2.3-Time Perception

For many years, researchers have searched all over the body for a center where time is perceived. According to some, this center was the human brain. According to some, it had a center that has not yet been discovered in the depths of the body. But the mistake of the researchers was that they thought that the concept of time was the responsibility of only one place or region…

“We know that there are two groups of cells related to the perception of time in the region of our brain called the frontal lobe. One of them works like a clock, controls time and allows us to stay in the moment we live. The other group of cells helps us in our designs and evaluating the environment; It makes predictions about the results of our designs by enabling us to benefit from our experience. The different perception of time can be explained by the fact that both groups of cells are very close to each other.

In the moment of fear and terror, the brain is alarmed and begins to produce signals in rapid succession. Design cells begin to work at an extraordinary speed to ward off danger. Meanwhile, time warns cell groups. The working efficiency of stimulated time cells increases.

When emitting ten signals per second under normal conditions, the number of signals emitted by the cell group suddenly reaches 20 to 30! The brain has started to work two or three times faster at this moment, and it spends two or three times the normal power in a certain period of time. Time is naturally perceived as longer. (Ubelacker, 2005).

2.3.1-Center of Time and Movement

“Warren Meck and Catalin Buhusi of Duke University in Durham, North Carolina compiled and published the results of these studies. The researchers said that the ‘striatum’, or striatum, which is part of the basal ganglia in the brain, is the center of the timing system. The rate-regulating mechanism cannot be simplified with the “striped body” explanation. Indeed, the researchers note that other parts of the brain, such as the anterior cortex, are also involved in measuring time flow.

Neurons in these areas of the brain coordinate movements, manage the perception of attention, and are recorded in memory records. Again, the same neurons stimulate the striped body with electrical signals. In the striped body, it measures how much time has passed by looking at these landmarks. The random detection model is still under development. however, it is becoming increasingly clear how flexible we measure time by criteria.”*

A specific center of time has not been clearly found despite all the research. There have been significant developments in this regard in recent years. However, it was found out how the perception of time was formed and which regions emerged thanks to its functionality. Some signs showed that the perception of time as a whole is a complex perception that develops under the influence of different components. It was understood that the region where these perceptual activities were concentrated was the small brain (Cerebral or Cerebellum) and basal ganglia.

“This way, they can see the brain while it is working. The increase in blood circulation in a certain area of ​​the brain is considered as a sign that the gray cells in that area are working in particular. This technique has been developing so fast that we have been getting new information about our emotions and thoughts almost every month in recent years” (Klein, 2006) .

To investigate the sense of time, for example, subjects are shown two images appearing in succession on a monitor. A subject is then asked which image appears longer. During this time, the tomograph shows the subject’s brain activity.

Small Brain:

Two parts of the brain are particularly active in almost all of these experiments, and both parts are involved in rhythm and movement. One of the regions that clearly makes a special contribution to the sense of time is the small brain.

The small brain is especially responsible for very repetitive movements, such as when we run, throwing one foot after the other. Thus, while consciousness can turn to something else at the same time, the small brain manages the sequences of commands that reach the muscles from the spinal cord. It would not be possible for us to walk and talk at the same time (Klein, 2006).

Basal ganglia:

The second center, which plays a role in the sense of time, is located in the lower part of the large brain. There are a series of nuclei called “basal ganglia” here. We use this structure especially in complex movements that we do not often do in daily life, for example, when passing a thread through the eye of a needle. They send electrical vibrations that spread to many other centers of the brain through the stations. Thus, a measuring pulse occurs, with the help of which the brain coordinates the cooperation of the muscles (Klein, 2006).
