OF CORNEAL AND 6ILL REGION
STIMULA TION OF GILL REGION
FIG. 3. Diagram illustrating the mode of operation (upper row) and the functional result in larval period (middle row) and after metamorphosis (lower row).
First column: Replacement of the trigeminal ganglion by a vagus ganglion. Gill
reflex can be evoked from the cornea in larval period; the corneal reflex is present
both from the cornea and from the gill region after metamorphosis. Second column:
Replacement of the vagus ganglion by a trigeminal ganglion. Gill reflex can be
evoked both from the gill region and from the cornea in larval period; only normal
corneal reflex is experienced after metamorphosis. Third column: Orthotopic transplantation of trigeminal ganglia serves as control. Normal reflexes are present during
all stages of development. (By courtesy of the Publishing House of the Hungarian
