Useful signals from motor cortex.
Historically, the motor cortical function has been explained as a funnel to muscle activation. This invokes the idea that motor cortical neurons, or 'upper motoneurons', directly cause muscle contraction just like spinal motoneurons. Thus, the motor cortex and muscle activity are inextricably entwined like a puppet master and his marionette. Recently, this concept has been challenged by current...
متن کاملThursday : Plenary three : Neuroprosthetics and useful signals from motor cortex
We hope that the abstracts give a flavour of the exciting, diverse and interesting talks throughout the workshop. The talks were selected not only to summarise the different fields and state-of-the-art work, but also to stimulate interesting discussions. After the plenary and paper abstracts, which are in order of presentation, there are volunteered poster abstracts and stimulating articles. We...
متن کاملMovement Initiation Signals in Mouse Whisker Motor Cortex
Frontal cortex plays a central role in the control of voluntary movements, which are typically guided by sensory input. Here, we investigate the function of mouse whisker primary motor cortex (wM1), a frontal region defined by dense innervation from whisker primary somatosensory cortex (wS1). Optogenetic stimulation of wM1 evokes rhythmic whisker protraction (whisking), whereas optogenetic inac...
متن کاملDirect classification of all American English phonemes using signals from functional speech motor cortex.
OBJECTIVE Although brain-computer interfaces (BCIs) can be used in several different ways to restore communication, communicative BCI has not approached the rate or efficiency of natural human speech. Electrocorticography (ECoG) has precise spatiotemporal resolution that enables recording of brain activity distributed over a wide area of cortex, such as during speech production. In this study, ...
متن کاملSignals from the ventrolateral thalamus to the motor cortex during locomotion.
The activity of the motor cortex during locomotion is profoundly modulated in the rhythm of strides. The source of modulation is not known. In this study we examined the activity of one of the major sources of afferent input to the motor cortex, the ventrolateral thalamus (VL). Experiments were conducted in chronically implanted cats with an extracellular single-neuron recording technique. VL n...
