Summary: Sleep deprivation inhibits brain regions accountable for suppressing unwelcome thoughts, contributing to psychological health problems. In sleep-deprived people, useful neuroimaging revealed increased synaptic activity and decreased activation in the prefrontal cortex, suggesting memory control issues.
In reviving these mental systems, REM sleep assists in enhancing the capacity to deal with ingrained memories. These results offer new insights into how mental health and poor sleep relate to one another and provide suggestions for prevention and treatment.
Important Information:
- Memory Control Deficits: Sleep deprivation weakens cerebral cortex activity, leading to complexity ignoring intrusive thoughts.
- REM Sleep’s Role: More Sleep sleeping enhances the frontal cortex’s ability to manage undesirable thoughts.
- Mental health effects: Bad sleep, personal dysregulation, and mental health conditions are linked by impaired memory control.

According to research from the University of East Anglia ( UEA ), the link between poor sleep and mental health issues may be related to brain regions that prevent unwanted thoughts from coming to mind.  ,
The origin and preservation of many mental health issues are unknown, but sleep issues play a significant role.
A new study, published in , Proceedings of the National Academy of Sciences , ( PNAS ), offers fresh insight into the cognitive and neural mechanisms underlying the connection between sleep and mental health.
These results could lead to the development of novel therapies and avoidance techniques for mental health conditions like depression and anxiety.  ,
Dr Marcus Harrington, a Lecturer in UEA ‘s , School of Psychology, is lead author of the paper ‘ Storage power imbalances in the sleep-deprived human brains’. He worked with colleagues at the universities of York, Cambridge, Sussex, and Queen’s University ( Canada ).  ,
Utilizing functional neuroscience, it was first demonstrated that difficulties in engaging brain regions that inhibit memory searching, and that over regeneration of these mind regions is linked to rapid eye movement ( REM) sleep, are related to memory loss.  ,  ,
Dr Harrington said:” Memories of distressing experiences may enter into conscious recognition, usually in response to memories.  ,  ,
For those who suffer from mental health disorders like depression, stress, and post-traumatic stress disorder, quite aggressive memories can be repeated, vivid, and upsetting.  ,  ,
Memory power failures may contribute a lot to explaining the connection between sleep loss and personal dysregulation given that memories play a key role in our emotional perception of the outside world.  ,
A better understanding of the mechanisms that cause aggressive memories is essential to enhancing mental well-being and reducing the prevalence of mental illness globally. ”  ,
85 healthy adults used functional MRI to capture images of their brains in an effort to reduce unnecessary memories. Half of the participants slept in the sleep lab the night before the activity, while the other quarter slept through the night.  ,  ,
During storage destruction, the well-rested individuals showed more stimulation in the right dorsolateral prefrontal cortex—a brain area that controls emotions, actions, and emotions—compared to those who stayed awake all night.
In addition, the resting participants ‘ attempts to suppress unnecessary thoughts also showed decreased activity in the hippocampus, a brain region responsible for memory retrieval.  ,
Those who spent more time in REM sleep were more able to engage the right dorsolateral prefrontal lobe during memory loss, which suggests a role for REM rest in restoring cerebral control systems that support the ability to prevent unnecessarily enter conscious thought.  ,
Taken together, Dr. Harrington said,” Our findings emphasize the crucial role that sleep plays in maintaining control over both our thoughts and continued ideas. ”  ,

Abstract
Storage power imbalances in the sleep-deprived human brains
Although overbearing memories are associated with sleep disturbances, the cognitive mechanisms underpinning this marriage are poorly understood.
We demonstrate that time spent in rapid eye movement ( REM) sleep is associated with the disruption of prefrontal inhibition of memory retrieval and that the overnight restoration of this inhibitory mechanism is related to this.
A behavioral gap in the ability to downregulate unnecessary thoughts and sleep deprivation are related to the practical deficits that result from a lack of intentional self-generated thought.
We come to the conclusion that sleep deprivation causes intrusive memories by disrupting neural circuits that govern mnemonic inhibitory control, which may depend on REM sleep.
