Stimulation deforms lamellae in Pacinian corpuscles, stretching the neuron membrane, opening sodium channels, and causing sodium influx to generate a potential.
When stimulated, lamellae in Pacinian corpuscles deform, stretching the sensory neuron membrane and opening stretch-mediated sodium channels. This allows sodium ions to diffuse in, creating a generator potential.
| Front | Pacianian corpuscle when stimulated |
|---|---|
| Back | Lamellae are deformed and press on the sensory nerve ending which causes the sensory neurone cell membrane to stretch which deforms the stretch-mediated sodium ion channels. The channels open and sodium ions diffuse into cell and generator potential produced |
