2. 6. Tactile touch in intensive care : Nurses' preparation, patients' experiences and the effect on stress parameters

   Author : Maria Henricson; Bengt Fridlund; Kerstin Segesten; Anna-Lena Berglund; Sylvia Määttä; Karlstads universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tactile touch; intensive care; stress; oxytocin; complementary method; nursing; preparation; randomised controlled trial; comfort; lifeworld research; narratives; Nursing; Omvårdnad; Nursing Science; Omvårdnad;

   Abstract : Aim: The overall aim of this thesis was to acquire knowledge about whether tactile touch as a complementary method can (i) promote comfort and (ii) reduce stress reactions during care in an intensive care unit (ICU) Method: In Paper I, five nurses with a touch therapist training were interviewed about their experiences of preparation before giving tactile touch in an ICU. To analyse the meaning of preparation as a phenomenon, Giorgi’s descriptive phenomenological approach was used. READ MORE

4. 7. Sense of Touch in Robots

   Author : Magnus Johnsson; Kognitionsvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; touch perception; neural network; robot hand; brain model; cognitive model; robot model; tensor network; associative self-organizing map; SOM; proprioception;

   Abstract : This thesis discusses a number of robot touch perception systems. All these systems are self-organizing and model different aspects of human touch perception. The thesis starts out with introductions to the anatomy and the physiology of the human hand. READ MORE

5. 8. A pathway for pleasant touch: linking peripheral receptors to central processing and hedonic experience

   Author : Line Sofie Löken; Göteborgs universitet; []
   Keywords : pleasant; touch; microneurography; human; CT afferent; unmyelinated;

   Abstract : This thesis investigates the mechanisms underpinning pleasant touch, describes a pathway from peripheral nerve endings in the skin to the insular cortex, and relates these findings to the subjective hedonic experience of touch. In Paper I, the relationship between primary afferent encoding and perception of pleasantness was investigated by combining microneurography recordings from human mechanoreceptors with psychophysical measurements during soft brush stroking at 6 different velocities between 0.

6. 9. Machine learning for identification of brain activity patterns with applications in gentle touch processing

   Author : Malin Björnsdotter Åberg; Göteborgs universitet; []
   Keywords : Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

   Abstract : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.

7. 10. Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis

   Author : Elin Eriksson Hagberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aβ afferent; C-tactile; touch; EEG; MEG; SEEG;

   Abstract : The present work summarizes investigations of the temporal correlates of brain activity elicited by gentle, moving touch on the hairy skin in healthy participants and in epilepsy patients. Light touch to the hairy skin activates two distinct afferent classes: fast conducting, Aβ afferents and slowly conducting C-tactile (CT) afferents. READ MORE
