The functional role of oscillatory dynamics in neocortical circuits: A computational perspective.

The dynamics of neuronal systems are characterized by hallmark features such as oscillations and synchrony. However, it has remained unclear whether these characteristics are epiphenomena or are exploited for computation. Due to the challenge of selectively interfering with oscillatory network dynamics in neuronal systems, we simulated recurrent networks of damped harmonic oscillators in which oscillatory activity is enforced in each node, a choice well supported by experimental findings.

Photosynthetic microbes have evolved and successfully adapted to the ever-changing environmental conditions in complex microhabitats throughout almost all ecosystems on Earth. In the absence of light, they can sustain their biological functionalities through aerobic respiration, and even in anoxic conditions through anaerobic metabolic activity. For a suspension of photosynthetic microbes in an anaerobic environment, individual cellular motility is directly controlled by its photosynthetic activity, i.

Social media is profoundly changing our society with its unprecedented spreading power. Due to the complexity of human behaviors and the diversity of massive messages, the information-spreading dynamics are complicated, and the reported mechanisms are different and even controversial. Based on data from mainstream social media platforms, including WeChat, Weibo, and Twitter, cumulatively encompassing a total of 7.

About one out of two diabetic patients develop diabetic neuropathy (DN), of these 20% experience neuropathic pain (NP) leading to individual, social, and health-economic burden. Risk factors for NP are largely unknown; however, premature aging was recently associated with several chronic pain disorders. DNA methylation-based biological age (DNAm) is associated with disease risk, morbidity, and mortality in different clinical settings.

Institute for Advancement of Community Health, Furman University, Greenville, SC, USA.
Objectives: To evaluate the implementation and sustainability of the effect of a 1-year Leadership in Education for Neurodevelopmental and related Disabilities (LEND) program in a southeastern state, and to examine its impact on advancing the Maternal Child Health Bureau's (MCHB) Blueprint for Change-a national agenda for pediatric healthcare reform.
Methods: This study applies the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework to rigorously evaluate LEND implementation and impact between 2018 and 2022. In-depth interviews (N = 24) were conducted among long-term (1-year) LEND trainees, via Zoom, in a southeastern state.
