Example: "In this project, we need someone to act as pacemaker to ensure that we stay on track and meet our deadlines."

Since STN neurons are capable of rebound firing upon release from GABA-mediated hyperpolarization [25], this arrangement suggests that reciprocally connected groups of STN-GPe neurons may be able to act as pacemaker circuits.
It was even suggested that all uterine smooth muscle cells have the capacity to act as pacemaker cells, and thereby initiate the contractions [ 41].
Similar to the gut, C-kit+ cells in the human bladder possibly act as pacemaker cells from which spontaneous calcium transients originate [ 28].
Along with serving as defibrillators, these advance devices also act as pacemakers, helping weakly beating hearts maintain normal rhythms.
Controlled surface heterogeneities can gradually suppress certain types of reaction patterns; they can also act as "pacemakers" for the catalytic surface.
While computer chips keep shrinking, the size of gadgets is still limited, in part, by relatively large pieces of quartz that act as pacemakers for electronic circuits.
The aim of this study was to determine if embryonic stem cell derived cardiomyocyte aggregates (ESdCs) can act as pacemakers in spontaneously active cardiomyocyte preparations when their connexin isoform expression is tuned toward a more sinus nodal phenotype.
They also act as pacemakers should their team leader crash or struggle on a climb.
They therefore act as pacemakers of intestinal peristaltic activity [ 1, 2].
It is clear that the individual SCN neurons can act as pacemakers; when dispersed in culture they independently continue to keep time (Welsh et al., 1995).
In the GI tract, they act as pacemakers that generate and propagate slow waves, as mediators between the enteric nervous system and smooth muscle, and as stretch sensors [ 1, 2].
