A currently relevant issue in neurorehabilitation is how brain areas are reorganized during language recovery after brain damage. Previous studies (e.g. Crepaldi et al., 2011; Rofes et al., 2014) showed that the verb naming task has greater diagnostic value than the traditionally used noun naming. Some studies demonstrated activation of inferior frontal gyrus during fMRI naming verbs in healthy individuals (Berlingeri et al., 2008), as well as deficit in patients with lesions in this area (Rapp & Caramazza, 1997). In this study, we investigated functional cerebral reorganization of verb naming after intensive language therapy and its’ relation to brain lesion location using fMRI.

Motor imagery (MI) allows individuals to mentally simulate movements without execution, engaging neural pathways that overlap with those used during real actions. However, how imagery perspective influences corticospinal excitability across different effectors remains unclear. Using neuronavigated transcranial magnetic stimulation (TMS), we compared kinesthetic (KMI), first-person visual (VMI-1PP), and third-person visual (VMI-3PP) imagery of elbow flexion-extension ...

We present a multimodal dataset containing electroencephalography (EEG), electrocardiography (ECG), and video recordings from 49 participants. Each participant completed a single session lasting approximately 45 minutes. During each session they performed five tasks: resting state, inward concentration (focusing on the center of the forehead), outward concentration (visual search), and mind-wandering. EEG data were recorded from ...

Multidrug resistance (MDR) remains one of the principal challenges in cancer chemotherapy, necessitating new strategies to restore drug efficacy. In this study we developed and characterize a redox-responsive nanoplatform based on trithiocyanuric acid and polyethylene glycol (TTCA-PEG NPs) as a potential tool to overcome MDR and provide a biocompatible delivery system for conventional antitumor drugs. ...

Introduction:
While self-referential attention is thought to enhance interoceptive sensitivity, its effect on cardiac modulation of corticospinal excitability remains unexplored. This pilot study investigated how viewing one’s own face (self-face processing) modulates the cardiac-phase coupling of motor output and whether this heart-brain coupling depends on interoceptive accuracy (heartbeat perception).
Methods:
In 15 healthy adults, motor-evoked potentials (MEPs) were ...

Background: Neuroblastoma (NB), a transcriptionally driven pediatric malignancy, exhibits a remarkable clinical and biological heterogeneity. Two major subtypes, adrenergic and mesenchymal, are differentially governed by distinct subsets of transcription factors that constitute the core regulatory circuitry (CRC). The adrenergic subtype is often associated with MYCN amplification and is particularly aggressive and therapy-resistant, underscoring the need ...

Copper–organic compounds are being investigated as antitumor candidates. Besides their efficacy as cytotoxic agents alone, the oxidative potential of electrochemical Cu2+-to-Cu1+ transition emerges as an attractive approach for elimination of tumor cells otherwise resistant to chemotherapy. To minimize side effects of the potent oxidative burst upon Cu(II) reduction, the metal cations should be delivered to the ...
