Published Workflows
Objective: Demonstrate functional regionalization of cerebellar output in vivo by mapping Purkinje neuron efferent circuits, relating them to regional activity during behavior, and causally testing selected regions with optogenetics.
Why it works: The workflow combines circuit mapping, observation of regional activity patterns during behavior, and causal perturbation of selected regions, so anatomical output regionalization can be linked to physiological activity and behavioral function in vivo.

Stages
- 1.Transneuronal mapping of Purkinje efferent circuits(functional_characterization)
This stage provides in vivo evidence for regionalization of cerebellar cortical output by identifying efferent circuits of Purkinje neurons.
Selection: Identification of efferent circuits from zebrafish Purkinje neurons
- 2.Behavior-linked observation of regional Purkinje activity patterns(secondary_characterization)
This stage links mapped circuits to distinct regional activity patterns in freely behaving larvae, strengthening the functional interpretation of regionalized output.
Selection: Correspondence between identified circuits and distinct regionalized Purkinje cell activity patterns during cerebellar-dependent behaviors
- 3.Optogenetic confirmation during behavior(confirmatory_validation)
This stage tests whether selected Purkinje cell regions causally contribute to behavior and lateralized output, confirming the functional significance of the regionalization inferred from mapping and activity patterns.
Selection: Causal confirmation of functional regionalization and contribution to behavior control

The abstract indicates that the approach is genetically encoded and applied in zebrafish Purkinje neurons in vivo.; requires genetic encoding in the studied neurons
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.

Optogenetic interrogation of selected Purkinje cell regions during behavior confirmed functional regionalization of Purkinje cell efferents and revealed contributions to behavior control and lateralized behavioral output.
Furthermore, optogenetic interrogation of selected Purkinje cell regions during animal behavior confirms the functional regionalization of Purkinje cell efferents and reveals their contribution to behavior control as well as their function in controlling lateralized behavioral output.
