Visual illusion of tool use recalibrates tactile perception.
TLDR
Visual tool-use signals play a critical role in driving tool embodiment, and recalibration was not found following illusory passive tool holding, and could not be accounted for by sensory conflict or general interhemispheric plasticity.About:

Synaesthesia in phantom Limbs induced with mirrors
TL;DR: An inexpensive new device is introduced - a ‘virtual reality box’ - to resurrect the phantom visually to study the effects of visual input on phantom sensations, suggesting that there is a considerable amount of latent plasticity even in the adult human brain.

A Conceptual Model of Tactile Processing across Body Features of Size, Shape, Side, and Spatial Location.
TL;DR: A wide range of neuropsychological, neuroimaging, and neurophysiological data is reviewed and a revised model of tactile integration on the basis of the one proposed previously by Longo et al. is suggested.

Mapping the internal geometry of tactile space.
Matthew R. Longo,Olga Golubova +1 more
TL;DR: The results show that distortions in perceived tactile distance can be characterized by geometrically simple and coherent deformations of tactile space, and suggest that the internal geometry of tactilespace is shaped by the geometry of receptive fields in somatosensory cortex.

Tactile distance illusions reflect a coherent stretch of tactile space
F. Fiori,Matthew R. Longo +1 more
TL;DR: A model of tactile distance illusions in terms of a geometrically simple stretch of tactile space is developed and tested, and it is demonstrated that the pattern of perceived tactile distances across orientations is consistent with the model’s predictions.

The impact of multisensory integration and perceptual load in virtual reality settings on performance, workload and presence.
Matteo Marucci,Gianluca Di Flumeri,Gianluca Borghini,Nicolina Sciaraffa,Michele Scandola,Enea Francesco Pavone,Fabio Babiloni,Viviana Betti,Pietro Aricò +8 more
TL;DR: In this article, the authors used a realistic virtual reality environment while concomitantly acquiring EEG and Galvanic Skin Response (GSR) to investigate how multisensory signals impact target detection in two conditions, high and low perceptual load.

Rubber hands ‘feel’ touch that eyes see
TL;DR: An illusion in which tactile sensations are referred to an alien limb is reported, which reveals a three-way interaction between vision, touch and proprioception, and may supply evidence concerning the basis of bodily self-identification.

The psychometric function: I. Fitting, sampling, and goodness of fit
Felix A. Wichmann,N. Jeremy Hill +1 more
TL;DR: An integrated approach to fitting psychometric functions, assessing the goodness of fit, and providing confidence intervals for the function’s parameters and other estimates derived from them, for the purposes of hypothesis testing is described.

CORTICAL PLASTICITY: From Synapses to Maps
TL;DR: The goal of the current paper is to review the fields of both synaptic and cortical map plasticity with an emphasis on the work that attempts to unite both fields, to highlight the gaps in the understanding of synaptic and cellular mechanisms underlying cortical representational plasticity.
Journal ArticleDOI
Computational principles of movement neuroscience
TL;DR: This goal is to demonstrate how specific models emerging from the computational approach provide a theoretical framework for movement neuroscience.

Coding of modified body schema during tool use by macaque postcentral neurones
TL;DR: Macaque monkeys are trained to retrieve distant objects using a rake, and neuronal activity was recorded in the caudal postcentral gyrus where the somatosensory and visual signals converge, and a large number of bimodal neurones appeared to code the schema of the hand.
