Both emotion and sleep are independently known to modulate declarative memory. Memory can be facilitated by emotion, leading enhanced consolidation across increasing time delays. Sleep also facilitates offline memory processing, resulting in superior recall the next day. Here we explore whether rapid eye movement (REM) sleep, aspects of its unique neurophysiology, underlie these convergent influences on Using a nap paradigm, measured neutral negative emotional memories, association with...
Background Increasing evidence demonstrates that motor-skill memories improve across a night of sleep, and non-rapid eye movement (NREM) sleep commonly plays role in orchestrating these consolidation enhancements. Here we show the benefit daytime nap on motor memory its relationship not simply with global sleep-stage measures, but unique characteristics spindles at regionally specific locations; mapping to corresponding representation. Methodology/Principal Findings Two groups subjects...
Although the impact of sleep on cognitive function is increasingly well established, role in modulating affective brain processes remains largely uncharacterized. Using a face recognition task, here we demonstrate an amplified reactivity to anger and fear emotions across day, without sleep. However, intervening nap blocked even reversed this negative emotional while conversely enhancing ratings positive (happy) expressions. Most interestingly, only those subjects who obtained rapid eye...
While a role for sleep in declarative memory processing is established, the qualitative nature of this consolidation benefit, and physiological mechanisms mediating it, remain debated. Here, we investigate impact physiology on characteristics episodic using an item- (memory elements) context- (contextual details associated with those learning paradigm; latter being especially dependent hippocampus. Following back-to-back encoding two word lists, each different context, participants were...
Abstract Sports psychiatry is a young field of medicine and that focuses on mental health among athletes, sports exercise within disorders. However, the development its fields activity vary from region to are not uniform yet. role psychiatrists have also already been discussed in medicine, medical teams competitive elite sports. A definition psychiatry, activity, psychiatrist, essential knowledge, skills, abilities ( plus attitudes, eKSA +A ) psychiatrist were developed as part an...
Introduction: Evidence has accumulated, which indicates that, in healthy individuals, sleep enhances procedural memory consolidation, and that spindle activity modulates this process. However, whether sleep-dependent consolidation occurs patients medicated for major depressive disorder remains unclear, as are the pharmacological physiological mechanisms underlie Methods: Healthy control participants (n=17) (n=11) were recruited subjected to a finger-tapping motor sequence test (MST;...
The purpose of the study was to examine whether video modeling (VM) is an effective method for teaching augmentative and alternative communication (AAC) skills children with autism spectrum disorders (ASD). Three ASD participated in study. PlayVimo iOS application used create VM instructional materials. demonstrated how request preferred activities using Proloquo2Go™. An iPad ® present VM. A multiple-probe design across participants investigate effects seven-step task analysis developed...
ABSTRACT In competitive and elite sports, mental health athletic performance cannot be considered separately. Mental disorders in sports are bidirectionally associated with reduced performance. A decline performance, both within outside of sport, can a sign disorder. Additionally, poor is potential risk factor for athletes. The central role psychiatrists play the athletes well‐established. However, their less well‐described more controversial, perhaps due to perception that purely secondary...
In our case report we describe the of a patient who experienced stroke in her left hippocampus that was found following an attempted suicide via glyphosate overdose. To best knowledge this is first to hippocampal infarction associated with drug A 64-year-old Japanese woman brought emergency department after ingestion unknown dose surfactant herbicide order attempt suicide. On admission, she assumed be presenting depression or psychiatric illness, however, sudden-onset memory deficit became...
Background: Overwork, fatigue, and sleep deprivation due to night duty are likely be detrimental the performance of medical residents can consequently affect patient safety.Objective: The aim this study was determine possibility deterioration cerebral function sleep-deprived, fatigued using neuroimaging techniques.Design: Six were instructed draw blood from artificial vessels installed on arm a normal cooperator. Blood drawn at similar time day, before after duty. To assess conditions during...
The effects of repetitive transcranial magnetic stimulation (rTMS) on physical activity and sleep patterns in individuals with major depressive disorder (MDD) remain unclear.We examined the rTMS treatment rest-activity cycle disturbances MDD. In this open-label pilot study, 14 patients medication-resistant MDD underwent 10 sessions over bilateral dorsolateral prefrontal cortex. addition to Hamilton Depression Rating Scale Pittsburgh Sleep Quality Index scores, waist actigraphy was used...
Purpose: To compare the properties of sleep spindles between healthy subjects and medicated patients with major depressive episode, including frequency range, spectra power, spatial distribution spindle power. Methods: Continuous 16-channel EEG was used to record nocturnal in control patients. Recordings were analyzed for changes power topography. Additionally, we graphically demonstrated pattern each type spindle, divided into fast (12.5–14 Hz) slow (11–12.5 Hz). Results: Sleep records...
Severe social withdrawal, called hikikomori , has drawn increased public attention. However, an optimal clinical approach and strategy of treatment not been well established. Here, we report a case for which exercise intervention using jogging therapy was effective, showing cerebral hemodynamic improvement. The patient 20 year old Japanese male who hospitalized in order to evaluate treat severe withdrawal. Although depressive anxiety symptoms partially subsided with sertraline alone,...
To investigate the prevalence and characteristics of depressed patients living in a Japanese leprosarium who have been isolated by national law are now becoming very elderly.We surveyed National Tamazenshouen Sanatorium, major Japan. We also investigated had suffered depressive episode during last 5 years (2000-2004). The residents committed suicide were studied.At time investigation, 48 out 385 (12.5%) or experienced episode. Forty-one since was established 1907. Somatic symptoms moods...
<b><i>Background/Aims:</i></b> Modified rock, paper, scissors (RPS) tasks have previously been used in neuroscience to investigate activity of the prefrontal cortex (PFC). In this study, we investigated hemodynamic changes PFC using near-infrared spectroscopy (NIRS) during a modified RPS task which each subject's successful performance rate was equalized; workload increased parametrically order reveal resulting pattern activation....
Abstract This study explored the effect of long naps on handball-related performance and assessed role cardiac autonomic nervous system in this process. Eleven male collegiate handball players performed a repeated sequential trial consisting 20-m consecutive turnaround run, 10-m run with load, shooting ball into target. Participants were allocated randomly sequentially to have short (20 minutes) nap, (60 or no nap. The Pittsburgh Sleep Quality Index was used assess regular sleep quality....
Abstract Here, we report a case of rapid eye movement sleep behavioural disorder in an elderly patient with dementia Lewy bodies. Pretreatment polysomnography revealed atonia during sleep, absence spindles and loss slow‐wave sleep. Administration donepezil, acetylcholinesterase inhibitor, markedly improved delusional symptoms cognitive function. performed after donepezil administration considerable number spindles. The effects cholinergic modulation induced by seemed to cause remarkable...
Delayed encephalopathy (DE) affects not only the cerebral white matter and globus pallidus but also cortex thalamus. However, it remains unknown whether these brain lesions alter sleep along with clinical manifestations of DE. A 46-year-old man DE underwent repetitive hyperbaric oxygen therapy. The patient was evaluated by neuropsychological neuroimaging testing polysomnography over course. Neurological symptoms improved markedly; however, profound frontal cognitive deficits continued....
