Research overview: central integration of whisker and visual signals

Tactile information from the whiskers is integrated with other senses in brain regions that coordinate orienting and targeting, including midbrain structures involved in directing attention and movement. This overview surveys how whisker input is combined with visual and auditory signals to guide the cat toward objects and prey. Such multisensory integration allows the cat to form a unified spatial estimate, drawing on whichever senses are most informative at a given moment. The survey relates this to the cat's role as a model in sensorimotor neuroscience and to the way close-range whisker cues can take precedence when vision is limited. It frames the whisker sense as part of a coordinated system rather than an isolated channel. Understanding central integration shows how the brain blends touch with sight and sound, enabling smooth transitions, for example from visually stalking prey at a distance to tactilely guiding the final bite.
