Six subjects with musical hallucinations following acquired deafness are described. The subjects all experienced the condition in the absence of any other features to suggest epilepsy or psychosis. I propose a neuropsychological model for the condition consistent with detailed observation of the subjects' phenomenology. The model is based on spontaneous activity within a cognitive module for the analysis of temporal pattern in segmented sound. Functional imaging was carried out to test the hypothesis that musical hallucinosis is due to activity within such a module, for which the neural substrate is a distributed network distinct from the primary auditory cortex. PET was carried out on the six subjects to identify areas where brain activity increased as a function of the severity of the hallucination. In a group analysis, no effect was demonstrated in the primary auditory cortices. Clusters of correlated activity were demonstrated in the posterior temporal lobes, the right basal ganglia, the cerebellum and the inferior frontal cortices. This network is similar to that previously demonstrated during the normal perception and imagery of patterned-segmented sound, and is consistent with the proposed neuropsychological and neural mechanism.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 December 2022.
All research outputs
#7,743,048
of 26,459,924 outputs
Outputs from Brain
#4,916
of 7,839 outputs
Outputs of similar age
#12,340
of 39,590 outputs
Outputs of similar age from Brain
#13
of 27 outputs
Altmetric has tracked 26,459,924 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 7,839 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 27.9. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 39,590 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
