Transformations in Human Visual Cortex - from Neural Input to Recognition

点击翻译按钮获取中文摘要

Human behaviour is dominated by the visual system. This project proposes to trace the M, P, K neural systems isolated through Red/Green, Blue/Yellow and luminance stimuli to investigate processing for percepts of and attention to colour, motion and form in neurotypical humans. Nonlinear magnetoencephalography (MEG) is intended to provide the temporal structure of the different neural streams that feed these percepts. MEG based population receptive field analysis from virtual electrodes, will provide information about cortical feedback. A new theory of perception is expected to emerge, incorporating connections with contextual and top-down cognitive processes, furthering basic understanding.
