Rationale: Several studies have reported associations between substance use and effort-related decision making, or the degree to which effort expenditure impacts the choice between lower and higher value rewards. However, previous research has not explored effort-related decision making in populations with severe substance use disorder.
Objectives: Investigate the association between effort-related decision-making and substance use disorder severity.
Cognitive control enables us to translate our knowledge into actions, allowing us to flexibly adjust our behavior, according to environmental contexts, our internal goals, and future plans. Multimodal neuroimaging and neurostimulation techniques have proven essential for advancing our understanding of how cognitive control emerges from the coordination of distributed neuronal activities in the brain. In this review, we examine the literature on multimodal studies of cognitive control.

- Oats are a minor forage crop in Taiwan, and previous records of oat rust disease in the country are limited, leading to a lack of understanding of the pathogen population.
- In 2019, a rust-like outbreak at National Taiwan University's Experimental Farm prompted researchers to collect samples and identify the responsible pathogen, suspected to be the oat crown rust fungus.
- The study successfully confirmed the pathogen's identity using phenotypic and molecular techniques, establishing it as the first molecular confirmation of this pathogen in Taiwan and noting its low virulence traits.

- A study of six individuals who practiced Fire Kasina meditation reported high scores on mystical experience scales, comparable to those from high-dose psilocybin therapy.
- Participants described their experiences as extremely intense and reported significant changes in their worldview afterwards.
Cross-Frequency Coupling as a Biomarker for Early Stroke Recovery.
Neurorehabil Neural Repair
July 2024
Background: The application of neuroimaging-based biomarkers in stroke has enriched our understanding of post-stroke recovery mechanisms, including alterations in functional connectivity based on synchronous oscillatory activity across various cortical regions. Phase-amplitude coupling, a type of cross-frequency coupling, may provide additional mechanistic insight.
Objective: To determine how the phase of prefrontal cortex delta (1-3 Hz) oscillatory activity mediates the amplitude of motor cortex beta (13-20 Hz) oscillations in individual's early post-stroke.
