Definitions

  • WordNet 3.6
    • n chemotaxis movement by a cell or organism in reaction to a chemical stimulus
    • ***
Webster's Revised Unabridged Dictionary
    • Chemotaxis (Biol) The sensitiveness exhibited by small free-swimming organisms, as bacteria, zoöspores of algæ, etc., to chemical substances held in solution. They may be attracted (positive chemotaxis) or repelled (negative chemotaxis).
    • ***
Century Dictionary and Cyclopedia
    • n chemotaxis The locomotion of organisms or of cells in relation to chemical substances, or the property of certain chemical substances to attract or repel living cells at the point of action: in the first instance there is positive chemotaxis, in the second negative chemotaxis. The peculiar response of the white blood-corpuscles to chemotactic stimulation is of fundamental importance in the defense of the animal organism against bacterial invasion.

On a Condition for Intracellular Adaptive Dynamics for Chemotaxis
In other words, the existence of memory in the internal state makes chemotaxis possible.
On a Condition for Intracellular Adaptive Dynamics for Chemotaxis
However, this is true only for short-term behavior of chemotaxis.
On a Condition for Intracellular Adaptive Dynamics for Chemotaxis
All simulations for other parameters show that the elements assemble in the region x ≥ 0, that is, the chemotaxis works well for τs <∼ τ ∗ <∼ τa .
On a Condition for Intracellular Adaptive Dynamics for Chemotaxis
Now, ˜τs , the threshold beyond which the (renormalized) Oosawa condition ˜τs <∼ τ ∗ is satisfied, is expected to give a criterion for chemotaxis.
