“…Furthermore, fibers ascending in the medial longitudinal fasciculus have even been suggested to exert indirect influences on the ocular muscles by means of pathways involving the interstitial nucleus of Cajal and other midbrain nuclei (Szentagothai and Schab 1956;Hyde and Toczek 1962;Markham et al 1966). Although, in this study such additional neuronal pathways were not found, other premotor interneurons, probably local non-spiking interneurons, might be interposed between the local spiking interneurons and oculomotor neurons.…”

1. In the crayfish brain, the responses of local spiking interneurons to body roll simulated by bending of statocyst hairs, were investigated with intracellular recording and staining techniques. The neurons had two separate branching portions in the protocerebrum and the deutocerebrum. They were named as type-I local neurons and further classified into 5 types (ac-U, vplc-U, vplc-B, vupc-U, vupc-B). 2. Vupc-U neurons showed excitatory responses and vplc-U neurons showed inhibitory responses to inward hair deflection of the statocyst ipsilateral to their deutocerebral branches. The other 3 types were of mixed populations of the interneurons showing either excitatory or inhibitory responses to the stimulation. 3. Of 10 type-I local neurons showing excitatory responses to inward hair deflection, 6 interneurons had output effects on oculomotor and/or descending neurons. All these 6 interneurons showed large EPSPs and much higher frequency of spikes to the hair stimulation than those of the other 4. All 8 type-I local neurons that showed inhibitory responses had no output effects. 4. Type-I local neurons controlled two equilibrium responses, compensatory eye movement and righting reflex, either simultaneously or independently.

“…no known oculomotor function (Buttner-Ennever and Buttner, 1988), but LTN connections with the interstitial nucleus of Cajal and nucleus of posterior commissure may serve compensatory vertical and torsional eye and neck reflexes evoked during motion of the visual surround. This follows from the physiological response properties of the AOS neurons and from physiological studies on the interstitial nucleus of Cajal showing (1) head rotation in the transverse plane with electrical stimulation of the nucleus (Hassler and Hess, 1954;Hyde and Toczek, 1962) and (2) tilting of head to side opposite lesion of the interstitial nucleus in monkey and cat Fukushima et al, 1978). These physiological findings are consistent with anatomical observations showing that the interstitial nucleus of Cajal projects to portions of the oculomotor nucleus involved with vertical movement of the eyes Steiger and Buttner-Ennever, 1979) and to neck motoneurons (Fukushima et al, 1978).…”

The connections of the lateral terminal nucleus (LTN) of the accessory optic system (AOS) of the marmoset monkey were studied with anterograde 3H-amino acid light autoradiography and horseradish peroxidase retrograde labeling techniques. Results show a first and largest LTN projection to the pretectal and AOS nuclei including the ipsilateral nucleus of the optic tract, dorsal terminal nucleus, and interstitial nucleus of the superior fasciculus (posterior fibers); smaller contralateral projections are to the olivary pretectal nucleus, dorsal terminal nucleus, and LTN. A second, major bundle produces moderate-to-heavy labeling in all ipsilateral, accessory oculomotor nuclei (nucleus of posterior commissure, interstitial nucleus of Cajal, nucleus of Darkschewitsch) and nucleus of Bechterew; some of the fibers are distributed above the caudal oculomotor complex within the supraoculomotor periaqueductal gray. A third projection is ipsilateral to the pontine and mesencephalic reticular formations, nucleus reticularis tegmenti pontis and basilar pontine complex (dorsolateral nucleus only), dorsal parts of the medial terminal accessory optic nucleus, ventral tegmental area of Tsai, and rostral interstitial nucleus of the medial longitudinal fasciculus. Lastly, there are two long descending bundles: (1) one travels within the medial longitudinal fasciculus to terminate in the dorsal cap (ipsilateral >> contralateral) and medial accessory olive (ipsilateral only) of the inferior olivary complex. (2) The second soon splits, sending axons within the ipsilateral and contralateral brachium conjunctivum and is distributed to the superior and medial vestibular nuclei. The present findings are in general agreement with the documented connections of LTN with brainstem oculomotor centers in other species. In addition, there are unique connections in marmoset monkey that may have developed to serve the more complex oculomotor behavior of nonhuman primates.

“…When these anatomical reports are considered, it is of interest that most of the FR neurons were excited by nociceptive and/or non-nociceptive stimulation. The lesions of the FH blocked nociceptive escape responses (Kaelber 1977), and the stimulation induced ocular and head rotation (Hyde and Toczek 1962;Kaelber and Smith 1979). This would suggest that the FH contributes to the motor reactions to nociception as a part of non-pyramidal circuitry (Bowsher 1975).…”
