Serving about 180 students per year, the Neurolab plays host to two courses: BiBB251 (Cellular Neurobiology) and BiBB492 (Experimental Methods in Synaptic Physiology). In BiBB251, about 140 students run computer simulations before spending several weeks recording from some very interesting neurons in the buccal ganglia of the freshwater snail Helisoma trivolvis. In BiBB492, a smaller group of advanced students spends a few weeks on each of three important and interesting experimental preparations: besides Helisoma, we use the abdominal ganglion of Aplysia californica (well-known for its role in studies of learning and memory) and the tail prep from the crayfish (Procambarus clarkii), a convenient and easy way to observe synaptic activity at the neuromuscular junction.  The Neurolab is also host to our new Summer Program in Computational Neuroscience.
