Reducing intake from large portions is of critical importance to preventing obesity. People consistently eat more when they are served larger portions, a phenomenon known as the portion size effect. The mechanisms of the portion size effect are not well understood, and investigating the underlying neurobiology that drives this phenomenon may inform the development of more effective obesity prevention programs. The proposed research will follow healthy weight children who vary by family risk for obesity to identify the neurobiological and appetitive traits that are implicated in overeating and weight gain during the critical pre-adolescent period. We expect results to confirm the hypothesis that reduced function of brain inhibitory pathways and increased activity in brain reward pathways in response to portion size cues contributes to excess intake with large portions and greater weight gain over time, particularly in children who have higher risk for obesity. The proposed studies will characterize the relationship between brain response to portion size and eating behavior and will allow us to determine whether brain and behavioral responses predict body fat gain during pre-adolescence. These studies will contribute essential information to our understanding of the pathways implicated in overeating and obesity and will facilitate the characterization of “at risk” phenotypes that can be targeted by prevention programs.

There will be seven in person visits with two DEXA measurements, one fMRI scan and five meals.

This research is being done to help us better understand the risk factors and protective factors for cognitive decline in people who are at increased risk for dementia. The goal of the study is to establish a data and biorepository for people at increased risk for dementia.

Eligible patients for the study, in addition to routine clinic visits, may undergo a series of questionnaires and blood testing.

A brain-computer interface (BCI) is a device that has the potential to restore communication by direct translation of brain signals. The BCI used in this study, the P300 Speller, relies on the generation of a P300 evoked potential when a user is presented a rare and unpredictable target stimulus amidst a larger pool of non-target stimuli. This evoked potential is used to perform selections on the computer. Those with advanced ALS demonstrate decreased capacity for BCI control using the P300 speller. With this study, we aim to use a combination of eye tracking and sensory testing to quantify sensory and cognitive processes necessary for the generation of a P300 response. We will test the performance of a multisensory P300 spelling task, where brain potentials are evoked using a combination of visual, auditory, and tactile stimuli. The goal is to demonstrate the perceptual benefits of multisensory integration and generate evidence for its use in this patient group.

The purpose of this research study is 1.) to determine if Parkinson’s Disease (PD) causes changes in the way that people sense the movements of and forces produced by their bodies, and to connect any of these changes in sensation to changes in the brain, and 2.) to identify how changes in movement might come from different parts of the nervous system. This study will use a combination of electromyography, via electrodes placed on the skin, and finger force recordings to infer how PD affects patients' sense of force production, and the neural mechanisms underlying this change.

This study requires a single in-person visit. We will use adhesive skin sensors on the forearms to measure muscle activity. At the same time, we test the participant's finger strength and then ask them to press with moderate force on piano-key-like sensors. Participants will be asked to match force levels between hands and to move an on-screen cursor into a target.

The Muscular Dystrophy Association (MDA) wants to collect information about individuals with neuromuscular disease to better understand the disease progression and ultimately improve the medical care, quality of life, and survival of those with neuromuscular disease. To collect this information, MDA has created a data registry called the Neuromuscular Observational Research Data Hub (referred to as the “MOVR Data Hub”). The MOVR Data Hub is a kind of database — a way of collecting and storing information.

Each person who participates in the MOVR Data Hub will have his/her information collected for as long as the person is being seen at an MDA Care Center and information is still being collected, unless and until the person requests that the information no longer be provided to the MOVR Data Hub.

The purpose of this study is to define how eye movements contribute to eye-hand coordination in individuals of the age group 18-50 (young adults) and 65-80 (older adults). Specifically, the aim of the study is to understand how slow eye movements affect arm and hand movements. All procedures to be used in our study will be non-invasive. The task during the study will be performed with a robotic handle that participants will grasp with their right hand. They will interact with visual stimuli by moving the robotic handle. The robotic environmentwill attempt to simulate real-world mechanical interactions, such as those experienced during catching a ball.

During this study, we will ask you to come to our laboratory located in 23 Recreation Building,Pennsylvania State University, on two days separated by a maximum of 48 hours. Both sessions will last approximately 90-120 minutes. During the first session, we will review the procedures with you and if you agree to participate, you will sign this form and then proceed to perform the study. You will perform about 20-25 blocks of hand movements. Each block will consist of 24-30 trials and each trial will last between 3-5 seconds.The second day will be identical to the first day but the order of trials within a block will be changed.

This study examines how each brain hemisphere contributes to motor control and coordination. Participants play virtual reality/computer games to look at how their arms move during different activities.

This study will look for emerging patterns of Frontotemporal Lobar Degeneration (FTLD), an early onset dementia, in Juvenile Myoclonic Epilepsy (JME). JME is a type of epilepsy that usually begins in adolescence and is known to be associated with disturbances of higher-level reasoning, mood and personality. JME patients are often managed by family physicians, rather than epilepsy specialists; with little known about aging with JME. We think that JME patients will demonstrate a pattern of executive dysfunction that is consistent with consensus criteria for FTLD, characterized by declines in abstract reasoning, judgment, and verbal problem solving, as well as behavior. We also think that there will be an inverse relationship between apathy and conscientiousness. We plan to obtain this information by formal cognitive testing of non-demented JME patients over a period of 2 years, at 6-month intervals, to look for progression of symptoms. Loved ones/caregivers will complete informant questionnaires about patient's mood and personality at the beginning of the study and at 6 month intervals throughout the duration of the 24 month study. We will also include loved one/caregiver cognitive testing at the beginning of the study to obtain healthy information for comparison to patient's findings. Our objectives are to characterize the executive functioning profiles of JME in midlife, taking into account cognition, mood, personality, nutritional status and lifestyle. The information obtained may contribute to better care of JME patients prior to midlife and throughout the course of aging.

Visit 1 for both patient and healthy caregiver participants will involve administration of the JME Virtual Visit Protocol via PSH Zoom. Participants will have completed their REDCap questionnaires prior to the visit to the research coordinator, who will be conducting the assessment. Visit 2-5 for patient participants will involve administration of the JME Virtual Visit Protocol via PSH Zoom. JME participation consists of 5 virtual visits with the study’s research coordinator, lasting approximately two hours each, for completion of standardized tests of problem-solving, thinking, and concentration, as defined above. Caregiver healthy control participation consists of 1 virtual visit with the study’s research coordinator, lasting approximately two hours, for completion of standardized tests of problem-solving, thinking, and concentration, as defined above. Remaining participation involves completion of objective inventories providing a caregiver perspective of the patient participant’s mood and behavior at 6-month intervals, within the 24 month time frame of the study.

This research is being done to study the deterioration of the central olfactory system (sense of smell system) in the brains of patients diagnosed with early- stage Parkinson’s disease.

In this project, participants will perform experiments where they will be asked to look at salient virtual targets and make reaching movements to those targets, while ignoring other visual stimuli presented to them.

During this study, we will ask you to come to our laboratory located in 23 Recreation Building, Penn State University, on a single day.We will ask you to perform an eye-hand coordination task using a robot. You will sit in a modified chair and grasp a handle that permits you to move your hand leftward, rightward, towards and away from your body. A display system will project visual targets into the same plane as your hands, which will allow you to interact virtually with the visual targets. These targets will be either bright or dark and you will be instructed to look at some of these targets (while ignoring others) and make reaching movements to some of these targets.

Parkinson’s disease and a number of similar conditions, such as progressive supranuclear palsy and multiple system atrophy, often look very similar clinically, particularly early in the disease. Since there is no objective way to diagnose these disorders definitively, the current practice is to follow patients over time to allow the disease to reveal itself. Evidence indicates, however, that even the best movement disorder specialist can provide the wrong diagnosis approximately 25 percent of the time. This lack of diagnostic certainty has limited both clinical practice and research. The goal of this longitudinal study is to determine whether specific MRI and biofluid measures, such as proteins in blood and cerebrospinal fluid, can help better diagnose Parkinson’s, progressive supranuclear palsy and multiple system atrophy patients.

Participants are asked to complete a screening, baseline and 12-month visit. During the baseline and 12-month visit, participants are asked to complete some questionnaires as well as a fasting blood draw, motor evaluation, smell test and MRI. Participants also may choose to complete additional study components that ultimately may guide the diagnosis, prognosis and treatment of Parkinson's and its related disorders. These optional components include skin punch biopsies, a lumbar puncture and participation in the Translational Brain Research Center's brain donation program.

A brain-computer interface (BCI) is a device that has the potential to restore communication by translating voluntarily controlled brain signals of intent. The P300 speller, a popular BCI paradigm, relies on the generation of a P300 evoked potential when a user is presented a rare and unpredictable target stimulus amidst a larger pool of non-target stimuli. This evoked potential is used to control a spelling interface. Those with advanced ALS experiencing the loss of voluntary muscular control may also experience cognitive changes that result in decreased capacity for BCI control using the P300 speller.With this pilot study, we aim to validate the performance of a combination of eye tracking and standard sensory testing to quantify intact sensory and cognitive processes necessary for the generation of a P300 response. Additionally, we will evaluate the association of these correlates with performance on a multisensor P300 spelling task, where brain potentials are evoked using a combination of visual, auditory, and tactile stimuli. The goal is to demonstrate the viability of this system for future use in a patient group.

Inhalation of welding fumes has been known to cause tremor, muscle rigidity and abnormal gait similar to what is seen in Parkinson's disease. Previous studies by the Translational Brain Research Center have used measures such as brain MRIs and tests for movement and function to investigate the effect of these welding fumes on brain health in active welders. The center is currently expanding its efforts to investigate brain health in retired welders.This is an independent study sponsored by the National Institute of Environmental Health Sciences, with no affiliation to any private entities such as law firms.In this study participants will be asked to undergo clinical tests (blood draw, motor examination, memory tests), complete lifestyle questionnaires, and undergo an MRI scan during a baseline and 18 month follow-up visit. Participants also will be mailed a welding exposure questionnaire to complete every three months between their baseline and follow-up visit.

Participants will attend a screening call with the study team, an in-person baseline visit and an in-person follow up visit (at 18 months).

Postural tachycardia syndrome (POTS) is a chronic syndrome in which the heart beats too quickly when standing. POTS primarily affects young women. People with POTS also experience symptoms such as feeling faint, fatigue, nausea, and mental clouding or "brain fog." “Brain fog” is one of the most bothersome symptoms of POTS and it is unknown why people with POTS experience this symptom. Some studies have shown that POTS patients have problems with attention, memory and executive function (ability to plan, organize information, and adapt to changes) while seated and when upright. In this study, we will evaluate how brain function during mental tasks is affected in people with POTS compared to healthy volunteers. All volunteers will complete mental tasks while lying down and standing. If eligible, we will measure brain activity using functional magnetic resonance imaging (fMRI).The findings from this study will increase our understanding of the mental complaints in people with POTS, to hopefully help with development of new treatments.

There will be three in person visits for this study. At the screening visit, participants will undergo a detailed medical history and physical examination and then will complete a mental test while lying down and standing. If eligible based on the results of the mental test, participants will undergo a pregnancy test if female and of childbearing potential, measurements of blood pressure and heart rate and blood draws while lying down and standing up, and a test to determine if they can tolerate being in a lower body negative pressure (LBNP) device that distributes more blood to the legs to mimic standing. If eligible based on the results of the screening visit, participants will be asked to complete an online questionnaire and two study visits that are separated by at least one week. At these study visits, they will perform a mental test in a magnetic resonance imaging (MRI) scanner. The LBNP device will also be used while in the MRI scanner to distribute more blood to the legs to mimic standing.
