Cells in the cat's dorsal lateral geniculate nucleus (LGN) were studied by presentation of visual stimuli and also by simultaneous recording of their ganglion cell inputs in the retina. This paper describes receptive-field properties and a new system of classification for LGN X-cells that appear to receive essentially only one excitatory retinal input. These X-cells were of two distinct classes. The visual responses of one class of cell (XS, single) replicated the basic form of the responses of a retinal X-cell. The other class of cell (XL, lagged) had responses with two remarkable features: their firing lagged 40-80 ms behind that of XS-cells or ganglion cells at response onset, and they fired anomalously at times when XS-cells or ganglion cells would not be firing. Thus, for a flashing spot, XL-cells were inhibited from firing after stimulus onset, during the time when XS-cells or retinal X-cells had an initial transient peak in firing; XL-cells generally had an anomalous peak in firing after stimulus offset, after XS-cells or retinal X-cells had stopped firing. For a moving bar, XS-cells or retinal X-cells responded primarily while the bar was in the receptive-field center, whereas most of a typical XL-cell's response occurred after the bar had left the receptive-field center. The latencies of various features in the visual responses were analyzed. For several visual response latencies, the distribution was clearly bimodal, thus objectively demonstrating the existence of two cell classes. Using only the latencies from spot and bar responses, over 90% of these single-input cells could be reliably identified as belonging to one of the two classes. The remaining cells (7 of 128) were intermediate between the two classes in some but not all respects; because they had some properties in common, these cells were kept in a separate group (XPL, partially lagged). The axons of both XS- and XL-cells could be antidromically activated from visual cortex. Cortical latencies were typically 0.7-2.0 ms for XS-cells but much longer, typically 2.4-5.0 ms, for XL-cells. It is possible that XL-cells have not previously been recognized as a separate class because cells with such long latencies have been recorded infrequently in the past. Responses to central flashing spots were more transient than those of retinal X-cells for most XS-cells and more sustained for most XL-cells.(ABSTRACT TRUNCATED AT 400 WORDS)

White, Andrew J. R., Heath D. Wilder, Ann K. Goodchild, Ann Jervie Sefton, and Paul R. Martin. Segregation of receptive field properties in the lateral geniculate nucleus of a New-World monkey, the marmoset Callithrix jacchus. J. Neurophysiol. 80: 2063–2076, 1998. The lateral geniculate nucleus (LGN) in humans and Old-World monkeys is dominated by the representation of the fovea in the parvocellular (PC) layers, and most PC cells in the foveal representation have red–green cone opponent receptive field properties. It is not known whether these features are both unique to trichromatic primates. Here we measured receptive field properties and the visuotopic organization of cells in the LGN of a New-World monkey, the marmoset Callithrix jacchus. The marmoset displays a polymorphism of cone opsins in the medium-long wavelength (ML) range, which allows the LGN of dichromatic (“red–green color blind”) and trichromatic individuals to be compared. Furthermore, the koniocellular–interlaminar layers are segregated from the main PC layers in marmoset, allowing the functional role of this subdivision of the LGN to be assessed. We show that the representation of the visual field in the LGN is quantitatively similar in dichromatic and trichromatic marmosets and is similar to that reported for macaque; the vast majority of LGN volume is devoted to the central visual field. on- and off-type responses are partially segregated in the PC layers so that on responses are more commonly encountered near the external border of each layer. The red–green (ML) opponent cells in trichromatic animals were all located in the PC layers, and their receptive fields were within 16° of the fovea. The koniocellular zone between the PC and magnocellular layers contained cells that receive excitatory input from short wavelength sensitive cones (“blue-on cells”) as well as other nonopponent cells. These results suggest that the basic organization of the LGN is common to dichromatic and trichromatic primates and provide further evidence that ML and SWS opponent signals are carried in distinct subdivisions of the retinogeniculocortical pathway.
