Biophysical modeling reveals how recording geometry shapes representations of cortical activity

Extracellular electrophysiological recordings reflect both the organization of neural activity and the geometry through which that activity is sampled. Here, we used biophysical modeling and experimental recordings from the macaque auditory cortex to determine how cortical activity is transformed across neural sources,...

A Synchronization-Driven Learning Rule for Pattern Separation in Self-Organizing Probabilistic Spiking Neural Networks

This work systematically investigated how feedback inhibition influences network dynamics, stability, synchronization, and pattern separation efficacy and demonstrated that moderate inhibition produces an optimal balance between excitatory and inhibitory activity, maximizing pattern separation while preventing both exc...

Context-Aware Evidence-Gated Plasticity for Multi-Goal Learning in Spiking Neural Networks

These results demonstrate that spiking navigation circuits can learn goal-directed behavior using local plasticity, but robust multi-goal learning benefits from context-specific evidence-based consolidation.
