TL;DR: It was found that the rate of cellulifugal transport of CA in the sciatic nerve of this species is 7 mm per 24 hr and both CA and granulated vesicles were found to accumulate almost linearly in dammed up portions of nerves ligated for zero, 24, 48 and 72 hr.
Abstract: Biochemical data have been correlated with fine structural features to study CA transport in adrenergic fibers of the toad. It was found that the rate of cellulifugal transport of CA in the sciatic nerve of this species is 7 mm per 24 hr. Both CA and granulated vesicles were found to accumulate almost linearly in dammed up portions of nerves ligated for zero, 24, 48 and 72 hr. On the basis of the electron microscopic observations it is postulated that the granulated vesicles (CA storage particles) originate from membrane-bounded canaliculi and assumed, therefore, that CA are transported down the toad adrenergic axons within the lumina of the smooth endoplasmic reticulum.

TL;DR: In the present experiment potential changes were recorded at the same time from two different layers, that is, the surface of the receptor layer and the inner plexiform layer, and compared with each other.
Abstract: Recent development of microelectrode technique has made possible a recording of a potential localized within a small part of tissue. Applying this technique to the retina, Tomita1)2) recorded potentials from various depths of the retina and called them \"intra-retinal electroretinogram\" (EIRG) . Svaetichin3), Brindley4)15) and other workers6)7)8) also have tried to analyse retinal response by similar methods. But it has remained to be explored how these potentials of different layers are related with one another. In the present experiment potential changes were recorded at the same time from two different layers, that is, the surface of the receptor layer and the inner plexiform layer, and compared with each other.
