How is Poor Sleep related to Memory Disorder

What You needed to Know about Poor Sleep! 

Maintaining a good night sleep is a very healthy habit. The good night sleep makes way for satisfaction and happiness. Not only that, our productivity is enhanced as well. We can focus our energy better on our goals. Unfortunately the opposite is also true. A night of poor sleep can easily mess up your productivity and performance. Until now, it was pretty vague that how is our brain affected. However, a recent study has shown exactly how and where our brain is affected.

A new research has followed from one of most notable universities of world. One is University of Zurich (UZH), the other one is Swiss Federal institute of Technology (ETH). Both these institutes have set out to find the pattern of disturbed sleep pattern and its effects on anatomy of our brain. Apparently, the first part of brain which is affected is the Centre which deals with learning and cognitive abilities.  

Another study published in a Journal named as, “Nature Communications”, certain abilities of brain are looked upon. Apparently a part which receives stimuli from environment is affected badly. The same part is restored to being fully functional after the deep sleep. This area is called the Motor Cortex.

The motor cortex is the area which deals mainly with motor skills of brain. For a moment, imagine the function of motor. It runs for some time. Then it restarts after we turn it on again after some time.  Similar to that of motor, here the brain is restarted in a manner after a sleep. This motor skill is responsible for memory formation and development. These are the parts of brain which retain information after a whole day is passed. If their functionality is temporarily impaired, your memory function won’t be that good.



Motor Cortex during Sleep

For this experiment, six women and men were selected for study. These people were asked to perform normal daily to daily tasks. Then at night, they were to be subjected to proper sleep.

In a similar manner, they were asked to perform tasks again. However, this time, their deep sleep pattern at night was disturbed.

One of most common activities that they were asked to do were a series of finger movements. The reason for such exercise was that these exercises were controlled by brain part. This brain part was also responsible for memory of learning movement.

The researchers noticed the brain parts deeply by using their equipment. They monitored closely the brain during sleep. The brain was monitored both during deep sleep and disturbed sleep.

On the first day, the participants were allowed to have a sound sleep. They were given a learning session. This session was about finger movements.

On the second day, the sleep of associated people was disturbed. They scientists controlled the quality of sleep to yield results. While the brain parts of all the people were closely monitored, the motor cortex was especially checked. This motor cortex showed a clear difference in performance before and after the sleep disturbance. It showed a difference of performance in practicing the same and newly learned movements.

The day started with few learning sessions of movements taught to the participants. The participants were hyperactive in first few hours of their session. They eagerly learned and practiced correctly. It seemed their hyperactivity was related to sleep deprivation.

As the day progressed, the number of mistakes started increasing. The participants couldn’t focus properly. Silly mistakes were made even in simplest of procedures. The participants did not anticipate this. Yet it was predicted by the researchers.  

This caused the researchers to draw a few conclusions:


1. A night of restorative sleep caused the participants to behave properly. They weren’t hyperactive. In fact, their minds functioned a bit slow in beginning. Yet they functioned properly with fully functional memories as the day progressed.


2. After the night of sleep disturbance, the participants showed hyper activity at first. However, this activity was short lived. As the day progressed, they started showing lack of concentration and memory.


Researchers say that the reason why this happened is because the neurons aren’t functioning properly. In a deep sleep phase, the neurons get enough time to be recharged for the day ahead. However, as the sleep pattern was disturbed, they couldn’t be recharge enough. As a result, hyper activity was depicted. This energy was then short lived.

The part of brain which has been declared responsible is called synapses. The synapses are active during the day or waking hours. These synapses function by getting excited in response to environment around. These excited spikes generate the energy which we use as the day passes.

When our sleep is insufficient, these synapses are not rested enough. When this happens, they get excited too quickly to external environment. When this happens, then the energy is spent too quickly. This energy may appear as hyper activity. As the day passes, the energy has been spent and then comes the phase of fatigue.


Relation of Excited Brain to Learning

The relation of excited brain is direct with learning Centre of brain. When the brain cells are getting excited, proper energy is released for the memory to work.

As the brain cells get too much excited instantly, the memory Centre of brain gets saturated soon. This leads to exhaustion before the process reaches its peak.

The research was conducted again. This time, the researchers tried manipulating another part of brain by some other activity. The results were collected.

This time, there was no difference in performance of participants. Therefore, it was proved that we need our memory Centre to function properly.

The connection between memory effectiveness and sleep deficiency cannot be ignored. It has been proved by scientists that lack of sleep hinders our learning centers. This cause the memory cells to exhaust before they even try functioning properly. Therefore, for good functioning, a proper good night sleep is necessary.
