Professional burnout is a syndrome that is characterized by psychophysical or emotional exhaustion, depersonalization and diminished professional efficacy. Research on burnout often indicates deficits in cognitive functioning, such as memory problems or impaired voluntary control over attention. Many studies focus on behavioral and self-reported measures of burnout consequences; however, a limited number have focused on its consequences on a neural level. In our EEG study (N = 88; 42 with burnout), we analyzed the event-related potentials (ERP) associated with stimulus, response and feedback processing using two experimental procedures - the Go/NoGo Task and the Doors Task. Our results show that while there is no difference in performance between burnout and control group, on the neural level there are significant differences in all analyzed aspects of information processing: stimulus, response and feedback processing, indicated by the N200 and P300, Pe, and P200 event-related potentials, respectively.

Nanomaterials with unparalleled physical and chemical attributes have become a cornerstone in the field of nanomedicine delivery. These materials can be engineered into various functionalized nanocarriers, which have become the focus of research. Stimulus-responsive nanodrug delivery systems (SRDDS) stand out as a sophisticated class of nanocarriers that can release drugs in response to environmental cues.

Background: Electrically evoked compound action potential (ECAP) can be used to measure the auditory nerve's response to electrical stimulation in cochlear implant (CI) users. In the Nurotron CI system, extracting the ECAP waveform from the stimulus artifact is time-consuming.
Method: We developed a new paradigm ("FastCAP") for use with Nurotron CI devices.

Background: It is known that illicit and prescribed drugs impact pupil size, eye movement and function. Still, comprehensive quantitative evaluations under known ambient light conditions are lacking, when smartphones are used for monitoring.
Methods: In this clinical study (NCT05731999), four medicinal products with addiction risks were administered to 48 subjects (18-70 years old, all with informed consent, 12 subjects per drug).

In everyday hearing, listeners face the challenge of understanding behaviorally relevant foreground stimuli (speech, vocalizations) in complex backgrounds (environmental, mechanical noise). Prior studies have shown that high-order areas of human auditory cortex (AC) pre-attentively form an enhanced representation of foreground stimuli in the presence of background noise. This enhancement requires identifying and grouping the features that comprise the background so they can be removed from the foreground representation.

In nature, animals can realize multimodal movements such as walking, climbing, and jumping through transformation in locomotor gaits or form for survival, which is highly desired for untethered flexible actuators yet remains challenging. Here, we propose a robust self-healing multimodal actuator enabled by noncovalent assembled nanostructures with elaborate regulation of multistage responsive behaviors. Owing to the dynamic interfacial design between multiple components, the stimulus can be accurately delivered through a "light-heat-force release" pathway, endowing the actuator with diverse motion capabilities and desired jumping ability (27 cm, 34 times body length).
