[Afferent connections of columns of area 17 and 18 of the cerebral cortex formed by neurons of dorsal lateral geniculate bodies in cats].
Horseradish peroxidase (HRP) was injected microiontophoretically into nine single area 17 columns and six area 18 columns of the cat's cerebral cortex. Within the dorsal lateral geniculate nucleus most of the labelled cells were found in the laminae A. The ratio of HRP-labelled cells in lamina A to those in lamina Al (A/A1) was estimated. After injection of HRP in area 17 columns this ratio varied from 0.5 to 2.5, while after HRP injection into area 18 columns it varied from 0.2 to 0.9. These data may indicate that in the areas studied contain the columns that receive afferents from both ipsilateral and contralateral eyes.
