CONTEXT(Help)

The Arrow of Time »The Arrow of Time The Arrow of Time ☜A map exploring some issues concerning the nature of time that lie at the boundary of physics and philosophy. The map follows up a talk to the Blackheath Philosophy Forum on 2 April 2011 by Huw Price, Professor of Philosophy and director of the Center for Time at Sydney University.☜F1CEB7

Brain doesn't work with instants »Brain doesn't work with instantsBrain doesn't work with instants☜Neurological studies show that the brain does not work with instants. It works with an extended present (aka specious present) generally thought to be 2 to 3 seconds duration. Given this, it is feasible for the brains working memory to apprehend memory accretion. See also Julian Barbour citation.☜FFFACD

Psychologically, we inhabit a 'specious present' »Psychologically, we inhabit a 'specious present'Psychologically, we inhabit a 'specious present'☜Psychological and neurological studies suggest that we do not perceive events moment-by-moment but rather integrate them into perceptual units of approximately 2 to 3 seconds duration. This results in successive events forming a perceptual unity that can be apprehended without recourse to memory.☜FFFACD

Some weak evidence for entropy clocks »Some weak evidence for entropy clocksSome weak evidence for entropy clocks☜Since Eddingtons time extensive neurological and psychological studies have sought to identify time-keeping mechanisms in the brain. Some hypothesized mechanisms are based on the rate of decay of memories, which would be aligned with the direction of increasing entropy (see citation).☜FFFACD

►

Multiple neural clocks »Multiple neural clocksMultiple neural clocks☜Modern neurology has failed to identify any single neural clock in the human brain. Current evidence suggests the brain has multiple time-keeping mechanisms, specialized to different durations. One proposed mechanism based on the rate of decay of memories may have some relation to entropy.☜FFFACD
