Week 7 - Oct. 14th
If you've forgotten how a neuron works, how an action potential
travels, or how neurotransmitters are released, you should review that
chapter in an introductory biology text.
One area of ethology is "neuroethology". This field focuses
on how behavior is generated by an animal's nervous system. Neuroethology
differs from neurobiology slightly because it approaches the questions
from an evolutionary angle as well as the mechanistic questions. This
isn't to say that neurobiolgoists don't consider evolution but it is
not always central to their research. Furthermore, a neuroethologist
(like an ethologist) is concerned with the animal in its natural environment.
We will look at a few different examples of natural adaptive behaviors
from diverse organisms to understand how their nervous systems have evolved.

Week 7 - Oct 16th
Guest Seminar Nate Sawtell
Nate will give a "hard core" neuroscience lecture. Be
prepared to stop him and ask questions. He will be presenting current
research regarding neural function using as a model organism one of the
electric fish that you will be working with in lab this week.
