Age- and sex-related oculomotor manifestation of dopamine deficiency in Segawa disease
CONCLUSIONS: The findings can be explained by a dysfunction of the BG-direct pathway impinging on superior colliculus (SC) due to dopamine deficiency. The disturbed inhibitory control of saccades may be explained by increased SC responsivity to visual stimuli.SIGNIFICANCE: Oculomotor abnormalities in SD can be explained by dysfunction of the BG inhibitory pathways reaching SC, with a delayed maturation in male SD patients, consistent with previous pathological/physiological studies.PMID:38064930 | DOI:10.1016/j.clinph.2023.11.010 (Source: Clinical Neurophysiology)

Aberrant hyperfocusing in schizophrenia indicated by elevated theta phase-gamma amplitude coupling
CONCLUSIONS: Aberrant hyperfocusing, as reflected by elevated TGC in attention-related brain regions, was related to behavioral performance on the TMT-A/B in schizophrenia patients.SIGNIFICANCE: This study suggests that TGC is a electrophysiological marker for aberrant hyperfocusing of attentional processes that may result in cognitive impairments in schizophrenia patients.PMID:38064931 | DOI:10.1016/j.clinph.2023.11.012 (Source: Clinical Neurophysiology)

Sensory event-related potential morphology predicts age in premature infants
CONCLUSIONS: Sensory-evoked potentials are predictive of age in premature infants and brain age deviations are related to biologically and clinically meaningful individual differences in nervous system maturation.SIGNIFICANCE: This model could be used to detect abnormal development of infants' response to sensory stimuli in their environment and may be predictive of neurodevelopmental outcome.PMID:38064929 | DOI:10.1016/j.clinph.2023.11.007 (Source: Clinical Neurophysiology)

Transcranial direct current stimulation of the right temporoparietal junction facilitates hippocampal spatial learning in Alzheimer's disease and mild cognitive impairment
CONCLUSIONS: These results suggest that tDCS can facilitate spatial memory consolidation via stimulating the parietal-hippocampal navigation network in AD and MCI patients.SIGNIFICANCE: Our findings suggest that tDCS of the temporoparietal junction may restore spatial navigation and memory deficits in patients with AD and MCI.PMID:38056370 | DOI:10.1016/j.clinph.2023.11.003 (Source: Clinical Neurophysiology)

Hippocampal barques and their manifestation as 14 & amp;6 Hz positive spikes during sleep
CONCLUSIONS: Hippocampal barques are predominant in NREM II and SWS, and tend to increase their presence during SWS. Their scalp manifestation as 14&6/sec positive spikes is confounded by wakefulness, REM and NREM I stages, and "masked" by the co-occurrence of NREM II and SWS slow waves, and overlapping reactive micro-arousal elements.SIGNIFICANCE: Our study highlighted the overnight profile of hippocampal barques, in relation to the respective profile of their scalp manifestation, the 14&6/sec positive spikes variant.PMID:38042011 | DOI:10.1016/j.clinph.2023.11.008 (Source: Clinical Neurophysiology)
