combs and heated rollers.
According to its major aspects and briefly described, the present invention is a system of components that cooperate with each other to shield the exposed skin of the ears, forehead and neck against contact by heated hair care device during use. The three components include a head band, two ear pieces and a neck shield. The head band and neck shield attach to the ear pieces which cover the ears, each cupping the pinna of the ear. The three components will not prevent burns in every case but can prevent or limit injury from the proximity of the hot curling iron and the occasional, inadvertent touching of the iron to the skin.
A feature of the present invention is the ear piece. This component covers theEST, vanillin, and acetone. Smelling of EST activated the anterior hypothalamus in controls, but not anosmics. Neither did the anosmics display cerebral activations with AND or vanillin. Clusters were detected only with the trigeminal odorant acetone, and only in the thalamus, brainstem, the anterior cingulate, and parts of the sensorimotor cortex. Direct comparisons with controls (controls-anosmics) showed clusters in the olfactory cortex (amygdala and piriform cortex) with AND, vanillin, and acetone, and in the anterior hypothalamus with EST. The observed absence of olfactory and presence of trigeminal activations in anosmics indicates that polyposis primarily affected signal processing via the olfactory mucosa. The anosmics inability to activate the hypothalamus with EST, therefore, suggests that in healthy men EST signals were primarily transmitted via the olfactory system.
