Sleep neuroimaging: Review and future directions

Journal of Sleep Research, EarlyView.
Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

EEG Brain Rhythms During Resting‐State Wakefulness and Sleep in Elderly Expert Meditators

Journal of Sleep Research, EarlyView.
Compared to controls, elderly expert meditators exhibited (1) more preserved resting‐state brain activity, (2) less altered sleep architecture, and (3) EEG features indicative of heightened cognitive states during NREM sleep. Importantly, several of the metrics that differed between groups also showed consistent correlations with meditation expertise ...

Sleep Slow Wave‐Bistability and the Connection Between the Sleeping Brain and the Environment—Neurobiological Considerations

Journal of Sleep Research, EarlyView.
Bistability is an inherent working mode of NREM sleep. Those bistable patterns ‐ sleep slow waves, K‐complexes, and the cyclic alternating pattern (on a longer, several seconds' time‐scale) ‐ have a double function; they protect sleep and provide an interface between the brain and the environment for information‐transfer during sleep.

In the End: Associations Between Sleep Disturbance and Functional Impairment in Fibromyalgia—A Path Analysis Study

Journal of Sleep Research, EarlyView.
ABSTRACT Fibromyalgia is a chronic pain condition characterised by widespread pain, sleep disturbances and mood disorders, often leading to significant functional impairment. Although sleep problems are recognised as important contributors to fibromyalgia symptoms, the mechanisms linking sleep disturbances, psychological factors and functional ...

Loneliness in schizophrenia: Just loneliness

Annals of the New York Academy of Sciences, EarlyView.
Loneliness may represent both a contributing cause and a consequence of schizophrenia. Studies have identified links between loneliness in schizophrenia and mistrust‐related cognitive biases, the functioning of brain areas involved in social perception, and poor physical health, which are similar to observations in non‐clinical, general population ...

Creativity in Music: The Brain Dynamics of Jazz Improvisation

Annals of the New York Academy of Sciences, EarlyView.
Using rest and task‐based fMRI, we studied brain dynamics in 16 jazz pianists under three conditions: playing a melody from memory (byHeart), improvising on melody (iMelody), and freely improvising on chord changes (iFreely). Increased improvisational freedom revealed greater note quantity and melodic entropy, and reduced pitch predictability.

Embodied Singing: Dual Role of Interoception in Vocal Expertise and Musical Competence

Annals of the New York Academy of Sciences, EarlyView.
ABSTRACT Musical expertise is often associated with heightened perceptual sensitivity to external sensory stimuli, yet its relationship with internal bodily awareness (interoception) remains elusive. This study examined whether interoceptive ability relates differentially to varying levels of singing expertise and investigated if interoception could ...

Posterior Cingulate Epilepsy: A Systematic Review

Journal of Clinical Neurophysiology, 2023
Summary: In this review, authors discuss epilepsy originating from posterior cingulate regions, a challenging entity to diagnose and most likely underrecognized. A systematic review of posterior middle and posterior cingulate epilepsy cases was conducted to present a summary of current knowledge about this localization-based type of epilepsy.

Posterior cingulate epilepsy: clinical and neurophysiological analysis [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2013
Posterior cingulate epilepsy (PCE) is misleading because the seizure onset is located in an anatomically deep and semiologically silent area. This type of epilepsy is rare and has not been well described yet. Knowledge of the characteristics of PCE is important for the interpretation of presurgical evaluation and better surgical strategy.

Voice recognition and the posterior cingulate: An fMRI study of prosopagnosia [PDF]

Journal of Neuropsychology, 2008
Voices, in addition to faces, enable person identification. Voice recognition has been shown to evoke a distributed network of brain regions that includes, in addition to the superior temporal sulcus (STS), the anterior temporal pole, fusiform face area (FFA), and posterior cingulate gyrus (pCG).
