Summary
-
(1)
Hydrogen ions may convert an excitatory effect into an inhibitory one.
-
(2)
Calcium, sodium chloride and caffeine may produce reversal effects.
-
(3)
Presence of tone alters an excitatory effect into an inhibitory one.
-
(4)
Anions may convert an inhibitory effect into an excitatory one, and cations may produce an opposite effect.
-
(5)
Reversal effects are also produced by adaptation, fatigue, inexci-tability and change of length.
