• Electro-Hydrolysis

  You look at the reactions and decide on your course of action. What do you decide to do and why? You decide to do electrolysis on the molten salt because it is the only possible way to do it.

• Intracellularly recording from pyramidal cells in a mouse

  In the neocortex, this translates to a higher number of action potentials occuring in the serotonin regulation loop.

• Membrane Potentials, Calcium and Muscle Contraction

  Action potentials in neurons and muscles rely on the same influx of Na+ ions to depolarize, and it is this depolarization that stimulates Ca2+ channels on the sacrolemma to open and release stored calcium.
