In psychology, sensation is the first stage in the biochemical and neurologic events that begins with the impinging of a stimulus upon the receptor cells of a sensory organ, which then leads to perception, the mental state that is reflected in statements like "I see a uniformly blue wall." A sensation that might lead to that statement could include the excitation of cone cells in the retina, spatially varying in the proportion of "blue" and "green" cone excitation due to portions of the wall receiving different proportions of y ...

Definition and meaning of Sensation

Sensation - [Psychology]

Sensation is knowledge of the world based on chemical and electrical processes within the nervous system, particularly in the brain. A stimulus is anything which causes chemical, electrical and mechanical activity in sense receptors. The initial electrical activity caused by sensory stimulation is a sensation.

The doctrine of Paticca-samuppada is the cornerstone of Buddhism. It says nothing happens without a cause, and every cause has an effect. This law applies to every entity living or dead, big or small, from individual to communities, societies to nations.

Paticca-samuppada is also called the law of cause and effect. Paticca means 'dependent upon’, samuppada means 'arising’. This doctrine is applied to the wheel of life, which consists of 12 interdependent causes and effects.

A sensation of falling occurs when the labyrinth or vestibular apparatus, a system of fluid-filled passages in the inner ear, detects motion. The same system also detects rotary motion. A similar sensation of falling can be induced when the eyes detect rapid apparent motion with respect to the environment. This system enables us to keep our balance by signalling when a physical correction is necessary. When a human [Alyson Innes] is in free fall in an orbiting spacecraft, or in an aircraft in a steep dive, the sensation ...

The Allure of Tantra

Perhaps nothing is more exotic, dramatic and sensational in IndiaÕs Yoga traditions than is the practice of Tantra. No other approach to Yoga has gained such a fascination for the modern mind and its seeking of the bizarre, the entertaining and the enigmatic.

Tantra appears to offer both spiritual and worldly success to a superlative degree. It covers not only internal yogic experiences of chakras, lokas and deities, but also has many important healing practices for body and mind. Most notably, it offers special means of heightening sexual pleasure, making money, gaining recognition and defeating oneÕs enemies - with Tantric methods available for achieving all human desires. There is in Tantra something for everyone, especially those who may be put off by ascetic or renunciate approaches to the spiritual life such as seem to dominate most of the rest of the Yoga tradition.

Octopuses have keen eyesight. Although their slit-shaped pupils might be expected to afflict them with astigmatism, it appears that this is not a problem in the light levels in which an octopus typically hunts. Surprisingly, they do not appear to have color vision, although they can distinguish the polarization of light. Attached to the brain are two special organs, called statocysts, that allow the octopus to sense the orientation of its body relative to horizontal. An autonomic response keeps the octopus's eyes oriented so that ...

Idealism is the doctrine that whatever exists, or at least everything that can be known to exist, is mental. (Opposed to materialism: "All there is, is matter")

On this view, tables may be real, and independent of our sensations of tables, as long as they are something like ideas - and provided ideas can cause sensations.

Our sensations of tables are to some extent subjective, the sensations cannot exist except in perception. Therefore, nothing can be immediately known except what is in the mind.

When I meditate I experience physical pain in my body. What should I do?

Sensations (itching/aches/pains/etc.) can arise in the body when meditating for several reasons. Sometimes the cause is just an uncomfortable posture--make sure that your posture is comfortable under normal circumstances.

Other times the cause is that sensations in the body are more noticeable in meditation.

Psychophysics is the branch of cognitive psychology dealing with the relationship between physical stimuli and their perception. While the majority of research has been done on vision, the discipline covers all the senses; papers have even been published on extrasensory perception, although more prosaic alternatives like hearing, taste, touch (including skin and enteric perception), smell, and sense of time are the more prevalent. The most straightforward use of psychophysics is the study of perceptual correlates for var ...

14 in two suborders, see text. The octopus is a cephalopod of the order Octopoda that inhabits many diverse regions of the ocean, especially coral reefs. The term may also refer to only those creatures in the genus Octopus. In the larger sense, there are 289 different octopus species, which is over one-third the total number of cephalopod species. Octopuses are characterized by their eight arms, usually with sucker cups on them. These arms are a type of muscular hydrostat. Unlike most other cephalopods, the ...

Human taste sensory organs, called taste buds or gustatory calyculi, are concentrated on the upper surface of the tongue. They appear to be receptive to relatively few chemical species as tastes. This contrasts markedly with the sense of olfaction(smell), where very large numbers of chemicals can be differentiated. Basic taste - History. Five tastes are known to be sensed by taste buds: bitter, salty, sour, sweet, and umami. Until recently, most Western sources listed only the first four; in recent y ...

In the physical sciences, weight is the downward force exerted on matter as a result of gravity, especially the earth's gravity. An object's weight is equal to its mass multiplied by the magnitude of the gravitational field.

The word "weight" is commonly used synonymously with "mass", though the two concepts are technically quite distinct. Weight - Weight and mass. In scientific usage weight ...
