title: Isolation of neurons suitable for patch-clamping from adult mammalian central nervous systems.
abstract: A method is described for the isolation of neurons from defined regions of the mammalian central nervous system, by a combination of mechanical and enzymatic means. The procedure liberates neurons free of cellular debris and glial investments, allowing the formation of giga-ohm seals with patch clamp electrodes. The characteristic morphology of neurons is maintained, together with the diversity of active channels evident in the intact nervous system.
