse mutants reveals 38 new genes involved in hearing loss

A large-scale screen of mouse mutants has revealed multiple new genes involved in hearing loss, according to a study publishing April 11 in the open-access journal PLOS Biology by Karen Steel of King’s College London and the Wellcome Sanger Institute, and colleagues.

Researchers study how the auditory system achieves accurate speech recognition

For humans to achieve accurate speech recognition and communicate with one another, the auditory system must recognize distinct categories of sounds - such as words - from a continuous incoming stream of sounds.

Brain area that only processes spoken, not written words identified

Patients in a new Northwestern Medicine study were able to comprehend words that were written but not said aloud. They could write the names of things they saw but not verbalize them.

New $9.7 million NIH grant project seeks to improve hearing restoration

The University of Minnesota announced today that it will lead a $9.7 million grant over the next five years from the National Institutes for Health BRAIN Initiative to develop a new implantable device and surgical procedure with the goal of restoring more natural hearing to people who are deaf or severely hard-of-hearing.

UVA researchers discover potential contributor to age-related hearing loss

Researchers at the University of Virginia School of Medicine have discovered a new potential contributor to age-related hearing loss, a finding that could eventually help doctors identify people at risk.

Least-active neurons play more important role in brain behavior than previously assumed

Brain cells recorded as among the least electrically active during a specific task may be the most important to doing it right.

Gene therapy restores hearing in mice with congenital genetic deafness

In collaboration with the universities of Miami, Columbia and San Francisco, scientists from the Institut Pasteur, Inserm, CNRS, Collège de France, Sorbonne University and the University of Clermont Auvergne have managed to restore hearing in an adult mouse model of DFNB9 deafness - a hearing disorder that represents one of the most frequent cases of congenital genetic deafness.

Multinational initiative to study familial primary distal renal tubular acidosis

In addition to regulating the body's fluid balance, by excreting greater or smaller amounts of urine, the kidneys also maintain the proper balance of electrolytes (salts) and the pH (an acid-base equilibrium) within our body.

Study finds genetic vulnerability to use of menthol cigarettes

A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive.

Largest description of ST3GAL5 deficiency combined using data from 104 individuals

Researchers have combined the largest description of ST3GAL5 deficiency using detailed natural history data from 104 individuals of Amish ancestry born between 1986 and 2017 with a definite or probable diagnosis of ST3GAL5 deficiency.

Study highlights great diversity of language development in children with ASD

A close collaboration between University of Connecticut (Letitia Naigles (PI) and Deborah Fein) and Interacting Minds Centreresearchers (Riccardo Fusaroli and Ethan Weed) is exploring how parents and children influence each other when they interact, and the longer term impact this has on language acquisition.

Unique form of chronic sinusitis found in older patients

Older patients with a diagnosis of chronic sinusitis -- a disease of the nasal cavity and paranasal sinuses that often persists over many years -- have a unique inflammatory signature that may render them less responsive to steroid treatment, according to a new study published by Vanderbilt researchers.

Scientists discover new genetic mutations causing inherited deaf-blindness

A team of scientists from Sechenov First Moscow State Medical University together with their colleagues from leading scientific centers of Moscow and India described a number of genetic mutations causing Usher syndrome (inherited deaf-blindness).

Researchers identify hundreds of new genes linked to blindness in lab mice

Hundreds of new genes linked to blindness and other vision disorders have been identified in a screen of mouse strains. Many of these genes are likely important in human vision and the results could help identify new causes of hereditary blindness in patients.

Study lays foundation for addressing unresolved questions in human aging

Doctors have long observed that biological age and chronological age are not always one and the same. A 55-year-old may exhibit many signs of old age and have numerous age-related diseases, whereas an 80-year-old may be healthy and robust.

UI study leads to better understanding of signaling capacity between neurons

The fundamental process of information transfer from neuron to neuron occurs through a relay of electrical and chemical signaling at the synapse, the junction between neurons. Electrical signals, called action potentials, cause voltage-gated calcium channels on the presynaptic neuron to open.

CTF along with NTAP and Sage announce first-ever open data portal for neurofibromatosis

The Children's Tumor Foundation, together with the Neurofibromatosis Therapeutic Acceleration Program and Sage Bionetworks, has announced the first-ever open data portal for scientific research results in the field of neurofibromatosis.
