The Neurophysiology of Tactile Perception: A Tribute to Steven Hsiao
Steven Hsiao was the Scientific Director of the Johns Hopkins University Zanvyl Krieger Mind/Brain Institute until his untimely death on June 16, 2014. The focus of Steve’s career was to understand the neural basis of tactile perception. This Collection from Journal of Neurophysiology is related to somatosensory neurophysiology, including the encoding of tactile signals by sensory receptors, the processing of tactile signals by the central nervous system, and neural mechanisms for perceiving tactile signals.

Listen as Jeff Yau (Baylor College of Medicine) describes his experience working with Steve Hsiao at Johns Hopkins University, summarizes his contribution to our collection of articles on the neurophysiology of tactile perception, and discusses the value of this collection for those involved in somatosensory research.
Listen as Sliman Bensmaia (University of Chicago) recollects working with Steve Hsiao, summarizes his contribution to our collection of articles on the neurophysiology of tactile perception, and discusses the breadth of the somatosensory research represented in the collection.
Cover: Multiregional Brain-on-a-Chip in vitro model. Neurons (green) from different brain regions (here prefrontal cortex, left, and amygdala, right) are restricted to distinct areas, but are connecting controllably to the other brain region through axons which are guided by microcontact printed lines. This is a zoom in image from the entire brain-on-a-chip model, which consists of three brain regions. This multiregional brain-on-a-chip is electrically active and reacts to drug applications in a brain region dependent way. Astrocytes are labelled in red. The smallest distance between the different brain areas is 1 mm. From Dauth S, Maoz BM, Sheehy SP, Hemphill MA, Murty T, Macedonia MK, Greer AM, Budnik B, Parker KK.
