A commentary on a prior article proposing that neurotypical subjective experience arises from a hippocampal simulation process. The commentary engages with the philosophical and neuroscientific dimensions of consciousness, situating the discussion within the categories of philosophy of consciousness and neuroanatomy.
This reply critically engages with Behrendt's proposal that the hippocampus functions as a wormhole-like gateway to consciousness. It argues against the idea that hippocampal theta oscillations alone can explain the subjective unity of conscious experience, highlighting instead the distributed nature of neural correlates of consciousness and the need for a broader network perspective. The reply emphasizes that while the hippocampus plays a role in memory and spatial navigation, its specific contribution to consciousness remains unclear and likely involves interactions with other brain regions.
Different theories of visual awareness—the global workspace theory, local visual processing theories, and the higher-order representation theory—are supported by different neural correlates. Studying these neural correlates can advance theoretical understanding, but resolving disagreements between interpretations of neural evidence also requires addressing conceptual issues.
For thirty years, evidence supported the view that attention is necessary for conscious perception. Recent findings have challenged this view, suggesting consciousness and attention may dissociate. This paper reviews the debate and argues that the evidence for dissociation is not decisive. The authors present an opinionated overview, highlighting that the relationship between attention and consciousness remains controversial and under investigation.
