A multisensory evoked potential brain-computer interface for communication in ALS
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 Ecology of Infant Emotion-Regulation
This study aims to understand how emotion regulation in infants develops within the context of family and community support. We're particularly interested in the relation between mother-infant synchrony, facilitated by family and community support, and infant emotion regulation. We will use a multi-method approach to collect simultaneous brain activation in mothers and infants, infant's physiological responses, and information about family and community support.
Participants complete an online survey, then come in for 1 in-person visit. This research aims to find out how patterns of brain activation in infants and mothers and infant physiological responses relate to the real life, face-to-face interactions that mothers and babies usually engage in.

Parent-to-child anxiety transmission in early childhood: Capturing in-the-moment mechanisms through emotion modeling and biological synchrony
Anxiety can emerge as early as pre-school age (4-7) and is often linked to anxiety in the parent. This study will examine patterns of brain and behavioral synchrony in parent-child pairs as they complete puzzles together and other social activities.
Participation requires three steps; a remote video session with the primary parent, an in-lab visit scheduled with the primary parent and child, and then an additional set of questionnaires given to the secondary caregiver.The remote session consists of obtaining consent, 2 questionnaires, and a clinical interview. The in-lab visit typically lasts about 2-3 hours, consisting of two parent-child activities and several child-only activities. Participants will be asked to wear mobile eye-tracking glasses and special caps used to measures brain activity during some of the tasks.

The Role of Parental Emotion Regulation in Parent-Child Conflicts
This study seeks to examine parenting skills in responses to child misbehavior. Parents complete rating scales about their child's symptoms and behaviors and also participate in computer tasks to measure brain wave activity through EEG. There is an optional section where parent and child will be video recorded while completing activities together. Following the testing sessions are 8 weeks of counseling sessions for parents to help better manage their child's attention and behavior symptoms.
Participants will complete C-DISC while caregiver will complete rating scales around ADHD, ODD, and CD symptoms during initial visit. On the second visit, participants will complete emotion regulation tasks while EEG data is collected. Caregivers will also complete a monetary task while connected to EEG equipment. Parents will use LifeData to report inattentiveness, hyperactivity, and oppositional behaviors over 14 days. Optional parent child interaction and 8-week parenting intervention are offered to participating families.

Linking brain network dynamics to smoking-related behavior
Most attempts to quit smoking end in relapse, or a return to regular smoking. One of the biggest threats to cessation is a lapse (i.e., any cigarette use during a quit attempt). Thus, characterizing why lapses occur is essential to understanding and preventing smoking relapse. Functional magnetic resonance imaging (fMRI) is a promising method for characterizing the psychological processes that lead to smoking lapses because it provides a way to measures patterns of brain activity thought to reflect relevant mental processes as they change over time. However, methodological issues have hindered the ability to capitalize on this potential and prevented an understanding of how brain activity and corresponding psychological processes unfold in the critical moments that immediately precede a smoking lapse. The proposed project will address this knowledge gap using a novel fMRI paradigm adapted from a well-validated behavioral lapse task. The goals of the project are to characterize changes in brain activity that lead up to a lapse and to investigate how these changes are related to concurrent affect and subsequent cigarette use.
There will be two in-person visits, both will involve completion of computerized questionnaires and one will involve completing and MRI scan

Pain and the Brain in Different Virtual Reality Environments
Research has shown that exposure to different environments alters perceived pain intensity. To explore whether pain differs in various VR environments, we are going to use virtual reality to immerse participants in different settings. At the end of every immersion, we are going to induce controlled experimental thermal pain to participants (like holding a hot cup of coffee) to understand whether their pain differs. We are also going to measure their stress, affect and brain activity using behavioral, electrophysiological (skin conductance and heart rate) and functional Near-Infrared Spectroscopy (fNIRS) methodology. The results have the potential to improve pain treatment in medical settings, where virtual reality is regularly used as a non-pharmacological analgesic, but also to inform architectural design and urban planning, so our cities and homes promote improved pain outcomes.
There will be one in-person visit that will last ~3.5 hours. During the visit you will be immersed in Virtual Reality environments, you will experience painful (but tolerable) heat stimulations, like holding a hot cup of coffee, and you will be asked to rate your pain intensity. We will record your brain activity using functional Near Infrared Spectroscopy (fNIRS) as well as your palm sweatiness and pulse. You will be compensated $25 per hour for your time.

Pilot evaluation of a multisensory evoked potential brain-computer interface
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.

A randomized, open-label, multicentric, two-arm pivotal trial of SonoCloud-9 combined with carboplatin (CBDCA) vs standard of care lomustine (CCNU) or temozolomide (TMZ) in patients undergoing planned resection for first recurrence glioblastoma
We are asking you to take part in this voluntary research study because you have a brain tumor (glioblastoma) that has gotten worse despite first treatment.The purpose of this voluntary research study is to is to learn if the SonoCloud-9 (SC9) implantable device can be used in combination with Carboplatin chemotherapy to help control glioblastoma at recurrence. Neither Sonocloud-9 (SC9) in combination with Carboplatin chemotherapy is not FDA approved.
As part of your routine care, you will be asked to undergo surgery to remove the tumor that has come back. You will be randomized into one of the treatment groups. If you are in the study drug group the surgeon will insert the SonoCloud-9 device (SC9) implant into the skull bone at the end of the tumor resection surgery. If you are in the routine treatment group, the surgeon will close the wound without implanting the SC9 device.The treatment itself will start within 12 to 21 days after the randomization.-If you are in the study drug group you will receive up to 7 doses (every 3 weeks) of Carboplatin at the same time the SonoCloud-9 device is being activated. Further details on the procedures are described below. A brain MRI (Magnetic Resonance Imaging) scan will be performed after the first cycle as part of the research to evaluate opening of the BBB (blood-brain barrier). -If you are in the routine treatment group, you will receive up to 4 doses of Lomustine (every 6 weeks), or, if considered as best appropriate, up to 6 doses of Temozolomide (every 4 weeks). Additional in-person hospital visits or telehealth consultations by video or phone will be performed at regular intervals.

Neural Correlates of Cognitive Dysfunction in Postural Tachycardia Syndrome
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.
