Distinct systems for automatic and cognitively controlled time measurement:
evidence from neuroimaging.
Current opinion in neurobiology, 13 (2):
250--255 (April 2003)Abstract
A recent review of neuroimaging data on time measurement argued that
the brain activity seen in association with timing is not influenced
by specific characteristics of the task performed. In contrast, we
argue that careful analysis of this literature provides evidence
for separate neural timing systems associated with opposing task
characteristics. The 'automatic' system draws mainly upon motor circuits
and the 'cognitively controlled' system depends upon prefrontal and
parietal regions.
