“…Pain sensation is palpably crucial for survival, and even the gentlest of touches is vital. For instance, lack of tactile sensory stimuli at the beginning of life has adverse effects on growth and neuronal development (1). Mammalian skin is invaded by a multitude of mechanoreceptor neurons that vary in their sensitivity to mechanical loads, their response dynamics, and their structure (2,3).…”

Interactions with the physical world are deeply rooted in our sense of touch and depend on ensembles of somatosensory neurons that invade and innervate the skin. Somatosensory neurons convert the mechanical energy delivered in each touch into excitatory membrane currents carried by mechanoelectrical transduction (MeT) channels. Pacinian corpuscles in mammals and touch receptor neurons (TRNs) in Caenorhabditis elegans nematodes are embedded in distinctive specialized accessory structures, have low thresholds for activation, and adapt rapidly to the application and removal of mechanical loads. Recently, many of the protein partners that form native MeT channels in these and other somatosensory neurons have been identified. However, the biophysical mechanism of symmetric responses to the onset and offset of mechanical stimulation has eluded understanding for decades. Moreover, it is not known whether applied force or the resulting indentation activate MeT channels. Here, we introduce a system for simultaneously recording membrane current, applied force, and the resulting indentation in living C. elegans (Feedback-controlled Application of mechanical Loads Combined with in vivo Neurophysiology, FALCON) and use it, together with modeling, to study these questions. We show that current amplitude increases with indentation, not force, and that fast stimuli evoke larger currents than slower stimuli producing the same or smaller indentation. A model linking body indentation to MeT channel activation through an embedded viscoelastic element reproduces the experimental findings, predicts that the TRNs function as a band-pass mechanical filter, and provides a general mechanism for symmetrical and rapidly adapting MeT channel activation relevant to somatosensory neurons across phyla and submodalities.

“…Touch is also important for social exchange, including pair bonding and child rearing (Tessier et al 1998;Feldman et al 2010). Infants deprived of touch stimuli display developmental and cognitive deficits (reviewed in Kaffman and Meaney 2007;Ardiel and Rankin 2010). For example, premature babies show delayed development and growth but this can be improved by 45 minutes of daily touch stimulation.…”

Our skin is the furthest outpost of the nervous system and a primary sensor for harmful and innocuous external stimuli. As a multifunctional sensory organ, the skin manifests a diverse and highly specialized array of mechanosensitive neurons with complex terminals, or end organs, which are able to discriminate different sensory stimuli and encode this information for appropriate central processing. Historically, the basis for this diversity of sensory specializations has been poorly understood. In addition, the relationship between cutaneous mechanosensory afferents and resident skin cells, including keratinocytes, Merkel cells, and Schwann cells, during the development and function of tactile receptors has been poorly defined. In this article, we will discuss conserved tactile end organs in the epidermis and hair follicles, with a focus on recent advances in our understanding that have emerged from studies of mouse hairy skin.

“…It is a very interesting finding that physical contact with children is a subjective well-being increasing strategy. Physical contact has been found to facilitate development and growth for both people and animal species (Ardiel and Rankin, 2010). From a psychological point of view, physical contact has a vital prescription to form attachment patterns.…”

Subjective well-being is a sign of positive mental health of children. The aim of the present study is to develop subjective well-being increasing strategies scale for children whose mothers' uses are varied 1 to 5. In this study, there were 195 mothers whose mean ages were 31, 49 and standard deviation were 4,71. Satisfaction with life, positive and negative affect scales were used. Moreover, item analysis, exploratory factor analysis, reliability and validity analysis were used. According to results, the scale has 66,03 % explained variance and four dimensions which were named as acting physical contact, playing game, satisfaction of desires and take out. The reliability and validity of the scale have enough values. The scale is valid and reliable. In future, some researches might carry out with this scale in order to increase children's' physical and mental health.
