Neurons, networks, and behavior


How does light energy falling on the back of our eye get interpreted as a particular image of our friend or a painting or a leaf? How does a cockroach escape imminent predation by a toad? How does a slug remember that a recent poke wasn’t dangerous? How do we remember? A rigorous consideration of general principles of neural integration at the cellular, sensory, central, and motor levels of organization will serve as the groundwork for an examination of such questions of integration. Then we will apply those principles to particular systems including: locust flight, cockroach escape,the role of giant fibers in crayfish behavior, memory and learning in invertebrates and vertebrates, and vertebrate visual systems (from light transduction in the retina through integration in the visual cortex). Students will read appropriate primary literature (both classical and contemporary) and conduct their own research projects.

This may be review for some of you but we will begin with this:

Diffusion potential (Eion )
Basis of resting membrane potential (Em(rest)  )
Active and passive membrane responses
Ionic basis of action potential
Synaptic function (difference between currents and potentials)-neuromuscular junction (synapse) as example
