Dynamic range adaptation in primary motor cortical populations
Neural populations from various sensory regions demonstrate dynamic range adaptation in response to changes in the statistical distribution of their input stimuli. These adaptations help optimize the transmission of information about sensory inputs. Here, we show a similar effect in the firing rates of primary motor cortical cells. We trained monkeys to operate a brain-computer interface in bot...
متن کاملIII-99. Dynamic range adaptation in motor cortical neurons
Neurons from various sensory regions have been shown to demonstrate gain control or dynamic range adaptation in response to changes in the statistical distribution of their input stimuli. Although a similar phenomenon has been observed in single neurons in primary motor cortex (M1) during an isometric force task (Hepp-Raymond, et. al. Exp Brain Res 1999 128:123-133), the mechanisms behind this ...
متن کاملCortical processing during dynamic motor adaptation.
In this chapter we investigate the role of motor cortex in adapting movements to novel dynamic environments. We present results from two experiments in which monkey or human subjects learned to make two-dimensional reaching movements while holding a robotic manipulandum that applied a predictable pattern of forces (a curl field) to their hand. In the first study, we analyzed electrophysiologica...
متن کاملPrimary motor cortical discharge during force field adaptation reflects muscle-like dynamics.
We often make reaching movements having similar trajectories within very different mechanical environments, for example, with and without an added load in the hand. Under these varying conditions, our kinematic intentions must be transformed into muscle commands that move the limbs. Primary motor cortex (M1) has been implicated in the neural mechanism that mediates this adaptation to new moveme...
متن کاملTime course of dynamic range adaptation in the auditory nerve.
Auditory adaptation to sound-level statistics occurs as early as in the auditory nerve (AN), the first stage of neural auditory processing. In addition to firing rate adaptation characterized by a rate decrement dependent on previous spike activity, AN fibers show dynamic range adaptation, which is characterized by a shift of the rate-level function or dynamic range toward the most frequently o...
