San Religion
The San religion is the traditional religion and mythology of the San people. It is poorly attested due to their interactions with Christianity. Gods and mythical figures ;ǀXam The ǀXam prayed to the Sun and Moon. Many myths are ascribed to various stars. * ǀKágge̥n (sometimes corrupted to "Cagn") is Mantis, a demiurge and hero in ǀXam folklore. He is a trickster god who can shape-shift.

Khoikhoi
Khoekhoen (singular Khoekhoe) (or Khoikhoi in the former orthography; formerly also ''Hottentot (racial term), Hottentots''"Hottentot, n. and adj." ''OED Online'', Oxford University Press, March 2018, www.oed.com/view/Entry/88829. Accessed 13 May 2018. Citing G. S. Nienaber, 'The origin of the name “Hottentot” ', ''African Studies'', 22:2 (1963), 65-90, . See also . ) are the traditionally Nomad, nomadic pastoralist Indigenous peoples of Africa, indigenous population of southwestern Africa. They are often grouped with the hunter-gatherer San people, San (literally "Foragers") peoples. The designation "Khoekhoe" is actually a ''kare'' or praise address, not an ethnic endonym, but it has been used in the literature as an ethnic term for Khoe–Kwadi languages, Khoe-speaking peoples of Southern Africa, particularly pastoralist groups, such as the Griqua people, !Ora, !Gona, Nama people, Nama, Khoemana, Xiri and Damara people, ǂNūkhoe nations.

Tutelary Deity
A tutelary () (also tutelar) is a deity or a spirit who is a guardian, patron, or protector of a particular place, geographic feature, person, lineage, nation, culture, or occupation. The etymology of "tutelary" expresses the concept of safety and thus of guardianship. In late Greek and Roman religion, one type of tutelary deity, the ''genius'', functions as the personal deity or ''daimon'' of an individual from birth to death. Another form of personal tutelary spirit is the familiar spirit of European folklore. Ancient Greece Socrates spoke of hearing the voice of his personal spirit or ''daimonion'': The Greeks also thought deities guarded specific places: for instance, Athena was the patron goddess of the city of Athens. Ancient Rome Tutelary deities who guard and preserve a place or a person are fundamental to ancient Roman religion. The tutelary deity of a man was his Genius, that of a woman her Juno. In the Imperial era, the Genius of the Emperor was a focus of Imperia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a ''geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geometries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Art
In archaeology, rock art is human-made markings placed on natural surfaces, typically vertical stone surfaces. A high proportion of surviving historic and prehistoric rock art is found in caves or partly enclosed rock shelters; this type also may be called cave art or parietal art. A global phenomenon, rock art is found in many culturally diverse regions of the world. It has been produced in many contexts throughout human history. In terms of technique, the four main groups are: * cave paintings, * petroglyphs, which are carved or scratched into the rock surface, * sculpted rock reliefs, and * geoglyphs, which are formed on the ground. The oldest known rock art dates from the Upper Palaeolithic period, having been found in Europe, Australia, Asia, and Africa. Anthropologists studying these artworks believe that they likely had magico-religious significance. The archaeological sub-discipline of rock art studies first developed in the late-19th century among Francophone scholar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Migraine
Migraine (, ) is a common neurological disorder characterized by recurrent headaches. Typically, the associated headache affects one side of the head, is pulsating in nature, may be moderate to severe in intensity, and could last from a few hours to three days. Non-headache symptoms may include nausea, vomiting, and photophobia, sensitivity to light, hyperacusis, sound, or Osmophobia, smell. The pain is generally made worse by physical activity during an attack,as PDF although regular physical exercise may prevent future attacks. Up to one-third of people affected have Aura (symptom), aura: typically, it is a short period of visual disturbance that signals that the headache will soon occur. Occasionally, aura can occur with little or no headache follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperventilation
Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. This leads to hypocapnia, a reduced concentration of carbon dioxide dissolved in the blood. The body normally attempts to compensate for this homeostatically, but if this fails or is overridden, the blood pH will rise, leading to respiratory alkalosis. The symptoms of respiratory alkalosis include: dizziness, tingling in the lips, hands or feet, headache, weakness, fainting, and seizures. In extreme cases it may cause carpopedal spasms, a flapping and contraction of the hands and feet. Factors that may induce or sustain hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, and adverse ...

Sensory Deprivation
Sensory deprivation or perceptual isolation is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down. Sensory deprivation has been used in various alternative medicines and in psychological experiments (e.g. with an isolation tank). When deprived of sensation, the brain attempts to restore sensation in the form of hallucinations. Short-term sessions of sensory deprivation are described as relaxing and conducive to meditation; however, extended or forced sensory deprivation can result in extreme anxiety, hallucinations, bizarre thoughts, temporary senselessness, and depression A related phenomenon is perceptual deprivation, also called the Ganzfeld effect. In this case a constant uniform stimulus is used instead of att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entoptic Phenomenon
Entoptic phenomena () are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz's words: "Under suitable conditions light falling on the eye may render visible certain objects within the eye itself. These perceptions are called ''entoptical''." Overview Entoptic images have a physical basis in the image cast upon the retina. Hence, they are different from optical illusions, which are caused by the visual system and characterized by a visual percept that (loosely said) appears to differ from reality. Because entoptic images are caused by phenomena within the observer's own eye, they share one feature with optical illusions and hallucinations: the observer cannot share a direct and specific view of the phenomenon with others. Helmholtz commented on entoptic phenomena which could be seen easily by some observers, but could not be seen at all by others. This variance is ...

Neuropsychology
Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology often focus on how injuries or illnesses of the brain affect cognitive and behavioral functions. It is both an experimental and clinical field of psychology, thus aiming to understand how behavior and cognition are influenced by brain function and concerned with the medical diagnosis, diagnosis and therapy, treatment of behavioral and cognitive effects of neurological disorders. Whereas classical neurology focuses on the pathology of the nervous system and classical psychology is largely divorced from it, neuropsychology seeks to discover how the brain neural correlates of consciousness, correlates with the mind through the study of neurological patients. It thus shares concepts and concerns with neuropsychiatry and with behavioral neurology in general. The term ''neuropsychology'' h ...

Altered State Of Consciousness
An altered state of consciousness (ASC), also called altered state of mind or mind alteration, is any condition which is significantly different from a normal waking state. By 1892, the expression was in use in relation to hypnosis, though there is an ongoing debate as to whether hypnosis is to be identified as an ASC according to its modern definition. The next retrievable instance, by Dr Max Mailhouse from his 1904 presentation to conference, however, is unequivocally identified as such, as it was in relation to epilepsy, and is still used today. In academia, the expression was used as early as 1966 by Arnold M. Ludwig and brought into common usage from 1969 by Charles Tart. It describes induced changes in one's mental state, almost always temporary. A synonymous phrase is "altered state of awareness". Definitions There is no general definition of an altered state of consciousness, as any definitional attempt would first have to rely on a definition of a normal state of consci ...

Hallucination
A hallucination is a perception in the absence of an external stimulus that has the qualities of a real perception. Hallucinations are vivid, substantial, and are perceived to be located in external objective space. Hallucination is a combination of 2 conscious states of brain wakefulness and REM sleep. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from "delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Many hallucinations happen also during sleep paralyses. Hallucinations can occur in any sensory modality—visual, auditory, olfa ...

Kudu
The kudus are two species of antelope of the genus ''Tragelaphus'': * Lesser kudu, ''Tragelaphus imberbis'', of eastern Africa * Greater kudu, ''Tragelaphus strepsiceros'', of eastern and southern Africa The two species look similar, though greaters are larger than lessers. A large adult male greater kudu stands over tall at the shoulder, and a large male lesser kudu stands about tall. Males of both species have long horns, which point upward and slightly back, curling in a corkscrew shape. Etymology The name of the animal was imported into English in the 18th century from isiXhosa ''iqhude'', via Afrikaans ''koedoe''. Kudu, or koodoo, is the Khoikhoi and seTswana name for this antelope. ''Tragos'' (Greek) denotes a he-goat and ''elaphos'' (Greek) a deer. ''Strepho'' (Greek) means "I twist", and ''strephis'' is "twisting". ''Keras'' (Greek) means "horn". Habitat Lesser kudus occupy savanna near '' Acacia'' and ''Commiphora'' shrubs. They rely on thickets for prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
