There have been many new research tabloids that have extolled the virtues of sleep and how drifting to sleep can trigger one’s memories to relive a past event. This memory-recall process happens in the subconscious terrain of your sleep. This sleep process could reignite forgotten memories by activating the region in the brain called the hippocampus; a region in the brain that comes in handy to bring back to memory or remember the temporary thoughts that are relatively new and this rekindling of thoughts in the hippocampus takes place during one’s sleep process in the subconscious mind. This memory ‘awakening’ during the sleep comes to aid if one is suffering from injuries or help get people back on to track when they are suffering from PTSD (Post traumatic Stress Disorder). Here on both occasions, memory happens to act as a trigger.
Memory at work:
It may have occurred to you that a full at rest brain thinks well and creates an atmosphere conducive for learning and remembering the finer pints and details and come up with the most satisfactory answers. ON the other hand, a weary and sleepy brain that is on the verge of dozing off at any moment is not at all clear headed and is foggy-headed and a well-known trait of a sleepy mind is zero productivity at work.
Sleep as we know it is supposed to bring healthy and constructive thoughts where we are more responsive and allows us to concentrate and fosters transfer of information from one area to another healthy region of the brain.
Researchers have gone and tested the thought process in a person who has slept well and at a time without sleep; after which he is taught a new skill to and scan their brains. With this the result is that a period of good sleep give the users a faster central brain that attributes speed and accuracy which is faster in comparison with people who haven’t slept. SO it can be stated that people who go to sleep after learning a skill have more retentive powers and is able to comprehend the topic extremely well as in contrast to the drowsy counterpart.
Positively good brain after a good night’s sleep:
Thus sleep behaves as a generator of ideas instigated by the brain and slowly passed on to memory which is the hippocampus; that region where temporary memories reside before passing on to the neocortex. This is an activity that takes place in one side of the brain and it is by comparing activities that originate in one side of the brain during sleep and the hemispheres that have activity going on in them, you can disseminate the activity that actually a trauma related to its emotional content.
Sleep also helps us to generate new ideas and not simply remember the old ones. Hence while going off to sleep better piecing together new concepts can be pulled from one area and correlated to the work in hand to give you that special moment when you can afford the gesture of a smile especially when you are trying to come to a conclusion with a problem.
A whiff of a scent to strengthen brain’s ability:
It is known that when recalling agonizing moments, one can fall into a trap easily with most of the post traumatic thoughts coming from the right hemisphere ostensibly connected to its emotional content.
This brain-centric activity which realigns that one’s left hemisphere gets worked up when memory and information is stored in the right brain hemisphere. This takes us to the main underlying notion with this simple experiment that includes a rose. When exposed to a scent of a rose, one found that researchers who put letters on the right and left side for the screen and were told to a jab at remembering the letters from which part of the screen did they orient it to. Then the participants were told to take a nap with the same procedure being reported with a slight difference. The rose was presented to one nostril only. This one-nostril delivery targeted only one side of the hemisphere. It was noted that memory for the words were stronger to the hemisphere on the side of the nostril that was presented the rose than that for the opposite side. So it has been demonstrated that the memory targeting process can be assimilated with external stimuli such as scents that serve as pointers. It has been derived that by posing scents to the olfactory pathways, memories can be distinguished to bring about an awakening in one side of the brain. Thus there is a sleep induced communication between the hippocampus and specific regions in the cerebral cortex.
Refreshing Sleep-wake up Cycle: Experiments
This sleep-awake cycle is an ongoing function and one need to sleep well to channelize his energies in a most fruitful manner and the following experiment will train your olfactory senses to a scent. On waking up his memory will ask him to remember the unnatural sent that will answer the question of that uncanny smell during sleep!
As an afterthought, electric impulses were transmitted to the brain and it was concluded that one-side rose fragrance delivery led to different wave patterns in the two hemispheres. The hemisphere that received the scent was off to a better start with better waveform of memory merging during sleep and the candidates were asked how they felt to the words that will feel after being fed with words to them before falling asleep; The diagnosis: The memory remained true for the better part when words were input to the side affected by smell than memory for words presented on the other side.
A ha! Sleep has a negative downside also! As no sleep or sleep apnea and excessive sleepiness also called hypersomnia when sleepiness occurs in more quantities than acceptable but the malady remains the same. Excessive sleepiness keeps the patient still tired throughout the day. You might sleep well over 10 to 12hours a day but still wake up feeling disoriented. Depending on your sleep routine, the Doctor might ask you to consult a specialist for additional diagnosis.
There is a complicated relationship between sleep, anxiety and depression. Once you do not get your 7-9 hours of quality sleep, it can bring loads o sadness and intermittent spells of sadness and disappointing emotions. It might also take a toll on your robust mood and cherubic health. It can create a rift in your family with people affected by sleep disorders can enter into altercations with family members and there is a high chance of contracting serve depression. Sleep apnea is linked to depression as well with the patient waking up at odd hours during the night.
It has been conclusively researched that good sleep is needed for consolidation of memory and adults display procedural memories and declarative memory- recall of facts. The sleep and memory patterns are not studied so deeply in adolescents. The cognitive disturbances of adolescent sleep is another area of study that needs to be studied in depth. REM sleep and SWS o short –wave sleep are the result of slow but gradual lack of visual location. Declarative memory is more than moderately improved in adolescents.
It can be deduced that a good night’s sleep enables sufficient changes in the brain that helps to foster good memory retaining skills according to a new research led by Beth Israel Deaconness Medical Center (BIDMC).
New memories are formed within the brain when a person engages with new information to be learnt but these memories are weak and need to be bolstered adequately. This is or all to know that memory merging or consolidation occurs when connection between brain cells and different brain regions are developed. This was earlier understood to be developed with elapse of time. This goes to prove that sleep well-deserves the accolades for preserving memory.
For instance, 12 healthy college students were taught a sequence of dexterous finger movements similar to playing a piano scale, After a period of sleep and wake cycle, The subjects were tested on their capability to remember the finger movements while an Magnetic Resonance Imaging (MRI) brought forward the activities going on in the brain.
It was proved without a fault that while some regions of the brain were more active than the rest, others were considerably less active. But good sleep patterns in the individuals got about a sharp improvement in the participants motor performance.
Brain regions imperceptibly yield while sleeping and there is a distinct shift to more proficient regions within the brain, This leads you to get all activities done more easily and with lesser consternation
Procedural skills such as new learnings including talking, limb coordination, musicianship and sports and coherently reading sensory information from the encompassing world become more natural and automatic requiring less conscious thought to be trained.
It should be noted that in a stroke patient’s recuperation, it makes good sense to check sleep disorders and memory disorders to find out if there is any inverse relation between them.
Some scientists have concluded that there is considerable deprivation of sleep-time which is also known as sleep bulimia and busy individuals often neglect sleep during the week and they catch some winks only when the weekends arrive.
Imaging and behavioural studies show the critical role sleep plays in learning and memory.
Researchers are of the view that
Deprivation of sleep disturbs a person’s capability to concentrate and learn productively,
Sleep is needed to make thoughts and ideas remain to relearn in the future. Memories are of different types. Some depend on facts such as memorizing the capitals of states and some are episodic with much thought left to events. Some are procedural or instructional such as learning the violin or riding a bicycle.
Memory consists of three important aspects:
Acquisition: learning something new
Consolidation: the distinctive stability of memory in the brain
Recall: have capacity to avail memory in the future.
