(1/3) Abstract concepts like the mind and consciousness were once seen as distinct from the physical brain. However, Greenfield seeks to understand how these ideas are connected to brain structure. The mind is viewed as the result of adaptive, plastic connections between neurons, reflecting the brain’s ability to rewire itself in response to experiences. This ongoing adaptation personalises the brain, shaping an individual's unique mental landscape. Consciousness, on the other hand, is seen as more fleeting, emerging from large-scale neural assemblies that form and dissolve rapidly.
This distinction can be understood as the difference between neural plasticity and neural assemblies. Plasticity refers to long-lasting changes in the brain’s wiring, meaning the mind is shaped by experiences over time. In contrast, neural assemblies, which are associated with consciousness, are transient, coordinating brain activity on a larger scale but only for short periods. 2 replies
