This article demonstrates an experimental design in which whole-body animated characters are used in conjunction with functional magnetic resonance imaging (fMRI) to investigate the neural correlates of observing virtual social interactions.

Neuroscience

Brain Imaging Investigation of the Neural Correlates of Emotional Autobiographical Recollection

Ekaterina Denkova¹, Trisha Chakrabarty¹, Sanda Dolcos^1,2, Florin Dolcos^1,2,3,4

¹Department of Psychiatry, University of Alberta, Edmonton, ²Psychology Department, University of Illinois, Urbana-Champaign, ³Neuroscience Program, University of Illinois, Urbana-Champaign, ⁴Beckman Institute for Advanced Science & Technology, University of Illinois, Urbana-Champaign

We present a protocol that allows investigation of the neural correlates of recollecting emotional autobiographical memories, using functional magnetic resonance imaging. This protocol can be used with both healthy and clinical participants.

Neuroscience

Brain Imaging Investigation of the Neural Correlates of Emotion Regulation

Sanda Dolcos¹, Keen Sung², Ekaterina Denkova³, Roger A. Dixon^4,5, Florin Dolcos^1,6,7

¹Department of Psychology, University of Illinois, Urbana-Champaign, ²Department of Computing Science, University of Alberta, Edmonton, ³Department of Psychiatry, University of Alberta, Edmonton, ⁴Department of Psychology, University of Alberta, Edmonton, ⁵Centre for Neuroscience, University of Alberta, Edmonton, ⁶Neuroscience Program, University of Illinois, Urbana-Champaign, ⁷Beckman Institute, University of Illinois, Urbana-Champaign

We present a protocol that allows investigation of the neural correlates of deliberate and automatic emotion regulation, using functional magnetic resonance imaging. This protocol can be used in healthy participants, both young and older, as well as in clinical patients.

Neuroscience

Brain Imaging Investigation of the Memory-Enhancing Effect of Emotion

Andrea Shafer¹, Alexandru Iordan², Roberto Cabeza³, Florin Dolcos^1,4

¹Centre for Neuroscience, University of Alberta, ²Neuroscience Program, University of Illinois, Urbana-Champaign, ³Center for Cognitive Neuroscience, Duke University, ⁴Psychology Department, Neuroscience Program, & Beckman Institute, University of Illinois, Urbana-Champaign

We present a protocol that uses functional magnetic resonance imaging to investigate the neural correlates of the memory-enhancing effect of emotion. This protocol allows identification of brain activity specifically linked to memory-related processing, contrary to more general perceptual processing, and can be used with healthy and clinical populations.

Neuroscience

Brain Imaging Investigation of the Impairing Effect of Emotion on Cognition

We present a protocol that allows investigation of the neural mechanisms mediating the detrimental impact of emotion on cognition, using functional magnetic resonance imaging. This protocol can be used with both healthy and clinical participants.

Biology

Two Types of Assays for Detecting Frog Sperm Chemoattraction

Lindsey A. Burnett¹, Nathan Tholl², Douglas E. Chandler²

¹Department of Animal Sciences, University of Illinois, Urbana-Champaign, ²School of Life Sciences, Arizona State University

Eggs and the extracellular coatings around eggs frequently release peptides, proteins and small molecules that communicate with sperm to guide them to the egg thereby promoting fertilization. Using frog sperm we describe and compare two classes of assays used to detect sperm chemoattraction – sperm accumulation assays and sperm tracking assays.

Neuroscience

A Comprehensive Protocol for Manual Segmentation of the Medial Temporal Lobe Structures

Matthew Moore^*1, Yifan Hu^*1, Sarah Woo¹, Dylan O'Hearn¹, Alexandru D. Iordan^2,3, Sanda Dolcos¹, Florin Dolcos^1,2,3

¹Psychology Department, University of Illinois Urbana-Champaign, ²Neuroscience Program, University of Illinois Urbana-Champaign, ³Beckman Institute for Advanced Science and Technology, University of Illinois Urbana-Champaign

The present work provides a comprehensive set of guidelines for manually tracing the medial temporal lobe (MTL) structures. This protocol can be applied to research involving structural and/or combined structural-functional magnetic resonance imaging (MRI) investigations of the MTL, in both healthy and clinical groups.

Medicine

Systems Biology of Metabolic Regulation by Estrogen Receptor Signaling in Breast Cancer

Yiru Chen Zhao¹, Zeynep Madak Erdogan¹

¹Department of Food Sciences and Human Nutrition, University of Illinois, Urbana-Champaign

Integration of data from genome-wide sequencing experiments and metabolomics experiments is a challenge. In this paper we report, for the first time, generation, analysis and integration of transcriptome, cistrome and metabolome data from breast cancer cells treated with estradiol.

Biochemistry

Single-Molecule Diffusion and Assembly on Polymer-Crowded Lipid Membranes

Satyaghosh Maurya¹, Vishwesh Haricharan Rai¹, Aditya Upasani¹, Saurabh Umrao^1,2, Diksha Parwana¹, Rahul Roy^1,3

¹Department of Chemical Engineering, Indian Institute of Science, ²Holonyak Micro & Nanotechnology Lab, University of Illinois, Urbana-Champaign, ³Center for BioSystems Science and Engineering, Indian Institute of Science

Here, a protocol to perform and analyze the binding, mobility, and assembly of single molecules on artificial crowded lipid membranes using single-molecule total internal reflection fluorescence (smTIRF) microscopy is presented.
