PSYB51H3 Lecture Notes - Lecture 12: Timpani, Orbitofrontal Cortex, Angular Velocity
Document Summary
Chemical compounds that are: volatile, small, hydrophobic. Nose: small ridges and sniffing allow for air flowing into the olfactory apparatus which is in the roof of the nose of the olfactory cleft which contains the olfactory. Olfactory receptors (ors) interact with odorants. Lesions to the olfactory nerve can cause anosmia. Anosmia reduction in sense of smell: caused by head trauma (damage to the cribriform plate) which the nerve goes through, loss of flavor/taste is a danger warning, earl(cid:455) s(cid:455)(cid:373)pto(cid:373) for alzhei(cid:373)er"s a(cid:374)d parki(cid:374)so(cid:374)"s.
