Pain is a subjective experience with two complementary aspects: one is a localized sensation in a particular body part; the other is an unpleasant quality of varying severity commonly associated with behaviors directed at relieving or terminating the experience.
1 Νοε 2021 · Pain sensation leads to suffering via a cognitive (insula), emotional (ACC) and autonomic (ACC plus insula) processing, and is expressed as anger, fear, frustration, anxiety and depression, leading to changes in behaviour and functional disability. Acute pain transitions into chronic pain under influence of genetic and epigenetic factors.
Abstract. Pain is an integrative phenomenon that results from dynamic interactions between sensory and contextual (i.e., cognitive, emotional, and motivational) processes. In the brain the experience of pain is associated with neuronal oscillations and synchrony at different frequencies. However, an overarching framework for the significance of ...
24 Ιουλ 2023 · Nociceptive signal transduction to the brain is what elicits the perception of pain. The complex biopsychosocial phenomenon of pain occurs in the cortical and subcortical regions, such as the thalamus, amygdala, hypothalamus, periaqueductal grey, basal ganglia and areas of the cerebral cortex.
1 Οκτ 2022 · The experience of pain is a complex balance between nociception, the neural pathways transmitting noxious stimulus to the brain, signalling systems, modulation from higher centres and the unique perception of the individual.
10 Νοε 2021 · Given the known differential expression of δ and μ receptors in the brain’s pain pathways (35, 36), these results suggested that distinct circuits (and molecules in these circuits) control different nocifensive behaviors during the hotplate pain experience.
Painful stimuli are transduced by nociceptors into electrical and chemical signals, and transmitted from the periphery to the central nervous system, in a pathway called the ascending pain pathway or spinothalamic tract.
