K_5_15 — Neural Fractals & the Edge of Chaos: Brain Criticality and Complexity

The brain is poised at a critical point between order and chaos — and its fractality is not an accident but a functional necessity. In 2003, John Beggs and Dietmar Plenz published one of neuroscience's landmark papers: t

K_5_09 — Consciousness and Time Perception: How the Brain Creates Now

Time is perhaps the most intimate dimension of consciousness: every conscious experience occurs in time, and our sense of temporal flow — the feeling that time "passes," that the present moment is real and moving forward
