I haven't actually opened or extracted the content of your PDF yet (no tool calls have completed in this conversation), so I don't have its text available to pull neurophysiology questions from.

Could you re-share the PDF or let me process it in a follow-up so I can extract the actual questions? Once I have the extracted text, I can filter and list only the ones related to neurophysiology (nerve conduction, action potentials, synaptic transmission, reflexes, muscle physiology, CNS/PNS function, etc.).
