Images received by the retina are also processed in certain regions of the brain other than just the visual cortex, one of the more obscure regions involved lying in the lower temporal lobe. It seems that D. B. may have been basing his ‘guesses’ on information gained by this lower temporal region. Nothing was directly perceived consciously by the activation of these regions, yet the information was there, to be revealed only in the correctness of D. B. ’s ‘guesses’. In fact, after some training, D. B. was able to obtain a limited amount of actual awareness in respect of these regions.
