Parvocellular is to magnocellular as
WebThe PVN contains magnocellular neurosecretory cells whose axons extend into the posterior pituitary, parvocellular neurosecretory cells that project to the median eminence, ultimately signalling to the anterior pituitary, and several populations of other cells that project to many different brain regions including parvocellular preautonomic cells … WebParvocellular neurons comprise a greater proportion of the cell population in the PVN compared to the supraoptic nucleus where magnocellular cells predominate. While the passive properties of parvocellular and magnocellular cells are not dissimilar, the two cell types can be distinguished on the basis of their active conductances.

WebJan 1, 1985 · As a result, in the parvocellular division as a whole, the average latency to ipsilateral stimulation is shorter than that to contralateral stimulation. The optic tract exhibits a dorsal-to-ventral progression of onset latency and oscillation frequency consistent with a dorsal/ventral segragation of the inputs to parvo- and magnocellular layers.
