In Winkler's laboratory, Ferraro studied the nervous system of a dog whose pallium had been removed four years previously by Prof. Zeliony in Pavlov's laboratory. Pavlov reported the physiologic findings before the Congress of Edinburgh in 1923.

Of the neopallium there remained only an insignificant portion of the gyrus fornicatus, medially a part of the area prelimbica, area limbica anterior, and a part of the area retrolimbica. No trace of the visual cortex remained; of the paleopallium, a trace of the white matter of the lobus olfactorius posterior in its caudal portion. On the left side, the olfactory bulb was no longer in communication with the brain. On the right side, the anterior and posterior olfactory lobes were spared to a great extent. The lobus piriformis was fairly well preserved. The lobus parolifactorius was unharmed on either side. Of the archipallium, the cornu ammonis was notably damaged and partially extirpated.
