Abstract

The most conserved part of the vertebrate dopaminergic system is the orthopedia ( otp )-expressing diencephalic neuronal population that constitutes the dopaminergic diencephalospinal tract (DDT). Although studies in the neonatal murine spinal cord in vitro suggest an early locomotor role of the DDT, the function of the DDT in developing vertebrates in vivo remains unknown. Here, we investigated the role of the DDT in the locomotor development of zebrafish larvae. To assess the development of the behavioral and neural locomotor pattern, we used high-throughput video tracking in combination with peripheral nerve recordings. We found a behavioral and neural correspondence in the developmental switch from an immature to mature locomotor pattern. Blocking endogenous dopamine receptor 4 (D 4 R) signaling in vivo either before or after the developmental switch prevented or reversed the switch, respectively. Spinal transections of post-switch larvae reestablished the immature locomotor pattern, which was rescued to a mature-like pattern via spinal D 4 R agonism. Selective chemogenetic ablation of otp b ( otpb ) neurons that contribute to the DDT perpetuated the immature locomotor pattern in vivo . This phenotype was recapitulated by diencephalic transections that removed the dopaminergic otpb population and was rescued to a mature-like locomotor pattern by D 4 R agonism. We conclude that the dopaminergic otpb population, via the DDT, is responsible for spinal D 4 R signaling to mediate the developmental switch to the mature locomotor pattern of zebrafish. These results, integrated with the mammalian literature, suggest that the DDT represents an evolutionarily conserved neuromodulatory system that is necessary for normal vertebrate locomotor development.

  • Blocking D4 dopamine receptors at 3 dpf prevents the transition from burst to beat-and-glide swimming.

    “Blocking D4 dopamine receptors at 3 dpf prevents the transition from burst to beat-and-glide swimming (Lambert et al., 2012), suggesting that dopamine from supraspinal sources plays a role in setting the beat-and-glide phenotype by shortening swimming episode duration.”

    In Results, under “Blocking endogenous D4 receptor signaling prevents maturation of the locomotor pattern” (page unavailable), the authors report that D4 antagonism during 3–4 dpf prevented the normal shift to short swimming episodes at 4 dpf. The Introduction describes the developmental change as a shift from long to short episodes of beat-and-glide swimming, not a transition from burst swimming to beat-and-glide swimming. (LLM, conf=0.85)

  • Beat-and-glide swimming can be produced in isolated larval zebrafish spinal cord preparations by NMDA application or by optogenetic stimulation of excitatory spinal neurons.

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.
