“…3). This result is in line with several observations on sound and music imagery, which found activity only in the secondary auditory cortex but not in A1 (Ducreux et al, 2003;Halpern and Zatorre, 1999;Kraemer et al, 2005;Yoo et al, 2001;Zatorre and Halpern, 2005). It is interesting in this regard that our subjects rated the vividness of imagined singing as high and reported no problems in attention during the imagery task.…”

“…Primary auditory cortex activation in the absence of auditory input has been found for short gaps of silence (lasting 2-5 s) that were inserted at different points during the soundtrack of familiar music (Kraemer et al, 2005) and in a sound detection task during the preceding silence of the emerging sounds (Voisin et al, 2006). A further report of primary auditory activation during mental imagery of a computer generated monotone (C maj ) comes from Yoo and colleagues (Yoo et al, 2001) but a recent inspection of the exact locus of activation indicated in that study questioned their results (Halpern et al, 2004). More compelling evidence exists regarding the contribution of secondary (or association) auditory cortex during mental imagery of complex, meaningful sounds (Bunzeck et al, 2005;Halpern and Zatorre, 1999;Halpern et al, 2004;Shergill et al, 2000;Shergill et al, 2001;Zatorre et al, 1996).…”

Activation maps of 16 professional classical singers were evaluated during overt singing and imagined singing of an Italian aria utilizing a sparse sampling functional magnetic imaging (fMRI) technique. Overt singing involved bilateral primary and secondary sensorimotor and auditory cortices but also areas associated with speech and language production. Activation magnitude within the gyri of Heschl (A1) was comparable in both hemispheres. Subcortical motor areas (cerebellum, thalamus, medulla and basal ganglia) were active too. Areas associated with emotional processing showed slight (anterior cingulate cortex, anterior insula) activation. Cerebral activation sites during imagined singing were centered on fronto-parietal areas and involved primary and secondary sensorimotor areas in both hemispheres. Areas processing emotions showed intense activation (ACC and bilateral insula, hippocampus and anterior temporal poles, bilateral amygdala). Imagery showed no significant activation in A1. Overt minus imagined singing revealed increased activation in cortical (bilateral primary motor; M1) and subcortical (right cerebellar hemisphere, medulla) motor as well as in sensory areas (primary somatosensory cortex, bilateral A1). Imagined minus overt singing showed enhanced activity in the medial Brodmann's area 6, the ventrolateral and medial prefrontal cortex (PFC), the anterior cingulate cortex and the inferior parietal lobe. Additionally, Wernicke's area and Brocca's area and their homologues were increasingly active during imagery. We conclude that imagined and overt singing involves partly different brain systems in professional singers with more prefrontal and limbic activation and a larger network of higher order associative functions during imagery.

“…Precuneus activation has also been reported for auditory imagery (Yoo et al, 2001) and for the recognition of familiar sounds (Maeder et al, 2001) and voices (Nakamura et al, 2001)-as well as for recognition memory in general (Henson et al, 2000;Herath et al, 2001). Precuneal activity in the present study, thus, might alternatively be taken to suggest that earlier learned words elicit a greater recognition response in the brain.…”

Distinct brain representations for early and late learned words

Recently there has been a renewed interest in cognitive psychology on the effects of the age of word acquisition (AoA) on lexical processing. In particular, it is currently unclear whether AoA or word frequency are better predictors of word recognition. To date no study has investigated the neural bases of the AoA effect or attempted to dissociate it from word frequency. We report a visual and an auditory event-related fMRI experiment investigating the influence of AoA and word frequency on neural activity, and show that AoA modulates brain areas that are not influenced by word frequency. The precuneus was activated for early learned words across auditory and visual presentation modalities. Additional activity in the auditory cortex was observed specifically for the reading of early acquired words. Late learned words, in contrast, led to a selective activation increase in lateral inferior frontal areas. These findings support models that suggest that early and late learned words are represented differently in the brain. They further allow to specify the nature of the represenational differences, namely that early learned words are represented in the brain in a more sensory manner than late learned words.

“…Imagination seems to activate the same brain structures within the same modality as actual perception (Kosslyn et al, 2001). In fact, imagery of various sensory stimulations and ocular motor performances activate areas that overlap with those activated under "real" conditions such as acoustic (Yoo et al, 2001;Halpern and Zatorre, 1999), visual (Mellet et al, 1998;Wexler et al, 1998), and ocular motor areas (Bodis-Wollner et al, 1997;Law et al, 1997). Our study strikingly showed that several sensory modalities were activated simultaneously in single subject and group analyses.…”

Eye closure in darkness animates sensory systems

Single subject and group analyses (n ϭ 12) showed that the eyes-open and eyes-closed states in complete darkness considerably and consistently differ in the patterns of associated brain activation in fMRI. During nonchanging external stimulation, ocular motor and attentional systems were activated when the eyes were open; the visual, somatosensory, vestibular, and auditory systems were activated when the eyes were closed. These data suggest that there are two different states of mental activity: with the eyes closed, an "interoceptive" state characterized by imagination and multisensory activity and with the eyes open, an "exteroceptive" state characterized by attention and ocular motor activity. Our study also shows that the chosen baseline condition may have a considerable impact on activation patterns and on the interpretation of brain activation studies.
