What is the most efficient algorithm for converting human brain activity into a picture one’s visual experience? We are developing methods for decoding information about subjective visual experience from multiple stages of the visual system. For technical details see the many decoding methods presented in our recent papers (Kay et al., 2008; Naselaris et al., 2009; Nishimoto et al., 2011; Naselaris et al., 2012; Stansbury et al., 2013).
