Neuroanatomical and perceptual deficits in auditory agnosia : a study of an auditory agnosia patient with inferior colliculus damage
TLDR
It is argued that the patient experiences auditory agnosia be- cause the brain stem injury prevents the transmission of critical auditory information to the auditory cortex.

TLDR
The shortcomings of current neuropsychological interpretations are discussed and it is concluded that they present a challenge to establish a conceptual framework, which would permit the resolution of both neurodynamic and developmental points of view.
How Extended Is Wernicke's Area? Meta-Analytic Connectivity Study of BA20 and Integrative Proposal
Understanding the functions of different brain areas has represented a major endeavor of contemporary neurosciences. The purpose of this paper was to pinpoint the connectivity of Brodmann area 20…

TLDR
This analysis indicates a close structural analogy to the syndrome of perceptive visual agnosia, and places great importance in the relationship between approaches and models of cognitive psychology (Neisser, 1967) which is seen as important for further theoretical development in neuropsychology.

Functional Mapping of the Human Auditory Cortex: fMRI Investigation of a Patient with Auditory Agnosia from Trauma to the Inferior Colliculus
TLDR
Auditory agnosia reflects dysfunction of the auditory ventral stream, and leftward localization bias, preserved audiovisual integration, and phoneme perception are explained by preserved processing in her right auditory dorsal stream.
CT Scan Correlates of Sound Recognition Defect in Aphasia
On pure word deafness, temporal processing, and the left hemisphere
TLDR
A woman with PWD resulting from a circumscribed unilateral infarct involving the left superior temporal lobe who demonstrated significant problems processing transitional spectrotemporal cues in both speech and nonspeech sounds is reported on.

Dichotic Word-Perception of Aphasic and Normal Subjects
TLDR
The present investigation examined the role of the right cerebral hemisphere in linguistic perception following a left cerebral insult which had resulted in aphasia and found a significant left-ear preference for aphasic Ss who were more than 6 mo. post-cerebral insult.
AUDITORY AGNOSIA WITHOUT APHASIA.
TLDR
Only one case of an agnosia for sounds without evidence of aphasia either in the history or in the present clinical picture has so far been on record, and this patient was a 52-year-old Mexican man who was examined with the aid of an interpreter.

WORD DEAFNESS AND WERNICKE'S APHASIA: Report of Cases and Discussion of the Syndrome
TLDR
"Paraphasia" consists of loss of comprehension of spoken language and loss of ability to write and read (silently), with power of articulate speech retained but distorted in that words and syllables are misplaced and mispronounced—paraphasia.
The Problem of Agnosia in the Light of a Case of Pure Word Deafness
TLDR
A forty-five year old man showed after a probable vascular lesion of the brain a marked aphasic disorder and absence of response to auditory stimuli, and a gradual limited improvement in the word sound perception occurred, but there was still a considerable defect after 18 months of observation.
Development of above normal language and intelligence 21 years after left hemispherectomy
TLDR
Neuropsychologic follow-up studies of a 5-year-old boy who had left hemispherectomy for seizures showed that he had developed superior language and intellectual abilities, contradict reports of restricted development of language functions after left and of nonlanguage functions after right hemisphereCTomy for perinatal lateralized brain lesions.
