Fig. 4. Behavioral adaptation to 25 µmoll-1 ß,
-methylene
ATP is seen as a time-dependent decrease in ß,
-methylene ATP
avoidance response (% AR) (A) and in the amplitude of the
ß,
-methylene ATP-receptor potential (B). In both cases, it takes
approximately 15 min for adaptation to be complete. Therefore, adaptation can
be defined as a time-dependent loss of either the ß,
-methylene
ATP-AR or the ß,
-methylene ATP receptor potential. Each point
represents the mean ± S.D. of three trials.
