basket neuron | Chan-Palay (Chan-Palay) | Compared with the granule cell, the basket cell is quite complicated. It receives sysnapses from parallel fibers and to a limited extent from climbing fibers, but it devotes its entire axonal output to the Purkinje cells with the possible exception of a few contacts on other basket cells and Golgi cells. A large number of widely dispersed parallel fibers converge on its dendrites, but its axon sends divergent impulses to only a small number of Purkinje cells. The basket cell has a roughly pyramidal or ovoid shape, and it lies in the lower third of the molecular layer with its long axis parallel to the Purkinje cell layer in the sagittal plane. In Nissl preparations little more can be seen of it than its triangular or oval cell body, about 10 micrometers long....Ramon y Cajal (1888a and b) was the first to discover the characteristic terminal plexus elaborated around the Purkinje cell body by the axons of these cells. He named this formation the pericellular nest (nid pericellulaire). His finding was quickly confirmed by Kolliker (1890), who referred to the same structure as a "fiber basket" (Faserkorb), and to the cells that gave rise to it as "basket cells" (Korbzellen). | includes | The standard division of these cells into basket and stellate cells, for example, depends principally on two features, their different depths (basket cells are deeper than stellate cells) and, importantly, whether their axons contribute basket endings onto somata of nearby Purkinje cells (Eccles et al., 1967; Palay and Chan-Palay, 1974)...Consistent with previous classification schemes (Eccles et al., 1967; Palay and Chan-Palay, 1974) the particular feature that is most striking is the dependence on depth for the generation of the basket-type ending (Fig. 8). However, our analysis shows that this property actually varies smoothly with depth (Fig. 9). Collator note: see also Table, page 369. | Sultan F. & Bower J.M. | Mihail Bota |

stellate neuron | Chan-Palay (Chan-Palay) | The stellate cells compose a class of small polymorphous neurons lying in the outer two thirds of the molecular layer. They were described by a number of early authors, Fusari (1883), Ponti (1897), Smirnow (1897), in addition to Ramon y Cajal (1889b), who in his great book on the nervous system (1911) gave Smirnow the credit the most detailed and exact account of the different kinds of stellate cells. | includes | The standard division of these cells into basket and stellate cells, for example, depends principally on two features, their different depths (basket cells are deeper than stellate cells) and, importantly, whether their axons contribute basket endings onto somata of nearby Purkinje cells (Eccles et al., 1967; Palay and Chan-Palay, 1974)...Consistent with previous classification schemes (Eccles et al., 1967; Palay and Chan-Palay, 1974) the particular feature that is most striking is the dependence on depth for the generation of the basket-type ending (Fig. 8).

superficial short axon stellate cell | Chan-Palay (Chan-Palay) | They can be quite superficial, lying just within the neuroglial end feet that form the limiting membrane under the pia. The superficial stellate cells have small somata about 5-10 micrometers in diameter. The appearance of their dendrites in Golgi preparations is typical of all stellate cells. They are irregular in caliber and very contorted, eith many abrupt changes in direction, as if twisting and hooking around invisible obstacles in their course. The dendritic trees of the steallate cells near the pial surface fall into two patterns. First, major dendrites can originate from opposite sides of the cell body, giving the cell a somewhat bipolar appearance. These dendrites can extend either horizontally, that is, parallel with the pial surface (Fig. 187A) or vertically (Fig. 188A, B). The axon of the stellate cell originates from the cell body (Fig. 186) or, less often, from a major dendrite (Fig. 187A, B, 188 A-C, and 190), by way a barely perceptible axon hillock. Thin, crooked collaterals arise from it at approximately right angles or somewhat less. In our preparations they are short, tenuous, varicose threads resembling strands of loosely strung, imperfect pearls (Figs. 186 to 191). | includes | The standard division of these cells into basket and stellate cells, for example, depends principally on two features, their different depths (basket cells are deeper than stellate cells) and, importantly, whether their axons contribute basket endings onto somata of nearby Purkinje cells (Eccles et al., 1967; Palay and Chan-Palay, 1974)...Consistent with previous classification schemes (Eccles et al., 1967; Palay and Chan-Palay, 1974) the particular feature that is most striking is the dependence on depth for the generation of the basket-type ending (Fig. 8).

deeper long axon stellate cell | Chan-Palay (Chan-Palay) | In the middle third of the molecular layer and deeper, stellate cells with very long axons are encountered. These are distinct from the superficial short axon cell, and constitute a second type (Figs. 187C, !88D, 190, and 191). Their major dendrites emerge from the cell body and give rise to a large number of contorted branches that radiate outwards into the molecular layer, dividing frequently. Resembling the dendrites of the more superficial stellate cells, they also have few spiny appendages. The axon can extend for lengths of up to 450 micrometers (Fig. 188D), always running in the parasagittal plane and slipping through the fan-like arborescence of the Purkinje cell dendrites. | includes | The standard division of these cells into basket and stellate cells, for example, depends principally on two features, their different depths (basket cells are deeper than stellate cells) and, importantly, whether their axons contribute basket endings onto somata of nearby Purkinje cells (Eccles et al., 1967; Palay and Chan-Palay, 1974)...Consistent with previous classification schemes (Eccles et al., 1967; Palay and Chan-Palay, 1974) the particular feature that is most striking is the dependence on depth for the generation of the basket-type ending (Fig. 8).
