0 a type of resistor in which resistance varies with temperature
Temperatures were measured using four additional matched and calibrated thermistors embedded in the copper near the fluid.
Pressure is measured with differential pressure sensors and the temperature of the cell is measured with a thermistor.
Water currents set up by respiration were monitored by a small glass-encapsulated thermistor placed in front of the fish's snout.
For each run the resistances of both thermistors were measured with no heat flow, as described below.
The electrical leads to the coil and thermistors are very fine (no. 40) wire so that heat leak is minimized.
Here u and are the temperature and the electric potential in the thermistor, respectively, and (u) is the electric conductivity.
From the thermistor traces the amplitude modulation period could be measured directly and is plotted on the same figure.
The temperature was monitored with a thermistor in the bath close to the retina.
