Fun
Fun is defined by the ''Oxford English Dictionary'' as "light-hearted pleasure, enjoyment, or amusement; boisterous joviality or merrymaking; entertainment". Etymology and usage The word ''fun'' is associated with sports, entertaining media, high merriment, and amusement. Although its etymology is uncertain, it has been speculated that it may be derived from Middle English ' (fool) and ' (the one fooling the other). An 18th century meaning (still used in Orkney and Shetland) was "cheat, trick, hoax", a meaning still retained in the phrase "to make fun of". The way the word ''fun'' is used demonstrates its distinctive elusiveness and happiness. Expressions such as " Have fun!" and "That was fun!" indicate that fun is pleasant, personal, and to some extent unpredictable. Expressions such as "I was making fun of myself" convey the sense that fun is something that can be amusing and not to be taken seriously. The adjective "funny" has two meanings, which often need to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical, L-DOPA, which is synthesized in the brain and kidneys. Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. The brain includes several distinct dopamine pathways, one of which plays a major role in the motivational component of reward-motivated behavior. The anticipation of most types of rewards increases the level of dopamine in the brain, and many addictive drugs increase dopamine release or block its reuptake into neurons following release. Other brain dopamine pathways are involved in motor control and in controllin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hippocampus
The hippocampus (: hippocampi; via Latin from Ancient Greek, Greek , 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are components of the hippocampal formation located in the limbic system. The hippocampus plays important roles in the Memory consolidation, consolidation of information from short-term memory to long-term memory, and in spatial memory that enables Navigation#Navigation in spatial cognition, navigation. In humans, and other primates the hippocampus is located in the archicortex, one of the three regions of allocortex, in each cerebral hemisphere, hemisphere with direct neural projections to, and reciprocal indirect projections from the neocortex. The hippocampus, as the medial pallium, is a structure found in all vertebrates. In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of th ...

Amygdala
The amygdala (; : amygdalae or amygdalas; also '; Latin from Greek language, Greek, , ', 'almond', 'tonsil') is a paired nucleus (neuroanatomy), nuclear complex present in the Cerebral hemisphere, cerebral hemispheres of vertebrates. It is considered part of the limbic system. In Primate, primates, it is located lateral and medial, medially within the temporal lobes. It consists of many nuclei, each made up of further subnuclei. The subdivision most commonly made is into the Basolateral amygdala, basolateral, Central nucleus of the amygdala, central, cortical, and medial nuclei together with the intercalated cells of the amygdala, intercalated cell clusters. The amygdala has a primary role in the processing of memory, decision making, decision-making, and emotions, emotional responses (including fear, anxiety, and aggression). The amygdala was first identified and named by Karl Friedrich Burdach in 1822. Structure Thirteen Nucleus (neuroanatomy), nuclei have been identif ...

Time Flies When You're Having Fun
Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second, which is defined by measuring the electronic transition frequency of caesium atoms. General relativity is the primary framework for understanding how spacetime works. Through advances in both theoretical and experimental investigations of spacetime, it has been shown that time can be distorted and dilated, particularl ...

Marxism
Marxism is a political philosophy and method of socioeconomic analysis. It uses a dialectical and materialist interpretation of historical development, better known as historical materialism, to analyse class relations, social conflict, and social transformation. Marxism originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels. Marxism has developed over time into various branches and schools of thought, and as a result, there is no single, definitive " Marxist theory". Marxism has had a profound effect in shaping the modern world, with various left-wing and far-left political movements taking inspiration from it in varying local contexts. In addition to the various schools of thought, which emphasize or modify elements of classical Marxism, several Marxian concepts have been incorporated into an array of social theories. This has led to widely varying conclusions. Alongside Marx's critique of political economy, the defining cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entertainment
Entertainment is a form of activity that holds the attention and Interest (emotion), interest of an audience or gives pleasure and delight. It can be an idea or a task, but it is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things because individuals have different preferences, most forms of entertainment are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in Court (royal), royal courts, and developed into sophisticated forms over time, becoming available to all citizens. The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses private entertainment from a now enormous ...

Happiness
Happiness is a complex and multifaceted emotion that encompasses a range of positive feelings, from contentment to intense joy. It is often associated with positive life experiences, such as achieving goals, spending time with loved ones, or engaging in enjoyable activities. However, happiness can also arise spontaneously, without any apparent external cause. Happiness is closely linked to well-being and overall life satisfaction. Studies have shown that individuals who experience higher levels of happiness tend to have better physical and mental health, stronger social relationships, and greater resilience in the face of adversity. The pursuit of happiness has been a central theme in philosophy and psychology for centuries. While there is no single, universally accepted definition of happiness, it is generally understood to be a state of mind characterized by positive emotions, a sense of purpose, and a feeling of fulfillment. Definitions "Happiness" is subject to deb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
