Summary
Long-term Transcendental Meditation practitioners show unique brain blood flow patterns. During meditation, attention areas had higher blood flow, while arousal areas had lower blood flow, suggesting effortless focus.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Meditation Research
Background:
- Transcendental Meditation (TM) is a widely practiced meditation technique.
- Understanding the neural mechanisms of TM is crucial for its application in mental well-being.
- Previous research has explored TM's effects, but detailed blood flow patterns during practice require further investigation.
Purpose of the Study:
- To investigate the blood flow patterns in the brains of long-term Transcendental Meditation practitioners during meditation.
- To identify specific brain regions affected by TM practice and characterize the nature of these changes.
Main Methods:
- Within-group design study.
- Functional Magnetic Resonance Imaging (fMRI) was used to measure blood flow.
- 16 long-term TM practitioners (mean 34.3 years, >36,000 hours practice) were studied.
Main Results:
- Significantly higher blood flow was observed in executive and attention areas (anterior cingulate and dorsolateral prefrontal cortices) during TM.
- Significantly lower blood flow was observed in arousal areas (pons and cerebellum) during TM.
- This pattern suggests an effortless attentional state during TM, distinct from other meditation practices.
Conclusions:
- The observed blood flow pattern in TM practitioners supports the notion of minimal effort during practice.
- TM uniquely engages attentional systems while reducing arousal system activity.
- Future research should compare blood flow patterns across different meditation techniques within the same study.

A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

01:28Equivalent Circuits for Practical Transformers
1.4K
The practical equivalent circuits of single-phase two-winding transformers exhibit significant deviations from their idealized versions due to the inherent properties of winding resistance and finite core permeability. These properties result in real and reactive power losses, affecting the transformer's performance. Understanding these deviations is crucial for designing more efficient transformers.
In a practical transformer, each winding exhibits resistance and leakage reactance. The...

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

01:24pH
146.2K
The potential of hydrogen (pH) is a measure of the acidity or basicity of a water-based solution determined by the concentration of hydronium ions (H3O+). In one liter of pure water at neutral pH, there are 1×10−7 moles of hydronium ions. However, the extensive range of hydronium ion concentrations present in water-based solutions makes measuring pH in moles cumbersome. Therefore, a pH scale was developed to convert moles of hydronium ions into the negative logarithm of the hydronium...
