the inhibitory pattern of the tonic and phasic responses to phenobarbital was different from those to the other barbiturates , i.e . phenobarbital gradually inhibited both tonic and phasic responses , whereas other barbiturates suppressed significantly only the tonic response immediately after the administration of a relatively low dose ( 10 mg/kg ) but hardly inhibited the phasic response unless at higher doses ( 20 and 40 mg/kg ) .
