Cognitive Neuroscience “Meet & Greet” “Emergence and evolution of a dynamic dissipative network.”
Cognitive Neuroscience “Meet & Greet” • Purpose • Link up researchers & clinicians within and across schools at CWRU (…+ other local institutions) • Inclusive (people can continue to sign up here: http://www.surveymonkey.com/s.aspx?sm=t_2flbgk21OsT1idofEvNcNg_3d_3d ) • First step, next steps: website, regular meetings, external speakers, retreat. (let us know) • Strategic Planning: what strengths are already here, where do we want to go? • Dept. Cognitive Science: Undergrad <3 yrs old, >70 majors. MA Cognitive Linguistics. Aims to links up CWRU strengths.

Effects of long term voluntary exercise on the Forced Swim Test in Rats Patrick Chirdon1,2, Pingfu Feng1, 1: Case Western Reserve University 2: Department of Medicine/Division of Pulmonary, Critical Care and Sleep Medicine, Department of Psychiatry, Case Western Reserve University 3: Louis Stokes Cleveland VA Medical Center
Background: It is a common understanding that exercise benefits human health in many aspects. For example: 1. Exercise improves mood. 2. Exercise combats chronic diseases. 3. Exercise helps manage body weight. 4. Exercise strengthens heart and lungs. 5. Exercise promotes better sleep. 6. Exercise can increase reproductive behavior. Objectives:To determine if long term voluntary exercise would benefit mood Design: Voluntary exercise 10 wks Swim test 15 min from age 25 days Ten wks later
Ten weeks of wheel activity • Conclusion: Exercise does have a natural antidepressant • Like effect on behavior, but exercise is only effective in • Increasing active behaviors if the rat is older than 6.5 • Weeks. Rats older than 6.5 weeks have motivation to exercise that younger rats have not developed.

FMRI Evaluation of Chemobrain What is Chemobrain ? • Overall reduction in cognitive performance: primarily in attention, concentration , information processing speed and memory • Self report and confirmed by neurobehavioral testing • Dramatic negative impact on QUALITY OF LIFE. Compromises daily functioning at home, job and socially Study Objective : • Develop fMRI methodology to identify neuronal substrate affected by chemotherapy • Same fMRI methodology can then be used to longitudinally evaluate efficacy of interventional therapies developed to address the chemotherapy induced cognitive deficits. FMRI Study : • Interrogate functional networks supporting working memory andattention Stroop Task N-back Task ( 1 and 2 back ) ****Similar Paradigms being used to evaluate Bariatric surgery patients pre and post surgery

Visual-Spatial-Motor Tasks in Brain Imaging Studies John A. Jesberger Case Center for Imaging Research
Video Games fMRI Tasks Visual Feedback & Direction Isolated from hands Head: not moving Body: not moving Hands executing complex tasks in a VR space on the screen He could easily be doing this in an MRI
Advantages of the Standard Video Game Platform for fMRI • Hundreds of millions of potential subjects already trained by Nintendo, Microsoft, & Sony • Games are more fun – better tolerance & engagement of subjects in more complex tasks • Tools and expertise for development now widespread • VR Labs and game design curricula at many universities • CWRU Virtual Worlds Laboratory • Leads to much faster development cycle • Controller and first task developed in 6 months!
Screen shot of our Block Design “Game” Design To Match First block picked up being rotated for placement Blocks MRI compatible controller Already Built and tested Control Scheme
First maps of neural activation while performing a Block Design Task Each epoch contained 44 sec Block Design (active) 44 sec Fixation (control) Repeated for 5 epochs Block design was self-paced, i.e. after completing a pattern the subject was presented a new pattern until 44 seconds was up. Total trial time 7:24 (min:sec)
