Colliculus Inferior GABAergic Principal Cell
|
Winer and colleagues (1996) first described that GABAergic neurons project to the medial geniculate body in cat. Peruzzi et al. (1997) showed that the cell type is also found in rats, and sends action potentials more rapidly than glutamatergic IC neurons. Ito and colleagues (2009) showed that the cell type is the largest neuron in the IC and receives dense VGLUT2-positive axosomatic terminals on the cell body. Other cell types such as glutamatergic neurons and small GABAergic neurons do not have such endings.

Colliculus inferior principal cell
|
Around 80% of neurons in the inferior colliculus (IC) is glutamatergic (Ito and Oliver, 2012). They express vesicular glutamate transporter (VGLUT) 2 but not VGLUT1 or VGLUT3 (Ito and Oliver, 2010, 2011). Their main target is the medial geniculate body although they send axons to most auditory brainstem nuclei. Since majority of IC neurons are disc-shaped, which extend their dendrite parallel to isofrequency laminae (Oliver, 1984), majority of glutamatergic neurons are likely to be disc-shaped. Stellate neurons, which are less common and extend dendrite perpendicular to isofrequency laminae, also project to the medial geniculate body (Oliver, 1984).

Colliculus superior deep vertical fusiform cell
|
Deep vertical fusiform cells have cell bodies about 20 micrometers wide and their dendrites extend from the upper margin of the zone of vertical cells to the depth of the zone of optic fibers perhaps even deeper. The superficial and deep fields are usually notably different in the manner in which the dendrites branch and spread, the over to all size of the fields, the shapes of the fields, the type and density of spines, and the caliber of the dendrites.

Colliculus superior intermediate vertical fusiform cell
|
The intermediate vertical fusiform cells have cell bodies 12 to 18 micrometers in diameter in the upper portion of the zone of vertical cells and their dendritic fields extend from the collicular surface to the deep margin of the zone of vertical cells (fig. 12b, 13). Intermediate vertical fusiform cells most often have a superficial field with relatively fewer spines, straighter, more even caliber dendrites that branch less often but more equally than those in the deep field of the same cell (figs. 12b, 13).

Colliculus superior inverted pyramidal cell
|
The inverted pyramidal cell is similar to the pyramidal cell except that the cell body lies within the deep portion of the zone of horizontal cells. The superficial field is a circumsomatic field and the deep field is elongated to reach into the deeper portion of the zone of vertical cells. The cell body is about the size of an intermediate vertical fusiform cell soma. The axon is similar, but more apt to have collaterals to the superficial zones. Inverted pyramidal cells fall within the definition of the narrow field vertical cells.

Colliculus superior piriform cell
|
The piriform cells have ovoid or cup shaped cell bodies, 10 to 15 micrometers in diameter, located within a narrow lamina along the deep margin of the zone of horizontal cells. The restriction of the piriform cell somata to the boundary between the zone of horizontal cells and the zone of vertical cells is remarkably accurate and consistent. The piriform cells give rise to 2 to 5 dendrites from the superficial surface, which course through the zone of horizontal cells to terminate just beneath the surface. As the ascending dendrites approach the surface they branch more frequently, almost always by equipartition, to form a complicated intermingling bouquet of slowly tapering dendrites, 150 to 350 micrometers in width and slightly less than 200 micrometers in depth. The axon most frequently takes its origin from the base of the soma, but sometimes it arises from one of the low order dendrites. From its origin the axon runs immediately down through the zone of vertical cells, occasionally with collaterals which may arborize within the superficial laminae. The axon is thin and smooth, occasionally with en passant varicosities.

Colliculus superior pyramidal cell
|
Pyramidal cells are similar to vertical fusiform cells in most respects. They have a vertically elongated cell body, about 15 micrometers in transverse diameter, in the deeper half of the zone of vertical cells. The dendritic field is narrow and cylindrical, 100 to 250 micrometer in diameter, and extends from the upper margin of the zone of horizontal cells to the lower margin of the zone of vertical cells, about 500 micrometers. Rather than having superficial and deep fields, the pyramidal cell has the deep field reduced to a circumsomatic field, or a diminuitive basal field, and the superficial field is relatively elongated to accord with the deeper cell body. Pyramidal cells are usually multipolar, with one or two thick apical dendrites, which branch several times on the way to the surface, particularly in the upper portion of the zone of horizontal cells, and several smaller dendrites which form a small field about the cell body. It is of interest that smooth pyramidal cells tend to have two primary dendrites, like smooth vertical fusiform cells. The axon takes its origin from the soma or a low order dendrite and runs down into the deep zones. It is smooth and thin, about like that of the vertical fusiform cells.

Colliculus superior stellate neuron
|
The third major category of cells in the superior colliculus is the stellate cell. The cells are defined by the lack of overall orientation to the dendritic fields which extend symmetrically from the cell body. Stellate cells are multipolar with dendrites arising from any portion of the cell body. The dendrites may range anywhere from gnarled to radiate with the gnarled spiny cells most frequent in the zone of horizontal cells and the smooth radiate cells increasingly more frequent in the deeper zones until they are almost the only cell type in the zones below the stratum opticum. The dimensions of the cell bodies and dendritic fields are comparable to those of other cells in the same zone and the dendritic field is generally contained within the same zone as the cell body. The axons of stellate cells have both local and/or distant distributions and a morphology characteristic of intrinsic axons. As with all the other cell types, the axon may take its origin from the cell body or a low order dendrite.

Colliculus superior wide field vertical cell
|
There are two similar populations in the group of wide field vertical cells. The first lies in the deep margin of the zone of vertical cells where it looks very similar to the piriform cells relative to the zone of horizontal cells. Cajal called these the ovoid or triangular cells. The second population has its cell bodies distributed primarily to the upper portion of the zone of optic fibers. Cajal called these triangular or stellate cells. Cajal's nomenclature is rather bulky and, though descriptive, somewhat confusing because stellate cells are a distinct cell type in the nomenclature of this paper and triangular occurs in both names. For reasons developed below, the ovoid or triangular cells or wide field cells of the zone of vertical cells will be called Type II ganglion cells and the triangular or stellate cells or wide field cells of the zone of optic fibers will be called Type III ganglion cells. Type I ganglion cells are the piriform cells. Collator note: we assumed this class of neurons as projection neurons, because at least several subpopulations project to visually related areas. See Sefton et al., 2005; Mason and Groos, 1981; Mackay to Sim et al. 1983; Okoyama and Kudo, 1987).
