The Challenge of Understanding Consciousness

Understanding consciousness remains a significant challenge in both neuroscience and philosophy. Researchers have explored various dimensions of consciousness without reaching a consensus on its definition or mechanism. Despite advancements, the intersection between subjective experience and objective measurements complicates inquiries into consciousness. Engaging with the hard problem of consciousness, scientists aim not only to catalog neural responses but also to decipher whether consciousness can be quantified in non-human systems and potentially artificial ones.
