August 24th Please remember we have a short quiz next Thursday. Here are the answers to the quiz questions. I'll try to add some figures from Thursday's lecture over the weekend, but, so far, the technology is beyond me. Have a safe Labor Day Holiday. Here are some things from the last lecture.
All neurons have dendrites, a cell body or soma, an axon, and synapses.
This is completely true and it is something that you should learn. As an aside, the distinction between dendrite and axon is sometimes not great, and some neurons have more than one axon. 2.7 shows you a stylized drawing of a neuron and some of its internal bodyparts, i.e., organelles. Next week in class, you'll learn a bit more about chemical synapses. Then we'll review basic synaptic function and see what it looks like on the post-synaptic membrane.
