Abstract
Last two decades witnessed a tremendous progress in our understanding of mechanisms of time perception. Time processing in the milliseconds range is automatic and subserved by primary sensory areas and a brain network comprised of supplementary motor area, primary sensorimotor cirtex and cerebellum.
Time prception in the seconds range is cognitive in nature and is dependent on the capacity of attention and working memory. It is subserved by a network comprised of supplementary motor area, dorsolateral prefrontal cortex and posterior parietal cortex.
Our subjective perception of the time flow is not only dependent on various physiological factors such as age, attention ot the intensity and valence of emotions but also on pathologic conditions such as Parkinson's disease, schizophrenia, attention defficit hyperactivity disorder or focal brain lesions (eg. cerebellum, prefrontal cortex or basal ganglia).
