The auCMS demonstrated consistent efficacy, with animals subjected to automated stressors displaying similar responses to those exposed to conventional manual methods, thus confirming its validity as a reliable tool. While some stressors still require human involvement, the automation of key processes has markedly enhanced efficiency and minimized operational time.

The studies included in this review point towards certain brain regions that are shared among creativity and affective control, such as the prefrontal cortex, the anterior cingulate cortex, the dorsolateral prefrontal cortex, the medial temporal lobe and the inferior parietal lobule. The common neural networks of emotion regulation and creativity mainly focus on the default mode, the executive control and the salience networks.

Lifestyle patterns, including elevated blood pressure, weight, glucose levels, air pollution exposure, smoking, and nutrition, contribute to stroke risk. Stroke's impact on the brain's functional and structural integrity leads to cognitive deficits and challenges in daily activities. Rehabilitation is crucial for functional recovery. This review explores the association between brain networks and behavioral deficits post-stroke, aiming to establish a cartographic approach for predicting rehabilitation outcomes. Methodologically, a systematic review following PRISMA-ScR guidelines was conducted, searching PUBMED and SCOPUS for relevant studies from 2003 to 2023. The synthesis of 29 studies reveals insights into language, comprehension, general cognition, praxis, and complex cognitive abilities after stroke. Language recovery involves networks like the presupplementary motor area, Default Mode Network, and sensorimotor integration. Comprehension deficits result from focal lesions and left hemisphere stroke, with connectivity training showing potential. General cognition studies emphasize the role of working memory, connectivity patterns predicting ischemic attacks, and cognitive impairment post-subtentorial strokes. Praxis studies highlight the importance of spared left hemisphere regions, interhemispheric connectivity, and cognitive mechanisms in complex figure copying tasks. The intricate relationship between complex cognitive abilities and brain networks is explored, revealing the impact of damage on verbal creativity, mental state judgments, affordance-based processing, and beta-band phase synchronization in memory retrieval. Strengths include a systematic search strategy and inclusion of original English studies. Limitations include the lack of statistical analysis due to heterogeneity and varying methodologies. The synthesis underscores the shift toward understanding brain function through network perspectives, combining neuroimaging with neuropsychological assessments.

We specifically used this model to examine the potential of 17β-estradiol (E2), which is considered to be neuroprotective, to influence injury-induced events, such as astrocyte and microglia activation, and to reduce cell death, if applied acutely after TBI. We found that established consequences of mechanical brain injury are replicated in the model, as increased apoptosis was observed 8 h and PI-uptake was significantly enhanced 24 h after <em>in vitro</em> TBI in CA1 pyramidal layer. GFAP expression was not overall increased, but correlated with cell death, indicating a confined activation of astrocytes associated with cell injury. Similarly, no general increase of microglia was detected, but activated microglia was observed in the vicinity of dying cells. Notably, application of E2 (20 nM) increased GFAP expression after 48 h, but did not significantly reduce cell death at any of the studied time points. We conclude that the presented <em>in vitro</em> TBI model is generally suited to study processes triggered by diffuse mechanical forces acting on brain tissue.
