adrenaline (epinephrine). A hormone of the adrenal medulla which, instilled in the eye, causes a constriction of the conjunctival vessels, dilates the pupil and diminishes the intraocular pressure. See adrenergic receptors; ocular decongestant; naphazoline; neurotransmitter; noradrenaline (norepinephrine).
For tinnitus with hearing impairment, press and massage the hollows behind both earlobes and the jawbone directly beneath the ears; and/or press on the gums behind the wisdom teeth with a pencil eraser, or bite down on a wad of cotton in the same location for several minutes. Do this once per day.
19 January 2011âScientists say they can cure tinnitusâpersistent ringing in the earsâby pairing certain tones with stimulation of a nerve in the neck. Tinnitus is caused by noise damage to the sensory cells in the inner ear, or cochlea. This damage results in changes to the organization of the brainâs auditory cortex, a region that contains a frequency map of sounds. Damage to the inner ear causes a portion of this map to take over other parts of the cortex, causing the ringing.
