Avian Cerebellum Specialization In Relation To Acrobatic Courtship Displays In Manakins (Pipridae), Steven Ray Wilkening
Electronic Theses and Dissertations
The courtship displays of male manakins (Pipridae) involve an array of acrobatic and postural elements. Previously it was found that species with elaborate displays exhibit specializations in motor planning and coordination areas of the brain. Several studies have suggested a relationship between cerebellum (Cb) morphology and distinct motor-related functions for the anterior Cb (somatosensory, flying, hopping/walking), posterior Cb (vision, audition, flying, hopping/walking), and vestibular Cb (flying, hopping/walking, vestibular). The anterior, posterior and vestibular Cb as well as basic morphological features of the Cb were measured and tested for a relationship with courtship display complexity in manakins. I compared Cb morphology …
