Mixed Vs Blocked Search: Four Unique Tasks
NCT06933693
Recruiting
The goal is to look for qualitative differences in visual search behavior when one search is performed many times in a row compared to when multiple search tasks are intermixed. Four search tasks are tested. In the Mixed condition, the four tasks are randomly changed from trial to trial. In the Blocked condition, each task is run as a block of 100 trials.

Experiment 2: One Target in Many Situations
NCT06934148
Recruiting
The goal is to look for qualitative differences in visual search behavior when one search is performed many times in a row compared to when multiple search tasks are intermixed. Four search tasks are tested. The target is the same in every task but the types of distractors change from task to task. In the Mixed condition, the four tasks are randomly changed from trial to trial. In the Blocked condition, each task is run as a block of 100 trials.

Dinner Time for Obesity and Prediabetes
NCT05745441
Recruiting
Obesity and its metabolic complications are leading causes of global morbidity and mortality. Evidence is mounting that inappropriate timing of food intake contributes to obesity. Specifically, late eating is associated with greater weight gain and metabolic syndrome. However, the mechanism by which late eating harms metabolism is not fully understood but may be related to mis-timing of food intake in relation to the body's endogenous circadian rhythm. Conversely, harmonization of eating timing... Read More

The ENHANCE Study: taVNS and Psilocybin
NCT05866471
Recruiting
This study will examine whether combining a single dose of psilocybin with non-invasive transcutaneous auricular vagus nerve stimulation (taVNS), a potential inducer of neuroplasticity and enhanced memory formation, will enhance the long-term beneficial behavioral effects of psilocybin when compared to sham taVNS or no VNS by allowing memory for insights gained during the psychedelic experience to remain vivid after they will have faded in subjects who receive psilocybin followed by sham taVNS o...

Hyperpolarized 129Xe MRI Lung Health Cohort
NCT05766384
Recruiting
A subset of young adults participating in the American Lung Association (ALA) Lung Health Cohort (LHC) will be imaged using Hyperpolarized 129Xe MRI to assess lung structure and function. Images will be used to improve the understanding of lung health and early lung abnormalities that may lead to chronic lung disease.

Effect of Sex on Orthostatic Intolerance and Cardiovascular Response During Lunar Descent and Ascent
NCT06467825
Recruiting
The purpose of Lunar OI (Orthostatic Intolerance) is to determine if there are differences between males and females in tolerance to and cardiovascular responses during different angles of head-up tilt simulating gravity levels less than or equal to Earth's gravity. Also, this study will determine if a gradient compression garment affects tolerance to tilting and the cardiovascular stress at different tilt angles. Males and females are being identified by biological sex. This will be a two-phase... Read More

LPFC Organization in Emotion-Duration Difference Estimation
NCT06276400
Recruiting
To support optimal behavior in daily life, goals and responses following emotional events should ideally incorporate not only the valence and intensity of prior emotional episodes but also their temporal features, such as the relative duration of positive vs. negative attributes. However, how specific brain regions contribute to the integration of temporal and emotional information and promote goal-directed response remains unknown. The goal of this study is to examine how specific brain region... Read More

Non-invasive BCI-controlled Assistive Devices
NCT05183152
Recruiting
Injuries affecting the central nervous system may disrupt the cortical pathways to muscles causing loss of motor control. Nevertheless, the brain still exhibits sensorimotor rhythms (SMRs) during movement intents or motor imagery (MI), which is the mental rehearsal of the kinesthetics of a movement without actually performing it. Brain-computer interfaces (BCIs) can decode SMRs to control assistive devices and promote functional recovery. Despite rapid advancements in non-invasive BCI systems ba... Read More
