Effects of olfactory bulb ablation on cardiac and ventilatory arousal responses and their habituation in the goldfish Carassius auratus.
The effects of olfactory bulb ablation on the cardiac and ventilatory arousal responses to the onset of illumination and habituation of these responses were investigated in goldfish. Bulbectomy did not effect the magnitude of response on novel stimulus presentation. Normal, sham operated, and olfactory bulb-ablated animals showed similar rates of habituation. These results suggest that deficits in feeding and sexual behavior in goldfish are due to the loss of specific olfactory influences on lower brain centers and not due to a decrease in general responsiveness.
