Neural Signals: Properties and Mechanisms

This lecture covers the neural signals recorded from the brain and peripheral nerve, discussing the mechanical properties of nerves, the building blocks of neurons, and the origin of resting potential. It also delves into the viscoelastic nature of neural tissues, the spinal cord's shape and dimensions, and the mechanical properties of explanted spinal cords. The instructor explores the passive electrical properties of neurons, the membrane potential, and the Nernst potential. Additionally, the lecture touches on the brain's viscoelasticity, the dura mater's stiffness, and the brain's pulsation with blood flow and respiratory rhythm.
