Functional magnetic resonance imaging (fMRI) and psychophysical studies of sensory perception and cognition

The purpose of this study is (1) to understand how the brain processes sensory information and (2) how this is affected by factors like blindness or synesthesia. In addition to behavioral testing, the study will use functional magnetic resonance imaging (fMRI) which enables us to take pictures of the brain while you are doing a task, using an instrument called an MRI scanner.

Participants will perform simple behavioral tasks either stand-alone or while being scanned; they may also complete questionnaires or rating scales.

Development of Lighting Application Efficacy Measurement Framework

This study seeks to analyze how subjects perceive brightness in a space. For this purpose, two separate studies will be conducted in a real setting in the Lighting Lab. In one experiment, subjects will be asked to judge the brightness of a task surface under different lighting conditions, which will be generated automatically, by assigning a value to the brightness level. In the other experiment, subjects will be asked to compare various automatically generated lighting conditions in side-by-side bays and adjust the lighting using a dial knob in one of the bays to match the light level in the other one in each condition.

Evaluating the consequences of mistimed light-emitting device use on cardiac activity and sleep health

The study is being done to find out whether wearing blue light-blocking glasses in the evening improves subsequent sleep. This is a 21-day study where participants will be asked to wear a sleep-monitoring “actiwatch”, an activity monitor, and a heart tracker, as well as to provide screenshots of their smartphone’s screen time app for three weeks. Participants will also be given the option to wear a blood pressure cuff on their arm for three days during the second half of each week, for a total of nine days.

Study participants will be asked to wear small devices on their wrist, hip, and shirt collar, and provide screenshots of their smartphone screen time app for three weeks. During the second and third weeks, participants will be asked to wear a pair of blue light-blocking glasses. Halfway through each week, participants will also be asked to wear a blood pressure monitor for 3 days/nights.There will be a total of seven in-person visits. At the first visit we will explain the study, ask interested participants to sign a consent form, collect information, and distribute study materials and devices. During all subsequent visits, participants will answer questionnaires and be provided additional study materials and devices.

Defining the role of slow eye movements on limb motor control

The purpose of the study is to examine how slow eye movements called smooth-pursuit eye movements, contribute to hand-eye coordination. Participants will grasp a robotic manipulandum and using the manipulandum interact with virtual visual stimuli in an augmented-reality environment.

The role of middle temporal and frontoparietal areas in limb motor control

The goal of this research is to understand the role of motion-processing areas on limb motor control. We will be using behavioral studies and combining that with functional brain imaging, EEG, and non-invasive brain stimulation using transcranial magnetic stimulation (TMS). TMS has been used in thousands of studies and is a very safe method to understand brain function for eye hand coordination.

There will be three visits. Participants will under go brain scanning. They will perform eye-hand coordination tasks by grabbing a robotic manipulandum. During the eye-hand coordination tasks, participants' brain activity will be measured using electroencephalography (EEG) and muscle activity using surface electromyography (EMG). Researchers will also apply transcranial magnetic stimulation (TMS) to temporarily inhibit and excite different brain areas. TMS is a noninvasive procedure that uses magnetic fields to stimulate nerve cells

Characterizing the Visual Pathway in Epilepsy

This research is being done to determine whether the way your brain processes vision is involved in the epilepsy disease process. There has been recent evidence suggesting that epilepsy patients, compared to healthy controls, have thinner retinas, specifically a layer called the retinal nerve fiber layer, the inner most layer of the retina. This study will expand on that finding by investigating any differences in all of the retinal layers, as well as visual function, between epilepsy patients and healthy controls.

Investigating Face Processing Behavior and Neural Circuitry

The ability to recognize faces differs across people. We are studying this variability in behavior and in brain responses in young adults (ages 18-25 years) in the Lab of Developmental Neuroscience at Penn State. If eligible, you will do face recognition tasks on the computer and answer survey questions. You may also be asked to participate in another session in which we take pictures of your brain using MRI. Volunteers are paid $10/hr for time in the lab. Interested participants can start the screening processing by clicking on this confidential screening link here:https://pennstate.qualtrics.com/jfe/form/SV_9NPJ20bQAPd0VKZ

Remote testing for psychophysical studies of sensory perception and cognition

The purpose of this study is (1) to understand how the brain processes sensory information and (2) how this is affected by factors like blindness or synesthesia.

Participants will complete simple online tasks, for example judging differences in auditory pitch; processing visual and auditory stimuli in congruent and incongruent pairings; rating the sound-symbolic properties of either real words, pseudowords, or both; or discriminating between two stimuli on the basis of their structural properties over a change in their surface properties, and vice versa.
