The retina of Pecten maximus is divided into two light sensitive layers forming the distal and proximal retinae. The cells from these layers have different electrophysiological responses, the distal cells giving primary “off” responses, and the proximal cells giving “on” responses. The receptor surfaces of the distal retinal cells are formed from lamellae(More)
1. The external plexiform layer of the retina was examined in the frog (Rana temporaria), the chick (Gallus domesticus), the tortoise (Testudo graeca), and the rabbit, guinea pig, cat and bush baby in order to compare differences of morphology and concentration per unit area between rod vesicles and cone vesicles. 2. Rod synaptic vesicles were observed to(More)
Sheets of mucosal epithelial cells were released from guinea pig small intestine after incubation with ethylenediaminetetraacetate. Cells in sheets retained their columnar shape for 24 hr at room temperature, and exclusion of nigrosine suggested they had intact plasma membranes. When sheets were disaggregated individual cells had normal morphology for at(More)
We have used suspensions of isolated cells to study the metabolism of the mucosal epithelium and to compare its activity with that of other tissues in the intestinal wall of guinea pig. Only 4% of the total glycolytic activity of the intestinal wall could be attributed to the mucosal epithelium. In contrast, about 76% of the activity was located in the(More)
