Just came across an elegant new #SNN framework called #nervos by Maskeen and Lashkare, which implements a two layer SNN w/ local #STDP #learning to classify, e.g., #MNIST digits. Here is an example, where I apply it to a 6-class subset of MNIST. The model reaches around 85% accuracy & the learned synapses show digit-like patterns. Quite impressive in my view, given the simplicity of the architecture & the local learning rule:

Spike-timing-dependent #plasticity (#STDP) is a core rule in #ComputationalNeuroscience that adjusts #synaptic strength based on precise pre- vs. postsynaptic #spike timing, enabling #TemporalCoding and #learning in #SNN. In this post, I summarize its mathematical formulation, functional consequences for learning and #memory along with a simple #Python example:

Recent findings show that hippocampal neurons shift their activity backward in time as learning occurs, enabling anticipation of rewards before they happen. Using calcium imaging in mice performing a delayed nonmatching-to-location task, the study tracked the same neurons over weeks and observed a backpropagation of tuning from reward delivery to earlier moments, including the moment of correct touchscreen choice. The results portray the hippocampus as a dynamic predictive map that reorganizes with experience to guide future behavior.

This work is of interest to psychology because it provides concrete neural evidence for predictive coding and memory-based anticipation, illustrating how learning reshapes mental representations to forecast future events. It links memory, prediction, and action in a measurable neural framework.

#NeuralPlasticity & #learning are distinct but interrelated processes. #Plasticity denotes biological change in #NeuralSystems, while learning is its functional expression in #NetworkDynamics & #behavior. Learning arises from coordinated plastic processes, reshaping #NeuralStateSpace & #attractors to support stable yet flexible representations. Here's a new post on these concepts & their implications for #ComputationalNeuroscience:

We've seen the GOP go all in on autocracy and fascism. We can only understand the true danger we face when we realize how easily the language of dehumanization of a group can become hardwired and become very difficult to dislodge.
