Background: Noninvasive brain stimulation can modulate neural processing within the motor cortex and thereby might be beneficial in the rehabilitation of hemispatial neglect after stroke.
Methods: We review the pertinent literature regarding the use of transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation in order to facilitate recovery of hemispatial neglect after stroke.
Results: Twenty controlled trials (including 443 stroke patients) matched our inclusion criteria. Methodology and results of each study are presented in a comparative approach. Current data seem to indicate a better efficiency of repetitive transcranial magnetic stimulation, compared to tDCS to ameliorate hemispatial neglect after stroke.
Conclusions: Noninvasive brain stimulation has the potential to facilitate recovery of hemispatial neglect after stroke, but until today, there are not enough data to claim its routine use.

EXPRESS: The Time Course of Cognitive Effort During Disrupted Speech.

Listeners often find themselves in scenarios where speech is disrupted, misperceived, or otherwise difficult to recognize. In these situations, many individuals report exerting additional effort to understand speech, even when repairing speech may be difficult or impossible. This investigation aimed to characterize cognitive effort across time during both sentence listening and a post-sentence retention interval by observing the pupillary response of participants with normal to borderline normal hearing in response to two interrupted speech conditions: sentences interrupted by gaps of silence or bursts of noise.

Sleep is essential to human health, yet 27% of the global population suffers from sleep issues, which often lead to fatigue, depression, and impaired cognitive function. While pharmacological treatments exist, non-pharmacological approaches like music therapy have shown promise in enhancing sleep quality. This review, analyzing 27 studies with various experimental paradigms, confirms that music therapy significantly improves subjective sleep quality, largely by alleviating anxiety and regulating mood through perceptual pathways.

A 69-year-old right-handed man, who initially suffered a stroke 8 years ago and experienced two recurrences since then, presented with right hemiplegia and left hemispatial neglect as a post-stroke syndrome in the chronic phase. This report demonstrates the use of active musical instrument playing with Musical Neglect Training (MNT®) to improve severe left-side neglect and activities of daily living (ADLs). In addition to physical and occupational therapy, individual MNT® was incorporated into the patient's rehabilitation plan to improve his hemispatial neglect.

Charles Bonnet syndrome (CBS) is a clinical condition in which patients with visual impairment experience visual hallucinations (VH) in the presence of clear consciousness. It typically occurs in elderly people and confuses clinicians with multiple differential diagnoses due to VH, which can be present in a variety of clinical conditions ranging from psychosis to neurocognitive disorders (eg, neurocognitive disorder with Lewy bodies). In the latter, the concomitant presence of cognitive decline and parkinsonism aids the diagnosis.

Research over the past two decades has documented the importance of sleep to language learning. Sleep has been suggested to play a role in establishing new speech representations as well; however, the neural mechanisms corresponding to sleep-mediated effects on speech perception behavior are unknown. In this study, we trained monolingual English-speaking adults to perceive differences between the Hindi dental vs.
