ICA images and spike discharge patterns of a mechanosensitive neuron in response to nicotine and to deformation of several neurites. The CCD camera picture of a neuron is shown in (A). The ICA image of the nicotine response is shown in (B). (C–F) Show the ICA images of the responses to mechanical deformation of different neurites of the same neuron. The sites of deformations are marked by black arrows. Very few neurites activated by nicotine application (B) are not detectable after deformation of different neurites (C–F). It is evident that mechanosensitive neurites are also invaded by soma spikes generated by deformation of other neurites. The firing behavior of the neuron was slowly adapting independent of which neurite was deformed.
