I don't know that this is the source of the seeming speeding up of time as we age,
or it might be one of several [many?] contributing factors, but i will throw out a notion for others to give their alternate, concurring or tangent perspectives on.

Mechanism Found That Prepares the a Newborn's Brain for Information Processing
16 May 2010

. . .
The brain cells in the
brain of a newborn are still quite loosely interconnected. In the middle of chaos, they are looking for contact with each other and are only later able to operate as interactive neural networks.

Many
cognitive operations, such as attention, memory, learning and certain states of sleep are
based on rhythmic interactions of neural networks. For a long time the researchers have been interested in finding the stage in the development of the brain in which the functional characteristics and interconnections are sufficiently developed for these subtle brain functions.

Key players in this maturation process include a type of nerve cells called
interneurons, and recent research sheds light on their functional development. The researchers have noticed that the activeness of the
interneurons change dramatically during early development. In the memory center of the brain they found a mechanism which adjusts changes in the activeness of interneurons.

The interneurons nerve cells are kind of controller cells. In the nervous system of a newborn they promote the creation of nerve cell contacts, and on the other hand
[Interneurons] prevent premature rhythmic activity of neural networks. During development the controlling
role will change, and the result is that the neural network becomes
more efficiently rhythmic.
This can be seen, for example, in the strengthening of the EEG signal during sleep.

The mechanism adjusting the activity of the interneurons is related to the development phase which prepares the brain to process and handle information needed later in life. The finding may also offer more detailed means to intervene in the electric disorders of developing neural networks, such as epilepsy.

If the young [human?] brain is embedded in chaos it must find its way through all the confusing sensory input. Even if it develops to have sort of a unified wet blanket [like surface pond scum] over the top of irregular, complex highs & lows it still would have a great deal of 'frictile' [attention scattering] characteristics.
Only as the brain mechanizes, systemizes functions as vastly simpler actions of abstractions does it all become maximally efficient in its processing,
but keep in mind this excludes what its training indicated was noise, which ultimately in some cases may not be.

In any event it is sort of the maximal surface area & complexity of that surface that the brain either filters for or doesn't to whatever degree that change our perception of the speed of time.

It is like immersion. If a load is sunk/embedded in water a tow boat has a hard time pulling a load. If it skims the surface like a water skier it becomes much easier. If it takes wing on a parasail its friction is further reduced.
So it may be the ease with which our minds abstract/simplify that changes our perception of time.
But we can't forget that we may miss out on a lot of interesting/useful things that are submerged in the water by skimming or flying.
A friction-drag kind of thing.

It also means we may filter out very subtle or refined available perceptual input.
Maybe mental survival demands some of this, but logically one may need to more careful in weighing & measuring what is or is not included.

The young brain is doing maximal detailed immersion dredging of sensory stimulus. [like a fishing net?]
The older brain steps/leaps/jumps across things more & more.
[the holes get bigger so it only snags the big tuna or sharks? the young one may still capture sardines? small birds?]

In an odd sense it may be our interaction with the discrete plank length that has us lodging in this Universe for some duration of time, but that is admittedly quite a logic leap.

Conceptually speaking it is a kind of engineering. Even if Interneurons don't have much/anything to do with the changing perception of time-speed, i think the general theory may still hold for whatever is making that perception alteration.

Another note of caution: Rhythmic brain waves i think are associated with debilitation & death, so in the case of the brain chaos may be the healthy order. Both in holding polydimensionality as well as accessing fraction unit details.

And that is my weird odd thinking for today.
