In experiments on the isolated frog spinal cord the relationship between the statistical properties of the unitary EPSP and the number of synaptic contacts was determined when the primary afferent fibre used in evoking the EPSP and the motoneuron in which it was recorded were both stained with HRP.
Double-barrelled microelectrodes, sensitive to quaternary ammonium ions, were used for simultaneous measurements of the intracellular free concentrations of choline ([Ch],) or tetramethylammonium ([TMAIJ as well as membrane potential (Em) in neuropile glial cells of the leech, Hirudo medicinalis. Ba
