Source: Muto, A., et al. Ablation of a Neuronal Population Using a Two-photon Laser and Its Assessment Using Calcium Imaging and Behavioral Recording in Zebrafish Larvae. J. Vis. Exp. (2018) In this video, a two-photon laser ablation procedure is demonstrated, enabling the selective destruction of fluorescent neurons in agarose-immobilized zebrafish larvae. High-resolution imaging before and after the procedure confirms efficient neuronal damage, as observed by the absence of fluorescence.

We describe how to use laser capture microdissection (LCM) to obtain enriched populations of hippocampal neurons or single neurons from frozen sections of the injured rat brain for subsequent gene expression analysis using quantitative real time PCR and/or whole-genome microarrays.
FAQs
Cell-type-specific genetic or viral strategies direct an ablation mechanism toward a defined neuronal group rather than the surrounding circuit. These strategies can activate a cytotoxic effector, a toxin, or a programmed cell-death pathway in the targeted cells. Selectivity allows researchers to relate later changes in circuit function or behavior to the population that was removed.
Spatial and temporal control determines where and when neuronal loss occurs. Restricting the intervention to a selected neural region helps distinguish local population functions from effects caused by broader damage, while controlling timing permits analysis of circuit roles under defined experimental conditions. These controls strengthen interpretation of changes in activity, connectivity, or behavior after ablation.
Removing a defined neuronal population provides a direct test of whether that population is necessary for a circuit function or behavior. Researchers can compare neural and behavioral outcomes before and after the controlled loss, then associate resulting changes with the targeted cells. This causal approach differs from merely observing activity correlations within an intact circuit.
Post-ablation analysis can examine neural activity, connectivity, and behavior as separate but complementary outcomes. Activity measurements indicate how circuit signaling changes, connectivity analysis reveals alterations in network relationships, and behavioral tests show whether those changes affect function. Considering these outcomes together helps connect cellular removal with circuit-level and organism-level consequences.
A typical study first identifies the neuronal population and applies a cell-type-specific genetic or viral strategy. The selected cytotoxic effector, toxin, or programmed cell-death pathway is then activated under controlled spatial or temporal conditions. Researchers subsequently assess neural activity, connectivity, and behavior to determine the functional consequences of removing that population.
This approach is useful when researchers need to test the contribution of a defined neuronal group to circuit function, behavior, or disease-related processes. It can clarify population roles in neurodegeneration, epilepsy, and brain injury, while also helping evaluate whether particular neuronal populations could represent targets for therapeutic intervention.
