NEW YORK (Reuters Health) - A sudden loss of hearing can be an early warning of impending stroke, according to results of a study released Thursday.

Dr. Herng-Ching Lin and colleagues at Taipei Medical University identified 1423 adult patients hospitalized in 1998 with a first episode of sudden hearing loss and matched each "case" patient to four "control" patients.

Patients in the hearing loss group were significantly more likely to have hypertension (high blood pressure), diabetes, and elevated cholesterol levels, the investigators note

Visual- and saccade-related signals in the primate inferior colliculus

The inferior colliculus (IC) is normally thought of as a predominantly auditory structure because of its early position in the ascending auditory pathway just before the auditory thalamus. Here, we show that a majority of IC neurons (64% of 180 neurons) in awake monkeys carry visual- and/or saccade-related signals in addition to their auditory responses (P < 0.05). The response patterns involve primarily excitatory visual responses, but also increased activity time-locked to the saccade, slow rises in activity time-locked to the onset of the visual stimulus, and inhibitory responses
