HMB200H1 Lecture Notes - Lecture 12: Olfactory Bulb, Entorhinal Cortex, Olfactory Bulb Mitral Cell
Document Summary
Hmb200h1s l12; feb. 15, 2012: olfactory = basis of limbic & memory, only olfactory bulb & process in fish nputs. So most complicated & most dimensions of. Slow but precise to define the outside process than any other sense reas. Leading to discovery of genes: axel & buck, olfactory bulb contrasts in decision-making in rats. Humans reduce contribution of main olfactory. Olfaqctory genes discovered by axel & buck: main bulb receieves input by primary rec cells cilia w recs on tips. Make genes, each 1 per neuron, then make recs. Each cell only goes to particular glomerulus/synaptic zone. Control info reaching brian via mitral cells. Ex. all that express blue rec gene only go to blue glomerulus. Labelled lined going into brain, defined by. Expressed 1 per cell, not found in brain. Large proportion of genome but not all genes used only 1/cell. So w 1 rec, only respond to 1 kind of chemical.
