Lexical Decision Task for Studying Written Word Recognition in Adults with and without Dementia or Mild Cognitive Impairment Alexandre Nikolaev1, Eve Higby2,3, JungMoon Hyun4, Sameer Ashaie5,6 1Helsinki Collegium for Advanced Studies, University of Helsinki, 2University of California, Riverside, 3California State University, East Bay, 4Hunter College, City University of New York, 5Feinberg School of Medicine, Northwestern University, 6Shirley Ryan AbitilyLab This article describes how to implement a simple lexical decision experiment to assess written word recognition in neurologically healthy participants and in individuals with dementia and cognitive decline. We also provide a detailed description of reaction time analysis using principal components analysis (PCA) and mixed-effects modeling.
An Aptamer-based Sensor for Unchelated Gadolinium(III) Osafanmwen Edogun1, Tracy Y. Chan1, Nghia H. Nguyen1, Anthony Luu1, Marlin Halim1 1Department of Chemistry and Biochemistry, California State University, East Bay The use of polydeoxynucleotide (44-mer aptamer) molecules for sensing unchelated gadolinium(III) ion in an aqueous solution is described. The presence of the ion is detected via an increase in the fluorescence emission of the sensor.
SSVEP-based Experimental Procedure for Brain-Robot Interaction with Humanoid Robots Jing Zhao1, Wei Li1,2, Xiaoqian Mao1, Mengfan Li1 1School of Electrical Engineering and Automation, Tianjin University, 2Department of Computer & Electrical Engineering and Computer Science, California State University The overall goal of this method is to establish an SSVEP-based experimental procedure by integrating multiple software programs to enable the study of brain-robot interaction with humanoid robots, which is prospective in assisting the sick and elderly as well as performing unsanitary or dangerous jobs.
