Hidden Target Navigation Task with Dopamine Photometry Recordings in Mice

Data from a neuroscience experiment on mouse navigation and reward collection, with simultaneous fiber photometry recordings of dopamine activity in the nucleus accumbens core. The dataset, created by Josh Dudman, is 655.7 MB in size and was last updated in May 2026. It includes continuous signals for location and dopamine activity, as well as discrete event timestamps for actions like reward triggers and licks.

Use Cases

• Modeling dopamine signal dynamics during spatial navigation based on continuous 'nac' photometry data.
• Analyzing the timing of reward-seeking behaviors like 'rewCollect' and 'lick' events relative to animal location.
• Investigating the effect of reward size ('rewSize') and optogenetic stimulation on behavioral and neural correlates.

Strengths

• Includes simultaneous behavioral (X, Y location) and neural (dopamine activity) recordings, enabling joint analysis.
• Contains discrete event timestamps for specific actions like 'rewTrigger' and 'firstLick'.
• Data is structured by experimental group (e.g., different reward sizes, optogenetic stimulation).

Limitations

• Column-level documentation is absent; field semantics must be inferred from the description after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• Data is stored in the proprietary MAT format, requiring specific software (e.g., MATLAB) for access.
