TL;DR
The proposed method allowed for the analysis of brain areas responsive to the event of auditory imagery while the results suggest that auditory imagery and actual audition share common neural substrates.
Abstract
We used event-related fMRI methodology to investigate human brain activity during auditory imagery. A series of susceptibility-weighted MR images covering the whole brain were acquired to obtain blood oxygenation level-dependent (BOLD) signal changes associated with the imagery event of hearing simple monotone. Group analysis across the 12 right-handed subjects revealed activations in the medial and inferior frontal gyri, precuneus, middle frontal gyri, superior temporal gyri, and anterior cingulate gyri. Bilateral primary and secondary auditory areas in the superior temporal gyri also exhibited the event-related MR signal changes. The proposed method allowed for the analysis of brain areas responsive to the event of auditory imagery while our results suggest that auditory imagery and actual audition share common neural substrates.

The approach is predicated on an extension of the general linear model that allows for correlations between error terms due to physiological noise or correlations that ensue after temporal smoothing, and uses the effective degrees of freedom associated with the error term.

Human Brain Mapping?sparse? temporal sampling in auditory fMRI
883 Citations1999Deborah A. Hall, Mark Haggard +6 more
“sparse” temporal sampling is presented, using this technique, single volumes of brain images are acquired at the end of stimulus and baseline conditions, and the effective auditory stimulus for the activation is not masked by the scanner noise.

Findings resolve a debate in the literature about whether imagery activates early visual cortex and indicate that visual mental imagery involves 'depictive' representations, not solely language-like descriptions12–14.

Functional MRI was used to observe focal changes in blood flow in the brains of 10 healthy volunteers performing a mental rotation task, and data are consistent with the hypothesis that mental rotation engages cortical areas involved in tracking moving objects and encoding spatial relations.

Auditory hallucinations may be mediated by a distributed network of cortical and subcortical areas that is associated with activation in the inferior frontal/insular, anterior cingulate, and temporal cortex bilaterally and may have identified different components of this network.

The results of Experiments 1 and 2 suggest that phonological processing per se does not necessarily recruit frontal areas, and postulate that frontal activation is a product of segmentation processes in speech perception, or alternatively, working memory demands required for such processing.

The stroboscopic event-related method appeared effective in minimizing effects of the interaction between scanning noise and experimental auditory stimulation; it adds useful temporal information to the spatial resolution afforded by fMRI in studies of human auditory function, while allowing presentation of auditory stimuli on a silent background.

241 Citations1996Philip McGuire, David Silbersweig +4 more
A predisposition to verbal hallucinations in schizophrenia is associated with a failure to activate areas implicated in the normal monitoring of inner speech, whereas the absence of a history of hallucinations may be linked to reduced activation in an area concerned with verbal prosody.

These results are consistent with the use of the ‘articulatory loop' during both inner speech and auditory verbal imagery, and the greater engagement of verbal self-monitoring during auditoryverbal imagery.
