The 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 کاملCortical 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 کاملWhisking
Eyes may be 'the window to the soul' in humans, but whiskers provide a better path to the inner lives of rodents. The brain has remarkable abilities to focus its limited resources on information that matters, while ignoring a cacophony of distractions. While inspecting a visual scene, primates foveate to multiple salient locations, for example mouths and eyes in images of people, and ignore the...
متن کاملWhat generates whisking? Focus on: "The whisking rhythm generator: a novel mammalian network for the generation of movement".
A central goal of neuroscience is to explain how neural networks generate organized and repetitive motor patterns, such as active whisking used by rodents to navigate the environment. Whisking consists of fast rhythmic ellipsoid vibrissae movements through the air and over objects at between 4 and 15 Hz, which are characterized by vibrissa protractions (Berg and Kleinfeld 2003; Carvell and Simo...
متن کاملOne whisker whisking: unit recording during conditioned whisking in rats.
Understanding of the functional neurobiology of the rodent whisker system would be advanced by neurobehavioral studies in awake, behaving animals that combine unit recording from structures at various levels of the system with quantitative characterization of the kinematics and temporal organization of whisking. Such studies require the solution of a number of methodological problems. These inc...
