Coding of object location in the vibrissal thalamocortical system.
In whisking rodents, object location is encoded at the receptor level by a combination of motor and sensory related signals. Recoding of the encoded signals can result in various forms of internal representations. Here, we examined the coding schemes occurring at the first forebrain level that receives inputs necessary for generating such internal representations--the thalamocortical network. S...

متن کاملTemporal and spatial coding in the rat vibrissal system.
In light of the spatio-temporal nature of the world around us, it is not surprising that sensory encoding is based on spatial and temporal cues that encode static and dynamic events. Spatial encoding of the world is accomplished by arrays of receptors, which are spatially organized across the sensory organs. Each receptor is most sensitive to a specific and limited range within the sensation sp...
متن کاملOrthogonal coding of object location.
It has been argued whether internal representations are encoded using a universal ('the neural code') or multiple codes. Here, we review a series of experiments that demonstrate that tactile encoding of object location via whisking employs an orthogonal, triple-code scheme. Rats, and other rodents, actively move the whiskers back and forth to localize and identify objects. Neural recordings fro...
متن کاملDecoupling kinematics and mechanics reveals coding properties of trigeminal ganglion neurons in the rat vibrissal system
Tactile information available to the rat vibrissal system begins as external forces that cause whisker deformations, which in turn excite mechanoreceptors in the follicle. Despite the fundamental mechanical origin of tactile information, primary sensory neurons in the trigeminal ganglion (Vg) have often been described as encoding the kinematics (geometry) of object contact. Here we aimed to det...
