Researchers introduce a new neurocomputational model of the human brain. This model could bridge the gap in our understanding of artificial intelligence and the biological mechanisms underlying mental disorders.
A study by an international group of researchers* introduces a new neurocomputational model of the human brain that could shed light on how the brain develops complex cognitive abilities and advance neural artificial intelligence research.
The model describes neural development over three hierarchical levels of information processing. The first sensorimotor level explores how the brain's inner activity learns patterns from perception and associates them with action; then the cognitive level examines how the brain contextually combines those patterns; and finally, the conscious level considers how the brain dissociates from the outside world and manipulates learned patterns (via memory) that are no longer accessible to perception.
The model demonstrates how the Neuro-AI convergence highlights biological mechanisms and cognitive architectures that can fuel the development of the next generation of artificial intelligence and even ultimately lead to artificial consciousness. Reaching this milestone may require integrating the social dimension of cognition.
Future work is now looking at integrating biological and social dimensions at play in human cognition. The team has already pioneered the first simulation of two whole brains in interaction. Anchoring future computational models in biological and social realities will not only continue to shed light on the core mechanisms underlying cognition but will also help provide a unique bridge to artificial intelligence towards the only known system with advanced social consciousness: the human brain.
