“…These findings are somewhat difficult to interpret in light of the fact that the paradigm mixed together rhythmic, pitch, and timbre irregularities within test conditions. To complicate the issue further, other studies have shown definite right-sided contributions to temporal pattern per- ception (Robinson and Solomon, 1974;Michel et al, 1980;Peretz, 1990;Kester et al, 1991;Penhune et al, 1999).…”

This review article highlights state-of-the-art functional neuroimaging studies and demonstrates the novel use of music as a tool for the study of human auditory brain structure and function. Music is a unique auditory stimulus with properties that make it a compelling tool with which to study both human behavior and, more specifically, the neural elements involved in the processing of sound. Functional neuroimaging techniques represent a modern and powerful method of investigation into neural structure and functional correlates in the living organism. These methods have demonstrated a close relationship between the neural processing of music and language, both syntactically and semantically. Greater neural activity and increased volume of gray matter in Heschl's gyrus has been associated with musical aptitude. Activation of Broca's area, a region traditionally considered to subserve language, is important in interpreting whether a note is on or off key. The planum temporale shows asymmetries that are associated with the phenomenon of perfect pitch. Functional imaging studies have also demonstrated activation of primitive emotional centers such as ventral striatum, midbrain, amygdala, orbitofrontal cortex, and ventral medial prefrontal cortex in listeners of moving musical passages. In addition, studies of melody and rhythm perception have elucidated mechanisms of hemispheric specialization. These studies show the power of music and functional neuroimaging to provide singularly useful tools for the study of brain structure and function. Anat Rec Part 288A: 435-446, 2006. Published 2006

“…Of these, 4 were nonverbal auditory agnosics (Albert et al, 1972;De La Sayette et al, 1994;Habib et al, 1995;Taniwaki et al, 2000), 8 were verbal auditory agnosics (Buchman et al, 1986, cases 1 and 2;Coslett et al, 1984;Klein and Harper, 1956;Mendez and Rosenberg, 1991;Otsuki et al, 1998;E. Wang et al, 2000;Papathanasiou, 1998), and 4 were complete auditory agnosics (Garde and Cowey, 2000;Kaga et al, 2000;Michel et al, 1980;Rosati et al, 1982). Amnesia was not noted in any of these 17 case reports.…”

This special issue of Cortex focuses on the relative contribution of different neural networks to memory and the interaction of 'core' memory processes with other cognitive processes. In this article, we examine both. Specifically, we identify cognitive processes other than encoding and retrieval that are thought to be involved in memory; we then examine the consequences of damage to brain regions that support these processes. This approach forces a consideration of the roles of brain regions outside of the frontal, medialtemporal, and diencephalic regions that form a central part of neurobiological theories of memory. Certain kinds of damage to visual cortex or lateral temporal cortex produced impairments of visual imagery or semantic memory; these patterns of impairment are associated with a unique pattern of amnesia that was distinctly different from the pattern associated with medial-temporal trauma. On the other hand, damage to language regions, auditory cortex, or parietal cortex produced impairments of language, auditory imagery, or spatial imagery; however, these impairments were not associated with amnesia. Therefore, a full model of autobiographical memory must consider cognitive processes that are not generally considered 'core processes,' as well as the brain regions upon which these processes depend.

SUMMARYThe symptoms of two patients with bilateral cortical auditory lesions evolved from cortical deafness to other auditory syndromes: generalised auditory agnosia, amusia and/or pure word deafness, and a residual impairment of temporal sequencing. On investigation, both had dysacusis, absent middle latency evoked responses, acoustic errors in sound recognition and matching, inconsistent auditory behaviours, and similarly disturbed psychoacoustic discrimination tasks. These findings indicate that the different clinical syndromes caused by cortical auditory lesions form a spectrum of related auditory processing disorders. Differences between syndromes may depend on the degree of involvement of a primary cortical processing system, the more diffuse accessory system, and possibly the efferent auditory system.Since the original description in the late nineteenth century, a variety of disorders has been reported from bilateral lesions of the auditory cortex and its radiations. The clinical syndrome of cortical deafness in a woman with bitemporal infarction was described by Wernicke and Friedlander in 1883.' The term auditory agnosia was used by Freud in 1891,2 and has been used alternately for two observed syndromes: a selective decrease in recognition of non-verbal sounds and a generalised decrease in recognition of both verbal and non-verbal sounds. Lissauer (1890) proposed the existence of an apperceptive agnosia resulting from inability to synthesise sensory information into an adequate percept.3 Kussmaul (1877) first described a patient with pure word deafness,4 and Bernard (1889) noted an amusia where melodies lose their musical character. I Since that time, many other cases have been reported and attributed to lesions involving the cortical auditory areas.6-10It is still not fully understood how dysfunction of the cortex results in these diverse syndromes and whether they are functionally related or truly distinct.3 Investigators disagree as to whether true deafness can result from cortical lesions.6 1112 Case
