Exposure to ionizing radiation during manned deep space missions to Mars could lead to functional impairments of the central nervous system, which may compromise the success of the mission and affect the quality of life for returning astronauts. Along with radiation-induced changes in cognitive abilities and emotional status, the effects of increased motor activity were observed. The mechanisms behind these phenomena still remain unresolved.

Parkinson's disease (PD) is a progressive disease that requires effective staging management. The role of intestinal microbiota in PD has been studied, but its changes at different stages are not clear. In this study, meta- analysis, bioinformatics analysis and in vivo simulation were used to explore the intestinal microbiota distribution of PD patients and models at different stages.

Trans-active response DNA-binding protein-43 (TDP-43) is the major pathological protein in motor neuron disease and TDP-43 pathology has been described in the brains of up to 50% of patients with Alzheimer disease (AD). Hippocampal sclerosis of aging (HS-A), an age-related neuropathology characterized by severe neuronal loss and gliosis in CA1 and/or subiculum, is found in ∼80% of cases that are positive for phosphorylated TDP-43. HS-A is seen as a co-pathology in cases with AD, limbic-predominant age-related TDP-43 encephalopathy neuropathologic changes (LATE-NC), and frontotemporal degeneration.

Introduction: Parkinson's disease (PD) is a common neurodegenerative disease. Glucagon-Like-Peptide-1 (GLP-1) receptor agonists decrease the incidence of developing PD, and are being considered for the treatment of PD.
Areas Covered: A phase 2 clinical trial of lixisenatide, a GLP-1 receptor agonist, in the early stages of PD.
Event-related theta synchronization over sensorimotor areas differs between younger and older adults and is related to bimanual motor control.

When engaged in dynamic or continuous movements, action initiation involves modifying an ongoing motor program rather than initiating it from rest. Event-related theta synchronization over sensorimotor areas is a neurophysiological marker for modifying motor programs. We used electroencephalography (EEG) to examine how task complexity and age affect event-related synchronization (ERS) in the theta band during a dynamic bimanual, visuomotor pinch force task.
