Megjegyzések:	The prey-catching behavior of the frog is a complex, well-timed sequence of stimulus response chain ofmovements. After visual analysis of the prey, a size dependent program is selected in the motor patterngenerator of the brainstem. Besides this predetermined feeding program, various direct and indirectsensory inputs provide flexible adjustment for the optimal contraction of the executive muscles. The aimof the present study was to investigate whether trigeminal primary afferents establish direct contactswith the jaw opening motoneurons innervated by the facial nerve.The experiments were carried out on Rana esculenta (Pelophylax esculentus), where the trigeminal andfacial nerves were labeled simultaneously with different fluorescent dyes. Using a confocal laser scanningmicroscope, close appositions were detected between trigeminal afferent fibers and somatodendriticcomponents of the facial motoneurons.Quantitative analysis revealed that the majority of close contacts were encountered on the dendritesof facial motoneurons and approximately 10% of them were located on the perikarya. We suggest thatthe identified contacts between the trigeminal afferents and facial motoneurons presented here may beone of the morphological substrate in the feedback and feedforward modulation of the rapidly changingactivity of the jaw opening muscle during the prey-catching behavior.
