gradient perception (medicine) and prescribe (oh)


gradient perception (medicine)


gradient perception
<cell biology> Problem faced by a cell that is to respond directionally to a gradient of, for example: a diffusible attractant chemical.

In a spatial mechanism the cell would compare receptor occupancy at different sites on the cell surface, a temporal mechanism would involve comparison of concentrations at different times, the cell moving randomly between readings.

In pseudospatial sensing, the cell would detect the gradient as a consequence of positive feedback to protrusive activity if receptor occupancy increased with time as the protrusion moved up gradient. Few cell types have been unambiguously shown to detect gradients.
