Topic: low dimensional neural activity

Columnar organization is the hallmark of mature visual cortex in primates and carnivores, and is often assumed to be unique to those areas. Such an organization is already evident in the developing visual cortex (V1) well before eye-opening, where correlated modular spontaneous activity predicts future sensory-evoked representations. The multiple computational models proposed to account for this modular activity suggest several biologically plausible regimes which can produce modular activity and long-range correlations. Notably, these potential mechanisms are highly unlikely to be specific in
