Cortical control of a whisking central pattern generator.
Whether the motor cortex regulates voluntary movements by generating the motor pattern directly or by acting through subcortical central pattern generators (CPGs) remains a central question in motor control. Using the rat whisker system, an important model system of mammalian motor control, we develop an anesthetized preparation to investigate the interaction between the motor cortex and a whis...
متن کاملThe Central Pattern Generator for Rhythmic Whisking
Whisking and sniffing are predominant aspects of exploratory behavior in rodents. We review evidence that these motor rhythms are coordinated by the respiratory patterning circuitry in the ventral medulla. A region in the intermediate reticular zone, dorsomedial to the preBötzinger inspiratory complex, provides rhythmic input to the facial motoneurons that drive protraction of the vibrissae. Ne...
متن کاملWhisker deafferentation and rodent whisking patterns: behavioral evidence for a central pattern generator.
Even in the absence of explicit stimulation, rats emit patterns of rhythmic whisking movements. Because of their stereotyped nature and their persistence after sensory denervation and cortical ablation, whisking movements have been assumed to reflect the output of a central pattern generator (CPG). However, identification of a movement pattern as the product of a CPG requires evidence that its ...
متن کاملCentral Pattern Generator Control of a Tensegrity Based Swimmer
There has been an increased interest in the development of biologically inspired vehicles and robotics, as they have the potential of outperforming the current state of the art in metrics of efficiency, economy, maneuverability, and stealth. In marine applications, unmanned underwater vehicles currently rely on the steady state propellor or screw, which can be inefficient, noisy, application sp...
متن کاملDistributed Central Pattern Generator Control for a Serpentine Robot
We have built a biologically and neurally inspired autonomous mobile robotic worm. The main aim of the project is to demonstrate elegant motion on a robot with a large number of degrees of freedom (DOFs) under the control of a simple distributed neural system as found in many animals’ spinal cord. Our robot consists of individually controlled segments that exhibit Central-Pattern-Generator (CPG...
