Edge-like and line-like features result from spatial phase congruence, the local phase agreement between harmonic components of a spatial waveform. Psychophysical observations and models of early visual processing suggest that human visual feature detectors are specialized for edge-like and line-like phase congruence. To test whether primary visual cortex (V1) neurons account for such specifici...

Welcher Weg (which-path) detectors where complementarity is enforced without altering the interfering beams are analysed in terms of the quantum relative phase. In such a case, the measurement disturbs the interference via random classical phase shifts. This applies when the interfering particles are atoms or photons. In the case of photons, the quantum relative phase coincides with the field p...

The production and perception of coordinated rhythmic movement are very specifically structured. For production and perception, 0 degree mean relative phase is stable, 180 degrees is less stable, and no other state is stable without training. It has been hypothesized that perceptual stability characteristics underpin the movement stability characteristics, which has led to the development of a ...
