Zinc: a surprise target in regenerating the optic nerve after injury
Researchers at Boston Children's Hospital show that chelating zinc that is released as a result of an injured optic nerve gets cells to live longer, perhaps indefinitely, with dramatic levels of axon regeneration in a mouse model.

When silencing phantom noises is a matter of science
With a clever approach, researchers point to the first gene that could be protective of tinnitus. The study published in Frontiers in Behavioral Neuroscience reports that without normal function of the GLAST gene, animals are more prone to develop tinnitus.

Prevalence, severity of tinnitus in the US
Approximately 1 in 10 adults in the United States have tinnitus, and duration of occupational and leisure time noise exposures are correlated with rates of tinnitus and are likely targetable risk factors, according to a study published online by JAMA Otolaryngology-Head & Neck Surgery.

Emotion processing in the brain changes with tinnitus severity
A new fMRI study published in the journal PLOS ONE finds that patients with lower tinnitus distress use an altered pathway to process emotional information -- the brain's frontal lobe, as oppossed to the amygdala.The researchers suggested that the greater activation of the frontal lobe might be helping to control emotional responses and reduce tinnitus distress.

Funduscopy exams now done infrequently
A Loyola University Medical Center study published in the journal Frontiers in Neurology has found that direct funduscopy exams are being performed infrequently. Researchers who examined patient records found that it was used during the initial evaluation on only 26% of patients with primary visual symptoms, 25% of patients with headaches, and 5% of patients with altered mental status.

Scientists test new gene therapy for vision loss from a mitochondrial disease
Researchers have developed a novel mouse model for the vision disorder Leber hereditary optic neuropathy, and found that they can use gene therapy to improve visual function in the mice.

Ringing in the ears and chronic pain enter by the same gate
Advances in brain imaging and associated techniques have enabled researchers to begin homing in on the structural and functional bases of tinnitus and chronic pain, revealing what appears to be a central gatekeeping system implicated in both. Researchers ingrate the latest findings into a disease model of both disorders in the journal Trends in Cognitive Sciences.
