概要	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.	Brain-computer interface (BCI) using motor imagery decodes the intent to move from brain activity (typically EEG) recorded while subjects imagine movement without actual muscle contraction. Pioneered by Gert Pfurtscheller and colleagues, motor imagery BCIs enable communication and control for paralyzed patients and enhance motor learning in rehabilitation.
