Figure 5. Age-dependence of effects of Iberiotoxin on spontaneoeuos firing of Purkinje cells.

Figure 5

A,Open symbols show the age of animals in which iberiotoxin altered tonic firing to irregular burst firing (T->Ir Burst; n=7), tonic firing to the trimodal pattern of activity (T->Pattern; n=6), and cells that in the absence of iberiotoxin exhibited the trimodal modal pattern of activity (Pattern; n=15). Filled symbols show the average age (±S.E.M.). The average ages of the three groups were significantly different from each other. B, The relationship between the age of animals and the extent to which iberiotoxin increased their firing rate.
