3. I am my Connectome

4. nodes of Ranvier

6. Electrochemical Impulses
Nervous system is a rapid communication network that detects stimuli and coordinates responses to stimuli
The functional unit of the nervous system is the neuron (nerve cell)
Neurons transmit information over distances similar to a telephone wire
Information is conducted along the neural cell membrane as an electrochemical impulse

18. What happens between neurons?
Synapses
Mouse Party task (see next slide)

19. Homework Watch Nerve Impulse Animation and make notes
