The two potential differed in latency to peak and in width at half amplitude in a manner consistent with the different locus of termination of the two pathways on the granule cell dendrites. Both potentials were able to follow brief stimulus trains of 100 Hz, which suggests that they are monosynaptic. Medially elicited responses had their peak negativity approximately 100 to 180 \u03bcm deeper in the molecular layer than laterally elicited responses. Stimulation at short intervals along a dorsomedial to ventrolateral track in the angular bundle yielded a step function rather than a continuum of EPSP peak latency and half\u2010width, in agreement with Hjorth\u2010Simonsen's ('72) evidence for the separateness of the two pathways. Both pathways were able to induce granule cell discharge. Laterally elicited spikes, however, were delayed. Stimulation at intermediate locations frequently elicited double spikes from granule cell population. Population spikes elicited by either pathway were inhibited for as long as 100 msec after a single discharge. Both pathways showed facilitation with double stimuli at short intervals, and both showed post\u2010tetanic potentiation lasting at least 30 minutes. Under conditins where it could be shown that the two pathways at least partially converged onto the same granule cells, the response of one pathway did not increase when long lasting potentiation was induced on the other.<\/jats:p>","DOI":"10.1002\/cne.901750404","type":"journal-article","created":{"date-parts":[[2004,12,28]],"date-time":"2004-12-28T19:56:20Z","timestamp":1104263780000},"page":"439-453","source":"Crossref","is-referenced-by-count":229,"title":["Physiological identification and analysis of dentate granule cell responses to stimulation of the medial and lateral perforant pathways in the rat"],"prefix":"10.1002","volume":"175","author":[{"given":"B.
