Deficits in acquisition of spatial learning after dorsomedial telencephalon lesions in goldfish
Spatial learning de¢cits after the development of dorsomedial telencephalon lesions in gold¢sh
TLDR
Results suggest that dorsomedial lesions selectively caused impairment in the retention of spatial learning in gold¢sh.
Telencephalon and geometric space in goldfish
TLDR
The results indicate that lesions to the lateral pallium of goldfish, like hippocampal lesions in mammals and birds, selectively impair the encoding of geometric spatial information of environmental space, and suggest that the forebrain structures of teleost fish that are neuroanatomically equivalent to the mammalian and avian hippocampus also share a central role in supporting spatial cognition.
Involvement of the telencephalon in spaced-trial avoidance learning in the goldfish (Carassius auratus)
The role of telencephalic NMDA receptors in avoidance learning in goldfish (Carassius auratus).
TLDR
The present study investigated the amnestic effects of microinjections of the NMDA receptor antagonist D(-)-2-amino-5-phosphonopentanoic acid to the goldfish telencephalon on avoidance conditioning and found that D-AP5 impaired avoidance learning through its interaction with telENCEphalic NMDA receptors in goldfish.
Stress and fear responses in the teleost pallium
Stimulation of the lateral division of the dorsal telencephalon induces synaptic plasticity in the medial division of adult zebrafish
Avoidance conditioning in bamboo sharks (Chiloscyllium griseum and C. punctatum): behavioral and neuroanatomical aspects
TLDR
This study investigated whether elasmobranchs (Chiloscyllium griseum and C. punctatum) can be conditioned in an aversive classical conditioning paradigm to reveal if the neural substrates governing avoidance behavior or tasks learned in a classical conditioned paradigm are located within the telencephalon, as has been shown for teleosts such as goldfish.
Organization of the gymnotiform fish pallium in relation to learning and memory: II. Extrinsic connections
TLDR
The results allow us to hypothesize that a functional distinction between electrocommunication vs. electrolocation is maintained within the input and output pathways of the gymnotiform pallium, and hypothesizes that cells responsive to communication signals do not converge onto the same targets in the preglomerular complex as cellsresponsive to moving objects.
The role of telencephalic NO and cGMP in avoidance conditioning in goldfish (Carassius auratus).
TLDR
Results showed that L-NAME and LY-83583 produced significant anterograde and retrograde amnesia at doses that did not impair performance processes, and the drugs produced more severe retrograde than anterOGrade amnesia, which suggests that the NMDA receptors are involved in learning or the process that is completed during training, whereas the NO and cGMP are involved during training.

Spatial learning and memory deficits after telencephalic ablation in goldfish trained in place and turn maze procedures.
TLDR
The results suggest that the fish telencephalon plays a crucial role in complex place learning, and that ablation exclusively impaired performance in animals using place strategies.
Dissociation of place and cue learning by telencephalic ablation in goldfish.
TLDR
The results offer additional evidence that place and cue learning in fish are subserved by different neural substrates and that the telencephalon of the teleost fish, or some unspecified structure within it, is important for spatial learning and memory in a manner similar to the hippocampus of mammals and birds.

TLDR
The effects observed are the opposite of those obtained after complete or unilateral telencephalic ablation in teleosts and suggest the existence of antagonic telencecephalic systems playing a modulatory role in arousal control.

Different types of fear-conditioned behaviour mediated by separate nuclei within amygdala
TLDR
This work shows that distinct neural systems involving separate amygdaloid nuclei mediate different types of conditioned fear behaviour, and suggests that theories of amygdala function should take into account the roles of discrete amygdala subsystems in controlling different components of integrated emotional responses.
