Repetitive TMS over posterior STS disrupts perception of biological motion

Learning to See Biological Motion: Brain Activity Parallels Behavior

Individuals improve with practice on a variety of perceptual tasks, presumably reflecting plasticity in underlying neural mechanisms, and changes in activation within the posterior superior temporal sulcus and the fusiform face area, brain areas involved in perception of biological events are examined.

Specificity of regions processing biological motion

Using functional magnetic resonance imaging and point light displays portraying six different human actions, we were able to show that several visual cortical regions, including human MT/V5 complex,

Brain Activity Evoked by the Perception of Human Walking: Controlling for Meaningful Coherent Motion

It is determined that the superior temporal sulcus (STS) responds more strongly to biological motion (as conveyed by the walking robot) than to a nonmeaningful but complex nonbiological motion (a disjointed mechanical figure) and a complex and meaningful nonbiology motion (the movements of a grandfather clock).

Brain Areas Involved in Perception of Biological Motion

Consistent with earlier neuroimaging and single-unit studies, this pattern of results points to the existence of neural mechanisms specialized for analysis of the kinematics defining biological motion.

Motion-responsive regions of the human brain

Functional magnetic resonance imaging was used to map motion responsive regions of the human brain by contrasting passive viewing of moving and stationary randomly textured patterns, and flicker-induced-activation introduced a dichotomy amongst these motionresponsive regions.

Specific Involvement of Human Parietal Systems and the Amygdala in the Perception of Biological Motion

The results demonstrated that the perception of scripts of goal-directed hand action implicates the cortex in the intraparietal sulcus and the caudal part of the superior temporal sulcus, both in the left hemisphere.

Activation in Human MT/MST by Static Images with Implied Motion

fMRI activation within MT/MST is found during viewing of static photographs with implied motion compared to viewing of photographs without implied motion, suggesting that brain regions involved in the visual analysis of motion are also engaged in processing implied dynamic information from static images.

The constructive nature of vision: direct evidence from functional magnetic resonance imaging studies of apparent motion and motion imagery

The comparison between the results obtained with objective motion, apparent motion and imagined motion provides further insights into a complex cortical network of motion‐sensitive areas driven by bottom‐up and top‐down neural processes.

Human cortical regions activated by wide-field visual motion: an H2(15)O PET study.

P positron emission tomography was used to localize human cortical regions responding to wide-field visual motion and showed that the activity caused by the two types of movement was comparable in these early visual cortical regions.

Temporal Cortex Activation in Humans Viewing Eye and Mouth Movements

Results suggest that a superior temporal region centered in the STS is preferentially involved in the perception of gaze direction and mouth movements, and may be functionally related to nearby superior temporal regions thought to be involved in lip-reading and in the Perception of hand and body movement.

Object-related activity revealed by functional magnetic resonance imaging in human occipital cortex.

Evidence for an intermediate link in the chain of processing stages leading to object recognition in human visual cortex is reported, which suggests that the enhanced responses to objects were not a manifestation of low-level visual processing.

Intact “biological motion” and “structure from motion” perception in a patient with impaired motion mechanisms: A case study

The patient with bilateral lesions involving the posterior visual pathways, affecting the lateral parietal-temporal-occipital cortex and the underlying white matter was able to identify actions from the evolving pattern of dots placed at the joints of a human actor as well as discriminating three-dimensional structure of a cylinder from motion in a dynamic random-dot field.
