• To elucidate the mechanisms of mechano-electrical transduction within the Pacinian corpuscle.

Main Methods:

• Integration of experimental data and prior theoretical research.
• Development of a model incorporating the Pacinian corpuscle's capsule and transduction elements.
• Simulation of receptor potential and nerve terminal spike generation.

Main Results:

• The model successfully replicates key experimental findings for various stimuli.
• Accurate prediction of receptor potential dynamics, frequency response, and spike generation.
• Validation against receptor potential time course, frequency response, threshold curves, and firing patterns.

Conclusions:

• The developed mathematical model provides a robust explanation for Pacinian corpuscle transduction.
• The model offers insights into the fundamental aspects of mechanosensory processing.
• Predictions suggest avenues for future experimental investigations into Pacinian corpuscle function.
