Maya-Prana: Metabolic Plasticity Budget for Continual Learning in Affective Spiking Neural Networks

Without Prana, nothing moves, nothing learns, nothing grows. We present Maya-Prana, the ninth and final paper in the Maya Research Series, which completes the Antahkarana by introducing Prana (प्राण) as a metabolic plasticity budget governing how much learning the system can sustain per unit time. Prana is modelled on the Astrocyte-Neuron Lactate Shuttle (ANLS): astrocytes supply lactate fuel to active neurons during sustained synaptic activity; when metabolic demand exceeds supply, plasticity degrades. In Maya-Prana, Prana is a scalar budget that depletes under gradient load proportional to gradient magnitude and neural activity, recovers during low-activity batches modulated by Vairagya, partially restores at task boundaries (sleep analogue), and gates the effective learning rate per batch: effectiveₗr = baseₗr × prana × (0. 5 + buddhi × 0. 5). The biological calibration (PRANACOSTRATE=0. 002315, the ORCID magic number) produces a system in which Prana maintains full budget (1. 0000) throughout all 10 tasks — consistent with the ANLS literature, which confirms that the astrocytic metabolic supply does not fail under standard cognitive load. A six-condition ablation on Split-CIFAR-100 (10 tasks, seed=42) establishes four findings. Condition C (fixed Prana=1. 0) and Condition D (canonical) are near-equivalent — AA=12. 02% versus 12. 72% — confirming Prana resilience as the primary result. Condition B (Prana without full Antahkarana) produces the worst result (AA=10. 33%, Pruned=91. 85%), proving that Prana cannot substitute for the integrated Antahkarana. Condition E (PRANACOSTRATE=0. 008, 3. 5× canonical) still never depletes Prana, confirming ANLS robustness under accelerated metabolic demand. Condition F (no Buddhi modulation, fixed EffLR=0. 0075) produces the unexpected best result: AA=13. 68%, BWT=−51. 20%, Pruned=46. 93%, revealing that the Buddhi warm-up schedule penalises early task consolidation — an honest finding about the Buddhi-Prana interaction term, reported as discovered. We confirm, for the ninth consecutive paper, that Bhaya quiescence under replay is a series-level constant — the Bhaya Quiescence Law. Buddhi's S-curve consolidation gate is confirmed as architecturally deterministic across all six conditions. An embodied demonstration of the full Antahkarana running on a PiCar-X robotic platform with Raspberry Pi 5 is available on YouTube (see Section 5. 9).
