Dominant Patterns of Information Flow in the Propagation of the Neuromagnetic Somatosensory Steady-State Response

Frontiers in Neural Circuits, 2019
Methods of functional connectivity are applied ubiquitously in studies involving non-invasive whole-brain signals, but may be not optimal for exploring the propagation of the steady-state responses, which are strong oscillatory patterns of neurodynamics ...

Representation of Object Size in the Somatosensory System [PDF]

Journal of Neurophysiology, 2006
In this study we investigate the haptic perception of object size. We report the results from four psychophysical experiments. In the first, we ask subjects to discriminate the size of objects that vary in surface curvature and compliance while changing contact force.

Encoding of tactile stimuli by mechanoreceptors and interneurons of the medicinal leech

Frontiers in Physiology, 2016
For many animals processing of tactile information is a crucial task in behavioral contexts like exploration, foraging and stimulus avoidance. The leech, having infrequent access to food, developed an energy efficient reaction to tactile stimuli ...

The homuncular jigsaw: investigations of phantom limb and body awareness following brachial plexus block or avulsion [PDF]

, 2019
Many neuropsychological theories agree that the brain maintains a relatively persistent representation of one's own body, as indicated by vivid "phantom" experiences.

Massive cortical reorganization in sighted Braille readers

eLife, 2016
The brain is capable of large-scale reorganization in blindness or after massive injury. Such reorganization crosses the division into separate sensory cortices (visual, somatosensory...).

Higher Network Activity Induced by Tactile Compared to Electrical Stimulation of Leech Mechanoreceptors

Frontiers in Physiology, 2018
The tiny ensemble of neurons in the leech ganglion can discriminate the locations of touch stimuli on the skin as precisely as a human fingertip. The leech uses this ability to locally bend the body-wall away from the stimulus. It is assumed that a three-

Enhancing touch sensibility by sensory retraining in a sensory discrimination task via haptic rendering

Frontiers in Rehabilitation Sciences, 2022
Stroke survivors are commonly affected by somatosensory impairment, hampering their ability to interpret somatosensory information. Somatosensory information has been shown to critically support movement execution in healthy individuals and stroke ...

Sensory Electrical Stimulation Improves Foot Placement during Targeted Stepping Post-Stroke [PDF]

, 2014
Proper foot placement is vital for maintaining balance during walking, requiring the integration of multiple sensory signals with motor commands. Disruption of brain structures post-stroke likely alters the processing of sensory information by motor ...

A NaV1.8FlpO mouse enabling selective intersectional targeting of low threshold C fiber mechanoreceptors and nociceptors

Frontiers in Molecular Neuroscience
Genetic targeting of select populations of cells in the mouse nervous system is often hampered by a lack of selectivity, as candidate genes for such targeting are commonly expressed by multiple cell populations, also in the same region.

A Critical Period for the Rapid Modification of Synaptic Properties at the VPm Relay Synapse

Frontiers in Molecular Neuroscience, 2017
In addition to cortical areas, the thalamus also displays plasticity during a critical period in early life. Since most sensory information is transmitted to the cortex via the thalamus, it will be of significant interest to understand the precise time ...
