Bosking notes that with VCPs tested in the past, subjects did not really see or perceive coherent visual forms, instead they tended to see blobs of light in front of them in various locations. “Our ...

But those purple and green blobs aren't the floating remains of somebody's drink. They're mysterious cells in the brain's visual cortex called oligodendrocyte precursor cells (OPCs).

But those purple and green blobs aren't the floating remains of somebody's drink. They're mysterious cells in the brain's visual cortex called OPCs. The visual cortex processes everything we see.

The researchers found that both the real blobs and hallucinations seemed to be perceived in the visual cortex, and they created a computer model of the visual cortex.

Oligodendrocyte Precursor Cells, or OPCs (the purple and green blobs above), prune unneeded synapses (the silver streaks) in the brain’s visual cortex in response to new information and experiences.

Patches in primary visual cortex (V1) rich in cytochrome oxidase were thought to contain unoriented, color-opponent neurons. Here the authors measure orientation tuning in V1 neurons using acutely ...

The remembered image was a large, blurry blob at every stage. ... the researchers created a model of the visual cortex that had different levels of neurons with receptive fields of increasing size.
