A type of apparently axonless granule cell in the cat auditory cortex

In the auditory areas (A I, A II and the posterior ectosylvian gyrus) of the cat, unusually small granule cells apparently lacking an axon are described. They are exclusively located in layer 2/3 and sometimes impregnate in groups of 4 or 5, being probably quite frequent. Some morphological differences between granule cells of young and adult cats are noted.
