WebHowever a great number of NPY immunoreactive neurons were found in the white matter under the IPL cortex. The following types of NPY immunoreactive neurons were found: Cajal-Retzius, pyramidal, inverted pyramidal, "double bouquet" (bitufted), rare type 6, multipolar nonspinous, bipolar, voluminous "basket", and chandelier cells. Webarbors suggests that bitufted cells can control the excitation within a cortical column and, possibly in the supragranular lay-ers, also between columns (Kaiser et al., 2001). The efficacy of synaptic connections between pyramids and bitufted cells is low (Reyes et al., 1998), but EPSPs strongly facil-

WebJan 15, 2005 · Voltage-gated K+ channels perform many functions in integration of synaptic input and action potential (AP) generation. In this study we show that in bitufted interneurones from layer 2/3 of the somatosensory cortex, the height and width of APs recorded at the soma are sensitive to changes in the resting membrane potential, … WebMar 1, 2001 · In bitufted interneurones evoked delayed EPSCs can be investigated with minimal interference from spontaneous EPSCs, which occur at a very low frequency. In multipolar cells, which have a relatively high rate of spontaneous activity, we compared the number of spontaneous EPSCs before an AP with the number of asynchronous events … WebMay 6, 2005 · The efficacy and short-term modification of neocortical synaptic connections vary with the type of target neuron. We investigated presynaptic Ca 2+ and release probability at single synaptic contacts between pairs of neurons in layer 2/3 of the rat neocortex.
