  author={Didhiti Mukherjee and Greta Sokoloff and Mark S. Blumberg},
In week-old rats, somatosensory input arises predominantly from external stimuli or from sensory feedback (reafference) associated with myoclonic twitches during active sleep. A previous study suggested that the brainstem motor structures that produce twitches also send motor copies (or corollary discharge, CD) to the cerebellum. We tested this possibility by recording from two precerebellar nuclei—the inferior olive (IO) and lateral reticular nucleus (LRN). In most IO and LRN neurons, twitch… Expand
Sensory coding of limb kinematics in developing primary motor cortex
It is revealed that M1 undergoes a sudden transition in its receptive field properties and population-level activity during the second postnatal week, which marks the onset of the next stage in M1 development before the emergence of its later-emerging capacity to influence motor outflow. Expand
Active Sleep Promotes Coherent Oscillatory Activity in the Cortico-Hippocampal System of Infant Rats.
By cutting the infraorbital nerve to prevent the conveyance of sensory feedback from whisker twitches, cortical-hippocampal beta2 coherence during AS was substantially reduced, demonstrating the necessity of sensory input, particularly during AS, for coordinating rhythmic activity between these two developing forebrain structures.

Developmental onset of a cerebellar-dependent forward model of movement in motor thalamus
Using rats at postnatal days (P) 12, P16, and P20, neural activity in two thalamic structures are compared: the ventral posterior (VP) and ventral lateral (VL) nuclei, both of which receive somatosensory input but only the latter of which receives cerebellar input. Expand
A developmental transition in the sensory coding of limb kinematics in primary motor cortex
The kinematic features of forelimb movements are quantified to reveal receptive-field properties of individual units within theForelimb region of M1 and reveal a transition toward a more complex and informationally rich representation of movement long before M1 develops its motor functionality.

Parallel and Serial Sensory Processing in Developing Primary Somatosensory and Motor Cortex
This study investigates the early development of S1 and M1 as a sensory processing unit in unanesthetized rats and provides new insights into the fundamental principles of sensory processing and the development of functional connectivity between these important sensorimotor structures. Expand
The Cerebellar Nuclei and Dexterous Limb Movements
Forelimb movement deficits observed when cerebellar circuits are perturbed are described, the mechanisms through which these circuits influence motor output, and key challenges in defining how the cerebellum refines limb movement are described. Expand

Evidence for corollary discharge inputs to the cerebellum is described and the hypothesized roles for this information in cerebellar motor-related computations are highlighted to inform the exciting but still untested roles of corollsary discharge in cognition, perception, and thought control relevant in psychiatric disorders.

It is now clear that sleep provides a critical context for the processing of sensory input and the expression of functional connectivity throughout the sensorimotor system. Expand
Gain control in the sensorimotor system.
The ubiquitous presence of sensory gain control across species at multiple levels of the nervous system reflects the importance of tuning the impact that feedback information has on behavioral output. Expand
Does what we dream feel present? Two varieties of presence and implications for measuring presence in VR
What’s presented in our normal waking perceptual visual experiences feels present to us, while what we “see” in pictures and imagine does not. What about dreams? Does what we “see” in a dream feelExpand


Sensorimotor Processing in the Newborn Rat Red Nucleus during Active Sleep
It is indicated that twitching, which is characterized by discrete motor output and reafferent input, provides an opportunity for sensorimotor integration and activity-dependent development of topography within the newborn RN. Expand
Gating of reafference in the external cuneate nucleus during self-generated movements in wake but not sleep
This work identifies the external cuneate nucleus (ECN), which processes sensory input from the forelimbs, as a site of movement-dependent sensory gating during wake, and demonstrates the first demonstration of a neural comparator that is differentially engaged depending on the kind of movement produced.

REM sleep twitches rouse nascent cerebellar circuits: Implications for sensorimotor development
It is proposed that twitching comprises a unique class of self‐produced movement that drives critical aspects of activity‐dependent development in the cerebellum and other sensorimotor systems. Expand
Event time representation in cerebellar mossy fibres arising from the lateral reticular nucleus
The lateral reticular nucleus (LRN) sends dense mossy fibre projections to the cerebellum, and the concerted activity of the hyperpolarisation‐activated cation conductance and the small‐conductance calcium‐activated potassium conductance is shown, which shortens the latency and sharpens the precision of post‐inhibitory spiking.

Maturation of evoked mossy fiber input to rat cerebellar Purkinje cells (II)
The results showed that Purkinje cells can receive input from the periphery via the mossy fiber system at least by the seventh postnatal day, which is relatively early in overall cerebellar development. Expand
Rapid Whisker Movements in Sleeping Newborn Rats
It is reported in 3- to 6-day-old rats that whiskers twitch rapidly and asynchronously during active sleep; furthermore, neurons in whisker thalamus exhibit bursts of activity that are tightly associated with twitches but occur infrequently during waking. Expand
Convergence of pontine and proprioceptive streams onto multimodal cerebellar granule cells
Using cell-type-specific projection mapping with synaptic resolution, this work observed the convergence of separate sensory and basilar pontine pathways onto individual granule cells and mapped this convergence across cerebellar cortex, providing evidence that the convergent basilar Pontine pathways carry corollary discharges from upper body motor cortical areas.

Twitch-related and rhythmic activation of the developing cerebellar cortex.
Results indicate that the neurophysiological activity of the developing cerebellum can be used to make inferences about changes in its microcircuitry, and support the hypothesis that sleep-related twitches are a prominent source of discrete climbing and mossy fiber activity that could contribute to the activity-dependent development of this critical sensorimotor structure.

Microcircuitry and function of the inferior olive
It is proposed that the microcircuitry of the inferior olive is capable of functioning both in motor learning and motor timing, but does not directly compare intended with achieved movements. Expand
