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 cla ... [...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. Dopamine constitutes about 80% of the catecholamine content in the brain. 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. Neurotransmitters are synthesized in specific regions of the brain, but affect many regions systemically. 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 ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hippocampus
The hippocampus (via Latin from Greek , ' seahorse') is a major component of the brain of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located in the allocortex, with neural projections into the neocortex in humans, as well as primates. The hippocampus, as the medial pallium, is a structure found in all vertebrates. In humans, it contains two main interlocking parts: the hippocampus proper (also called ''Ammon's horn''), and the dentate gyrus. In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; short-term memory loss and disorientation are included among the early symptoms. Damage to the hippocampus can also result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amygdala
The amygdala (; plural: amygdalae or amygdalas; also '; Latin from Greek, , ', 'almond', 'tonsil') is one of two almond-shaped clusters of nuclei located deep and medially within the temporal lobes of the brain's cerebrum in complex vertebrates, including humans. Shown to perform a primary role in the processing of memory, decision making, and emotional responses (including fear, anxiety, and aggression), the amygdalae are considered part of the limbic system. The term "amygdala" was first introduced by Karl Friedrich Burdach in 1822. Structure The regions described as amygdala nuclei encompass several structures of the cerebrum with distinct connectional and functional characteristics in humans and other animals. Among these nuclei are the basolateral complex, the cortical nucleus, the medial nucleus, the central nucleus, and the intercalated cell clusters. The basolateral complex can be further subdivided into the lateral, the basal, and the accessory ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marxism
Marxism is a left-wing to far-left method of socioeconomic analysis that uses a materialist interpretation of historical development, better known as historical materialism, to understand class relations and social conflict and a dialectical perspective to view social transformation. It originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels. As Marxism has developed over time into various branches and schools of thought, no single, definitive Marxist theory exists. In addition to the schools of thought which emphasize or modify elements of classical Marxism, various Marxian concepts have been incorporated and adapted into a diverse array of social theories leading to widely varying conclusions. Alongside Marx's critique of political economy, the defining characteristics of Marxism have often been described using the terms dialectical materialism and historical materialism, though these terms were coined after Marx's death and ...

Time Flies When You're Having Fun
Time is the continued sequence of existence and event (philosophy), events that occurs in an apparently irreversible process, irreversible succession from the past, through the present, 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 quantification (science), quantify derivative, rates of change of physical quantity, quantities in scientific realism, material reality or in the consciousness, conscious qualia, experience. Time is often referred to as a fourth dimension, along with Three-dimensional space, three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circular definition, circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate som ...

Entertainment
Entertainment is a form of activity that holds the attention and interest of an audience or gives pleasure and delight. It can be an idea or a task, but 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 and were supported in 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 a private entertainment from a now enormous array of pre-recorded pro ...

Zippy The Pinhead
Zippy the Pinhead is a fictional character who is the protagonist of ''Zippy'', an American comic strip created by Bill Griffith. Zippy's most famous quotation, "Are we having fun yet?", appears in ''Bartlett's Familiar Quotations'' and became a catchphrase. He almost always wears a yellow muumuu/ clown suit with large red polka dots, and puffy, white clown shoes. (Other forms of attire may be seen when appropriate to the context, e.g. a toga.) Although in name and appearance, Zippy is a microcephalic, he is distinctive not so much for his skull shape, or for any identifiable form of brain damage, but for his enthusiasm for philosophical non sequiturs ("All life is a blur of Republicans and meat!"), verbal free association, and the pursuit of popular culture ephemera. His wholehearted devotion to random artifacts satirizes the excesses of consumerism. The character of Zippy the Pinhead initially appeared in underground publications during the 1970s. The ''Zippy'' comic is di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expression (linguistics)
In syntax and grammar, a phrase is a group of words or singular word acting as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent. Common and technical use There is a difference between the common use of the term ''phrase'' and its technical use in linguistics. In common usage, a phrase is usually a group of words with some special idiomatic meaning or other significance, such as " all rights reserved", " economical with the truth", "kick the bucket", and the like. It may be a euphemism, a saying or proverb, a fixed expression, a figure of speech, etc.. In linguistics, these are known as phrasemes. In theories of syntax, a phrase is any group of words, or sometimes a single word, which plays a particular role wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Making Fun Of
Mockery or mocking is the act of insulting or making light of a person or other thing, sometimes merely by taunting, but often by making a caricature, purporting to engage in imitation in a way that highlights unflattering characteristics. Mockery can be done in a lighthearted and gentle way, but can also be cruel and hateful, such that it "conjures images of corrosion, deliberate degradation, even subversion; thus, 'to laugh at in contempt, to make sport of' (OED)". Mockery appears to be unique to humans, and serves a number of psychological functions, such as reducing the perceived imbalance of power between authority figures and common people. Examples of mockery can be found in literature and the arts. Etymology and function The root word ''mock'' traces to the Old French ''mocquer'' (later ''moquer''), meaning to scoff at, laugh at, deride, or fool, although the origin of ''mocquer'' is itself unknown. Labeling a person or thing as a mockery may also be used to imply that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Happiness
Happiness, in the context of mental or emotional states, is positive or pleasant emotions ranging from contentment to intense joy. Other forms include life satisfaction, well-being, subjective well-being, flourishing and eudaimonia. Since the 1960s, happiness research has been conducted in a wide variety of scientific disciplines, including gerontology, social psychology and positive psychology, clinical and medical research and happiness economics. Definitions "Happiness" is subject to debate on usage and meaning, and on possible differences in understanding by culture. The word is mostly used in relation to two factors: * the current experience of the feeling of an emotion (affect) such as pleasure or joy, or of a more general sense of 'emotional condition as a whole'. For instance Daniel Kahneman has defined happiness as "''what I experience here and now''". This usage is prevalent in dictionary definitions of happiness. * appraisal of life satisfaction, s ...
