Emotion, plasticity, context, and regulation: perspectives from affective neuroscience.
TLDR
The role of the prefrontal cortex (PFC) and amygdala in 2 broad approach-and withdrawal-related emotion systems is discussed in this paper, and implications of data showing experience-induced changes in the hippocampus for understanding psychopathology and stress-related symptoms are discussed.Abstract:
The authors present an overview of the neural bases of emotion. They underscore the role of the prefrontal cortex (PFC) and amygdala in 2 broad approach- and withdrawal-related emotion systems. Components and measures of affective style are identified. Emphasis is given to affective chronometry and a role for the PFC in this process is proposed. Plasticity in the central circuitry of emotion is considered, and implications of data showing experience-induced changes in the hippocampus for understanding psychopathology and stress-related symptoms are discussed. Two key forms of affective plasticity are described--context and regulation. A role for the hippocampus in context-dependent normal and dysfunctional emotional responding is proposed. Finally, implications of these data for understanding the impact on neural circuitry of interventions to promote positive affect and on mechanisms that govern health and disease are considered.read more

TL;DR: It is demonstrated that a short program in mindfulness meditation produces demonstrable effects on brain and immune function, and suggest that meditation may change brain andimmune function in positive ways and underscore the need for additional research.

How Does Mindfulness Meditation Work? Proposing Mechanisms of Action From a Conceptual and Neural Perspective
TL;DR: Several components through which mindfulness meditation exerts its effects are explored, suggesting that the mechanisms described here work synergistically, establishing a process of enhanced self-regulation.

Emotion and motivation I: defensive and appetitive reactions in picture processing.
TL;DR: The findings suggest that affective responses serve different functions-mobilization for action, attention, and social communication-and reflect the motivational system that is engaged, its intensity of activation, and the specific emotional context.

Does Positive Affect Influence Health
Sarah D. Pressman,Sheldon Cohen +1 more
TL;DR: This review highlights consistent patterns in the literature associating positive affect (PA) and physical health and raises serious conceptual and methodological reservations, but suggests an association of trait PA and lower morbidity and of state and traitPA and decreased symptoms and pain.

TL;DR: It is shown that the full set of hydromagnetic equations admit five more integrals, besides the energy integral, if dissipative processes are absent, which made it possible to formulate a variational principle for the force-free magnetic fields.

Development and validation of brief measures of positive and negative affect: The PANAS scales.
TL;DR: Two 10-item mood scales that comprise the Positive and Negative Affect Schedule (PANAS) are developed and are shown to be highly internally consistent, largely uncorrelated, and stable at appropriate levels over a 2-month time period.

TL;DR: For instance, the authors discusses the multiplicity of the consciousness of self in the form of the stream of thought and the perception of space in the human brain, which is the basis for our work.
