Creierul nu uită ce a 'văzut': Deciziile ni se pot schimba într-o clipă

Researchers at MIT have discovered a brain circuit that compares current visual information with recent past experiences, influencing decision-making. This circuit connects the pulvinar in the thalamus to the frontal cortex, allowing the brain to evaluate whether to maintain or change a previous response. Experiments on mice showed that their choices were affected by the similarity of previous tasks. Stimulation of specific pulvinar areas altered decision-making, indicating a causal role in sensory comparison. The findings may have implications for understanding autism, though caution is advised in interpreting results from animal studies.
