Now Neurons Work
(8 steps to nerve-vana)

by Greg Crowther


Context

Information passes through the nervous system as electrical signals within neurons and as chemical signals between neurons. This song summarizes the entire information transfer process in eight short phrases, which serve as a mnemonic from which students can fill in the details.


Lyrics

Calcium enters the axon.
Transmitter gets dumped.
Ligands open channels.
PSPs get summed.
The hillock reaches threshold.
Membrane voltage spikes.
Spikes move down the axon ...
Toward calcium's next strike!

And that’s eight steps.
They’re electric ... and chemical.
Eight steps ... of info flow.
Eight steps.
They’re electric ... and chemical.
Eight steps ... of info flow.
Eight steps!
