Two-photon imaging reveals a novel role of the hierarchical visual cortical network in marmoset monkeys (IMAGE)
Caption
Scientists from the University of Tokyo performed two-photon imaging in the visual cortex of marmoset monkeys to examine spontaneous and visual stimulus-evoked neuronal activities (top left). Visual cortical neurons showed vigorous spontaneous activities even in the absence of visual stimuli (top right). Spontaneous and visually evoked activities are progressively orthogonalized as they propagate through the hierarchical visual cortical network.
