Medical definition of klinokinesis: movement that is induced by stimulation and that involves essentially random alteration of direction Klinokinesis synonyms, Klinokinesis pronunciation, Klinokinesis translation, English dictionary definition of Klinokinesis. n. pl. ki·ne·ses Movement or activity of an organism in response to a stimulus such as light of the whole animal (klinokinesis), the speed of frequency depending on the intensity of stimulation. Examples of orthokinesis are seen in lampreys, which are more active in high intensities of light, and in cockroaches, which are more active in low intensities; flatworms and many kinds of fly larvae, amon The original definition of the term klinokinesis was based on an account by Ullyott (1936) of the behaviour of the flatworm, Dendrocoelum lacteum, an account recently shown to be unsound
(1) A nonspecific term for any movement of an individual or group, especially toward a stimulus. (2) Motion sickness, see there. Except as a root (e.g., cytokinesis, diakinesis, etc.), kinesis is little used in the working medical parlance. Segen's Medical Dictionary. © 2012 Farlex, Inc Woodlouse activity decreases as humidity increases. Kinesis, like a taxis or tropism, is a movement or activity of a cell or an organism in response to a stimulus (such as gas exposure, light intensity or ambient temperature). Unlike taxis, the response to the stimulus provided is non-directional
C. elegans shows chemotaxis using klinokinesis where the worm senses the concentration based on a single concentration sensor to compute the concentration gradient to perform foraging through gradient ascent/descent towards the target concentration followed by contour tracking. The biomimetic implementation requires complex neurons with multiple ion channel dynamics as well as interneurons for. klinokinesis. Definition from Wiktionary, the free dictionary. Jump to navigation Jump to search. English . English Wikipedia has an article on: klinokinesis. Wikipedia . Etymology . From klino-+ -kinesis. Noun . klinokinesis (uncountable As nouns the difference between klinokinesis and orthokinesis is that klinokinesis is a form of kinesis in which the frequency or rate of turning is proportional to stimulus intensity while orthokinesis is a form of kinesis in which the speed of movement of the individual is dependent upon the intensity of the stimulus
Porcellio scaber (otherwise known as the common rough woodlouse or simply rough woodlouse), is a species of woodlouse native to Europe but with a cosmopolitan distribution.They are often found in large numbers in most regions, with many species (shrews, centipedes, toads, spiders and even some birds) preying on them klinokinesis had synergistic effects and both elements of chemokinesis may have a substantial influence on PMN velocity. The relationship between speed and changes in the direction of locomotion has been analyzed and the putative role of klinokinesis in chemotactic responses is discussed Klinokinesis Bioinformatics Tool Laverne is a handy bioinformatics tool to help facilitate scientific exploration of related genes, diseases and pathways based on co-citations.

For more information on how to use Laverne, please read the How to Guide Klinokinesis was a substantial though not the major element of the chemokinetic response to fMLP under the conditions used. No other metazoan cells have been shown to possess such a complete pattern of responses, including orthokinesis, klinokinesis, and chemotaxis, which regulate locomotion
The original definition of the term klinokinesis was based on an account by Ullyott (1936) of the behaviour of the flatworm, Dendrocoelum lacteum, an account recently shown to be unsound.Recently, the behaviour of Escherichia coli and of Salmonella typhimurium in chemical gradients has been found to conform to the definition, so the term can continue in use Kinesis is described as non-directional response by organisms to a stimulus. Organism will not move towards or away from the location of the stimulus, instead it will show random movements to get into a comfortable place. There are two categories of kinases: Orthokinesis and Klinokinesis Kinesis is a change in the speed of movement (orthokinesis) or a change in the rate of turning (klinokinesis) which is directly proportional to the intensity of a stimulus. Input from only a single sensory receptor is necessary. A kinesis is non-directed orientation, that is, the animal exhibits a random walk..
. The general term for physical movement, including that induced by stimulation, for example, light. McGraw-Hill Dictionary of Scientific & Technical Terms,... Explanation of Klinokinesis Klinokinesis is a behavioral mechanism in which an organism moves toward or away from a stimulus source by altering its frequency of change of direction without biasing its turns with respect to the stimulus field. Previous studies of a variety of organisms have demonstrated that rates of adaptation (or other information processing features) for increases and decreases in stimulus intensity.
Klinokinesis. It is another type of Kinesis where the rate of turning or frequency is directly proportional to stimulus intensity. For this particular type, we can take the example of flatworm. This particular organism likes staying in the dark and when it sees that there is an intensity of light, it tries to turn away from it rapidly and. klinokinesis the organism turns in a straight line in a favourable environment, but as soon as the environment becomes less favourable it begins making turns, until, after a time, the organism adapts or habituates and begins moving in a straight line again (this is a form of memory that allows the organism t In biology, there exist two types of motions when responding to a stimulus. These two types are called taxis and kinesis. Taxis has a specific and directed motion while kinesis has a random and undirected motion. These two are usually found in the behavior of animals and insects around us Synonyms for Klinokinesis in Free Thesaurus. Antonyms for Klinokinesis. 2 words related to kinesis: response, reaction. What are synonyms for Klinokinesis 25. The main difference between taxis and kinesis is that taxis is the directed movement of living organisms in response to a particular stimulus whereas kinesis is the random movement of living organisms.Furthermore, aerotaxis, magnetotaxis, phototaxis, and chemotaxis are the example movements of taxis while orthokinesis and Klinokinesis are the two types of kinesis
Noun. 1. kinesis - a movement that is a response to a stimulus but is not oriented with respect to the source of stimulation. response, reaction - a bodily process occurring due to the effect of some antecedent stimulus or agent; a bad reaction to the medicine; his responses have slowed with age Kinesis is the undirected movement in response to a stimulus, which can include orthokinesis (related to speed) or klinokinesis (related to turning). Taxis is the directed movement towards or away from a stimulus, which can be in response to light (phototaxis), chemical signals ( chemotaxis ), or gravity (geotaxis) Taxis have several types like phototaxis, thigmotaxis, geotaxis, chemotaxis, aerotaxis, etc.. On the other hand, kinesis is of two types, those are; orthokinesis and klinokinesis. In taxis, movement occurs towards or away but in kinesis, there is no particular direction of movement combining stretched exponential reorientation clocks with klinokinesis that fits the time length and the travelled distance distributions of the observed trajectories. 1. Introduction Over the last years, interdisciplinary interest has grown in understanding the drivers of random (non-informed) search efficiency [1,2]. This is in par
C. elegans employ two behavioral maneuvers, reversal (klinokinesis) and curve (klinotaxis) to avoid acidic pH. Unlike the chemotaxis in C. elegans, reversal and curve avoidances were triggered by absolute pH rather than temporal derivative of stimulus concentration in this behavior. The pH threshold Other articles where Orthokinesis is discussed: stereotyped response: Reflex-like activities: from rest to movement (orthokinesis) or of frequency or amount of turning of the whole animal (klinokinesis), the speed of frequency depending on the intensity of stimulation. Examples of orthokinesis are seen in lampreys, which are more active in high intensities of light, and in cockroaches.

What is Geotaxis example? The definition of geotaxis is the reaction of a free moving organism to gravity. An example of geotaxis is a flying insect being able to fly up or down In this work, we aim to devise an end-to-end spiking implementation for contour tracking in 3D media inspired by chemotaxis, where the worm reaches the region which has the given set concentration. For a planer medium, efficient contour tracking algorithms have already been devised, but a new degree of freedom has quite a few challenges. Here we devise an algorithm based on klinokinesis. Klinokinesis is a behavioral mechanism in which an organism moves toward or away from a stimulus source by altering its frequency of change of direction without biasing its turns with respect to the stimulus field. Computer simulation was used to study the efficiency of, and the effect of sensory adaptation on, this behavioral strategy
was believed to be solely klinokinesis (1, 7). However, d4-530 is repelled from sodium acetate by orthiokinesis, and, to my knowledge, this is the first report of orthokinesis in Paramecium chemokinesis. The response of paramecia to chemi-cals was measured by a T-maze assay, designedtopresentatest andcontrol so-lution to apopulationofanimals(5. With klinokinesis alone, model animals showed initial attraction to the odorant followed by avoidance, similar to, but not identical to real worms (Fig. 2b-d, klinokinesis alone) It is also important to mention the works on klinokinesis initiated in the late 1980s by Benhamou & Bovet [29-31], where they studied central-place foraging and home range emergence through the idea that animals adjust their sinuosity (defined as a measure of the 'amount of turning') as a function of their direction of motion Klinokinesis; Stimulus intensity determines the rate of turning. E.g. Flatworms turn more quickly in light, so when they leave darkened areas they turn more often, increasing the likelihood to crawl back into the dark. Orientation in Animals . Part 1: Taxis and Kinesis. Orientation Mechanisms.
The main difference between taxis and kinesis is that taxis is the directed movement of living organisms in response to a particular stimulus whereas kinesis is the random movement of living organisms.Furthermore, aerotaxis, magnetotaxis, phototaxis, and chemotaxis are the example movements of taxis while orthokinesis and klinokinesis are the two types of kinesis enacademic.com EN. RU; DE; FR; ES; Remember this sit A class of orientation behavior characterized by undirected movements in which the frequency of turning (klinokinesis) or speed of movement (orthokinesis) is related to the intensity of the stimulation. A change in the rate of movement in response to an environmental condition, with the direction of the movement random and unrelated to the. In conclusion, we have presented a scale-invariant, adaptive chemotaxis algorithm using spiking neurons that successfully combines klinotaxis, klinokinesis and orthokinesis. This allows us to perform robust, resource constrained and energy efficient contour tracking while achieving state-of-the-art performance
MR. YAPP'S communication on this subject 1 is of considerable interest because it suggests that temperature may be a more suitable stimulus than pH for making a quantitative investigation of klino-kinesis in Paramecium. A quantitative study is required to discover how completely the klino-kinesis scheme describes behaviour in gradients . These behaviors are often plastic depending on previous experiences. Caenorhabditis elegans , which has highly developed chemosensory system with a limited number of sensory neurons, is an ideal model for analyzing the role
taxis [tak´sis] (Gr.) 1. an orientation movement of a motile organism in response to a stimulus; it may be either toward (positive) or away from (negative) the source of the stimulus. See also tropism. 2. exertion of force in manual replacement of a displaced organ or part. Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied. Stimuli that produces a change in direction (such as turning) is known as klinokinesis. Movement influenced by gravity is known as geokinesis, and changes of movement caused by water currents is known as rheokinesis. Kinetic responses also can be in reaction to chemical and temperature stimuli (chemokinesis and thermokinesis, respectively). The.

Source for information on klino-kinesis: A Dictionary of Ecology dictionary We study central-place foraging patterns of Aphaenogaster senilis ants at a population level by video framing individual ant trajectories in a circular arena with a nest connected to its centre. The ants naturally leave and enter the nest and forage generating non-trivial movement patterns around the nest. Our data analysis indicated that the trajectories observed can be classified into two.
C. elegans shows chemotaxis and thermotaxis toward favorable chemicals and temperature, respectively [3, 4], both of which are achieved through three behavioral strategies: (1) biased random walk (i.e., klinokinesis), a repeated, abrupt, random reorientation until the worm is headed in a favorable direction [5-7], (2) non-random steering (i.e. Biology Investigation: Woodlice. 1925 Words8 Pages. * Biology Investigation 3.1 Porcellio Scaber (Slater, Woodlouse) Task 1 The crustacean Porcellio Scaber, or more commonly known as the woodlouse, is a species usually found in leaf litter or in fallen trees and bark.

movement while klinokinesis deals with the change in the rate of turning (Kendeigh, 1961). Taxis Taxis might be positive or negative and it is always directional. If it is directed towards a stimulus, it is positive taxis and its intensity increases with the movement towards the source. Fo Greek: orthos - straight) or path sinuosity (klinokinesis). Sinuosity is a purely spatial measure to describe the amount of turning associated with a path, regardless of details of movement. Alternatively, if turns are typically sharp and infrequent, researchers use turning frequency to describe the turning events associated with a path
Klinokinesis. OrthokinesisOrthos(Greek) = straight. In orthokinesis, the intensity of the stimulus governs the speed of movement. It is the frequency of change from rest to movement Behavioral Biology: Proximate and Ultimate Causes of Behavior Behavior is the change in activity of an organism in response to a stimulus. Behavioral biology is the study of the biological and evolutionary bases for such changes. The idea that behaviors evolved as a result of the pressures of natural selection is not new

(external link Klinokinesis refers to a strategy in which an animal changes the frequency of random turning in response to the (change of) intensity of stimuli. Bacterial chemotaxis is a well known example of klinokinesis, in which decrease in chemical concentration induces a tumbling which leads to a change of the direction of migration Also, typically klinokinesis involves random reorientation of the heading - is this also accounted for by the modulation of the oscillatory pattern? The models presented in this paper do not include (do not address) klinokinesis (stopping). This was a deliberate decision as our goal is to understand the extent to which the oscillatory.
