Functional properties of individual neuronal branches isolated in situ by laser photoinactivation.
The functional properties of an isolated dendritic branch of an identified sensory interneuron in the cricket were studied. The branch responded to wind stimuli directed at the animal and displayed a distinct directional sensitivity to those stimuli. A technique was used that allows a neuron to be specifically lesioned in a semi-intact preparation during intracellular recording. Lesioning was achieved by dye-sensitized photoinactivation with a laser epi-illumination stereomicroscope.
