The brain temperature of trout (Salvelinus fontinalis) was altered by perfusion of the gills with warm or cool water. Neuronal activity was recorded with microelectrodes. Twelve neurons responded to an increase in temperature with increased activity, and five neurons responded to a decrease in temperature with an increase in activity.
