A system for tracking whisker kinematics and whisker shape in three dimensions.
PLoS Computational Biology, 2020 Quantification of behaviour is essential for biology. Since the whisker system is a popular model, it is important to have methods for measuring whisker movements from behaving animals. Here, we developed a high-speed imaging system that measures whisker

Cortical Control of Whisker Movement
Annual Review of Neuroscience, 2010 Facial muscles drive whisker movements, which are important for active tactile sensory perception in mice and rats. These whisker muscles are innervated by cholinergic motor neurons located in the lateral facial nucleus. The whisker motor neurons receive synaptic inputs from premotor neurons, which are located within the brain stem, the midbrain, and ...

Coding of whisker motion across the mouse face
eLife, 2019 Haptic perception synthesizes touch with proprioception, the sense of body position. Humans and mice alike experience rich active touch of the face.

Higher-Order Thalamic Encoding of Somatosensory Patterns and Bilateral Events
Frontiers in Neural Circuits, 2021 The function of the higher-order sensory thalamus remains unclear. Here, the posterior medial (POm) nucleus of the thalamus was examined by in vivo extracellular recordings in anesthetized rats across a variety of contralateral, ipsilateral, and ...

Whisker Sensing by Force and Moment Measurements at the Whisker Base
Soft Robotics, 2023 We address the theoretical question which forces and moments measured at the base of a whisker (tactile sensor) allow for the prediction of the location in space of the point at which a whisker makes contact with an object. We deal with the general case of three-dimensional deformations as well as with the special case of planar configurations.

Whisker Alignment in Microparts Using Laser Stereolithography with Applied Electric Field
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013 The purpose of this research is to produce microparts reinforced with unidirectional whiskers using laser stereolithography. Electrically conductive whiskers are added to a liquid photopolymer and an electric field is applied to the liquid photopolymer ...

Frontiers in Integrative Neuroscience, 2015 Rodents use active whisker movements to explore their environment. The ‘slip hypothesis’ of whisker-related tactile perception entails that short-lived kinematic events (abrupt whisker movements, called ‘slips’, due to bioelastic whisker properties that ...

Nanomaterials, 2021 A series of nanopillar compression tests were performed on tungsten as a function of temperature using in situ transmission electron microscopy with localized laser heating. Surface oxidation was observed to form on the pillars and grow in thickness with

eLife, 2016 We discovered that optical stimulation of the mystacial pad in Emx1-Cre;Ai27D transgenic mice induces whisker movements due to activation of ChR2 expressed in muscles controlling retraction and protraction.

Whisker kinematics in the cerebellum
The Journal of Physiology, 2023 AbstractThe whisker system is widely used as a model system for understanding sensorimotor integration. Purkinje cells in the crus regions of the cerebellum have been reported to linearly encode whisker midpoint, but it is unknown whether the paramedian and simplex lobules as well as their target neurons in the cerebellar nuclei also encode whisker ...
