Good question: how doesour brain experience time?  Inresearching your question, I came across an article which opens with anargument that if we were to mess with our perception of time, we could, in away, live longer.  If we make it so thatevery minute that passes feels likean hour has gone by, we could expand the human lifespan.  Our ability to detect the passing of time andestimate intervals of time seems to be the result of a group effort.  Multiple brain structures (such as the cerebellumand basal ganglia) have been implicated as parts of the brain necessary for ourperception of time (Sinicki, n.d.).  Itis also interesting to consider how the perception of time could differ betweenindividuals.

 It is a common perception tofeel like as we get older, time starts moving quicker.  Additionally, our ability to predict timeintervals seems to become less accurate as we age (Hammond, 2012).  That is, my current prediction of how long ittakes for a minute to pass will only become less accurate from here on out. Ifso, how about individuals with MDD?  Wouldtheir perception of time be slower than normal?  Try the following link if you are curious totest the accuracy of your own perception of time:
