metric,what_to_report,comparison_note
Task performance,"Accuracy, reward, error or task-specific score",Compare against a strong electronic baseline under matched conditions
Learning speed,"Samples, episodes or wall-clock time to target performance",Report both biological adaptation and digital readout training
Data efficiency,Training examples or interactions required,Separate pretraining and online adaptation
Stability,Performance drift across hours or days,"Show mean, variance and failure modes"
Culture-to-culture variance,Spread across independent biological preparations,"Report biological n, not only repeated trials on one culture"
Retention,Performance after a defined rest interval,"State whether readout weights, stimulation protocol or biological state are retained"
I/O bandwidth,Independent input and output channels plus update rate,"Include effective usable channels, not electrode count alone"
Whole-system energy,Culture support + stimulation + recording + digital compute,Measure the full experimental stack at the wall where possible
Preparation cost,"Cell culture, maturation, consumables and specialist labour",State amortisation assumptions
Lifetime,Useful operating period at specified performance,Distinguish tissue viability from computational usefulness
Replication,Independent repeats and external laboratory replication,"Label company-only, preprint and peer-reviewed evidence separately"
Recoverability,"Ability to restart, recalibrate or transfer function after failure",Record whether learned state can be copied or reconstructed
