Acting without 'seeing.'(unconscious processing of visual stimulus)

Article Abstract:

Seeing is not a single process but involves both conscious object recognition and unconscious processing of this stimulus which affects action. Actual object recognition involves the ventral path from the occipital to the temporal cortex while the actions caused by the stimulus involve the dorsal route from the occipital lobe to the parietal lobe. Normally these two processes are related and the meaning of objects affects actions and in brain damaged patients residues of this interaction can still be seen.

Imaging unconscious semantic priming

Article Abstract:

Briefly presented and masked visual words may however facilitate the subsequent processing of related words, known as masked priming. Masked primes may activate cognitive processes without access to consciousness. Behavioral and brain-imaging methods were used to estimate the depth of processing of masked numerical primes. Results suggested that masked stimuli have a large influence on electrical and haemodynamic measures of brain activity.
