“…This observation was later confirmed by retrograde labeling of different classes of efferent collicular neurons (Castiglioni et al, 1978;Huerta et al, 1981;Murray and Coulter, 1982;Yamasaki et al, 1986). In parallel, there is a patchy innervation of most, if not all, of the collicular afferents (from cortex, Goldman and Nauta, 1976;Kü nzle and Akert, 1977;Leichnetz et al, 1981;Segal et al, 1983;Clemo and Stein, 1983; from subcortical sensory relays, Kudo and Niimi, 1980;Tashiro et al, 1980;Huerta et al, 1981;Kudo, 1981;Huerta and Harting, 1982;Harting and Van Lieshout, 1991; from basal ganglia, Jayaraman et al, 1977;Graybiel, 1978a;Beckstead et al, 1979;Harting and Van Lieshout, 1991;Redgrave et al, 1992; from cerebellum, Kawamura et al, 1982; from hypothalamus, Rieck et al, 1986). Patches in the intermediate layers are regularly described in the frontal plane as a series of groups of either terminals or neurons with generally increased size from medial to lateral SC.…”

“…The intermediate layer of the SC has also been shown to receive projections from the nucleus interpositus posterior and the lateral cerebellar nucleus (Roldan and ReinosoSuarez, 1981;Kawamura et al, 1982). In addition to the cerebellar inputs, the intermediate layer of the SC receives projections from the cervical spinal cord, the parabrachial nucleus, the cuneiform nucleus, the substantia nigra, and the posterior commissure nucleus of the pre- tectum (Edwards et al, 1979).…”

“…The intralaminar nuclei are known to receive projections from the nucleus interpositus and the lateral nucleus of the cerebellum (Sugimoto et al, 1981;Hirai et al, 1982;Kawamura et al, 1982), and were reported to play a role in eye movement signal processing (Schlag-Rey and Schlag, 1977). It is also well known that the intralaminar nuclei receive projections from the intermediate layer of SC (Graham, 1977).…”

The ventral lateral geniculate nucleus is a small extrageniculate visual structure that has a complex cytoarchitecture and diverse connections. In addition to small-celled medial and lateral divisions, we cytoarchitectonically defined a small-celled dorsal division. A large-celled intermediate division intercalated between the three small-celled divisions, which we divided into medial and lateral intermediate subdivisions. In WGA-HRP injection experiments, the different cytoarchitectonic divisions were shown to have connections with different nuclei. The medial division was reciprocally connected to the pretectum and projected to the superficial layers of the superior colliculus and the intralaminar nuclei. The medial intermediate division received projections from the intermediate layer of the superior colliculus and the lateral and interpositus posterior cerebellar nuclei, and projected to the intermediate layer of the superior colliculus, the periaqueductal gray of midbrain, and the intralaminar nuclei. The lateral intermediate divisions received projections from the pretectum, the intermediate layer of the superior colliculus, and the lateral and interpositus posterior cerebellar nuclei, and projected to the pretectum, superficial layers of the superior colliculus, and the pulvinar. The lateral division received projections from superficial layers of the superior colliculus and had reciprocal connections with the pretectum. The dorsal division received projections from the pretectum and had reciprocal connections with the periaqueductal gray of midbrain. The different cytoarchitectonic divisions of the ventral lateral geniculate nucleus are thus suggested to play different functional roles related to vision, eye and head movements, attention, and defensive reactions.

“…That is, the input from the dorsal column nuclei terminates within re gions of the pretectal complex that do not receive any visual input, specifically in the anterior and posterior pretectal nuclei. Cerebellar input to the pretectal complex arises from the deep cerebellar nuclei, i.e., the lateral nucleus [Kawamura et al, 1982], It has been speculated that these pathways subserve an integrative role in sensorimotor processing, such as the con trol and coordination of activity in large muscle groups during tactually guided movements [K.J. Berkley, pers.…”

In the present report, conflicting results regarding the pretectal complex and accessory optic system of primates are discussed. Subsequently data are presented and used in an attempt to clarify some of the issues. The retinal projections to the pretectal complex and accessory optic system of the tree shrew and squirrel monkey were examined using anterograde autoradiographic methods. These data demonstrate that, following intraocular injections of ³H-proline or ³H-fucose in the tree shrew, silver grains are apparent bilaterally over the pretectal olivary nucleus and the anterior and posterior pretectal nuclei and contralaterally over the nucleus of the optic tract. Following intraocular injections of the ³H-tracer in squirrel monkeys, dense transported label is observed bilaterally over the pretectal olivary nucleus and the nucleus of the optic tract with sparse label over the posterior and medial pretectal nuclei. In both the tree shrew and squirrel monkey, a differential retinal projection is observed, chiefly contralaterally, to all accessory optic terminal nuclei (i.e., the dorsal, lateral and medial terminal nuclei).
