A growing faction of neuroscientists is challenging the traditional view that the cortex is the sole seat of consciousness, proposing instead that the subcortex may play a crucial role. This shift could have profound implications not just for our understanding of human consciousness but also for the development of artificial intelligence (AI). If consciousness can exist without a fully developed cortex, it raises questions about the ethical treatment of AI systems designed to mimic human-like consciousness.
Recent studies have shown that even organisms lacking a cortex can exhibit behaviors suggestive of consciousness. For instance, children with hydranencephaly, who are born without a cortex, display emotional responses and interactions that challenge our understanding of what it means to be conscious. This evidence suggests that consciousness might not be the exclusive domain of complex cognitive processes but could also emerge from more primitive brain structures.
The implications for AI are significant. As companies like OpenAI and Google DeepMind push the boundaries of what AI can achieve, understanding the neural correlates of consciousness could inform the development of more advanced AI systems. If consciousness can arise from simpler neural architectures, AI could potentially be designed to exhibit forms of consciousness without replicating the full complexity of human cognition.
