“…Sagittal sections demonstrate that the MGI occupies a large volume of the MGB, especially posteriorly, where it expands to encapsulate the caudal pole of the MGV. Caballero-Bleda et al (1991a) have also described an internal nucleus in the rabbit MGB with a topographic location and cytoarchitecture similar to the MGI of the present study. Their demonstration that the MGI is biochemically distinct (containing weak AChE and moderate NADH diaphorase activities) from other MGB subdivisions is further support for the existence of MGI as a separate subdivision (Caballero-Bleda et al, 1991a).…”

“…The ventral, dorsal, and internal nuclei correspond well with previous tripartite organizational schemes of the rabbit MGB (Rose, 1942;Giolli and Gutherie, 1971;Geeraedts, 1978;Jones, 1985). Although a magnocellular medial nucleus is not usually described as a separate subdivision of the rabbit MGB (Jones, 19851, a similar nucleus has been reported in the chemoarchitectonic study of Caballero-Bleda et al (1991a).…”

“…In addition, the packing density of cells in VL is only slightly lower than that of the MGV. In their study of the differential distribution of AChE and NADH-diaphorase activities in the rabbit MGB, Caballero-Bleda et al (1991a) also recognized a crescent-shaped ventrolateral portion of the MGV characterized by decreased NADH activity and a lower cell density relative to the main body of the nucleus.…”

The complementary pattern of immunohistochemical staining for the calcium-binding proteins parvalbumin (PV) and calbindin D-28k (CB) was used to delineate four major subdivisions of the rabbit medial geniculate body (MGB). PV immunoreactivity predominates in the ventral and medial divisions, whereas CB-immunoreactive cells characterize the dorsal and internal divisions. The ventral nucleus is strongly PV+ due to dense neuropil labeling and moderately labeled somata. The medial nucleus contains both medium-sized and large PV+ somata, as well as thick PV+ axons and terminals. The wedge-shaped internal nucleus composed of densely labeled CB+ cells, separates the dorsal and ventral nuclei rostrally, and expands caudally to encapsulate the posterior MGV. Large multipolar CB+ neurons with radiate dendrites characterize the dorsal nucleus. The differential expression of PV and CB also distinguishes the deep dorsal and superficial dorsal subnuclei in the dorsal division and a ventrolateral component in the ventral division. A comparison with studies of MGB connectivity in a variety of species suggests that PV immunoreactivity is highest in subdivisions that receive a substantial input from the central nucleus of the inferior colliculus and that project to primary auditory cortex. In contrast, CB immunoreactivity characterizes nuclei that receive input primarily from other sources, such as the paracentral nuclei of the inferior colliculus, the lateral tegmentum, and the spinal cord, and that project to secondary auditory areas. The ability of calcium-binding protein immunohistochemistry to delineate neuronal compartments across indistinct cytoarchitectonic borders makes it a powerful tool for guiding future connectional and physiological studies of the MGB.

“…Two nuclei were considered significantly different for a particular technique if they do not belong to the same group. Two nuclei are significantly different if they are not tied by a black line as AChE, NADPHd and Calcium binding proteins led to differentiate an internal division in the medial geniculate body of the rabbit (Caballero-Bleda et al, 1991;deVenecia et al, 1995). Although most reports agree that the rat is composed of the same nuclei, no agreement has been reached regarding the location and extension of each one.…”

The chemoarchitecture of the pretectal complex of the rabbit was examined in sections stained by acetylcholinesterase (AChE) and reduced nicotinamide adenine dinucleotide (NADH) diaphorase in the coronal, horizontal and sagittal plane. Twelve different subdivisions can be identified in the rabbit prectectum on the basis of the distribution of both histochemical markers. According to the standard terminology, the pretectal complex of the rabbit consists of: the nucleus of the optic tract; the anterior, posterior, olivary and medial pretectal nuclei; the nucleus of the posterior commissure; the periventricular subcommissural gray; the suprageniculate and internal suprageniculate nuclei, and the dorsal, lateral and medial terminal nuclei of the accessory optic system. The combined use of several sectioning planes and the histochemical mapping of AChE and NADH diaphorase have been of value in resolving the structural limits within transitional regions of the pretectum.
