What does the thalamus do? - 1. relay station (receives info and tells it where to go) 2. receives sensory fibers from optic tract, ears, and spinal cord 3. receives motor info from cerebellum 4. projects fibers to the cerebrum 5. receives messages from all the sensory receptors and relays it to...

How does the Morris Water Maze task function? - A mouse is placed in a murky water tank and, because mice do not enjoy being in water, it will try to look for a way out, and after many trials the mouse learns that there is a platform somewhere in the tank upon which it can rest from swimming, and ...

Steps for an Action Potential - Depolarizing stimulus, if threshold is met - Na+ and K+ channels begin to open, Na+ enters the cell and depolarizes it, Na+ channels close and K+ channels open fully, K+ exits the cell until it is hyperpolarized, K+ channels close, cell returns to resting membrane p...

A postsynaptic potential is excitatory (EPSP) if the ion involved has a reversal potential (Eion) that is more depolarized than the resting membrane potential (Vm or Vrest), even if that Eion is hyperpolarized to the threshold for firing an action potential. - False why?>> For a postsynapt...

emphysema and fick's equation - airway obstruction as a result of inorganic particles --> triggers the production of elastase which breaks down elastin --> alveoli lose elastance --> alveoli recoil --> increase in T and decrease in A --> lower gas exchange inspired partial pressur...
