Filter by:Purpose: The purpose of this pilot study is to investigate the dynamics between theta and alpha oscillations in the control of working memory. These findings will be informative of what types of brain stimulation are most effective at modulating brain activity. Deep brain stimulation and transcranial magnetic stimulation are used for an increasing number of neurological and psychiatric disorders. Participants: Eligible participants are patients who have previously had electrodes implanted to monitor epilepsy (outside of research activity). 50 participants will be recruited, 25 participants for each phase of the study. Procedures (methods): The participants will perform a cognitive control task. During the task, rhythmic trains of direct cortical stimulation will be delivered to the frontal cortex alone or to the frontal and parietal cortex. Electrocorticography will be collected concurrent with stimulation.
This study will use novel transcranial alternating current stimulation (tACS) protocols and electroencephalography (EEG) to modulate and measure brain oscillations that underlie working memory. tACS is a noninvasive method used to modulate the timing and patterns of brain rhythms via weak electric currents passed through electrodes on the scalp.
This study uses different types of functional magnetic resonance imagining (fMRI) to generate individual transcranial magnetic stimulation (TMS) targets. During the TMS/fMRI imagining sessions, the investigators stimulate a target of either high or low regional controllability during a working memory task to investigate network responses and the impact of TMS on behavior.
In recent years, sports have become popular, and major gyms or private exercise studios have been opened continuously. A dazzling array of course content allows students to choose according to their preferences. Therefore, how to improve students' compliance with gyms or classrooms, and increase exercise frequency to develop exercise habits , is the current problem faced by the industry. However, in the case of limited time, the academic side is looking for more effective training courses, and the industry side is trying a variety of courses that are more attractive to the public, hoping to be different from the previous types of sports, improve the motivation of public sports, increase the frequency of exercise and then Maintain exercise habits. Compared with aerobic dance, boxing, yoga and Pilates, ballet is a niche course, but more and more studies have pointed out that ballet can effectively improve posture, improve lower limb muscle strength, and improve cognitive, executive memory, and working memory. Therefore, this study intends to explore the effect of ballet courses on lower limb explosiveness, static balance, dynamic balance, cognitive executive function and working memory of exercise studio students. degree and become one of the courses chosen by students for their classes.
This study aims to examine whether listening to natural sounds in a noisy outdoor environment compared to no natural sounds influences behavioural, cognitive, affective, and physiological markers.
This study aims to examine whether listening to natural sounds in a noisy virtual reality environment compared to no natural sounds influences physiological markers.
Working memory (WM) deficits are a transdiagnostic feature of adolescent psychopathology that substantially contribute to poor clinical and functional outcomes. This proposal will utilize a multimodal neuroscientific approach to investigate whether non-invasive brain stimulation can modulate the neural mechanisms underlying adolescent WM deficits. Directly in line with NIMH priorities, the researchers will identify the contributing roles of prefrontal and parietal regions in WM processes, as well as identify optimal targets and parameters for novel brain-based treatments in adolescent psychopathology. This study is funded by the NIMH-K23
This study will assess the impact of traveling wave transcranial alternating current stimulation (tACS) on working memory performance in adults.
Establishment of effective, efficient, and evidence-based interventions in rehabilitation of working memory (WM) deficits after acquired brain injury (ABI) is sorely needed. Despite robust evidence for the usefulness of clinical hypnosis in a wide range of clinical conditions, and improved understanding of mechanisms underlying it ́s effects, the potential of clinical hypnosis in cognitive rehabilitation is virtually unexplored. The current study seeks to replicate resent intriguing findings where large effects of hypnotic suggestion were seen on WM capacity following ABI, and further, explore underlying mechanisms of change.
In genome-wide association studies we identified potassium channels to be genetically linked to performance and neural activity of working memory in healthy humans. Furthermore, there is evidence in rodents and non-human primates that pharmacological blockade of potassium channels can improve working memory. In the present study, we aim at investigating the effects of 10 mg fampridine (4-Aminopyridine), a potassium channel-blocking agent, on working memory performance in individuals with Post-COVID-19-Condition with subjective cognitive impairment. The hypothesis is that fampridine improves working memory performance. Fampridine, especially its slow-release formulation (Fampyra®) is generally a safe drug with well-studied pharmacokinetic properties. It crosses the blood-brain barrier and reaches maximum concentration in the brain approximately 3.5h after single-dose administration. Evidence suggests that fampridine improves walking speed in patients with multiple sclerosis (MS), which led to FDA and EMA approval for this indication. The mode of action by which fampridine improves walking speed is probably its blockade of a spectrum of potassium channels that are exposed in demyelinated axons, leading to mitigation of potassium leakage and normalization of nerve conduction. Additionally, an action of fampridine at central synapses and increase of neurotransmitter release has been discussed.
