Blocking Assay:

Article Title: Rapid, activity-dependent intrinsic plasticity in the developing zebra finch auditory cortex
Article Snippet: .. To test whether blocking potassium currents would reverse intrinsic plasticity, recordings were performed in standard ACSF with an added cocktail of drugs to block fast synaptic transmission: 10 μ M ( ± )-3-(2-carboxyp-iperazin-4-yl)propyl-1-phosphonic acid (CPP; Alomone Labs), 20 μ M 6-cyano-7-nitroquinoxaline-2,3-dione disodium salt hydrate (CNQX; Alomone Labs), and 10 μ M (+)-bicuculline (Sigma). .. After the neuron became phasic (4–11 epochs), 2 mM 4-aminopyridine (4-AP; Sigma) was added to the perfusate.

Article Snippet: .. To test whether blocking potassium currents would reverse intrinsic plasticity, recordings were performed in standard ACSF with an added cocktail of drugs to block fast synaptic transmission: 10 mM (6) 3-(2-carboxypiperazin-4-yl)propyl-1-phosphonic acid (CPP; Alomone Labs), 20 mM 6- cyano-7-nitroquinoxaline-2,3-dione disodium salt hydrate (CNQX; Alomone Labs), and 10 mM (1)-bicuculline (Sigma). .. After the neuron became phasic (4–11 epochs), 2 mM 4-aminopyridine (4-AP; Sigma), or 100 nM a-dendrotoxin (a-DTX; Alomone Labs) was added to the perfusate.
