Advanced Intelligent Systems, EarlyView.Inspired by the eye movements of humans, a multi‐degree‐of‐freedom (multi‐DOF) miniature piezoelectric actuator with a square‐circular ring structure is proposed. The actuator demonstrates a well‐balanced performance in miniaturization, operational efficiency, actuation precision, and load‐driving capability.

Many visual disorders produce acquired color vision defects. Color vision theory emphasizes several stages of visual processing: prereceptoral filters (lens, macular pigment, pupil), cone photopigments (L-, M-, and S-cones), and postreceptoral processes (red-green, S-cone, and luminance channels).

Cell Biophysics, 1986 Two main topics will thread their way through this paper: The structure of the monkey striate cortex, including its inputs and outputs, and the physiological basis of color vision. When Margaret Livingstone and I began this work four years ago we did not set out to study color, but the structures in the cortex that we have been looking at turn out to ...
