Multisensory integration in the perception of moving or vibrating objects
All fishes have a wealth of senses involved in the detection of vibrating objects. These include hearing and related senses, and the less-commonly known lateral line system. Each of these senses is responsive to different aspects of the physical disturbances caused by vibratory motion. Do these multiple senses each contribute to different behaviors, or only in certain contexts? Or does each modality make a partial contribution to a single percept of an object with multiple properties? We use anatomical, physiological, and behavioral techniques in combination with surgical or pharmacological manipulation of the sensory periphery, to determine which senses are absolutely necessary for detection and what each individual sense contributes to perception. We are currently focused on the interactions between audition, motion detection, and the lateral line in the perception of the spatial location of vibrating objects.
