Habituation and sensitization in an aneural cell: some comparative and theoretical considerations.
Several shorter- and longer-term non-associative modifications in behavior are known to occur in neural as well as aneural systems. Thus neural investment is not essential for these phenomena to occur. Cellular studies of these behaviors in Protozoa, where a single cell is also a whole organism, may be useful in investigating the evolution of mechanisms underlying these plastic behavioral changes.
