Recruitment of periventricular parietal regions in processing cluttered point-light biological motion.
Recent findings point to the existence of a cortical-subcortical parietal network that drives attention-related integration of features and elements. Here we ask whether the functioning of this network might be modulated by early periventricular lesions. To this end, a cohort of adolescents who were born premature with different severity of bilateral periventricular leukomalacia (PVL) and two g...
متن کاملForm overshadows ‘opponent motion’ information in processing of biological motion from point light walker stimuli
The point light walker (PLW) has been taken to demonstrate the existence of mechanisms specialised in the processing of biological motion, but the roles of form and motion information in such processing remain unclear. While processing is robust to distortion and exclusion of the local motion signals of the individual elements of the PLW, the motion relationships between the elements - referred...
متن کاملBistable Alternation of Point-Light Biological Motion
The facing-in-depth of point-light biological motion is ambiguous: the frontal and back view look the same. However, since earlier studies found a very strong perceptual bias in point-light biological motion, it is unknown whether it evokes an alternating (bistable) percept. In the present study, naive, untrained observers viewed point-light stimuli in half-profile view. All participants experi...
متن کاملPerception of biological motion in parietal patients.
Three unilateral parietal patients were tested on their perception of biological motion, a special case of form-from-motion. Two patients had the lesion in the right, and one in the left parietal area. All patients could easily perform a classical form-from-motion task [Neuron 32 (2001) 985], but they were severely impaired in a visual search task using biological motion sequences. In particula...
متن کاملProcessing of biological motion point-light displays by baboons (Papio papio).
Humans apply complex conceptual judgments to point-light displays (PLDs) representing biological motion (BM), but how animals process this kind of display remains uncertain. Four baboons (Papio papio) were trained to discriminate BM from nonbiological motion PLDs using an operant computerized test system. Transfer tests were given after training with novel BM stimuli representing humans or babo...
