title: Central projection of auditory receptors in the prothoracic ganglion of the buschcricket Psorodonotus illyricus (tettigoniidae): computer-aided analysis of the end branch pattern.
abstract: The projection patterns of morphologically and functionally identified auditory and auditory-vibratory receptor cells of receptor organs (the crista acustica and the intermediate organ) in the foreleg of the tettigoniid Psorodonotus illyricus, were investigated with combined recording and staining techniques, and subsequent histological examination and morphometric measurements. With the application of a computer program (AutoCAD), three-dimensional reconstructions of the axon end branches of receptor cells within the neuropile of the anterior Ring Tract (aRT) were made, in order to determine, the entire shape of each, the pattern and density of the end branches, and the positions of the target areas within the auditory neuropile. Clear differences for different functional types of receptors were found.
