The objectives of the present study were to evaluate impact a single bout high-intensity aerobic exercise on 1) long-term potentiation (LTP)-like neuroplasticity via response paired associative stimulation (PAS) and 2) temporal spatial components sequence-specific implicit motor learning. Additionally, relationships between exercise-induced increases in systemic brain-derived neurotrophic factor (BDNF) PAS learning evaluated. Sixteen young healthy participants completed six experimental...

Introduction There is evidence for beneficial effects of acute and long-term exercise interventions on several forms memory, including procedural motor learning. In the present study we examined how performing a single bout continuous moderate intensity aerobic would impact skill acquisition retention in young healthy adults, compared to period rest. We hypothesized that improve retention, practice alone. Materials Methods Sixteen adults completed sessions or seated rest were immediately...

Diffusion tensor imaging (DTI)-based tractography has been used to demonstrate functionally relevant differences in white matter pathway status after stroke. However, it is now known that the model insensitive complex fiber architectures found vast majority of voxels human brain. The inability resolve intra-voxel orientations may have important implications for utility standard DTI-based tract reconstruction methods. Intra-voxel can be identified using novel, tensor-free approaches....

Acute aerobic exercise facilitated long-term potentiation-like plasticity in the human primary motor cortex (M1). Here, we investigated effect of acute on cerebellar circuits, and their potential contribution to altered M1 healthy individuals (age:<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mn fontstyle="italic">24.8</mml:mn><mml:mo>±</mml:mo><mml:mn fontstyle="italic">4.1</mml:mn></mml:math>years).

In previous work, acute high-intensity aerobic exercise benefited continuous motor sequence task learning. As memory processes underlying learning vary between tasks involving and discrete movements, the objective of current study was to determine whether beneficial effects generalize a task.Sixteen young healthy individuals practiced preceded by either period rest or bout cycling. Participants moved cursor with computer mouse series discretely presented targets on screen. Target...

Transcranial magnetic stimulation (TMS) is a non-invasive method used to investigate neurophysiological integrity of the human neuromotor system. We describe in detail, methodology single pulse TMS protocol that was performed large cohort people (n = 110) with multiple sclerosis (MS). The aim establish and validate core-set variables predicted typical MS clinical outcomes: walking speed, hand dexterity, fatigue, cognitive processing speed. provide brief simple methodological pipeline examine...

Emotion regulation is the process of monitoring and adjusting emotional responses to environmental stimuli stressors. Evidence suggests that individuals who participate in physical activity are less likely have an adverse response a potentially stressful situation. The practice yoga form may lessen individuals' levels stress anxiety, improve emotion regulation. Measuring heart rate variability (HRV) brain using noninvasive functional magnetic resonance imaging (fMRI) provides robust...

• A case of Ludwig's angina dissected along deep cervical fascial planes into the mediastinum caused a virulent mediastinitis and abscess. Computed tomography precisely delineated extent infection. Incomplete débridement resulted in residual abscess persistent systemic sepsis that culminated patient's death. Aggressive antibiotic treatment orofacial cellulitis with complete mediastinal drainage are recommended for optimal outcome. (<i>Arch Otolaryngol</i>1983;109:53-55)

Abstract The objective of the current work was to evaluate whether effects acute aerobic exercise on motor learning were dependent genetic variants impacting brain-derived neurotrophic factor ( BDNF val66met polymorphism) and dopamine D2 receptor DRD2/ANKK1 glu713lys in humans. A retrospective analysis performed determine these polymorphisms influence data from our two previous studies, which both demonstrated that a single bout prior practice enhanced implicit learning. Here, main finding...

ABSTRACT Introduction The interactive effect of delayed-onset muscle soreness (DOMS) and a topical analgesic on corticospinal excitability was investigated. Methods Thirty-two participants completed Experiments A (no DOMS) B (DOMS). For each experiment, were randomly assigned to two groups: 1) gel (topical analgesic, n = 8), or 2) placebo (placebo, 8) group. Before the application (pregel), as well 5, 15, 30, 45 min postgel, motor-evoked potential (MEP) area, latency, silent period,...

Persons with multiple sclerosis (MS) frequently report pain that negatively affects their quality of life. Evidence linking and corticospinal excitability in MS is sparse. We aimed to (1) examine differences participants without (2) explore predictors pain.Sixty-four rated severity on a visual analog scale (VAS). Transcranial magnetic stimulation (TMS) validated clinical instruments characterized subjective disease features like mood fatigue. retrieved information participants' prescriptions...

Despite the abundance of barefoot running-related research, there have been no electromyography studies evaluating effects this mode exercise on habitual users minimalist footwear. The present study investigated differences in muscle activation during acute bouts and shod running, shoe users. 8 male participants ran a motorized treadmill for 10 min under both conditions, at 70% maximal aerobic speed. Electromyographic data were sampled from biceps femoris, gluteus maximus, gastrocnemius...

We examined the effects of attentional focus cues on maximal voluntary force output elbow flexors and underlying physiological mechanisms. Eleven males participated in two randomized experimental sessions. In each session, four blocks three contractions (MVC) were performed. The consisted externally internally cued blocks. one sessions, corticospinal excitability (CSE) was measured. During stimulation session transcranial magnetic, transmastoid Erb’s point stimulations used to induce motor...
