| retinal ganglion cell type III | Perry (Perry) | Type III cells have small bodies but they have the largest range of dendritic field sizes (see table 1). The dendrites of this cell class branch less frequently than those of the other classes. This group of cells encompasses a slightly wider variety of dendritic morphology, than the other three classes. | partial correspondence | | There appears to be two distinct populations of cells labeled, with the majority of cells in the smaller diameter group having the diameters ranging from 10-13 micrometers, and a less populous group of larger cells having diameters of 20-25 micrometers. Although the entire cell body apperead to be stained in nearly all of the labeled cells, very little dendritic morphology can be determined from this preparation. The average cell body size would suggest that the vast majority of these cells belong to class III. | Young M.J. & Lund R.D. | Mihail Bota |

| retinal ganglion cell type I | Perry (Perry) | Type I cells have the largest cell bodies of all the classes (see table 1). The primary dendrites are generally smooth in appearance but sometimes have dendritic spines, and roughly halve their diameter at the first bifurcation (see plates 1, figures 1 and 2). The cells have 3 to 6 primary dendrites which enter the inner plexiform layer diagonally and appear to terminate in the outer part of inner plexiform layer. On many of these cells an axon could be identified and the axons were in general the thickest observed. | partial correspondence | | There appears to be two distinct populations of cells labeled, with the majority of cells in the smaller diameter group having the diameters ranging from 10-13 micrometers, and a less populous group of larger cells having diameters of 20-25 micrometers. An example of hte larger diameter group of cells is shown in Fig. 2C. This cell had an average of 22 micrometers and its size and morphology suggest it may be a class I cell, i.e., large cell body and long, straight dendrites. | Young M.J. & Lund R.D. | Mihail Bota |

| glutamate/PACAP expressing retinal ganglion cell | Hannibal et al. (Hannibal) | In the retina PACAP immunoreactivity was located to a homogeneous population of retinal ganglion cells with two to four thin, sparsely branching processes (Fig. 2A). Most processes seemed to radiatel horizontally in the ganglion cell layer towards the optic disc via the optic nerve. Other processes projected through the inner plexiform layer towards the inner nuclear layer in which they seemed to may synaptic contact (Fig. 3A). | partially corresponds | | Dense PACAP-immunoreactive retinal projections were found in the contralateral OPT while the innervation of the ipsilateral OPT was limited | Hannibal J. & Fahrenkrug J. | Mihail Bota |
