As Emma arrived at the meeting room, she saw Ryan already seated, with a stack of papers and a projector screen behind him. He began to explain their recent findings on the electrical properties of neurons.

Ryan smiled. "Well, it all starts with the cell membrane. It's semi-permeable, allowing certain ions to pass through while keeping others out. This selective permeability creates an electrical gradient across the membrane, known as the resting membrane potential."

Ryan grinned. "Ah, the action potential is the key to neuronal communication. It's a rapid change in the membrane potential that travels down the length of the axon, allowing the neuron to transmit information to other cells."

Emma shook her head, intrigued. "Tell me more."

Emma's mind was racing. She had always been fascinated by the complex mechanisms of neurons. "And what about the action potential?" she asked.
