Week 6 - Oct. 9th
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.
