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.
