Cyclothiazide was used to prevent desensitization of AMPA-receptors in hippocampal pyramidal neurons. The compound prolonged the decay time of multi-synaptic evoked excitatory currents in cell somata. No difference between effects at 22-25 C and 33-36 C was detected. Illustration, grey trace: control response normalized to response amplitude under cyclothiazide.
Used to prevent desensitization AMPA receptors in motor neurons. Used at concentration of 200 micromolar to measure whole cell current in motor neurons upon AMPA application.
