(Due December 2nd in lecture)
As youve seen in this and other classes, biologists periodically write review papers that
summarize the current state of knowledge and thinking on a particular topic within their field.
Informal Group Neurotransmitter Presentations
Neurophys Fall 2014
Work in a group of 3(ish) to answer the following questions about your assigned
neurotransmitter, then you will share what you learn with the class. You should use the board to

The purpose of this experiment was to explore the effect of temperature on
the conduction velocity and width of the compound action potential. In order to do
this, the sciatic nerve of a Xen
Discussion Questions on Long Term Synaptic Plasticity
(from Ch 16 and Ho et al. 2011)
What is LTP?
What is LTD?
What role are they thought to play in learning and memory?
What are the presynaptic mechanisms of long term plasticity?
What are the post synap

Neurophys Fall 14
Exploring Neurophysiology with Cockroach Legs!
In this lab we will examine how some very simple electrophysiological recording and stimulation
experiments can be done using the nerves in the legs of American cockroaches (Periplane
Worksheet: Currents that cause action potentials
Draw for yourselves a graph of Vm over time for an action potential:
Note on your graph which ion flowing is responsible for each major shift in Vm (i.e., the
depolarization is because of _N
