“…The activation of the cerebellum during NEAR/FAR, as contrasted with constant fixation, converges with previously cited human lesion data, with neurophysiologic studies in paralysed anaesthetized cat preparations (Buchtel et al ., 1972; Buchtel et al ., 1973; Hultborn et al ., 1973; Ijichi et al ., 1977; Hosoba et al ., 1978; Bando et al ., 1979; Bando et al ., 1984a,b; Kato et al ., 1987; Kato et al ., 1988; Bando & Toda, 1991), with studies in non‐human primates (Ron & Robinson, 1973; Westheimer & Blair, 1973; Westheimer & Blair, 1974; Miles et al ., 1980; Judge, 1987; Gamlin & Clarke, 1995) and with human brain imaging data.…”

The purpose of this study was to identify the networks involved in the regulation of visual accommodation/vergence by contrasting the cortical functions subservient to eye-lens accommodation with those evoked by foveal fixation. Neural activity was assessed in normal volunteers by changes in rCBF measured with PET. Thirteen right-handed subjects participated in three monocular tasks: (i) resting with eyes closed; (ii) sustained foveal fixation upon a LED at 1.2 m (0.83 D); and (iii) accommodating alternately on a near (24 cm, 4.16 D) vs. a far (3.0 m, 0.33 D) LED alternately illuminated in sequential 2 s epochs. The contrast between the conditions of near/far accommodation and of constant foveal fixation revealed activation in cerebellar hemispheres and vermis; middle and inferior temporal cortex (BA 20, 21, 37); striate cortex and associative visual areas (BA 17/18). Comparison of the condition of constant fixation with the condition of resting with closed eyes indicated activation of cerebellar hemispheres and vermis; visual cortices (BA 17/18); a right hemisphere dominant network encompassing prefrontal (BA 6, 9, 47), superior parietal (BA 7), and superior temporal (BA 40) cortices; and bilateral thalamus. The contrast between the conditions of near/far accommodation with closed-eye rest reflected an incremental summation of the activations found in the previous comparisons (i.e. activations associated with constant fixation). Neural circuits activated selectively during the near/far response to blur cues over those during constant visual fixation, occupy posterior structures that include occipital visual regions, cerebellar hemispheres and vermis, and temporal cortex.

“…In cats, the motor cortex and the crown part of the parietal association cortex, which are known to receive projections from the cerebellar interpositus and lateral nuclei, project back onto the cerebellar cortex (Sasaki, 1979, for a review; Sasaki, Oka, Matsuda, Shimono & Mizuno, 1975). Recently, we have discovered projections from the same cerebellar nuclei onto the rostral half of the medial bank of the lateral suprasylvian (LS) visual area (Kawaguchi, Miyata & Kato, 1983;Kato, Kawaguchi & Miyata, 1987). We therefore set out to investigate whether this visual area also projects back onto the cerebellum, thus forming another cerebro-cerebellar loop.…”

SUMMARY1. A projection from the medial bank of the lateral suprasylvian visual area, one of the targets of the cerebello-cerebral projection, back to the cerebellar cortex was demonstrated electrophysiologically in the cat. The anatomical pathways underlying this projection were investigated using orthograde and retrograde transport ofwheatgerm-agglutinin-conjugated horseradish peroxidase (WGA-HRP).2. Responses were recorded in the cerebellar cortex on stimulation of the medial bank of the lateral suprasylvian area, and were compared with those evoked by stimulation of the motor cortex and the crown part of the parietal association cortex.3. Responses induced by stimulation of the lateral suprasylvian area were shown to consist of early mossy and late climbing fibre responses. The mossy fibre response was evoked, at a latency of 2-3 ms, predominantly in the lateral part of the contralateral cerebellar cortex (mainly, crus I, crus II, dorsal paraflocculus and paramedian lobule) and the posterior part of the vermis (mainly, lobules VII and VIII). Climbing fibre responses were elicited with the preceding mossy fibre responses and were elicited at a much longer latency than the motor cortex-induced climbing fibre response.4. The orthograde and retrograde HRP studies suggested that the mossy fibre response is mediated by the pontine grey whereas the climbing fibre response is conveyed indirectly to the inferior olive which sends the climbing fibres to the cerebellar cortex. After WGA-HRP injections into both the medial bank of the lateral suprasylvian area and the cerebellar responsive area, orthogradely labelled terminals of cortico-pontine projection fibres and retrogradely labelled pontocerebellar neurones were found in the pontine grey, where distributions of the two kinds of labelling overlapped. On the other hand, retrograde neuronal labelling alone was found in the inferior olive, implying that the climbing fibre responses evoked from the lateral suprasylvian area were relayed via indirect cortico-olivary pathways.
