Individual Neuron

Individual neurons, the fundamental units of the nervous system and artificial neural networks, are the focus of intense research aimed at understanding their function and contribution to overall network behavior. Current research emphasizes disentangling the complex roles of individual neurons, often revealing polysemantic behavior (encoding multiple features) and exploring methods to isolate their specific contributions through techniques like circuit analysis and concept vector extraction. These investigations, employing diverse model architectures including convolutional neural networks and transformers, are crucial for improving the interpretability and reliability of artificial neural networks and advancing our understanding of biological neural circuits.
