PSYB51H3 Lecture Notes - Lecture 12: Olfactory Receptor Neuron, Olfactory Bulb, Phenethyl Alcohol
Document Summary
Lecture 12 - olfaction and taste; spatial orientation and multisensory perception. Ikea manipulate you to buying furniture using smell. Attention do(cid:374)(cid:859)t (cid:374)eed to pa(cid:455) atte(cid:374)tio(cid:374) to it; seeps i(cid:374)to our (cid:272)o(cid:374)s(cid:272)ious(cid:374)ess. Olfaction does not need to go through the thalamus; it goes directly to the brain. Odors: olfactory sensations anything you can smell. Chemical compounds that are : volatile, small, hydrophobic. But not all- methane fits the criteria and also co but no smell. Olfactory cleft: secondary purpose of the nose is for smelling. The olfactory epithelium: the (cid:862)reti(cid:374)a(cid:863) of the (cid:374)ose (cid:272)o(cid:374)tai(cid:374)s (cid:1007) t(cid:455)pes of (cid:272)ells: supporting cells for structure (cid:1006). Lesions to olfactory nerve cause anosmia reduction in sense of smell: head trauma (damage to the cribriform plate) holes where cranial nerve travels through. Infections, loss of flavor/taste as well as danger warning (cid:272)o(cid:373)(cid:373)o(cid:374) i(cid:374) parki(cid:374)so(cid:374)(cid:859)s a(cid:374)d alzhei(cid:373)er(cid:859)s - quite common: similar function as a razor metal plate with lots of holes.
