Recently, the neuropeptides oxytocin and vasopressin have become of interest in the psychiatric literature as potential drug targets to treat some of these deficits in social cognition. Using data from a double-‐blind, within subject, fMRI drug study, we examined the effects of intranasally administered oxytocin and vasopressin on the neural response to social eye gaze cues in neurotypical controls. Eye gaze directionality serves as a probe for social attention, which is an important aspect of human social cognition. My responsibilities for this project included: Writing and editing MATLAB scripts for analysis of the behavioral and fMRI data Preprocessing the fMRI data using SPM8 and MATLAB scripts Performing first-‐ and second-‐level analyses on the fMRI data using SPM8 and MATLAB scripts • Extracting fMRI betas values from first-‐level general linear models and performing various behavioral and beta value analyses using SPSS • Reviewing the relevant literature • Interpreting the results from the group level behavioral and fMRI data analyses • Writing up the findings for publication as first author Project: Human Striatal Responses to Motivation vs. Reward Anticipation •

The deficits in motivation processing that are prominent in schizophrenia can be quite debilitating and make it difficult for individuals suffering from schizophrenia to function effectively in mainstream society. Unfortunately, the neurobiological basis of motivation is not well understood in neurotypical population which makes it difficult to find biologically-‐based treatments to address these motivational deficits in schizophrenic population. In an attempt to advance our understanding of neural circuitry involved motivation processing, this project utilized two novel variants of the Monetary Incentive Delay fMRI paradigm to determine the ventral striatum’s (a limbic structure which has a long association with reward-‐predicting cues) role in motivation, disentangled from reward processing (which is intact in schizophrenia).

Recent genetics literature has suggested that individuals with the maternal uniparental disomy subtype of Prader-‐Willi Syndrome display some genetic similarities with a small but significant percent of individuals diagnosed with idiopathic autism. This fact resulted in a large scale project evaluating autistic symptomology in patients with Prader-‐Willi Syndrome. An earlier part of this project established that populations with Prader-‐Willi Syndrome exhibited similar behavioral deficits in facial processing to those found in Autism Spectrum Disorder. The goal of this study was to extend those findings by determining whether individuals with Prader-‐Willi Syndrome display an atypical neural response to facial processing, similar to that found in Autism Spectrum Disorder. This was achieved by running individuals with Prader-‐Willi Syndrome, Autism Spectrum Disorder, and neurotypical controls through a commonly used fMRI face localizer paradigm contrasting blocks of face pictures with blocks of house pictures. My responsibilities for this project included: •
•
•
•
•
•
Reviewing the relevant literature Analyzing and interpreting the group level fMRI data using Brain Voyager, including within group contrasts, between group contrasts, and ANOVA interaction effects Extracting beta values from the fMRI data using Brain Voyager Analyzing and interpreting demographic data, various neuropsychological measures (e.g. SRS, Benton, and VABS), and beta values from the fMRI data using SPSS Drafting sections of the manuscript for publication as second author Drafting and presenting a poster at the 2013 Gatlinburg Conference on Research and Theory in Intellectual and Developmental Disabilities Miscellaneous Lab Responsibilities Apart from my work on the Facial Processing in Prader-‐Willi Syndrome project, I was also involved in: •

2010-‐2013 Training other lab members how to use Brain Voyager and SPSS Completing literature searches on various clinical populations of interest for the lab Undergraduate Research Assistant Department of Cognitive Science, Case Western Reserve University; Cleveland, Ohio Brain Mind and Consciousness Lab Principle Investigator: Anthony Jack, Ph.D. Project: Meta-‐Analysis and Functional Annotation The function of the default mode network and its relationship with the task-‐positive network has recently been of particular interest in the neuroimaging literature, for both clinical populations and cognitive neuroscience in general. One of the more recent theories suggests that the default mode network is responsible for social and emotional processing, and that it displays an antagonistic relationship with the task positive network which is primarily involved in processes related to reasoning about the physical world/environment. The goal of this project was to use data from previous fMRI studies of various processes previously associated with the default mode network to evaluate this theory and see how it compares to other theories about the default mode network. This was completed by performing various Activation Likelihood Estimation (ALE) based meta-‐analyses on data taken from 299 fMRI papers examining various social, emotional, Tillem CV page 4 Revised 04/2015
