Maria-Ioanna Stefanou^1,2, David Baur^1,2, Paolo Belardinelli^1,2, Til Ole Bergmann^1,2, Corinna Blum^1,2, Pedro Caldana Gordon^1,2, Jaakko O. Nieminen^1,2,3, Brigitte Zrenner^1,2, Ulf Ziemann^1,2, Christoph Zrenner^1,2

¹Department of Neurology & Stroke, University of Tübingen, ²Hertie Institute for Clinical Brain Research, University of Tübingen, ³Department of Neuroscience and Biomedical Engineering, Aalto University

This paper describes real-time electroencephalography-triggered transcranial magnetic stimulation to study and modulate human brain networks.

Chemistry

DNA Origami-Mediated Substrate Nanopatterning of Inorganic Structures for Sensing Applications

Petteri Piskunen¹, Boxuan Shen¹, Sofia Julin¹, Heini Ijäs^1,2, J. Jussi Toppari³, Mauri A. Kostiainen^1,4, Veikko Linko^1,4

¹Biohybrid Materials, Department of Bioproducts and Biosystems, Aalto University, ²University of Jyväskylä, Nanoscience Center, Department of Biological and Environmental Science, University of Jyväskylä, ³University of Jyväskylä, Nanoscience Center, Department of Physics, University of Jyväskylä, ⁴HYBER Center of Excellence, Department of Applied Physics, Aalto University

Here, we describe a protocol to create discrete and accurate inorganic nanostructures on substrates using DNA origami shapes as guiding templates. The method is demonstrated by creating plasmonic gold bowtie-shaped antennas on a transparent substrate (sapphire).

Neuroscience

Post-Movie Subliminal Measurement (PMSM), for Investigating Implicit Social Bias

Mamdooh Afdile^1,3,5, Iiro P. Jääskeläinen^1,2,4

¹Department of Neuroscience and Biomedical Engineering, Aalto University, ²Advanced Magnetic Imaging (AMI) Centre, Aalto NeuroImaging, Aalto University, ³Department of Media, School of Arts Design and Architecture, Aalto University, ⁴International Laboratory for Social Neuroscience, Institute of Cognitive Neuroscience, National Research University Higher School of Economics, ⁵Department of Film and Media, Stockholm University of the Arts

This protocol describes the use of movies to investigate brain mechanisms underlying implicit social biases during functional magnetic resonance imaging. When the face of a protagonist is presented after a movie subliminally, it evokes an implicit response based on knowledge of the protagonist gained during the movie.
