5B40.10 • Neuron Model

Location: Cabinet 2

Photo Shows Apparatus used by the University of Texas at Austin.

Instructions / Notes:

• This is a model of a neuron and an axon with specific parts labeled.
• Labelled key included with demo.

Concepts Conveyed:

• A non-signaling neuron maintains a stable voltage across its membrane called the resting potential. This resting potential is determined by the concentration gradient of ions across the membrane, with the most abundant being Na+/K+ and Cl-.
• The electrical potential difference between the inside and outside of the cell is called the membrane potential, with the inside being more negative than the outside.
• Neurons generate electrical signals through controlled changes in the permeability of their cell membrane to particular ions.
