Contributions From the Analysis of Graphs for Identification of Neural Cliques

The aim of the study is to demonstrate that our semantic knowledge (elements of our long-term memory and the process we use them) respond to a graphic organisation and gather together following accurate patterns called cliques (neural networks).

Computerized Intervention Targeting Cognitive Control Deficits in Depressed Adults

Project:EVO is a video-game based intervention that targets neural networks associated with cognitive control. The same networks have been implicated in poor treatment response in middle and older aged adults suffering from major depression. Related work has demonstrated that healthy older adults show significant improvement in cognitive control. In a very small sample of older adults suffering from depression (n=12), we found similar improvements in selective attention and wor...

Resting-State Neural Connectivity in Patients With Subjective Tinnitus Without Bother

Tinnitus is the occurrence of an auditory sensation without the presence of an acoustic stimulus. Approximately, 50 million people in the United States experience chronic tinnitus and 15 million of these people have bothersome tinnitus. Several studies have shown that people who are bothered by their tinnitus have difficulty in concentration and focus. Through imaging modalities we have deranged neural networks responsible for attention. Only 20 percent of patients diagnosed wi...

Neural Mechanisms Underlying the Antidepressant Effects of Sleep Deprivation

From 40 to 60% of patients with depression experience a rapid and significant improvement of mood with one night of sleep deprivation (SD). The neural mechanisms underlying this effect have not been elucidated. Recent advances in functional neuroimaging have provided new opportunities to investigate state changes in regional brain function, along with a better understanding of the neural networks affected by depression and SD. Here we propose to study a group of N=48 antidepres...

Neural Correlates of Repeated tDCS

Healthy ageing and pathological ageing in the context of a neurodegenerative disease are both associated with changes in brain network integrity. Episodic memory is especially affected in Alzheimer's disease, but is also decreased in healthy ageing. Consequently, the memory-relevant brain networks are especially altered. Transcranial direct current stimulation (tDCS) has previously been implemented in different clinical- and non-clinical settings and has shown to beneficially i...

Neural Indices Associated With Relapse in Cannabis Dependence

The aim of this fMRI study is to investigate neural indices of relapse in cannabis dependence. The development and maintenance of drug addictions have been associated with deficits in cognitive control, craving and impaired stress regulation. Therefore, neural markers of brain processes underlying the beforementioned components will be studied. Subsequent follow-up drug use interviews will reveal associations between relapse in cannabis dependence and alterations in brain netwo...

Characterizing the Neural Bases of Motivational Disorders After Stroke

The aim of the study is to quantify elementary mechanisms of motivation, with innovative tools adapted to clinical settings, in healthy subjects, and in stroke patients, and to investigate their predictive value related to morbimortality, disability, and dependence. The secondary aim of the study is to investigate the neural substrates of motivational mechanisms, and to study the impact of lesions in the grey and the white matter, the influence of lesion site, and the consequen...

Food Reward Processing in the Human Brain

The aim of this study is to investigate the influence of different metabolic states and hormonal satiety signalling on responses in neural reward networks.

Social Networks and Renal Education: Promoting Transplantation

There are significant and persistent disparities in access to kidney transplantation and as a result most patients with end stage renal disease receive hemodialysis (HD). HD is unique as it is a treatment performed in a group setting which lends itself to forming social networks. The goal of this research study is to identify and characterize the social networks of HD patients and measure the influence of HD social networks on knowledge, attitudes, and behaviors towards transpl...

Neural Enabled Prosthesis for Upper Limb Amputees

This study is designed to evaluate the feasibility of The Adaptive Neural Systems Neural-Enabled Prosthetic Hand (ANS-NEPH) system.

Brain-Based Biomarkers in Response to TMS in MDD

The overarching goal of this research program is to elucidate causal and directional neural network- level abnormalities in depression, and how they are modulated by an individually-tailored, circuit-directed intervention. By using concurrent TMS and EEG, the investigators can overcome a major limitation of EEG - the inability to demonstrate causality. Here, we plan to recruit patients with medication-resistant depression undergoing rTMS treatment. At multiple time points, we w...

The Comparison of Effectiveness of CBT and rTMS on Anhedonia and Rumination in Patients With MDD

This study aims to compare the effectiveness of rTMS, classical cognitive-behavioral therapy and religious cognitive-behavioral therapy on the reduction of Anhedonia and rumination and their associated neural networks. In a randomized double-blind trial, 60 patients with major depressive disorder (MDD) in Atieh Clinical Neuroscience Center are assigned to four groups. The first group receives bilateral rTMS for 10 sessions on DLPFC; the second group receives sham rTMS for 10 se...

Functional MRI Study in Children With a Developmental Coordination Disorder (DCD) and/or Developmental Dyslexia (DD)

All the studies underlined the high frequency of co-morbid associations in specific learning disorders. Understanding the reasons for these associations could enable us to determine the cerebral bases that underlie each disorder. Their frequent association suggests the etiological bases are partly common, it seems logical to turn to explanatory models of various common specific disorders. The model recently proposed by Nicholson & Fawcett (2007) suggests a specific disorder of ...

The Role of Oxytocin in the Perception of Faces

The main objective of this project is to study whether intranasal oxytocin (OT) affects how young adults perceive and attend to infant and adult faces. Based on existing research the investigators predict that oxytocin will facilitate the allocation of attentional resources on infant faces (compared to adult faces). The investigators also predict that oxytocin will enhance the activity of reward neural-networks associated with the perception of infant faces. The behavioral effe...

Cannabinoids, Neural Synchrony, and Information Processing

The study examines the effects of delta-9-tetrahydrocannabinol (Δ9-THC), the principal active ingredient of cannabis, on neural synchrony. Neural synchrony is studied using electroencephalography (EEG).

HARP-Project 1 Cognitive Training

Emerging evidence from social neuroscience suggests that prefrontal cortex (PFC), insular and anterior cingulate cortex (ACC) regulate social and emotional responses to acute threats to social connectedness among young adults. Deficient neural reserve or overused neural compensation resulting from neurodegeneration is commonly observed in these frontal regions in old age. This aging-related "neural depletion" may have implications for how older adults respond to social threats,...

Impulsivity, Neural Deficits and Cocaine Addiction

The purpose of this study is to assess neurocognitive and associated neural regions/circuitry disruptions relevant to impulsive relapse in cocaine-addicted subjects, and the relationship of the cognitive and neural mechanisms of impulsivity/decision-making to relapse style.

Consolidation of Motor Learning of Writing Skills and Its Related Brain Activity Changes in Parkinson&Apos;s Disease

The basal ganglia play an important role in motor learning, especially during the consolidation phase of motor learning. This raises the question whether it is possible to sustain learning increments in a neurodegenerative condition such as Parkinson's disease (PD). The aim of this study is to gain knowledge on whether it is possible to relearn skills which are actually affected by PD, such as writing, and determine whether neuroplasticity is possible. In this randomized contro...

Deep Brain Stimulation (DBS) for Depression Using Directional Current Steering and Individualized Network Targeting

The goal of the study is to address the unmet need of TRD patients by identifying brain networks critical for treating depression and to use next generation precision DBS with steering capability to engage these targeted networks. The study's goal will be achieved through 3 specific aims: 1. Demonstrate device capability to selectively and predictably engage distinct brain networks 2. Delineate depression-relevant networks and demonstrate behavioral changes wit...

Depression, Adversity, and Stress Hormones (DASH) Study

The stress-related hormone cortisol has been studied in depression for decades. However, relatively little is known about the role of cortisol in psychological features of depression. Basic research shows that cortisol modulates brain processes that are highly relevant to depression (especially the neural substrates of negative biases in learning and memory formation). However, very few studies have directly examined the effects of cortisol on neural circuitry of learning in de...

Investigating the Cognitive Processes That Underlie Social Knowledge and Behavior

The purpose of the protocol is to localize the neural regions and systems mediating the forms of knowledge representations hypothesized by the principal investigator to be stored in the human prefrontal cortex. Utilizing a variety of experimental neuropsychological tasks during functional MRI, we will investigate hypotheses regarding the role of the dorsolateral and ventromedial prefrontal cortex in social cognition and emotional processing. We will ascertain the relationship b...
