BIOS 286 Lecture Notes - Lecture 10: Netrin, Aroma Compound, Random Variable
Document Summary
Possibly caused by reduction of asymmetry in the brain. The nervous system of the nematode caenorhabditis elegans. Reproducible functions, morphologies and synaptic connections, 5000 chemical synapses, 600 gap junctions, 200 nmjs. Green fluorescence protein (gfp) or rfp reporters. C. elegans has a short life cycle. We culture c. elegans on petri dishes in the lab. Seeded with e. coli strain (hb101, op50) as worm food source. Transfer worms between plates or from plates to agarose pads for scoring and injection: elegans led to many important discoveries that are conserved from worms, elegans led to many important discoveries that are conserved from worms to humans. Lim and pou proteins in neuronal cell fate. Awc and ase neuron pairs display molecular and functional asymmetries. The left and right awc olfactory neurons express different receptors and sense different odors. What is the advantage of awc neuronal asymmetry? increases sensory diversity. Event or system is one that is unpredictable because of a random variable.
