Role of calcium ions in processes of serotonin-induced modulation of neuronal response to acetylcholone application in Helix pomatia

The role of calcium ions in modulating serotonin action on acetylcholine (ACh) response in nonidentified and identified (LPa3 and RPa3) neurons ofHelix pomatia was investigated using voltage-clamping at the neuronal membrane. Exposure for 1 min to serotonin prior to ACh application reduced response to ACh in neuron LPa3 and raised it in RPa3. The same two… (More)
