abstract = {The combination of patch clamp recordings from two (or
more) synaptically coupled neurons (paired recordings) in
acute brain slice preparations with simultaneous
intracellular biocytin filling allows a correlated analysis
of their structural and functional properties. With this
method it is possible to identify and characterize both pre-
and postsynaptic neurons by their morphology and
electrophysiological response pattern. Paired recordings
allow studying the connectivity patterns between these
neurons as well as the properties of both chemical and
electrical synaptic transmission. Here, we give a
step-by-step description of the procedures required to
obtain reliable paired recordings together with an optimal
recovery of the neuron morphology. We will describe how
pairs of neurons connected via chemical synapses or gap
junctions are identified in brain slice preparations. We
will outline how neurons are reconstructed to obtain their
3D morphology of the dendritic and axonal domain and how
synaptic contacts are identified and localized. We will also
discuss the caveats and limitations of the paired recording
technique, in particular those associated with dendritic and
axonal truncations during the preparation of brain slices
because these strongly affect connectivity estimates.
However, because of the versatility of the paired recording
approach it will remain a valuable tool in characterizing
different aspects of synaptic transmission at identified
neuronal microcircuits in the brain.},
