The lower urinary tract's main functions are storage and elimination. The micturition reflex pathway is modulated by the spinobulbospinal reflex pathway as well as higher brain centers involved in the voluntary micturition control. Micturition is sensitive to numerous injuries, resulting in various types of dysfunction. Animal studies indicate that lower urinary tract dysfunction partly depends on plasticity of the neural pathways. Reflex plasticity is associated with changes in ion channels, receptors, and numerous mediators...

Patients with Parkinson's disease (PD) may develop a wide spectrum of non-motor symptoms during the course of illness. Psychosis is one such commonly observed non-motor symptoms of PD. Although several studies based on neuroimaging, genetics, retinal imaging, and neuropsychological evaluations have explored the pathogenesis of psychosis in PD; exact neural correlates are yet to be understood. Identification of factors related to psychosis in PD is important, as psychosis has been reported to be associated with higher rates of mortality, caregiver distress, and nursing home placements...

Recent work has stimulated interest in the use of exosomes as nanocarriers for delivery of small drugs, RNAs, and proteins to the central nervous system (CNS). To overcome the blood-brain barrier (BBB), exosomes were modified with brain homing peptides that target brain endothelium but likely to increase immune response. Here for the first time we demonstrate that there is no need for such modification to penetrate the BBB in mammals. The naïve macrophage (Mϕ) exosomes can utilize, 1) on the one hand, the integrin lymphocyte function-associated antigen 1 (LFA-1) and intercellular adhesion molecule 1 (ICAM-1), and, 2) on the other hand, the carbohydrate-binding C-type lectin receptors, to interact with brain microvessel endothelial cells comprising the BBB...

How the brain reconstitutes consciousness and cognition after a major perturbation like general anesthesia is an important question with significant neuroscientific and clinical implications. Recent empirical studies in animals and humans suggest that the recovery of consciousness after anesthesia is not random but ordered. Emergence patterns have been classified as progressive and abrupt transitions from anesthesia to consciousness, with associated differences in duration and electroencephalogram (EEG) properties...

BACKGROUND: Emergence delirium is defined as a cognitive disturbance during emergence from general anesthesia resulting in hallucinations, delusions and confusion manifested by agitation, restlessness, involuntary physical movement and extreme flailing in bed. Postoperative emergence delirium develops in 12% to 18% of all children undergoing general anesthesia for surgery. This post-anesthetic phenomenon changes cognitive and psychomotor behavior, and puts pediatric patients and health care personnel at risk of injury...

Infection with Zika virus (ZIKV) during pregnancy may cause severe developmental defects in the human brain via unknown mechanisms. In a recent issue of Science, Chavali et al. (2017) identified a neural progenitor cell (NPC)-specific RNA binding protein that may underlie the high levels of ZIKV replication and apoptosis observed in these cells during congenital infections.

Reductive art is a term to describe an artistic style or an aesthetic, rather than an art movement. It is stripping down as a new way of seeing. Movements and other terms that are sometimes associated with reductive art include abstract art, minimalism, ABC art, anti-illusionism, cool art, and rejective art. Eric Kandel's fifth book focuses on reductionism as the principle guiding an ongoing dialogue between the worlds of science and art.

Monkey vocal tracts are capable of producing monkey speech, not the full range of articulate human speech. The evolution of human speech entailed both anatomy and brains. Fitch, de Boer, Mathur, and Ghazanfar in Science Advances claim that "monkey vocal tracts are speech-ready," and conclude that "…the evolution of human speech capabilities required neural change rather than modifications of vocal anatomy." Neither premise is consistent either with the data presented and the conclusions reached by de Boer and Fitch themselves in their own published papers on the role of anatomy in the evolution of human speech or with the body of independent studies published since the 1950s...

Although music performance has been widely studied in the behavioural sciences, less work has addressed the underlying neural mechanisms, perhaps due to technical difficulties in acquiring high-quality neural data during tasks requiring natural motion. The advent of wireless electroencephalography (EEG) presents a solution to this problem by allowing for neural measurement with minimal motion artefacts. In the current study, we provide the first validation of a mobile wireless EEG system for capturing the neural dynamics associated with piano performance...

Gaining a better understanding of the human brain continues to be one of the greatest challenges for science, largely because of the overwhelming complexity of the brain and the difficulty of analyzing the features and behavior of dense neural networks. Regarding analysis, 3D visualization has proven to be a useful tool for the evaluation of complex systems. However, the large number of neurons in non-trivial circuits, together with their intricate geometry, makes the visualization of a neuronal scenario an extremely challenging computational problem...

Loved for his empathetic nature but admired for his analytical mind, Gaspar Spurzheim (1776-1832) was a prominent contributor to phrenology, a field of neuroscience focused on studying the shapes of the skulls in relation to the activity levels of certain functional areas of the brain. This curiosity about the connection between physical characteristics and brain function was seeded in the young mind of Spurzheim when he observed that classmates with seemingly superb memories also appeared to have bright eyes...

The use of 'brain training' games is often regarded as relating to wider ideals of self-improvement and youthfulness. Hence, use is intertwined with discourses of 'active' ageing. This paper analyzes how the use and users of brain training games were configured in the UK media, from 2005 to 2015, and examines how notions of active ageing relate to these representations. Game users were rarely constructed solely as gamers, and were more often presented as prudent individuals focused on a serious goal. This configuration related to assumed and enjoined motivations for brain training; specifically, users were commonly framed as seeking to enhance cognition and limit/delay cognitive decline...

OBJECTIVE Deep brain stimulation (DBS) is effective in the management of patients with advanced Parkinson's disease (PD). While both the globus pallidus pars interna (GPi) and the subthalamic nucleus (STN) are accepted targets, their relative efficacy in randomized controlled trials (RCTs) has not been established beyond 12 months. The objective of this study was to conduct a meta-analysis of RCTs to compare outcomes among adults with PD undergoing DBS of GPi or STN at various time points, including 36 months of follow-up...
