Deficits in foraging behavior after telencephalon ablation in the goldfish (Carassius auratus)

Foraging behavior was examined in normal, sham-operated, and forebrainablated goldfish. The pattern of learning, long-term memory, and relearning capabilities were tested. Olfaction was ruled out as the directing mechanism involved with foraging in this species. Although forebrain-ablated fish demonstrated arousal deficits, arousal alone was not sufficient to explain the deficits in foraging behavior in ablated fish. Long-term memory deficits were found in the ablated fish. Learning patterns also differed between the forebrainless fish and the normal and sham-operated fish.
