Estimation of self-motion by optic flow processing in single interneurons

Article Abstract:

Self-motion leads to the generation of optic flow fields in the eyes, based on the type and direction of the rotatory or the translatory locomotion. The visual interneurons extract the rotatory components from the optic flow field around a specific horizontal axis. The VS neurons can be divided into three functional groups. The VS1 to VS3 neurons are responsible for sensing pitch rotation of the self-motions. VS4 to VS7 neurons are specialized for roll rotation. The VS8 to VS9 neurons axes of rotation is between the main body axis and the transverse body axis.

Inevitability of a magnetic field in the Sun's radiative interior

Article Abstract:

The gas in the Sun's convective outer layer rotates more slowly in the polar regions than at the equator, but gas in the radiative zone rotates near-uniformly. The thin layer between these zone is called the tachocline, whose existence has not yet been explained by an fluid-dynamical mechanism. A dynamical nonlinear theory of the tachocline is presented.
