Changes in perception FOLLOWING YOGA PRACTICE

Changes in perception FOLLOWING YOGA PRACTICE The perception is the feeling of complexity due to factors such as memories and emotions. Yoga practice influences perception in three ways: (1) increase the sensitivity of perception, (2) a selective closure "? adverse stimuli, and (3), changing distorted perception, which occurs in schizophrenia. The practice of yoga and improve visual perception, hearing, increasing the sensitivity to different features of stimuli (eg, intensity, frequency). In addition, electrophysiological studies using evoked potentials have shown that the practice of yoga during the transmission of sensory information is facilitated. These studies suggest several applications of Yoga, in activities ranging from aviation to art. Interestingly, other studies suggest that the practice of yoga can also help to reduce? adverse exteal stimuli, which may be due to connections of cortical sensory feedback pathway. It is also possible that through changes in cognitive factors yoga influences perception, so that even if the stimulus is perceived? is not worrying. This concept has been studied using yoga to help people suffering from chronic pain to ignore voluntarily. Finally, preliminary studies have shown that the practice of yoga in May modify distorted perception in conditions such as schizophrenia. Therefore, there is enough research to support the idea that the practice of yoga influences perception in different ways, with various applications. Perception is the process of interpretation, organization and development of a commodity? feeling (1). Feeling of sensory receptors and pathways, whereas perception is a cognitive process. The perception of sensation depends on factors such as what has been leaed, memories and emotions. It 'also important to remember that, while usually refers to the perception of sensory stimuli, this definition can be extended to the perception of situations. The records of the center of latency auditory evoked potentials (AEP-MLRS) has shown that the practice of pranayama Ujjayi amending AEP-MLRS components in two ways. A specific component (Na wave) has reduced amplitude and increased latency during pranayama practice (2). These results suggest that this practice facilitates the processing of auditory information at mesencephalic and diencephalic levels. A similar result was also observed during the practice of meditation on the syllable Om (3), where subjects who had more than ten years of meditation experience, showed an increase in the Na wave amplitude and a decrease in the sound? latency while mentally repeating (OM). N. this effect was observed when the same subjects, "a mental test?, during a session control for comparison purposes. These electrophysiological data are corroborated by neuropsychological studies. Previous studies have shown meditation significant changes in perception, attention and cognition (4). Brown and Engler in 1980 (5), reported that meditators were found to be more sensitive to subtle aspects of color and shading of the Rorschach inkblot test, than they were before the meditation. Two studies on critical Flicker Fusion Frequency have shown that the sensitivity of perception is not limited to subtle aspects of stimulation, such as the detection of flicker stimulation at high frequency was found to improve following the formation of yoga (6.7). A study on the degree of geometric visual illusions on the basis of M? Ller-lyer lines demonstrated that the combination of focusing and defocusing yoga exercises reduced visual illusion optical focusing only more (8). These studies were conducted on adult subjects with different durations of yoga training. It 'was reported in a recent study on Critical Flicker Fusion Frequency and optical illusion on children who practiced yoga for a period of 10 days there was also a significant improvement following the practice of yoga (9). To obtain an optical illusion with minimal error and the perception of the exact depth of the space component of visual perception is necessary (10). The decrease of the degree of optical illusion perceived over a short period is due primarily to the cognitive process, but not retinal or cortical factors as generally understood (11). Cognitive factors involve judgments of how the subject interprets the visual information based on experience, hypothesis and testing strategies. Thus, training through yoga and focus could influence Defocus cognitive process of individuals, to reduce significantly the degree of optical illusion perceived. Critical flicker fusion frequency (CFF), on the other hand, assesses the temporal component of perception of a visual stimulus (12). The increase in the CFF following yoga can be attributed to the physiological effects of yoga reducing signs of stress, such as CFF was found to be lowest during stress, such as deprivation of food and water (13). This shows that both spatial and temporal components of visual perception are modified following yoga practices. Therefore, the electronic data and visual, neuropsychological studies cited above have shown that the practice of yoga improves different aspects of visual and auditory stimuli in volunteers. An interesting difference in auditory perception (based on AEP-MLRS) were also observed in congenital blind children (14) and adults (15) than those with normal sight. The proposed changes better auditory perception which may be a compensatory mechanism of auditory sensation, in the presence of poor visibility. The effect of yoga was observed on the perception of situations. Examples of a change in the way of perceiving the situation of people was observed in both groups of subjects. A study of 69 elderly patients (over 60 years), residing in a residence for the elderly, showed that after 6 months of yoga practice there was a reduction in their feelings of depression, based on the Geriatric Depression Scale suggests a favorable change in the wy they perceived their situation (16). Another study in ten patients with breast cancer (stage 2 and 3), showed reduced anxiety and depression (Beck's Depression Scale, Spielberger d? State and Trait Anxiety Inventory), after practicing yoga for 6 months. So, probably, yoga can have positive effects on both sensory perception and how the situations or circumstances that are perceived (17). Finally, in May there will be multiple ways of perceiving the world we know. As the renowned sensory neurophysiologist, Veon B. Mountacastle said:? Each of us lives inside? .. The prison of his brain. Projected to millions of fragile sensory nerve fibers, particularly in groups adapted to sample the energy of the world around us: the heat, light, strength and chemical composition. That's all we know directly, while the rest is logical inference? (18). Yoga can allow a physician to develop advanced siddhis? or special powers, allowing May in which that person to another, can be extended? perception of the world.
