Biophysics: electricity and membrane excitability (section in course 274253; Spring Semester)

The physics and chemistry of ions in solution, diffusion, osmosis, Nernst-Planck electro-diffusion equation and the Nernst potential, and the Goldman-Hodgkin-Katz equation. The Hodgkin-Huxley model of excitability, the dynamics of macroscopic and microscopic membrane ionic conductances, and methods for their measurements and analyses. Classes of mathematical models that capture the phenomenon of action potential generation at various timescales, emphasising models derived from theory of nonlinear oscillators.

Psychology & Physiology: a relational view (graduate course 278493; Winter Semester)

Analysis of fundamental constraints inherent to modern brain research aimed to understand human behavior in health and disease. Key issues in brain research (evolution, anatomy, development, adaptation and learning) will be examined using concepts from functionalist, pragmatist and relational psychoanalytic schools.
