Menthol and icilin enhancement of glutamatergic transmission is independent of voltage dependent calcium channels. Bar chart showing the change in miniature EPSC (mEPSC) rate produced by menthol (400 μM), icilin (100 μM) and elevated external K+ (25 mM), in normal ACSF (control), in ACSF containing Cd2+ (30 μM), and in Ca2+-free ACSF (0 Ca2+). Data are expressed as a percentage of the pre-menthol, icilin and high K+ levels, and averaged across all neurons. The number in the bars represent the total number of neurons tested under each condition.
