Spike-Timing Dependent Plasticity (STDP) is characterized by a wide range of temporal kernels. However. much of the theoretical work has focused on a specific kernel - the "temporally asymmetric Hebbian" learning rules. Previous studies linked excitatory STDP to positive feedback that can account for the emergence of response selectivity. https://allfixelectricales.shop/product-category/brass-flare-union/
