    Notes: Summary Using a new albumin prefixation technique, microtubules have been observed in close association with the nuclear pores of neurons and glia. Thus, microtubules may be involved in such phenomena as anchoring, migration or rotation of the nucleus or in chemical messenger transport between nucleus and cytoplasm. Microtubules are also seen running close to the coated pits of dendrites. The implications are discussed.

    Notes: Summary The influence that thyroid hormones have on the development of the cerebellar cortex is well known. Their absence in adults leads to important functional changes probably related to abnormalities in nerve terminal activity, although no morphological alterations have hitherto been described. Using ultrastructural morphometric methods, we have studied the effects of thyroidectomy on the cerebellar cortex mossy fiber terminals of adult rats with different survival periods. No significant changes in the volume and surface area of these terminals were found. The numbers of synaptic vesicles in groups 7, 15 and 30 days after thyroidectomy were significantly greater than in controls. A significant increase in coated pit formation was found when thyroidectomized groups were compared with controls. This increase is due to the lack of thyroxin since it can be counteracted by thyroxin administration. Whether this increased coated pit formation is a membrane retrieval mechanism or is related to the uptake of extracellular molecules remains to be determined.
