Fig. 4. A sen~ischeniatic representation of the synaptic apparatus found in
Manthner’s cell in the goldfish. The data of Beccari (1907), Bartelmez (1915), and
Rodian (1937) indicate the following general segregation of synapses on the cell
surface (the total number of endings is much larger than shown; for actual counts,
see Bodian, 1937 ). The lateral dendrite. ( 1 ) Distal portion-club
endings of direct
vestibular root fibers ( sacculus ). ( 2 ) Proximal portion-end
bulbs of collaterals
of crossed vestibular root fibers; secondary vestibular fibers( ? ). The ventral dendrite.
( 1 ) End bulbs from fibers of ventral acoustic nucleus. ( 2 ) End bulbs of cerebelloreticular fibers. ( 3 ) End hulhs of crossed and uncrossed tectal fibers. (4) End bulbs
of fibers from nucleus princeps trigeniini. ( 5 ) End bulbs of fibers in medial longitudinal fasciculns. The perikaryon. ( 1) Small end bulbs on axon hillock derived
froin spiral fibers ( sl) ) of the medial longitudinal fasciculns [from mesencephalic
nucleus of the medial longitudinal fasciculus ( ?)I. ( 2 ) Knob endings of collaterals
