章节摘录

  These authors find a preponderance of LGNdcells preferring horizontal and vertical stimuli and suggest that cortical afferents areinvolved in the generation of LGNd orientation sensitivity (see also Daniels et al.,1977). Other authors report that the orientation biases of LGNd relay cells strictlyreflect those of their retinal afferents (Soodak et al., 1987). These authors favorthe idea that the orientation sensitivity of LGNd relay cells originates in the retinaand reflects the anatomically generated (Leventhal and Schall, 1983), linear,orientation-sensitive response (Levick and Thibos, 1982) of the retinal ganglioncells providing their afferents.  The present study is arguably the most exhaustive to date. We believe thatsome of the disagreements described above are more apparent than real andmay have resulted because previous studies included only relatively smallsamples of cells and, thus, differences in laminar location, eccentricity, polarangle, cell type could not be adequately controlled. For example, our findingsthat relay cells preferring different orientations are clustered and that radialand tangential orientations are overrepresented makes claims regarding theoverall distribution of preferred orientations based upon small samples of cellsespecially hard to interpret. For example, if cells are recorded mainly fromregions of the LGNd subserving the horizontal and vertical meridians, then anapparent preponderance of these orientations should result. Our finding thatthe radial bias is strongest in regions of the LGNd subserving the horizontalmeridian further complicates matters.  It should be noted that our results are generally consistent with the ideathat the orientation-sensitive response of most LGNd cells is a direct reflectionof their retinal inputs (Soodak et al., 1987). Evidence for this stems from ourfinding that the overall distributions of the orientation biases of LGNd cells aresimilar to those reported previously for retinal ganglion cells (Levick andThibos, 1982; Leventhal and Schall, 1983) and that the receptive fields ofmost of the cells we studied were consistent with the model proposed by Soodaket al. (1987). Our results do not support the idea (Vidyasagar and Urbas,1982; Vidyasagar, 1984) that LGNd relay cells are much more orientationsensitive than their retinal inputs. However, it should be noted that some ofthe most orientation-sensitive cells we studied exhibited "butterfly-shaped"orientation tuning curves even at relatively low spatial frequencies. A number
