Purely optical tomography : atlas-based reconstruction of brain activation
… here. A purely optical tomography of the brain during neural activity will greatly enhance DOT applicability and provide many advantages, in the sense that DOT low cost, portability and non-invasiveness would be fully exploited without the compromises due to the MRI role in the DOT forward …

Brain Activation and Connectivity In Non-Disabled Multiple Sclerosis Patients
… and diffusion tensor imaging (DTI) to elucidate brain mechanisms associated with lack of clinical disability in patients with MS. Recent evidence has implicated cortical reorganization as a mechanism to limit the clinical manifestation of the disease. Functional MRI was used to test the …

An implantable piezoelectric ultrasound stimulator (ImPULS) for selective deep brain activation
… current neural interfaces targeting the deep brain face significant limitations in spatial resolution and potency due to tissue attenuation. We developed an implantable piezoelectric ultrasound stimulator (ImPULS) that generates an ultrasonic focal point pressure of 100 kPa and can …

Exposure-response prevention, executive function, and brain activation in participants with Obsessive-Compulsive Disorder
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2024-08-01

Brain activation following constraint-induced movement therapy using functional near infrared spectroscopy in stroke patients
… that CIMT influences the reorganization of the brain (Levy, Nicholas, Schmalbrock, Keller, & Chakeres, 2001). Functional Near-Infrared Spectroscopy (fNIRS) is an novel method of mapping the brain by using light to measure changes in oxygenated and de-oxygenated hemoglobin concentration in …

The Effect of Marijuana Craving on Brain Activation and Recognition Memory in Healthy and Bipolar Adolescents
… (HA). The four groups were compared on tests of brain activation in response to a cue-reactivity task, self-reported craving and performance on a recognition memory task in order to parse the cognitive effects of bipolar disorder and the alteration in cognitive performance related to the effects …

Effects of Social and Non-Social Interpretations of Complex Images on Human Eye Movement and Brain Activation
… the behavior of other people. The eyes and brain must work together to fixate and process only the most critical social signals within a scene while passing over and / or completely ignoring other aspects of the scene. While brain activation to isolated presentations of objects and people …

Effects of Atomoxetine and Methylphenidate on functional brain activation in Medication-naive children with Attention Deficit Hyperactivity Disorder
… and the non-stimulant Atomoxetine (ATX) in ADHD. Brain activation and task performance during motor inhibition (Stop), time discrimination (TD) and working memory (WM) tasks were compared in 20 medication-naive ADHD boys (10-17 years-old) after a single dose of MPH (0.3mg/kg), ATX (Img/kg) or …

Maternal HPA Axis Function During Parenting is Associated with Reduced Brain Activation to Infant Cry and More Intrusive Parenting Behavior
… that maternal cortisol function and maternal brain response to infant stimuli are separately related to differences in parenting behavior. Evidence from animal models have demonstrated that chronically high cortisol concentration alters brain structure and function, suggesting that studying …

A biopsychosocial approach to investigating appetite self-regulation in children: The role of temperament in developmental trajectories, parent-child interactions, and brain activation
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-08-01

Behavioral and neurological investigations into pathological gambling as a behavioral addiction
… and substance addictions, limbic and cortical brain systems are activated during gambling related tasks and activities. However, as gambling pathology increases, brain activation in these regions have been reported to decrease, and it is unclear how pathological gamblers brain activation …

Exploring the fathering brain: insights from neural activation
… A variety of studies have focused on how the brain changes at the beginning or end of the breeding season (Gozdowska et al., 2006; Hairston et al., 2003; Meitzen et al., 2009; Nakao et al., 2008; Paul et al., 2009), but less is known about how the brain, mediates behavioral plasticity during …

Investigating the Effects of Custom Made Orthotics on Brain Forms: A Pilot Study
… this novel approach and technique of recording brain activity, wirelessly and continuously, during human gait, and (2) if custom made orthotics will alter the brain activity patterns recorded. METHODS: Gait trials were performed on 16 participants walking with and without orthotic devices in …

Spatial alignment of functional regions in fMRI
… step for discovering a common structure in brain activation regions from multi-subject fMRI data is the ability to find spatial correspondences across subjects. This has proven to be a challenging problem due to the lack of a ground truth and variability in anatomical brain structure, …

The use of free tryptophan and prolactin as peripheral indices of brain serotoninergic activity
… may lead to an increased rate of synthesis of brain serotonin (5-HT). This may impair central nervous system function and cause increased perceptions of fatigue and deteriorate exercise performance. Two-fold increases in plasma concentrations of f-Trp have resulted in a 20% and 53% increase in …

Additive and Interactive Effects of Comorbidity During Emotion Processing
… anxious arousal, and anhedonic depression on brain activation as measured by fMRI while individuals performed an emotion-word Stroop task. As predicted, brain activation distinguished anxious groups in a left inferior frontal region associated with speech production and in a right-hemisphere …

fMRI detection with spatial regularization
… non-invasive imaging technique used to study the brain. Neuroscientists have developed various algorithms to determine which voxels of the images are active. Most of these algorithms, operating on the signal of each voxel separately, are referred to as the voxel-by-voxel detectors. Among those …
