    The Proprioceptive Map of the Arm Is Systematic and Stable, but Idiosyncratic

    Visual and somatosensory signals participate together in providing an estimate of the hand's spatial location. While the ability of subjects to identify the spatial location of their hand based on visual and proprioceptive signals has previously been characterized, relatively few studies have examined in detail the spatial structure of the proprioceptive map of the arm. Here, we reconstructed and analyzed the spatial structure of the estimation errors that resulted when subjects reported the location of their unseen hand across a 2D horizontal workspace. Hand position estimation was mapped under four conditions: with and without tactile feedback, and with the right and left hands. In the task, we moved each subject's hand to one of 100 targets in the workspace while their eyes were closed. Then, we either a) applied tactile stimulation to the fingertip by allowing the index finger to touch the target or b) as a control, hovered the fingertip 2 cm above the target. After returning the hand to a neutral position, subjects opened their eyes to verbally report where their fingertip had been. We measured and analyzed both the direction and magnitude of the resulting estimation errors. Tactile feedback reduced the magnitude of these estimation errors, but did not change their overall structure. In addition, the spatial structure of these errors was idiosyncratic: each subject had a unique pattern of errors that was stable between hands and over time. Finally, we found that at the population level the magnitude of the estimation errors had a characteristic distribution over the workspace: errors were smallest closer to the body. The stability of estimation errors across conditions and time suggests the brain constructs a proprioceptive map that is reliable, even if it is not necessarily accurate. The idiosyncrasy across subjects emphasizes that each individual constructs a map that is unique to their own experiences

    Arts for the blues – a new creative psychological therapy for depression

    Routinely prescribed psychological therapies for depression are not always effective. Arts therapies, particularly Dance Movement Psychotherapy, may offer additional therapeutic mechanisms for depression. Therefore, client-reported helpful factors from various therapy types, along with client preferences, are key in devising new therapeutic interventions. We present a framework for a new pluralistic “meta-approach” of therapy for depression, based on an interdisciplinary thematic synthesis (Thomas, J., & Harden, A. (2008). Methods for the thematic synthesis of qualitative research in systematic reviews. BMC Medical Research Methodology, 8(1), 45) of active ingredients from both talking therapies and creative approaches. Lastly, we offer an example group therapy workshop based on this approach, to be piloted with clients and practitioners within an NHS mental health service. Further research is required to evaluate this pilot and to devise a full treatment for trialling within the service

    This study aimed to determine the in vitro antibacterial activities of essential oil from cinnamon bark (Cinnamomum burmannii) on Methicillin-resistant Staphylococcus aureus (MRSA) isolated from raw milk. Essential oil from cinnamon bark obtained from the steam distillation method and essential oil was made in a series dilution with a concentration of 1%, 2%, 4%, and 8%. The antibacterial activities were tested using the disk diffusion method. Results showed from five isolates of MRSA, one isolate was sensitive of essential oil with a concentration 2% and all of the isolate was sensitive with a concentration 4% and 8%. The antibacterial activity showed by inhibition zones on MRSA. The results suggest that the activity of the essential oils of cinnamon bark has an antibacterial effect on MRSA and it is developed as phytopharmaca
