Decrease in concentration at work at certain times of day? Believe Your Brain

Do not blame for the lack of worry that occurs early in the afternoon for a long meeting or low levels of caffeine.

A new research suggests that brainstorming functions are aligned with the body's daily rhythm, and about 14 hours is a low point for a good sense of solving a major, important task.

Decreasing motivation and functioning after lunch is known to many people, and often results in taking breaks or going to beer.

Scientists from Swinburne University of Technology in Australia have decided to find out how much our desire to perform tasks is related to the natural body-to-day rhythm

Using a capture technique called Function of Functional Magnetic Resonance (fMRI) Depending on Oxygen Volume (BOLD), the team investigated which parts of the brain responded to the feeling of awards at different hours per day in a group of 16 healthy progenitors.

Volunteers were then presented with a task in which they had to guess whether the hidden value of a digital map on the screen was bigger or smaller than five. The exact answer would have made the reward while the inaccurate answer was punished.

To motivate volunteers, the researchers told them they would get a bonus for the best of three trials that were conducted in three different terms; at 10, 14 and 19 o'clock.

Respondents did not know that the task was set so that everyone had the same number of awards and penalties. Each of them took home the same amount of $ 27 in the home.

The observation of their brains during the exercise of the task revealed a pattern of activity in the brain-based structure, called putamen.

This brain tissue thruster manages a series of tasks, many of which involve learning and strengthening behaviors that have the greatest potential for positive outcomes. That he is more prepared in some hours than in others can be interpreted as willing to receive an unexpected prize.

"We found that activation of the left putamena, the reward center located at the base of our front brain, was constantly the lowest in measurements at 2 pm, compared to the beginning and end of the day," said researcher Jamie Byrne. ]

This is in line with their hypothesis, which claims that brain responsiveness varies depending on the same biological rhythm that encourages us to wake up, sleep or feel hunger during the day.

In other words, our brain does not expect the task to be so rewarding in the morning and late in the evening as it is mid-day.

"It is most likely that the brain" expects "rewards in some parts of the day more than in others because it is adjusted to the body clock," Byrne said.

"Data suggests that brain reward centers could be cautious of expecting early afternoon prizes, and" surprised "when prizes appear at the beginning and end of the day."

The research found no evidence to explain why our brain is "naughty" to learn from experience better at the beginning and end of the day. Also, it is a small group of respondents, the rank of men, so there is still room for discussion.

It is possible that it is a time of high risk, when our bodies are tired, hungry or exposed to a greater number of threats.

The brain that is best faced with problems that could bring unexpected awards at certain times of the day could save us time and increase our benefits.

Also, expecting rewards to be easier when conditions are best – mid-day – could preserve precious energy of the brain.

Aside from speculation – research shows that future research needs to be cautious when choosing the days of neurological experiments with rewards.

If you take a brain in the wrong time, the results might be significantly different

For the rest of us, exploration is a nice excuse to afford an extra hour of socializing in the common kitchen.

Just tell your boss that your brain is expecting a better reward.

The research was published in the journal The Journal of Neuroscience .
