J., Frith, Liddle, & Frackowiak, 1993). The data to support the hypothesis was acquired from 4 groups of 6 subjects, one group of 6 normal subjects and three groups of 6 schizophrenic patients. Each subject was scanned 6 times during the performance of three-word production tasks. The first task (A) was a verbal fluency task that required subjects to respond with multiple words that began with a given letter. The second task (B) was a semantic categorisation task where the subject responded “man-made” or “natural” depending on the heard noun. The last task (C) was a word shadowing task where the subject simply repeated what was heard. To support and analyse the theory of dysconnectivity, three different tasks were used as to create variance in cerebral activity and widespread blood flow changes in the prefrontal and temporal …show more content…
For example, auditory hallucinations may be the result of a failure to modulate neural activity associated with intrinsically generated language representations in the temporal regions hence resulting in the perception of words that are experienced as extrinsic (Friston & Frith, 1995). Friston and Frith (1995) conclude that centered in the temporal regions is the functional anatomy of language related perceptual representations and that it follows that there might be something quite specific about fronto-temporal disconnection and
