Chorda Tymponi 



Fig. 6. A tracing of summated neural responses recorded from the entire chorda 

 tympani nerve of one rat following chemical stimulation of the anterior portion 

 of the tongue. The record is continuous, and is arranged from top to bottom 

 of the figure. The record reads from left to right. The short horizontal lines 

 close to the beginning of each response indicate the duration of stimulus flow 

 through the tongue chamber. The dot near the end of each response indicates 

 the beginning of a distilled water wash. The summator rise time was 0.5 sec.
