Motor responses to localized electrical stimulation of the tectum in the freshwater perch (perca fluviatilis)
Abstract
The results of localized electrical stimulation of the teleostean tectum indicate the presence within each tectal lobe of separate motor areas mediating ipsilateral turning, contralateral turning, and rolling movements. Stimulation of caudal regions produced larger turning circles than stimulation of rostral sites. Both these sets of observations conflict with the retinotopic map. Stimulation sites connected with turning and rolling movements were mostly located in the upper layer of the tectum. Other kinds of movement including aggressive behaviour, escape movements, head dipping, and forward swimming were obtained by stimulating the deeper tectal sites and subtectal areas. These results suggest that the tectum may be differentiated into areas with specific motor functions and afferent connections. This has important consequences for studies on optic nerve regeneration and neuronal specificity.

Electrical stimulation of the intermediate and deep layers of the optic tectum of goldfish triggers orienting responses consisting of coordinated eye and fin movements, axial musculature adjustments, and locomotion behavior that closely resemble natural orienting responses.

The optic tectum of teleosts receives sensory information mainly from multiple sensory modalities to form real-time representations of the animal surrounding, to identify significant stimuli, like preys or predators, and to trigger sensory guided responses.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
