Abstract

VISIBLE local modification of the cellular nuclear membrane is usually considered a phenomenon associated with the discharge of nucleic acid from nucleus to cytoplasm. Barr and Bertram1 have noted thin ‘nuclear caps’ in nerve cells concomitant with the reproduction of Nissl substance during recovery from antidromic stimulation. Such ‘nuclear caps’ appear as distinctive dense or thickened local areas of the nuclear membrane which stain with basic dyes, give positive histochemical reactions for nucleic acid, and absorb heavily at 2600 A. with ultra-violet light methods. Electron studies also indicate that the membrane may be thickened and modified during regeneration after axonic severance2.
