    Notes: Summary The distribution of thalamic cells projecting to the head of the caudate and their interrelations with thalamo-cortical cells were studied in the cat with different combinations of fluorescent tracers. Injections in the head of the caudate were combined with the injections in the pericruciate, proreal, suprasylvian, anterior cingulate, occipital and ectosylvian cortices. The following results were obtained: (i) Injections in the head of the caudate resulted in retrograde labeling of thalamic cells medially and laterally to the anteromedial (AM) nucleus, and in the medioventral part of the ventral anterior (VA) nucleus. Further, labeled cells were distributed throughout the anterior intralaminar central medial (CeM), paracentral (Pc) and central lateral (CL) nuclei, and the posterior intralaminar center median-parafascicular complex (CM-Pf). Labeled cells were mainly grouped in the mediodorsal parts of the anterior intralaminar nuclei; they were also found in the more dorsal part of the mediodorsal (MD) nucleus, ventral to the thalamic paraventricular (Pv) nucleus and to the habenular complex, (ii) Thalamo-cortical and thalamo-caudate cells overlapped in the medial part of the VA; in the anterior intralaminar nuclei they were either intermingled or were distributed in separate clusters or longitudinal bands. The two cell populations also overlapped in the posterior intralaminar complex. The greatest overlap occurred with the thalamic cell population projecting to the pericruciate cortex. (iii) Thalamic cells bifurcating to the head of the caudate and to the pericruciate cortex were found lateral to the AM, within the VA, and throughout the anterior intralaminar nuclei, especially in the CeM and in the posterior part of the CL; a few branched cells were also found in the CM. Thalamic cells bifurcating to caudate and anterior suprasylvian cortex were also found in the VA. Very few cells (scattered in the anterior thalamus lateral to the AM, as well as in the CeM, Pc and CL) were found to bifurcate to the head of the caudate and the other cortical fields here examined.

    Brain stem neurons projecting to neocortex: A HRP study in the cat (1978)

    Notes: Summary The cortical projections of the brain stem were investigated in detail in the cat by means of the horseradish peroxidase (HRP) retrograde axonal transport. Most of the cells providing ascending fibers to the neocortex were located in the pons (locus coeruleus and related structures, central gray substance, dorsal tegmental nucleus, raphe nuclei, reticular nuclei); labeled neurons were also identified in the mesencephalon, mainly in the periaqueductal gray and in the nucleus linearis rostralis. These projections, and particularly the pontine fibers, were diffusely distributed throughout the cerebral cortex. The results are compared with the data previously obtained by the use of anterograde and retrograde tracing techniques.

    Efferent fibers from the motor cortex terminate bilaterally in the thalamus of rats and cats (1985)

    Notes: Summary The anterograde transport of lectin-conjugated horseradish peroxidase (WGA-HRP) was here employed in order to visualize crossed cortico-thalamic efferents of the motor cortex in rats and cats. After WGA-HRP cortical injections in the rat retrogradely labeled cells were observed in the ipsilateral thalamus, and heavy anterograde labeling was observed both in the ipsi-and contralateral thalamus. The contralateral anterograde labeling was less intense than the ipsilateral one and it was distributed in the anterior intralaminar structures, in the parafascicular nucleus, in the ventromedial, ventrolateral and ventrobasal nuclei and in the posterior complex, symmetrically to the labeling observed on the ipsilateral side. Further experiments were made in the rat in order to ascertain that the bilateral anterograde labeling in the thalamus derived unilaterally from the cortex. To this purpose, kainic acid was injected unilaterally either into the frontal cortex or into the thalamus, and WGA-HRP was later injected on the same side in the frontal cortex. Moreover, WGA-HRP was injected into the frontal cortex after splitting of the corpus callosum. The results obtained in these experiments confirmed that cortical neurons projected bilaterally upon the thalamus. Further, these experiments indicated that at least the majority of the contralateral fronto-thalamic fibers crossed the midline in the thalamic massa intermedia. WGA-HRP injections into the pericruciate cortex in the cat confirmed the presence of anterogradely labeled terminals in the contralateral anterior and posterior intralaminar, ventral anterior, ventromedial and ventrolateral nuclei. The labeling was in all cases heavier in the intralaminar nuclei than in the other structures, but it was less intense than that observed in the rat. The labeling in the contralateral principal nuclei was heavier in one case in which the injection area diffused into the proreal cortex than in the other cats. Thus, the present results indicate that frontal efferents terminate more densely in the rat's than in the cat's contralateral thalamus. In the latter species frontal fibers are mainly distributed upon the contralateral intralaminar nuclei, whereas in the rat frontal efferents are also heavily distributed upon the ventral nuclear complex.

    Notes: Summary The effects of dopexamine on the renal circulation have been examined to show whether any augmentation of renal blood flow (RBF) was secondary to the effect of the drug on cardiac output (CO) or whether it had any additional direct renal vasodilator activity. Eight male patients with mild to moderate hypertension, who were undergoing renal vein catheterization for renin estimation, were studied. Dose related increments in RBF (baseline (B)=504 ml·min−1; after treatment (D)=605 ml·min−1), CO (B=5.9 l·min−1; D=6.7 l·min−1), heart rate (B=77 beats/min; D=100 beats/min) and systolic blood pressure (B=143 mmHg; D=166 mmHg) were observed on administration of dopexamine 3 µg·kg−1·min−1, with insignificant changes in diastolic blood pressure (B=84.4 mmHg; D=90 mmHg) and total peripheral resistance (B=17.85; D=17.25 Units). There was a slight but significant reduction in renal vascular resistance (B=20.59, D=18.75). The ratio of RBF to CO (%) confirmed that the increase in RBF due to dopexamine hydrochloride was greater that attributable to the increase in CO or perfusion pressure alone (RBF/CO B=8.5%, D=9%), consistent with selective renal vasodilation. The fall in renin activity and lack of systemic vasodilatation suggest that this was a DA1-receptor mediated effect.

    Chemical Compartmentation and Relationships between Calcium-binding Protein Immunoreactivity and Layer-specific Cortical and Caudate-projecting Cells in the Anterior Intralaminar Nuclei of the Cat (1994)

    Notes: Neurons projecting to the parietal cortex or striatum and neurons showing immunoreactivity for the calcium-binding proteins parvalbumin and 28KD-calbindin were examined in the anterior intralaminar nuclei (IL) of the cat. Retrograde tracing from deep or superficial parietal cortical layers or from the caudate nucleus was coupled with immunohistochemistry to determine which of these proteins were expressed in the projection neurons. It was found that IL neurons project to deep as well as to superficial layers of the parietal cortex, that IL-cortical neurons could be differentiated into two populations according to their cortical projection pattern and their soma size, and that IL neurons projecting to the parietal cortex or to the striatum express 28KD calbindin immunoreactivity but not parvalbumin immunoreactivity. The distribution of immunoreactivity to 28KD calbindin and parvalbumin in the neuropil showed a consistent complementary distribution pattern in the IL. The compartments based on differential parvalbumin and 28KD calbindin expression may indicate the presence of functionally segregated units in IL.
