QUANTAL ANALYSIS AND LONG-TERM POTENTIATION

Quantal analysis is useful for assessing the pre-and/or post-synaptic locus of the expression of long-term tetanic potentiation with the con dition, however, that the studied synaptic potentials have been evoked by single cell stimulations, as is the case with paired recordings of identified neurons. The application of this methodology, primarily wi th indirect criteria, has produced conclusions which dance back and fo rth across the synaptic cleft. ((C) Academie des sciences/Elsevier, Pa ris.)
