The extra spike appears to arise from a large depolarizing afterpotential crossing the falling threshold several milliseconds following a spike; extra spikes themselves may generate further extra spikes in a similar manner, generating burst patterns which are strikingly similar to those of epileptic neurons. date: 1975 date_type: published publication: Brain Research volume: 83 pagerange: 498-503 refereed: TRUE citation: Calvin, William H. and Sypert, George W.
