Previous imaging research has identified an area on the human posterior superior temporal sulcus (STS) activated upon viewing biological motion. The current experiments explore the relationship between neural activity within this region and perceptual experience. Biological motion perception is orientation dependent: inverting point-light animations make them more difficult to see. We measured activity levels within this region as observers viewed inverted point-light animations. We also… 
Repetitive TMS over posterior STS disrupts perception of biological motion
TLDR
This work has used repetitive transcranial magnetic stimulation to temporarily disrupt cortical activity within the pSTS and subsequently measured sensitivity to biological motion, demonstrating that normal functioning of the posterior STS is required for intact perception of biological motion.
Learning to See Biological Motion: Brain Activity Parallels Behavior
TLDR
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 Areas Active during Visual Perception of Biological Motion
TLDR
It is reported that the occipital and fusiform face areas (OFA and FFA) also contain neural signals capable of differentiating biological from nonbiological motion.
Perceived causality influences brain activity evoked by biological motion
TLDR
A strong hemispheric bias in the role of the pSTS in the perception of causality of biological motion is demonstrated in an observer who watched the hand and arm motions of an individual when that individual was, or was not, the cause of the motion.
Brain Activity Evoked by the Perception of Human Walking: Controlling for Meaningful Coherent Motion
TLDR
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).
Right STS responses to biological motion in infancy – An fNIRS study using point-light walkers
TLDR
The results suggest that biological motion is processed differently in the right middle posterior temporal cortex in infancy, and that articulated motion is a critical feature in biological motion processing at this early age.
The human temporal lobe integrates facial form and motion: evidence from fMRI and ERP studies
TLDR
Data suggest that regions of temporal cortex actively integrate form and motion information-a process largely independent of low-level visual processes such as changes in local luminance and contrast.
Reading about the actions of others: Biological motion imagery and action congruency influence brain activity
TLDR
The hypothesis that reading can engage higher visual cortex in a content-specific manner is supported, and the presence of biological motion should be controlled as a potential confound in fMRI studies using story comprehension tasks.
A motion aftereffect from visual imagery of motion
TLDR
It is found that following prolonged imagery of motion in one direction, people are more likely to perceive real motion test probes as moving in the direction opposite to the direction of motion imagery.

Brain Areas Involved in Perception of Biological Motion
TLDR
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
TLDR
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
TLDR
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.
A direct demonstration of functional specialization within motion-related visual and auditory cortex of the human brain
TLDR
The technique of functional magnetic resonance imaging was used, in order to image the same subjects repeatedly, and it was found that each of the three motion stimuli activated specific parts of the V5 complex.
Activation in Human MT/MST by Static Images with Implied Motion
TLDR
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
TLDR
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.
TLDR
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
TLDR
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.

TLDR
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.
TLDR
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.
