BIOL 4041 Lecture Notes - Lecture 10: Antennal Lobe, Sensillum, Olfactory Bulb
Document Summary
Or83b is found in every sensory neuron in the y; February 10, 2016: synthesize promoter region and gal4 and put into embryo, put in reaper instead of olfactory receptor and it will kill the cell, you can express a different gene, you can silence a gene. Ab3a expresses 2 protein and both are gone in the mutant, insert the gal4, cross with. The fundamental problem: have a bunch of recordings from sensillae but do not know what proteins the ngerprints are produced from: looking for which sensillae contains the known gene by looking at partner sensillae. Sensillum types are not randomly distributed across antennae. Projections neuron signals do not have a 1-to-1 relationship with incoming neurons: experiment looking at ca2+ imaging to demonstrate. Interneurons become excited and reach across glomerulus and inhibit others which changes pattern to projection neurons: antennal lobe contains glomeruli. These are knots of tons of dendrites and axon terminals.
