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.

人类的行为是由视觉系统控制的。该项目提议追踪通过红/绿色、蓝/黄和亮度刺激隔离的M、P、K神经系统，以研究神经典型人类对颜色、运动和形状的感知和注意力的处理。非线性脑磁图（MEG）的目的是提供不同的神经流，这些感知饲料的时间结构。从虚拟电极的基于MEG的群体感受野分析将提供关于皮层反馈的信息。一种新的感知理论有望出现，它将与上下文和自上而下的认知过程相结合，促进基本的理解。
