Résumé	The integrate-and-fire (IF) model is a simplified neuronal model that captures spike generation by integrating synaptic inputs until membrane potential reaches a threshold, at which point a spike is emitted. First proposed by Louis Lapicque in 1907 and refined with leak (leaky integrate-and-fire, LIF), it remains a standard tool for modeling neural populations and network dynamics due to its computational efficiency.	Muscle synergy analysis decomposes complex motor behavior into a small set of coactivated muscle groups (synergies or motor primitives). Pioneered by Marc Tresch and colleagues studying frog motor control, this approach reveals how the nervous system simplifies the control of many muscles by organizing them into task-relevant combinations.
