WebJan 30, 2024 · The perforant pathways, originating from pyramidal neurons in layer II of the EC, are divided into lateral perforant path (LPP) and medial perforant path (MPP). Each pathway has different anatomical and functional properties depending on the afferents in either of two mentioned projections [ 14 ]. WebApr 13, 2024 · One, the lateral perforant path (LPP), originates in the lateral entorhinal cortex (LEC), while the other, the medial perforant path (MPP), originates in the medial entorhinal cortex (MEC); they terminate in the outer and middle molecular layers of the DG, respectively (Young et al. 1997; Nishimura-Akiyoshi et al. 2007 ).

WebLocalization of the outer and middle molecular layers of DG is confirmed by the average CSD of the evoked response to stimulating the medial perforant path (MPP; Figure 2 C, right). The DS L amplitude is larger than the DS M ( Figure 2 D; paired t 8 = 2.87, p = 0.02), while the DS M width is greater than the DS L (paired t 8 = 8.56, p = 10 −5 ). WebIn one study, Ferbinteanu et al. (1999) showed that lesions of the medial perforant path disrupted water maze learning, whereas lateral perforant path lesions had no effect. In a more recent study based on the idea that the medial perforant path (MPP) input into the CA3 mediates spatial information via activation of NMDA receptors and the ...
