Neural basis of the magnetic compass: interactions of visual, magnetic and vestibular inputs in the pigeon's brain

摘要: Single unit electrical activity was recorded extracellularly in the lateral and superior vestibular nuclei, vestibulo-cerebellum nucleus of basal optic root (nBOR) under earth-strength magnetic stimulation. Units system responded with either inhibition or excitation to stimuli only if animal moved out horizontal plane. No responses artificial field were observed when enucleation performed contralateral recording site applied total darkness. Most units nBOR slow direction changes a gradual augmentation activity. The generally weak but nevertheless statistically significant seemed be selective, i.e. different cells distinct change field. results indicate, that information provided by cues earth's strength range may conveyed from visual via projection then related active movements animal.
