Unmarked Emotional States and the Affective Anchoring of Continuity
Sociological Forum, EarlyView.ABSTRACT Narratives around emotions often foreground remarkable episodes that interrupt situations, producing a “rollercoaster” image of emotional life that leaves its stability underdescribed. To analyze the emotional dimension of social continuity, this article theorizes unmarked emotional states (UES): culturally default, interactionally unobtrusive

Circadian and Seasonal effects on resting-state fMRI [PDF]
At temporal syklisitet er til stede i menneskelig fysiologi og kognisjon er allerede kjent. Det er imidlertid uklart i hvilken grad døgnrytmen og sesongmessige endringer påvirker den nevrale dynamikken. Denne oppgaven setter søkelys på de døgnvariasjoner

Perceptual Priors Update Contextual Feedback Processing in V1
Topics in Cognitive Science, EarlyView.Abstract Contextual information and prior knowledge facilitate perceptual processing, improving our recognition of even distorted or obstructed visual inputs. As a result, neuronal processing elicited by identical sensory inputs varies depending on the context in which we encounter those inputs.

Beyond the Adult Mind: A Developmental Framework for Predictive Processing in Infancy
Topics in Cognitive Science, EarlyView.Abstract Predictive Processing has been proposed as the single unifying computation underlying all of cognition, and proponents argue that all psychological phenomena can be explained as consequences of this principle. This theoretical framework has inspired many cognitive scientists and neuroscientists, but it currently has no developmental mechanism ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI
Experimental Physiology, EarlyView.Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Experimental Physiology, EarlyView.Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Experimental Physiology, EarlyView.Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes
