Mental clocks and neurology
Question
1
#109308
Does modern neurology shed any light on the hypothesis that the human brain contains internal time-keeping mechanisms? Do any of these correspond to Eddington's hypothesized 'entropy clock'?

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

The experience of time
The experience of time☜This branch of the map considers the phenomenology of time - the various ways in which time presents itself directly to our consciousness. Why do we think time has the features indicated by the passage view? The answers will hopefully enable us to connect the phenomenological to the physical.☜FFB597

Passage view components
Passage view components☜The passage view refers to three aspects of how we perceive time - that it flows, has a direction and that there is a distinguished present moment - and claims that each corresponds to a feature of the real world. These matters are considered in this part of the map.☜FFB597

Flow and direction of time? »
Flow and direction of time?
Flow and direction of time?☜What underlies our sense that time flows - that there is a continuous process where the future is realized in the present and then recedes into the past? Are we directly observing a feature of the real world through the private door of consciousness (Eddington) or is something else going on?☜FFB597

Memory accretion hypothesis »
Memory accretion hypothesis
Memory accretion hypothesis ☜At all times we are aware of a stock of memories of an ordered succession of events, each with a rough or precise time-stamp. We are also aware that the stock is being constantly added to - a process of accretion. This gives rise to the sense of time flowing in the direction that memories are added.☜59C6EF

Direction is that of memory accretion »
Direction is that of memory accretion
Direction is that of memory accretion☜By convention, we identify the forward direction of the psychological arrow of time is with the direction in which our stock of memories grows.☜9FDEF6

Why aligned with thermodynamic arrow?
Why aligned with thermodynamic arrow?☜If memory accretion accounts for the psychological arrow of time, why are the psychological and thermodynamic arrows aligned. We dont recall instances of eggs unscrambling or shattered glass spontaneously re-assembling. Why is this so?☜FFB597

Entropy clocks in the brain »
Entropy clocks in the brain
Entropy clocks in the brain☜Eddington hypothesized that our perception of the direction of time aligns with the thermodynamic arrow because our brains contain entropy-clocks that align the psychological and thermodynamic arrows.☜59C6EF

Multiple neural clocks »
Multiple neural clocks
Multiple 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.☜59C6EF
