Despite severe amnesia, some studies showed that Alzheimer Disease (AD) patients with moderate to severe dementia keep a consistent, but impoverished representation of themselves, showing preservation of the sense of identity even at severe stages of the illness. Some studies suggest that listening to music can facilitate the reminiscence of autobi...

Cognitive decline appears across aging. While some studies report beneficial effects of musical listening and practice on cognitive aging, the underlying neurobiological mechanisms remain unknown. This study aims to determine whether chronic (6 h/day, 3 times/week) and long-lasting (4-8 months) music exposure, initiated at middle age in rats (15 mo...
Article
Full-text available
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
Through this review of 25 clinical and experimental works on long-term musical memories in Alzheimer's disease (AD) patients, we attempt to clarify the conceptual understanding of musical memories, identify their evolution across the stages of the pathology, and propose possible explanations concerning the neural and cognitive mechanisms that under...

Research and care have improved a lot for persons with dementia (PWD) in France. However, most studies are essentially descriptive, and very few researches have focused on theoretical framework that may help understand and help their caregivers (CG). Yet, some approaches exist, and have proven to be efficient in other countries. The main interest o...

Prospective memory (PM) refers to the ability to remember to execute an intention at the appropriate moment in the future, which can be performed either at the appearance of an event (event-based, EBPM) or after a certain amount of time (time-based, TBPM). PM is generally impaired during aging but the cerebral substrates of this decline have been l...

Full-text available
The hippocampus has classically been associated with episodic memory, but is sometimes also recruited during semantic memory tasks, especially for the skilled exploration of familiar information. Cognitive control mechanisms guiding semantic memory search may benefit from the set of cognitive processes at stake during musical training. Here, we exa...
Article
Brain activity and structure are shaped by life experiences. This plasticity has often been demonstrated with different types of expertise by using functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). Experts showed domain-specific functional neural changes during completion of a task when compared to non-experts. However,...

Congenital amusia, a neuro-developmental disorder of music perception and production, has been associated to abnormal anatomical and functional connectivity in a right fronto-temporal pathway. To investigate whether spontaneous connectivity in brain networks involving the auditory cortex is altered in the amusic brain, we ran a seed-based connectiv...
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...

Full-text available
Prospective memory (PM) refers to the ability to remember to do something in the future, either in response to an event (event-based) or after a certain amount of time has elapsed (time-based). While the distinction between event- and time-based PM is widely acknowledged in the literature, little is known about the processes they share and those th...

Full-text available
The aim of this study was to explore whether musical practice-related gray matter increases in brain regions are accompanied by modifications in their resting-state functional connectivity. 16 young musically experienced adults and 17 matched nonmusicians underwent an anatomical magnetic resonance imaging (MRI) and a resting-state functional MRI (r...

Brain plasticity allows the central nervous system of a given organism to cope with environmental demands. Therefore, the quality of mental processes relies partly on the interaction between the brain's physiological maturation and individual daily experiences. In this review, we focus on the neural implementation of musical expertise at both an an...
Article
Full-text available
In Alzheimer patients with a solid musical background, isolated case-reports have reported the maintenance of remarkable musical abilities despite clear difficulties in their verbal memory and linguistic functions. These reports have encouraged a number of scientists to undertake more systematic studies which would allow a rigorous approach to the...
Article
Full-text available
Musical practice and cerebral plasticity: Can musical expertise prevent from cognitive aging? The intelligence of an organism expresses itself, in particular, by its ability to understand the environment and cope with its requests. This function is subserved by the high plastic properties of the brain where the anatomy of areas responsible for our...

Full-text available
Recognizing a musical excerpt without necessarily retrieving its title typically reflects the existence of a memory system dedicated to the retrieval of musical knowledge. The functional distinction between musical and verbal semantic memory has seldom been investigated. In this fMRI study, we directly compared the musical and verbal memory of 20 n...

Full-text available
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
Advances in functional neuroimaging studies have led to the need for improved anatomical precision to face with more and more specific challenges. Nevertheless, functional magnetic resonance imaging (MRI) (fMRI) suffers from geometrical distortions, which limit the matching between functional and anatomical data necessary to interpret fMRI results....
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...

Musical semantic memory: contribution of clinical neuropsychology and functional neuroimaging data Neuropsychological clinical dissociations between musical and linguistic skills in brain damage patients suggest the view of an autonomous musical semantic memory. On the basis of these clinical observations, Isabelle Peretz et al. propose the existen...
Article
Full-text available
Numerous functional imaging studies have examined the neural basis of semantic memory mainly using verbal and visuospatial materials. Musical material also allows an original way to explore semantic memory processes. We used PET imaging to determine the neural substrates that underlie musical semantic memory using different tasks and stimuli. The r...

This study aims to determine whether regular and long-lasting exposure of middle-aged Wistar rats (15 months) to music (6h per day, 3 times per week) can counterbalance the age-related cognitive impairment. Cognitive performances were assessed at start (before music exposure) and, then 4 and 9 months later. Some neurobiological markers involved are investigated.
