The results also lead to a suggestion about the neural basis of repetition priming: following presentation of a stimulus, less neural activity is required to process the same stimulus.International Survey Highlights Great Public Desire to Seek Early Diagnosis of Alzheimer's,, 2013. The results provide evidence for selective activation of the human hippocampal region in association with memory function. (iii) Right prefrontal cortex was activated in the memory-minus-baseline condition.

(ii) In the priming-minus-baseline comparison, there was reduction in blood flow in the right posterior cortex.

The right hemispheric locus suggests that performance is driven by the visual characteristics of the words rather than by semantic or phonetic analysis. (i) The memory task engaged the right hippocampal region when the memory task was compared to either the baseline or the priming condition.

Local blood flow was then monitored during a 40-sec period while subjects (i) silently viewed word stems, (ii) completed stems to form the first words to come to mind, but the stems were not the beginnings of any study words (baseline), (iii) completed stems and half of them could form study words (priming), or (iv) tried to recall study words, and half of the stems could form these words (memory). Prior to each task, subjects studied a list of words. We studied regional cerebral blood flow using the H2 15O method while normal subjects performed four similar tasks involving three-letter word beginnings (stems).
