How cortex reorganizes
Article Abstract:
Experiments show that the receptor surfaces in the cortex of the brain are capable of re-organization after partial deactivation or a change in the activation patterns. The de-activation may induce damage to the sensory nerves from the skin, retinal lesions or loss of hair cells from the cochlea. Re-organization depends on the potentiation of existing inactive neural connections and the formation of new connections. The competing source of activation is removed by retinal lesions and the sub-threshold level of the horizontal connections' influences reach super-threshold levels.

Vision without awareness
Article Abstract:
The investigation of blindsight in monkeys reveals that monkeys have difficulty in detecting an object, unlike humans affected with blindsight. Humans affected with blindsight are capable of detecting objects in space, though they are not capable of identifying them. The inability of monkeys affected with blindsight to detect objects in space indicates that the V1 lesions present in humans are absent in the monkeys.
