Sentence examples for persistent stimuli from inspiring English sources

This type of behavior occurs in signal pathways that become desensitized or adapt to persistent stimuli.

In gene transcription regulation networks, the feedforward loop was proposed to carry out information processing functions such as filtering out fluctuations and responding only to persistent stimuli [ 7].

Persistent stimuli that activate inflammatory pathways and elicit a microtubule stabilization response may provide selective pressure for mutations that suppress TTL activity and/or upregulate the TCP.

Specifically, a motif called "feed-forward loop" found in transcriptional regulatory networks was shown to have an important role in the regulation of genes in response to persistent stimuli in contrast to transient signals [ 4, 5].

In particular, R. sphaeroides seems to have slower adaptation to persistent stimuli [ 18] and gives an 'inverted' chemotaxis response (i.e. increasing attractant concentration causes an increase in tumbling frequency), when grown under aerobic conditions [ 19].

In general, the adjustment process involves four parts: (1) a need or motive in the form of a strong persistent stimulus, (2) the thwarting or nonfulfillment of this need, (3) varied activity, or exploratory behaviour accompanied by problem solving, and (4) some response that removes or at least reduces the initiating stimulus and completes the adjustment.

That is, at least one of the concepts must return to near its basal level in the presence of a persistent stimulus.

Receptor activity adapts to persistent stimulus through methylation and demethylation of the receptors by the enzymes CheR and CheB, respectively.

Formation of granuloma occurs in response to a persistent stimulus and has also been linked with TNF and induction of host matrix metalloproteinase (MMPs) production in tuberculosis [ 27].
