abstract = {The human brain readily perceives fluent movement from
static input. Using functional magnetic resonance imaging,
we investigated brain mechanisms that mediate fluent
apparent biological motion (ABM) perception from sequences
of body postures. We presented body and nonbody stimuli
varying in objective sequence duration and fluency of
apparent movement. Three body postures were ordered to
produce a fluent (ABC) or a nonfluent (ACB) apparent
movement. This enabled us to identify brain areas involved
in the perceptual reconstruction of body movement from
identical lower-level static input. Participants judged the
duration of a rectangle containing body/nonbody sequences,
as an implicit measure of movement fluency. For body
stimuli, fluent apparent motion sequences produced
subjectively longer durations than nonfluent sequences of
the same objective duration. This difference was reduced for
nonbody stimuli. This body-specific bias in duration
perception was associated with increased blood oxygen
level-dependent responses in the primary (M1) and
supplementary motor areas. Moreover, fluent ABM was
associated with increased functional connectivity between
M1/SMA and right fusiform body area. We show that perceptual
reconstruction of fluent movement from static body postures
does not merely enlist areas traditionally associated with
visual body processing, but involves cooperative recruitment
of motor areas, consistent with a “motor way of
seeing”.},
