Surround inhibition and its benefits in somatosensory system Introduction Somatosensory system is a complex sensory system that is made up of different types of sensory receptors. These sensory receptors include thermo-receptors (specialised heat receptors), mechanoreceptors (specialised cells that senses pressure and distortion), chemo- receptors (specialised receptors cells that converts chemical signals in action potential), and photo- rectors (specialised cells that converts light signals in
• Touch: Our sense of touch is mainly governed by a huge network of free-nerve endings and touch receptors located near or at the surface of the skin. These receptors combined with the free-nerve endings in the skin are known as the somatosensory system. They are activated by a stimulus, which in turn makes the neural membrane more permeable to sodium ions, thus allowing an action potential to occur (given that the charge exceeds the threshold). The impulse may or may not travel to the brain depending
When you become a manager, there is a lot that is expected of you. You are expected to attend meetings, motivate and inspire, train, make decisions and so much more. With all of these expectations, when you actually have time to spend with your employees? That is the question that many managers have. Unfortunately, I do not have the answer, but I can share with you how touching base with your employees will save you time in the long run. Touching base with your employees to review projects and tasks
Yalom (2002) states that it is acceptable to touch your patients when it is needed during the therapy session. Personally, I think that touching a patient should at no time be acceptable unless a medical emergency is occurring or if it would be harmful to therapy to not touch them. Just a friendly touch could turn into something more for the patient, and those who have a mental illness could think of a variety of different meanings for that gesture. Since I have been learning about counseling, I
The Blind Man – And the Blind Shall "see" The story "The Blind Man" by D.H. Lawrence can be read at many levels. On the surface, the story is about the struggles of Maurice Pervin as he learns to cope with the loss of his sight. On a much deeper level, it can be seen that Maurice is closed in by his blindness and it is through another man's weakness that he begins to “see” again. To understand the meaning of "The Blind Man", one must first try to understand Maurice Pervin. He has spent most of
language as an expression of just how much we use our skin. But our skin may serve more purposes than those of protection and information. Through several experiments it has been demonstrated that the sense of touch is highly associated with the immune system, the development of social skills, and even the survival of the species. Montagu uses a number of case studies in which he relates skin to death rates and success in healing wounds. On one particular study done on laboratory rats where humans had
Proprioception essentially means being able to tell where one is in space. This may seem like an easy thing, especially since it is usually not something a person thinks about; however, after an injury, proprioception becomes rather difficult. In order to completely recover from the injury and safely return to play or normal daily activities, the person must work on regaining proprioception in their injured limb as well as the whole body. The authors of the study compared the proprioception of 20
that he is deprived of an important aspect for feeling love and comfort: the sense of touch. Research by Darlene Francis and Michael Meaney has shown that rats that were groomed by their mother in infancy were more calm and had a stronger immune system when they grew up (Keltner). Humans have pressure receptors called Pacinian corpuscles under their skin (Trudeau). When the pressure receptors are stimulated, it sends signals to the vagus nerve, which is responsible for lowering blood pressure
of movement, the force exerted by the muscle, and the speed and intensity with which a muscle is being stretched. It plays an important role, with the tactile and vestibular system, in developing knowledge of ones own body and its movements in order to motor plan actions (Fisher et al., 1991:84). It provides the motor system with a clear map of the external environment and of the body (Matthews, 1988; as cited in Fisher et al., 1991:84) so that, during movement, the brain can plan the next movement
due to the fact that ones are more aware the loss of visual and auditory senses as they are more salient and the deterioration of tactile senses are less noticeable. The sense of touch is considered to be an informative, active as well as perceptual system in any species. However, it is essential to point that the aspect and practice of tactile recognition plays a frequent role in an individual’s daily life. Therefore, it can be stated that tactile recognition is important and central to a human being
Through all of our every-day life, we suffer the effects of empathy in some way, shape, or form. As humans, we are anatomically built to empathize with others, but about 1.6% of us are designed to be overly empathetic, so much that they reach the extent of physically feeling what is felt by the observed person. This rare occurrence is the result of an ability known as Mirror-Touch Synesthesia. Mirror-Touch Synesthesia is a condition in which cross-activation occurs between normally separate senses
Imagery in My Papa’s Waltz Donald Hall describes the use of imagery in poetry as a device that "makes us more sensitive to [literature], as if we acquired eyes that could see through things"(p 530). Imagery creates vivid details that deal with one's sense of sight, sound, touch, smell, or taste. These details can be seen in Theodore Roethke's "My Papa's Waltz" because the senses of touch, sight, sound, and smell appeal to the reader in order to better explain the feelings of each character in
Chosen Frame of reference/ Models(s): Neurodevelopmental theory (NDT) informs clinical reasoning through the concepts of motor control, brain plasticity, motor learning and an understanding of functional human movement (Meadows & Williams, 2013). By identifying atypical movement patterns the therapist is able to select interventions, which will facilitate Sue in developing greater symmetry in her body and correct movement patterns. (Barthel, 2009; Feaver & Ezekiel, 2011). This influences the practice
DRAFTING Proprioception provides an awareness of the body and body positioning without 'continuous reference to consciousness' (Lephart et.al, 1997, p. 131). There are two types of proprioception, being conscious and unconscious. Conscious proprioception concerns joint position sense and kinetic sense (Khasnis & Gokula, 2003). Joint position sense processes joint movement and joint position sensations (Sharp et.al, 1994). These joint sensations provide the awareness of the position of the body and
Haptic: Of or relating to the sense of touch. Greek: haptikos, from haptesthai, to grasp, to touch. Seeing is believing, but touching is the truth. Haptics in Philosophy This essay is an exploration of the notion of the haptic in architecture. It will explore it in architectural design and in experience of architectural space. I will discuss perception as a precursor to haptics. In philosophical terms perception is how we understand our environment via our senses through identification and interpretation
Introduction Phenomenology can be deemed to be both an unambiguous academic research field and a theoretical design current within contemporary architecture and is usually founded on one’s experience of the materials used in construction inclusive of their sensory characteristics. In this regard, architecture is the impetus towards transformation and inspiration of an individual’s daily existence. Unlike other forms of art, architecture employs the immediacy of an individual’s sensory perception
Skepticism In Meditation 1, Descartes is confronted by the idea that throughout his life he has been taught numerous false truths. As his metaphysical knowledge is based on the things which he has been taught, they too are proven false and he is left without any indubitable ideas or beliefs. After Descartes puts all he knows under doubt, he begins to attempt to regain his knowledge of the world by thinking exclusively of absolute truths. On this mission, he encounters three arguments for accepting
1 INTRODUCTION: Haptics is a recent enhancement to virtual environments allowing users to “touch” and feel the simulated objects with which they interact. Haptics is the science of touch. The word derives from the Greek haptikos meaning “being able to come into contact with”. The study of haptics emerged from advances in virtual reality. Virtual reality is a form of human-computer interaction (as opposed to keyboard, mouse and monitor) providing a virtual environment that one can explore through
Authoritative Discourse in A Portrait of an Artist as a Young Man In James Joyce's A Portrait of An Artist As A Young Man, the main character, Stephen Dedalus, struggles between his natural instincts, or what Bakhtin calls the "internally persuasive discourse" that "[is not] backed up by [an] authority at all", and his learned response, reinforced by the "authoritative discourse" of religion. To Stephen's "internally persuasive discourse", his natural sex drive is not 'wrong'. It is only after
A Blind Man Shapes a Learning Theory The study of the behavior of blind people can provide insight and clarification regarding the learning process of humans. If a man blind from birth has learned about shapes purely by touch, when he is cured of his blindness he will not be able to recognize these shapes only by sight. The act of learning has several different aspects. One is recollection, in which a person discovers information that they had already knew, and his brain can be triggered to
