近年来听觉表象开始得到关注，相关研究包括言语声音、音乐声音、环境声音的听觉表象三类。本文梳理了认知神经科学领域对上述三种听觉表象所激活的脑区研究，比较了听觉表象和听觉对应脑区的异同，并展望了听觉表象未来的研究方向。

Auditory imagery is the introspective persistence of an auditory experience, including one constructed from components drawn from long- term memory, in the absence of direct sensory instigation of that experience. In recent years, researchers became much more interested in the study of auditory imagery. According to the kinds of sounds that can generate the auditory imagery, we classifted auditory imagery research into three types, verbal auditory imagery, musical auditory imagery and environmental auditory imagery. With the development of modern technology and cognitive neuroscience, researchers explored the activated brain areas when the auditory imagery emerged from these three different types of sounds. Recent findings of verbal auditory imagery suggest that auditory cortex and brain regions associated with attention, verbal monitoring and articulation were more activated when normal subjects imaged verbal stim- all, while patients witb schizophrenia who were prone to verbal hallucinations brought on by increased activity in theBroca~ and Wer- nicke~ areas exhibited an attenuated deactivation in the left superior temporal gyrus which was associated with verbal monitoring. It sug- gests that the left superior temporal gEcrus was one of the key regions through which normal people can discriminate verbal imagery fi＇om auditory stimuli. In musical auditory imagery research, the superior temporal gyms, as well as areas of the fi＇ontal lobe, parietal lobe and supplementary motor area were activated in musical auditory imagery and represented hemispheric processing asymmetries. Further, there is evidence that parietal cortex has played an important role in mental reversal of imagined melodies as well as other mental trans- formation tasks, such as mental rotation in the visual imagery. In addition, EEG studies showed that musical auditory imagery interacted with music perception and encoded pitch and loudness information of music. There was existence of hemispheric processing asymmetries in environmental auditor）, imagery which depended on the secondary auditory cortex rather than the primary auditory cortex. And we compared the similarities and differences of the brain areas between auditory imagery, and auditory perception. There were large numbers of brain regions overlap between auditory imagery＂ and perception, but not all. At the end, there is some advice for further research. Ob- viously, researchers attempted to find out the association of auditory imagery and perception. Although they were similar in the neural mechanism, they were different;and we should unfold the specific mechanism of auditory imagery. Auditory imagery is an important ele- ment of cognitive processing related to language, music, and other environmental stimuli, but the studies of environmental auditory im- agery are deficient. Moreover, brain regionsactivated byauditory imageryare associated with other cognitive processes, such as attention, memory and self - control. It indicates auditory imagery has common connection with other cognition function. It is worthy to explore the relationships between auditory imagery and other cognitive processes for elucidating the main mechanism of auditory imagery. Notably, there were substantial findings of mental transformation in visual imagery, while it was limited in auditory imagery which was a crucial skill to play＂ any music implement. Finally, sludies of auditory imagery neural mechanism have its clinical application value since abnormalities in cognitive processing related to auditory imagery are exhibited in or contribute to psychopathology.
