Cortical preparation for movement is reflected in the readiness potential (RP) waveform preceding voluntary limb movements. In the case of oral movements, the RP may be affected by the complexity or linguistic nature of the tasks. In this experiment, EEG potentials before a nonspeech task (lip pursing), a speech-like task (lip rounding), and single word production were recorded from scalp electrodes placed at the cranial vertex (Cz) and over the left and right motor strips (C3′ and C4′). Seven right-handed female subjects produced at least 70 repetitions of the three tasks, in each of five repeated sessions. EEG records were averaged with respect to EMG onset at the lip. The word task, as opposed to the other tasks, was associated with greater negative amplitude in the RP waveform at the vertex site. Differences between the waveforms recorded at the rightand left-hemisphere sites were insignificant. Although intersubject variability was high, individuals had relatively stable patterns of response across sessions. Results suggest that the RP recorded at the vertex site is sensitive to changes in task complexity. The RP did not reflect lateralized activity indicative of hemispheric dominance.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.

Abstract. Words whose articulation resembles ingestion movements are preferred to words mimicking expectoration movements. This so-called in-out effect, suggesting that the oral movements caused by consonantal articulation automatically activate concordant motivational states, was already replicated in languages belonging to Germanic (e.g., German and English) and Italic (e.g., Portuguese) branches of the Indo-European family. However, it remains unknown whether such preference extends to the Indo-European branches whose writing system is based on the Cyrillic rather than Latin alphabet (e.g., Ukrainian), or whether it occurs in languages not belonging to the Indo-European family (e.g., Turkish). We replicated the in-out effect in two high-powered experiments ( N = 274), with Ukrainian and Turkish native speakers, further supporting an embodied explanation for this intriguing preference.

Objective. Conduct a comparative analysis of clinical and neurosonographic indicators of intracranial hemorrhage in infants.Materials and methods. In the clinical part of the study, 68 patients took part in the acute / acute periods of intracranial hemorrhage, which we took for the study on the basis of the Tashkent City Children's Clinical Hospital No1. Gender ratios of which were 69.1% boys (47 children) and 30.9% girls (21 children), from birth to 2 months of life (average age at the time of hemorrhage is 36.28 ± 9.85 days). Diagnostic examination included neurosonography (NSG) of all children in the first 24 hours of the implementation of intracranial hemorrhages on admission to the clinic.Results. According to our study of 68 children with intracranial hemorrhage, it turned out that the average age of morbidity was 36.28 ± 9.85 days (p < 0.001) Neurosonographic indicators stated the presence of parenchymal hemorrhage (right and left hemisphere), SAH (subarachnoid hemorrhage), hemorrhage into the trunk, IVH (intraventricular hemorrhage) II, IVH III. According to neurosonography, parenchymal hemorrhage (right-16 or left hemisphere-21) was observed in 37 patients, SAH and IVH-II 21 (30.9%) patients, IVH III – in 17 (25%) patients, hemorrhage in 3 (4.4%) brain stem of patientsConclusion. Analysis of the implementation of hemorrhage showed that not always small gestational age is the risk of hemorrhage. Cases of less severe changes (27%) on NSG with a coarser clinical picture and vice versa (15%), necessitate (taking into account the severity of the neurological state), a more detailed examination, including visualization (CT, MRI).
