Complex natural sounds, such as bird singing, people talking, or traffic noise, induce decodable fMRI activation patterns in early visual cortex of sighted blindfolded participants [1]. That is, receives non-visual and potentially predictive information from audition. However, it is unclear whether the transfer auditory to areas an epiphenomenon imagery or, alternatively, driven by mechanisms independent experience. Here, we show that can decode sounds activity "visual" congenitally blind...
Using fMRI decoding techniques we recently demonstrated that early visual cortex contains content-specific information from sounds in the absence of stimulation (Vetter, Smith & Muckli, Current Biology, 2014). Here studied whether emotional valence can be decoded during emotionally ambiguous stimulation. Participants viewed video clips which two point-light walkers interacted with each other, either neutrally (having a normal conversation) or negatively an argument). Videos were paired...
Abstract Event‐related potential studies using delayed match‐to‐sample tasks have demonstrated the presence of two components, N 270 and 400, possibly reflecting sequential processing multiple sources endogenous mismatch. To date, only investigated mismatch between a single cue target. In this study, we used distractor stimuli to investigate effect secondary source distinct from task‐relevant stimulus. Subjects performed paradigms in which target could match or one paradigm, task‐irrelevant...
This paper describes Applied Research Associates' (ARA) recent advances in Soldier augmented reality (AR) technology. Our AR technology, called ARC4, delivers heads-up situational awareness to the dismounted warfighter, enabling non-line-of-sight team coordination distributed operations. ARC4 combines compact head tracking sensors with advanced pose estimation algorithms, network management software, and an intuitive visualization interface overlay tactical iconic information accurately on...
Efficient processing of the visual environment necessitates integration incoming sensory evidence with concurrent contextual inputs and mnemonic content from our past experiences. To examine how this takes place in brain, we isolated different types feedback signals neural patterns non-stimulated areas early cortex humans (i.e., V1 V2). Using multivariate pattern analysis, showed that both time-distant information, coexist V2 as signals. In addition, found extent to which information is...
Natural images exhibit luminance variations aligned across a broad spectrum of spatial frequencies (SFs). It has been proposed that, at early stages processing, the coarse signals carried by low SF (LSF) visual input are sent rapidly from primary cortex (V1) to ventral, dorsal and frontal regions form representation input, which is later back V1 guide processing fine-grained high SFs (i.e., HSF). We used functional resonance imaging (fMRI) investigate role human in coarse-to-fine integration...
This paper describes performance evaluation of a wearable augmented reality system for natural outdoor environments. Applied Research Associates (ARA), as prime integrator on the DARPA ULTRA-Vis (Urban Leader Tactical, Response, Awareness, and Visualization) program, is developing soldier-worn to provide intuitive ‘heads-up’ visualization tactically-relevant geo-registered icons. Our combines novel pose estimation capability, helmet-mounted see-through display, processing unit accurately...
Abstract Identifying the objects embedded in natural scenes relies on recurrent processing between lower and higher visual areas. How is cortical feedback information related to organised areas? The spatial organisation of converging early cortex during object scene could be retinotopically specific as it coded V1, or centred areas, both. Here, we characterise scene-related V1. Participants identified foreground background images with occluded central peripheral subsections, allowing us...
Contextualization is a topic of utmost importance in the field missiology. Over past several years, missiological world has debated merits one particular approach to contextualization known as Insider Movement (IM). While much discussion focused on issues soteriology, hermeneutics, theology religions, and evangelism, this article intends assess potential for IM strategies produce biblically faithful churches. By leaning writings advocates recent publication Jan Prenger’s dissertation, Muslim...

When discriminating abstract objects isolated in peripheral visual field, object information can be detected non-stimulated foveal but not cortex (Williams et al., 2008). Conversely, complex natural scene (Smith & Muckli, 2010; Muckli al. 2015). This demonstrates cortical feedback contributions to and representation V1. Whether are automatically directed versus V1, or if this is due varying stimulus complexity/naturalism remains unknown. We addressed question using computer-generated images...
