“…Key to the perception of this form of tactile motion is detecting changes in the amplitude of vibrations, and then processing these complex patterns in to extract information about the instantaneous location of vibration source. Arachnids such as spiders, approximately 700 million years apart from vertebrates in evolution, possess such mechanisms to identify preys based on complex vibration patterns [12]. In mammalian glabrous skin, two types of rapidly adapting mechanoreceptors, Meissner's and Pacinian corpuscles are sensitive to vibrations [13][14][15][16][17].…”

“…Humans actively collect information and interact with the surrounding environment through their fingers [3]. This form of motion relies on the asynchrony between the contentious streams of vibro-tactile input to two or more fingertips, analogous to detecting and localising mates, preys or predators in arthropods such as in chelicerae, by sensing substrate vibrations with their appendages [12]. The spatial extent of this form of motion spans beyond the the area of contacts and the body.…”

Motion is one of the fundamental qualities not only of vision, but also of touch. Manipulation and exploration of objects involves different forms of movement between the skin and object. A different form of tactile motion from remote sources is through substrate vibrations, and is present in arthropods such as insects and spiders, enabling them to localise approaching preys and predators. Here, we quantify the extent to humans perceive motion based on vibrations sensed at fingertips. We employed a novel stimulation paradigm in which a pair of vibrations (100 Hz) with sinusoidal envelopes (0.5 cycle/s) and various phase differences between the two vibrations were delivered to two fingertips. The phase difference generated the perception of a virtual motion across the fingertips. The findings suggest that human tactile system possesses the sensory channel for detection of motion through substrate vibrations, which is fundamentally different from active surface exploration mechanisms. We propose two potential neural computations underlying processing this form of motion; one based on phase difference detection, and the second based on temporal interval duration processing.

“…Given the position of the SGO and DO in the hemolymph channel, what functional implications and relevance could the membrane have? For the connective tissues of internal sensory organs, the material properties are not well analyzed (Strauß & Stritih-Peljhan, 2022). However, some general effects of the connection between the two organs could be suggested.…”

“…For the activation of the sensilla, the contact to the medium or the coupling to other parts of the body transferring stimuli like movements, vibration or sound is crucial, leading to specialized orientations of sensilla or attachments of the sensory organs (Bässler, 1977; Schnorbus, 1971; Strauß & Stritih‐Peljhan, 2022). Especially for the internal chordotonal organs, the structural connections to other elements of the insect body are important, for example, for proprioception or detection of substrate vibrations.…”

In insects, the detection of mechanical stimuli from body movements, airborne sound, substrate vibration, medium flow, or gravity by mechanosensory organs plays an important role. These mechanosenory organs can have complex morphologies with numerous sensilla, and the functional morphology with specific attachments of the sensory neurons to surrounding tissues and structures determines the stimulation. In stick insects, the subgenual organ complex in the tibia of all legs is an elaborate system of two chordotonal organs, which respond to substrate vibrations, and associated tibial campaniform sensilla, which respond to cuticular strain. One chordotonal organ, the distal organ, is characterized by a linear set of sensilla. This distal organ has not been studied for its physiological characteristics in detail, but the attachment or mechanical coupling is functionally important. Here we characterize two aspects of attachment or mechanical coupling of the distal organ: At the dorsal side, the organ is connected to the inner side of the dorsal cuticle by connective tissue, which is shown to also contain the axons of campaniform sensilla. At the proximal end, a fine membrane runs to the adjacent chordotonal organ, the subgenual organ. This membrane spans the tibia in transverse direction. It does not contain neuronal elements, but as a connection between the subgenual and the distal organ, it may influence the mechanosensory activity of these organs. Such a connection is not present in other insects such as locusts or cockroaches and could affect the sensory function in stick insects (e.g., in vibration detection by the subgenual organ) or even couple the two organs, resulting in similar mechanical responses.
