Doctor's Optic Nerve

The optic nerve stretches as a narrow, fragile tunnel of neural tissue where vision’s data first enters the brain’s processing core. Here, the Doctor’s mind shows its first signs of intrusion—threads of grey matter cling to the tunnel walls like frayed cables, their usual ordered patterns disrupted by swelling and shadow. The space feels pressurized, each breath of neural fluid carrying the sting of infection even before visible damage appears. When Leela kicks the Doctor mid-step, the sudden jerk sends tendrils of deteriorating tissue trembling, exposing gaps where microscopic invaders have already gained purchase. The air hums with the low-grade static of malfunctioning synapses, while the distant pulse of the cardiovascular system vibrates through the tunnel’s length, a reminder of how exposure here could unravel the entire mind.
