The effects of musical practice on cognition are well established yet rarely compared with other kinds of artistic training or expertise. This study aims to compare the possible effect of musical and theater regular practice on cognition across the lifespan. Both of these artistic activities require many hours of individual or collective training i...
Article
Background: Encoding of new information is considered to be impossible in people with Alzheimer's disease (PWAD) at a moderate to severe stage. However, a few case studies reported new learning under special circumstances, especially with music. Objective: This article aims at clarifying PWAD's learning capacities toward unknown material under m...
Chapter
Musical interventions are now largely supported by many national health agencies as pertinent nonpharmacological care in pathological aging. Particularly, in the context of neurodegenerative diseases, such as Alzheimer’s, the interest of these interventions is typically to allow, notably during the early stages of the disease, significant reduction...

Article
La question de l’existence de substrats cérébraux spécifiques à la musique n’est pas nouvelle. En neurologie, à la fin du 19e siècle, les premières observations de dissociations cliniques montrant des patients aphasiques sans trouble amusiques ou l’inverse, ont appuyé initialement l’idée de régions cérébrales dédiées spécifiquement à la fonction mu...
Article
Full-text available
Because of permanent use-dependent brain plasticity, all lifelong individuals' experiences are believed to influence the cognitive aging quality. In older individuals, both former and current musical practices have been associated with better verbal skills, visual memory, processing speed, and planning function. This work sought for an interaction...

The development of musical skills by musicians results in specific structural and functional modifications in the brain. Surprisingly, no functional magnetic resonance imaging (fMRI) study has investigated the impact of musical training on brain function during long-term memory retrieval, a faculty particularly important in music. Thus, using fMRI,...
Article
Full-text available
Semantic memory has been investigated in numerous neuroimaging and clinical studies, most of which have used verbal or visual, but only very seldom, musical material. Clinical studies have suggested that there is a relative neural independence between verbal and musical semantic memory. In the present study, “musical semantic memory” is defined as...

Which is the degree of cognitive and functional independence between language and music? Since the end of the 19th century, the clinical observations in neuropsychology showed the existence of dissociations between the linguistic and the musical abilities. It is realistic to think that these two domains show common processes in their most simple ex...
Article
Full-text available
Numerous functional imaging studies have shown that retrieval from semantic and episodic memory is subserved by distinct neural networks. However, these results were essentially obtained with verbal and visuospatial material. The aim of this work was to determine the neural substrates underlying the semantic and episodic components of music using f...

For now well over a century, neuropsychologists have investigated the various components of auditory perception. The central disorders of this perception have been a topic of considerable interest, mainly through observations of auditory agnosia or amusia (selective loss of musical abilities). In a remarkable way, it was shown that the disorders of...

Article
The neuropsychological study of human memory is doubtless at the outset of the most important number of works of this discipline for more than 20 years. In this field, the specificity of the musical memory has few or not been studied. Thus, the idea of a relative perceptive independence between language and music is supported by numerous clinical a...
