“…Also of interest for inhomogeneous tissue optics are speckle-optic methods and speckleinterferometry [230,231]. Useful information about coherent techniques and their applications to cell and tissue optics can be found in a few excellent reviews [196,232]. Ref.…”

Tissue optics is a rapidly expanding field of great interest to those involved in the development of optical medical technologies. In the present review both strongly (multiple) scattering tissues, such as skin, brain tissues, and vessel walls, and weakly scattering high-transparent tissues, such as eye tissues (cornea and lens), are discussed. For the former, radiation transport theory or Monte Carlo simulation are used to describe the propagation of light (laser beams). For weakly scattering ordered tissues, ensembles of close-packed Rayleigh or Mie scatterers are employed. Methods for solving the inverse problem of finding biotissue optical parameters are discussed. The propagation of photon-density diffusion waves in scattering and absorbing media is analyzed and the prospects of these waves for optical tomography are discussed. Polarization phenomena in both strongly and weakly scattering biotissues are discussed.

“…The low-frequency modulation of the velocity oscillation is well seen. This modulation is a consequence of the distributed and self-oscillating nature of Physarum contraction activity [9]. In Figure 6 several flow velocity profiles measured at different time instances corresponding to t 1 , .…”

“…The dynamics of the wall contraction and the cytoplasm shuttle flow in Physarum have been studied by numerous researchers implementing phase-contrast microscopy [8], laser Doppler microscopy [9,10] and image analysis [11] aiming, in particular, to assess the mechanism of synchronization of the oscillations and the nature of the pacemaker and synchrofactor. Mathematical models have been designed to describe complex dynamic phenomena [9,12].…”

The Doppler optical coherence tomography technique was applied to image the oscillatory dynamics of protoplasm in the strands of the plasmodium of slime mould Physarum polycephalum. Radial contractions of the gel‐like walls of the strands and the velocity distributions in the sol‐like endoplasm streaming along the plasmodial strands are imaged. The motility inhibitor effect of carbon dioxide on the cytoplasm shuttle flow and strand‐wall contraction is shown. The optical attenuation coefficient of cytoplasm is estimated.

“…These studies set the adhesion-dependence of the three-step migration model (see Sect. 2.3) on a solid mathematical basis, while the nonlinear dynamics of actin polymerization led to several models of cell migration based on symmetry breaking in the system [130,131]. However, there exist even more sophisticated models that combine the basic concepts to explain observations on cell mechanics [132].…”
