Incorporating New Information in the Mammal Brain

The mammal brain decides to incorporate new information by updating weights only in times of surprise or new information, potentially regulated by specific neuromodulators. Unlike neural networks, mammalian brains do not continuously learn everything but selectively update weights when facing failed predictions, leading to reduced catastrophic forgetting. Another unique aspect is the 'Eureka moment' in humans, where new confusing information is not simply added to the model of the world but is critically analyzed to fit into the existing model, enabling robustness and generalization across tasks. This nuanced process of rejecting or accepting new information based on its alignment with the established model of the world allows for more effective continual learning and generalization in mammalian brains.
