Sensory cortical dynamics.
Sensory cortical networks are commonly regarded as stable, changing only in the face of prolonged alteration of sensory input. There is increasing evidence, however, that the functional connectivity of cortical networks changes significantly, but reversibly, in response to conditions of sensory stimulation similar to those encountered in everyday life. In this review, we provide examples of sen...
متن کاملActivated cortical states: experiments, analyses and models.
In awake animals, the cerebral cortex displays an "activated" state, with distinct characteristics compared to other states like slow-wave sleep or anesthesia. These characteristics include a sustained depolarized membrane potential (V(m)) and irregular firing activity. In the present paper, we evaluate our understanding of cortical activated states from a computational neuroscience point of vi...
متن کاملLarge-scale imaging of cortical dynamics during sensory perception and behavior.
Sensory-driven behaviors engage a cascade of cortical regions to process sensory input and generate motor output. To investigate the temporal dynamics of neural activity at this global scale, we have improved and integrated tools to perform functional imaging across large areas of cortex using a transgenic mouse expressing the genetically encoded calcium sensor GCaMP6s, together with a head-fix...
متن کاملHuman Postural Responses to Sensory Stimulations: Measurements and Model
In the paper we examined the influence of vestibular and leg proprioceptive inputs on the human upright posture. Vestibular input was changed by applying current 1 mA between places near to left and right ear. Proprioceptive input was modified by vibrating the calf muscle. Furthermore, the vestibular stimulus was combined with the muscle vibration using five different temporal relationships bet...
متن کاملEliciting naturalistic cortical responses with a sensory prosthesis via optimized microstimulation.
OBJECTIVE Lost sensations, such as touch, could one day be restored by electrical stimulation along the sensory neural pathways. Such stimulation, when informed by electronic sensors, could provide naturalistic cutaneous and proprioceptive feedback to the user. Perceptually, microstimulation of somatosensory brain regions produces localized, modality-specific sensations, and several spatiotempo...
