“…However, the hierarchy of these cortical areas in terms of processing vestibular signals remains unknown. In particular, areas 2v, 3a, PIVC and FEFp are thought to receive short-latency vestibular information directly through the thalamus (Boisacq-Schepens and Hanus, 1972; Odkvist et al, 1974; Odkvist, 1975; Odkvist et al, 1975; Sans et al, 1976; Akbarian et al, 1992; Ebata et al, 2004). In contrast, the ventral posterior and intralaminar nuclei, vestibular relay stations in the macaque thalamus (Lang et al, 1979; Meng et al, 2007; Meng and Angelaki, 2010), are not known to send projections to VIP and MSTd.…”

“…These afferents are mediated through the lemniscal pathway and are destined to area 3a [31], Secondary fusorial endings, also called group II afferents, impinge upon most VL neurones. They reach VL through the cerebellum [34,35,41], Vestibulo-thalamic afferents were also described [49,54,55]. Exteroceptive afferents are of cutaneous, visual and auditory origin ( fig.…”

The ventrolateral (VL) and ventral anterior (VA) are the main thalamic relay for cerebellar and pallidal efferents going to the motor cortex. Four aspects of the function of these nuclei are briefly considered. (1) It is well known that these thalamic structures are not a simple relay on the way to the motor cortex, but that they have a gating function for the cerebellar afferents. The gating mechanism is active during slow-wave sleep, with deafferentation and with the use of various anesthetics. Possibly, it might play a role in the central organization of movement. (2) The organization at the unitary level of the projections between VL and motor cortex is examined and their role in the command of motor synergies through the motor cortex strongly suggested. (3) It appears that unitary activity of VL neurons is not only related to movement but also to postural changes associated with movement. (4) The sensory input to VL nucleus is briefly analyzed. The inefficacy of exteroceptive stimulation in awake animals, in contrast with the effect of the same stimulation in anesthetized preparations, is discussed.

Projections to the lateral diencephalon from the dorsal column nuclei (DCN), lateral cervical n. (LCN), and spinal cord (ST) in cats and monkeys, and from the spinal portion of the trigeminal n. (sTN) in the cat were compared using a double-orthograde labeling strategy. This strategy combines autoradiographic and degeneration tracing methods in the same animal and permits direct comparisons of the terminal labeling patterns of two different pathways in each experiment.The results suggest that the major part of the lateral diencephalon which receives input from the somatic sensory pathways in both the cat and the monkey is arranged in a core-shell fashion. The core consists of the group of nuclei which together constitute the ventrobasal complex (VB). The shell consists of a group of nuclei which together tend to surround VB nearly completely. This group includes the posterior group (PO), the ventral posteroinferior n. (VPI), and the border region between VB and the ventrolateral n. (VB-VL). In addition to the core and shell regions, two other regions in the lateral diencephalon receive input from the somatic sensory pathways. These regions are the ventromedial part of the magnocellular portion of the medial geniculate n. (MGNm) and a caudomedial portion of the zona incerta (ZI).The cytoarchitectural and hodological patterns of the core region differ from those of the shell region. In both the monkey and the cat, the core region (VB) has a relatively homogeneous cytoarchitectural appearance and is filled by dense inputs from DCN, LCN, and sTN in the cat and from DCN, LCN, and ST (and probably from sTN) in the monkey. Direct comparisons of the terminals of fibers from different pathways demonstrate that although there is some convergence on the same neurons within VB, the major tendency is for each of the inputs to form its densest terminations on different neurons. This partial segregation manifests itself in two ways. First, each pathway has its own preferred territory within VB where its terminations are the densest. Second, the terminal fields of the inputs usually have a clustered appearance which is characterized by dense patches of terminals separated by regions in which the terminations appear quite sparse. The dense patches from different pathways do not occur in relation to the same groups of neurons.In contrast, most portions of the shell region have a lower cell density than that of the core and a heterogeneous cytoarchitectonic appearance which can often be described as transitional in character between its neighboring areas. In both species, different parts of the shell region receive sparse and scattered input from those pathways which project densely and precisely to areas immediately adjacent
