"Thus, temporal context is critical for perception, including the perception of causation. The brain “chunks” or segre- gates perceived events according to its ability to package information in time, and such packaging, I propose, can be achieved by neuronal oscillators (Cycles 9 and 11). 
Here is another illustration of a “logical illusion” in which the brain falsely re- constructs the order of events. You are driving on a highway and a deer crosses the road. You slam on the brakes and avoid a collision. The mental reconstruction of the events is as follows. You noticed a deer (cause) and realized that it would be dangerous to hit the animal. So you decide to avoid it, push the brakes, and turn the steering wheel (effects). Laboratory replication of such real-world actions offers a different explanation. A deer appeared (first event), you braked (second event), and then you recognize the animal (third event). This sequence is proposed because reaction time to an unexpected event is less than half a second, whereas conscious recognition requires the recruitment of a large number of neurons in a large, distributed complex brain circuit, which takes longer than half a second.17 The false logic emerges from the difference between external time and brain- reconstructed time."

The brain's ability to perceive time is a process that extremely inherent to human existence, but so rarely understood in its full capacity. It is a process related to prediction, inference, forecast, and deduction in regard to calculating outcomes based on past knowledge. Time is recorded in the brain in order to aid in survival of human beings by learning from the past, and predicting potential danger or success. However, it is easy to apply causal relationships to situations that have discrepancies between external time and subjective time registered in the brain, as described in the quote above. This circumstance raises questions in regard to registering time through the accumulation of past experiences rather than the actual series of events. Additionally, in situations with multiple causes, how can a single source be identified? Many events occur in neuronal oscillations as numerous parts of constantly changing parts, making it impossible to decipher the actual causes. The brain's chunking mechanisms would fail in these circumstances, but are there ways for humans to train their minds to avoid these pitfalls? Could knowledge of the common mistakes in perception allow humans to avoid lapses in judgement in regard to time? Or is the brain essentially an organ that will function to recollect time in the same way? Also, could these lapses in the judgement of elapsed time be related to memory, such as the flaws of memory studied by Proust? The brain's complexity and mystery has been studied for ages, and will continue to be studied for centuries to come.
