Homeostatic Emotion
Homeostatic feeling is a class of feelings (e.g. thirst, fatigue, pain, desire, malaise, well-being) that inform us about our physiological condition. In his earlier work Antonio Damasio used "primordial feeling" but he now prefers the term "homeostatic feeling" for the class. Affective neuroscientist, Jaak Panksepp, identified homeostatic feeling as one of three primary classes of affect: *homeostatic affect: e.g., thirst, fatigue *sensory affect: e.g., touch, warmth *emotional affect: e.g., anger, fear. Some homeostatic feelings motivate specific behavior aimed at maintaining the body in its ideal state. For example, hunger motivates eating, fatigue motivates resting and hyperthermia motivates stepping into the shade. Neuroscientist Derek Denton called these ''motivating'' homeostatic feelings "primordial emotions" and defined them as "the subjective element of the instincts, which are the genetically programmed behaviour patterns which contrive homeostasis. They include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonio Damasio
Antonio Damasio (; born 25 February 1944) is a Portuguese neuroscientist. He is currently the David Dornsife Chair in Neuroscience, as well as Professor of Psychology, Philosophy, and Neurology, at the University of Southern California, and, additionally, an adjunct professor at the Salk Institute. He was previously the chair of neurology at the University of Iowa for 20 years.

Damasio's research in neuroscience has shown that emotions play a central role in social cognition and decision-making. Life and work During the 1960s, "Damasio studied medicine at the University of Lisbon Medical School, where he also did his neurological residency and completed his doctorate in 1974." "For part of his studies, he researched behavioral neurology under the supervision of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaak Panksepp
Jaak Panksepp (June 5, 1943 – April 18, 2017) was an Estonian-American neuroscientist and psychobiologist who coined the term "affective neuroscience", the name for the field that studies the neural mechanisms of emotion. He was the Baily Endowed Chair of Animal Well-Being Science for the Department of Veterinary and Comparative Anatomy, Pharmacology, and Physiology at Washington State University's College of Veterinary Medicine, and Emeritus Professor of the Department of Psychology at Bowling Green State University. He was known in the popular press for his research on laughter in non-human animals. Early life and education Panksepp was born in Tartu, Estonia on June 5, 1943. His family escaped the ravages of post-WWII Soviet occupation by moving to the United States when he was very young. He initially studied at University of Pittsburgh in 1964, and then completed a Ph.D. at the University of Massachusetts. Research Panksepp resisted establishment forces in animal rese ...

Affect (psychology)
Affect, in psychology, is the underlying experience of feeling, emotion, attachment theory, attachment, or Mood (psychology), mood. It encompasses a wide range of emotional states and can be positive (e.g., happiness, joy, excitement) or negative (e.g., sadness, anger, fear, disgust). Affect is a fundamental aspect of human experience and plays a central role in many psychological theories and studies. It can be understood as a combination of three components: emotion, mood (enduring, less intense emotional states that are not necessarily tied to a specific event), and affectivity (an individual's overall disposition or temperament, which can be characterized as having a generally positive or negative affect). In psychology, the term ''affect'' is often used interchangeably with several related terms and concepts, though each term may have slightly different nuances. These terms encompass: emotion, feeling, mood, emotional state, sentiment, affective state, emotional response, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep In The Shade - Geograph
Sheep (: sheep) or domestic sheep (''Ovis aries'') are a domesticated, ruminant mammal typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' ( ), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat ( lamb, hogget or mutton), and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derek Denton
Derek Ashworth Denton (27 May 1924 – 18 November 2022) was an Australian scientist who elucidated the regulation of electrolytes in extracellular fluid, the hormones controlling this regulation, particularly aldosterone, and the instinctive behaviours controlling intake of water and salts. He was cited in 1995 at election to the U.S. National Academy of Sciences as the world’s leading authority on the regulation of salt and water metabolism and relevant endocrine control mechanisms. He was one of Australia’s most eminent scientists. Career Denton was the founding Director and Emeritus Director of the Howard Florey Institute, Honorary Professor at the University of Melbourne and a consultant at the Baker Research Institute. Denton's last book is '' The Primordial Emotions: The Dawning of Consciousness''. Research Three months after medical graduation in 1947, he made a basic discovery on kidney function at the Royal Melbourne Hospital. In the face of profuse alkaline ...

Human Homeostasis
In biology, homeostasis (British English, British also homoeostasis; ) is the state of steady internal physics, physical and chemistry, chemical conditions maintained by organism, living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium, and calcium ions, as well as the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life. Homeostasis is brought about by a natural resistance to change when already in optimal conditions, and equilibrium is maintained by many regulatory mechanisms; it is thought to be the central motivation for all organic action. All home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Simian
The simians, anthropoids, or higher primates are an infraorder (Simiiformes ) of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders New World monkey, Platyrrhini (New World monkeys) and Catarrhini, the latter of which consists of the family Cercopithecidae (Old World monkeys in the stricter sense) and the superfamily Hominoidea (apesincluding humans). The simians are sister group to the Tarsiiformes, tarsiers (Tarsiiformes), together forming the Haplorhini, haplorhines. The Evolutionary radiation, radiation occurred about 60 million years ago (during the Cenozoic era); 40 million years ago, simians colonized South America, giving rise to the New World monkeys. The remaining simians (catarrhines) split about 25 million years ago into Old World monkey, Cercopithecidae and apes (including humans). Taxonomy In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insular Cortex
The insular cortex (also insula and insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal lobe, parietal and frontal lobes) within each brain hemisphere, hemisphere of the mammalian brain. The insulae are believed to be involved in consciousness and play a role in diverse functions usually linked to emotion or the regulation of the body's homeostasis. These functions include compassion, empathy, taste, perception, motor control, self-awareness, cognitive functioning, interpersonal relationships, and awareness of homeostatic emotions such as Hunger (physiology), hunger, pain and fatigue. In relation to these, it is involved in psychopathology. The insular cortex is divided by the central sulcus of the insula, into two parts: the anterior insula and the posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterior Cingulate Cortex
In human brains, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33. It is involved in certain higher-level functions, such as attention allocation, reward anticipation, decision-making, impulse control (e.g. performance monitoring and error detection), and emotion. Some research calls it the anterior midcingulate cortex (aMCC). Anatomy The anterior cingulate cortex can be divided anatomically based on cognitive (dorsal), and emotional ( ventral) components. The dorsal part of the ACC is connected with the prefrontal cortex and parietal cortex, as well as the motor system and the frontal eye fields, making it a central station for processing top-down and bottom-up stimuli and assigning appropriate control to other areas in the brain. By contrast, the ventral part of the ACC is connected with the amygdala, nucleu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerald Edelman
Gerald Maurice Edelman (; July 1, 1929 – May 17, 2014) was an American biologist who shared the 1972 Nobel Prize in Physiology or Medicine for work with Rodney Robert Porter on the immune system. Edelman's Nobel Prize-winning research concerned discovery of the structure of antibody molecules.Structural differences among antibodies of different specificities by G. M. Edelman, B. Benacerraf, Z. Ovary and M. D. Poulik in ''Proc Natl Acad Sci U S A'' (1961) volume 47, pages 1751-1758. In interviews, he has said that the way the components of the immune system evolve over the life of the individual is analogous to the way the components of the brain evolve in a lifetime. There is a continuity in this way between his work on the immune system, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
