Latency of the different processing steps along the visual pathway. Though this system is highly inter-connected, one can follow the sequence of activations whenever an image (here a yellow star) is flashed in front of the eyes.
Summary[edit]
| Description |
English: Different areas are schematically represented by ellipses and arrows denote the fastest feed-forward activation, ordered with respect to their activation latency. In order, the retina is first activated (20 − 40 ms) then the thalamus and the primary visual cortex (V1, 60 − 90 ms). Visual information used for object recognition follows the temporal lobe to reach the infero-temporal area (IT, 150 ms), and then the prefrontal cortex (PFC, 180 ms) which modulates decision making and the Motor cortex (MC, 220 ms) which mediates a motor action which is then relayed through the spinal cord to trigger finger muscles, with latencies about 280 − 400 ms. |
