Figure 2. Spontaneous gastric mill rhythms over physiological temperature range.

(a) Extracellular recordings from the lgn and dgn at the temperatures indicated using the color code. (b) Spike rasters of LG from two preparations at the indicated colors to show the activity of these preparations over extended periods of time at the indicated temperatures. Traces in (a) and rasters in preparation 2 in (b) are from the same animal. Rasters with the same color are continuous recordings at the same temperature, and time wraps around the end of each raster and continues on the next line.

Figure 2—figure supplement 1. Spontaneous gastric activity in seven additional preparations.

Each panel shows rasters of the LG neuron from a single preparation at temperatures from 11°C to 30°C. Figure shows seven different preparations separated by black lines. LG was spontaneously active at temperatures as high as 30°C. Color of each row of raster indicates temperatures.
