“…The visual response latency of V4 neurons differed between the SFM and SFL conditions. Delay to represent a shape signal in the V4 was longer in the SFL condition (177 ms) than in the SFM condition (123 ms) (Handa et al., ) (Figure ). These results suggest that the V4 encodes a specific shape and/or constituent parts of shape regardless of cues, but that the underlying process for the extraction of shape and/or its constituent part is dependent on cues (motion vs. luminance).…”

“…Approximately 50%–60% of shape‐selective V4 neurons for SFM revealed a similar shape preference to the SFL, suggesting cue‐invariant shape selectivity. However, the temporal properties of shape‐modulated neural activity differed between the two cues (Handa, Unno, & Mikami, ; Handa et al., ; Mysore et al., , ). The visual response latency of V4 neurons differed between the SFM and SFL conditions.…”

Human and non-human primates can readily perceive the shape of objects using visual motion. Classically, shape, and motion are considered to be separately processed via ventral and dorsal cortical pathways, respectively. However, many lines of anatomical and physiological evidence have indicated that these two pathways are likely to be interconnected at some stage. For motion-defined shape perception, these two pathways should interact with each other because the ventral pathway must utilize motion, which the dorsal pathway processes, to extract shape signal. However, it is unknown how interactions between cortical pathways are involved in neural mechanisms underlying motion-defined shape perception. We review evidence from psychophysical, lesion, neuroimaging and physiological research on motion-defined shape perception and then discuss the effects of behavioral demands on neural activity in ventral and dorsal cortical areas. Further, we discuss functions of two candidate sets of levels: early and higher-order cortical areas. The extrastriate area V4 and middle temporal (MT) area, which are reciprocally connected, at the early level are plausible areas for extracting the shape and/or constituent parts of shape from motion cues because neural dynamics are different from those during luminance-defined shape perception. On the other hand, among other higher-order visual areas, the anterior superior temporal sulcus likely contributes to the processing of cue-invariant shape recognition rather than cue-dependent shape processing. We suggest that sharing information about motion and shape between the early visual areas in the dorsal and ventral pathways is dependent on visual cues and behavioral requirements, indicating the interplay between the pathways.

Neuroscience, especially visual neuroscience, is a burgeoning field that has greatly shaped the format and efficacy of education. Moreover, findings from visual neuroscience are an ongoing source of great progress in pedagogy. In this mini‐review, I review existing evidence and areas of active research to describe the fundamental questions and general applications for visual neuroscience as it applies to education. First, I categorize the research questions and future directions for the role of visual neuroscience in education. Second, I juxtapose opposing views on the roles of neuroscience in education and reveal the “neuromyths” propagated under the guise of educational neuroscience. Third, I summarize the policies and practices applied in different countries and for different age ranges. Fourth, I address and discuss the merits of visual neuroscience in art education and of visual perception theories (e.g., those concerned with perceptual organization with respect to space and time) in reading education. I consider how vision‐deprived students could benefit from current knowledge of brain plasticity and visual rehabilitation methods involving compensation from other sensory systems. I also consider the potential educational value of instructional methods based on statistical learning in the visual domain. Finally, I outline the accepted translational framework for applying findings from educational neuroscience to pedagogical theory.

Frontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation.
