Distortion of mental body representations

MR Longo - Trends in Cognitive Sciences, 2022 - cell.com
Our body is central to our sense of self, and distorted body representations are found in
several serious medical conditions. This paper reviews evidence that distortions of body …

A conceptual model of tactile processing across body features of size, shape, side, and spatial location

L Tamè, E Azañón, MR Longo - Frontiers in psychology, 2019 - frontiersin.org
The processing of touch depends of multiple factors, such as the properties of the skin and
