Different telencephalons

Series of articles concerning the telencephalon in vertebrates. I found the articles concerning the fish telencephalon most useful. For example, J.P.C. de Bruin writes about the Telencephalon and Behavior in Teleost Fish. This article discusses various experimental results concerning the function of the fish telencephalon. Not all functions of the telencephalon are olfactory. Fish with the telencephalon removed are less likely to form schools. Fish with telencephalonic lesions have deficits in nestbuilding. Telencephalonic lesions also affect aggressive behavior and sexual behavior. G.E.Savage writes about the Fish Telencephalon and Its Relation to Learning. This article discusses various experimental results concerning the function of the fish telencephalon. Removal of the telencephalon does not cause persistent changes in the swimming or in the feeding (of detritus on the bottom of the tank which is tasted more so than smelled) of the fish. Ablated fish could in fact be trained to swim to a food holder on a screen, with good results. However, the telencephalon is essential in olfaction, as shown in experiments whereby blinded minnows could find olfactory stimuli, but ablation of the telencephalon prevented this behavior (although, discrimination with resect to gustatory stimuli still remained intact). As well, it is found that ablated goldfish would ignore a bang stimulus on the tank, and less likely to seek shelter in hidden corners of the tank. However, fear still remains in the ablated goldfish, as evident in classical conditioning experiments. In certain learning experiments, the performance of the ablated fish suggests short-term memory deficits. As well, ablated fish were much slower to learn to find their way to food through a simple maze. Since telencephalon ablation does not eliminate, but rather reduces, learned behavior, the function of the forebrain may be due to nonspecific 'arousal', although other evidence argues against the telencephalon in arousal. Perhaps the telencephalon is required to form a match for incoming data, with failure to find a match causing a complex series of responses by the reticular formation.
