Studies investigating human motor learning and movement perception have shown that similar sensorimotor brain regions are engaged when we observe or perform action sequences. However, the way these networks enable translation of complex observed actions into motor commands-such as in the context of dance-remains poorly understood. Emerging evidence suggests that the ability to encode specific visuospatial and kinematic movement properties encountered via different routes of sensorimotor experience may be an integral component of action learning throughout development...

The characterization of brain subnetwork segregation and integration has previously focused on changes that are detectable at the level of entire sessions or epochs of imaging data. In this study, we applied time-varying functional connectivity analysis together with temporal network theory to calculate point-by-point estimates in subnetwork segregation and integration during an epoch-based (2-back, 0-back, baseline) working memory fMRI experiment as well as during resting-state. This approach allowed us to follow task-related changes in subnetwork segregation and integration at a high temporal resolution...

Vasogenic cerebral edema formation after blood brain barrier (BBB) damage aggravates the devastating consequences of intracerebral hemorrhage (ICH). The present study aims to probe into a therapeutic method on BBB preservation after ICH with a glycogen synthase kinase-3β (GSK-3β) inhibitor, lithium. Intrastriatal infusion of semicoagulated autologous whole blood or sham surgery was performed on male Sprague-Dawley (SD) rats (n = 208).Experimental animals received administration of 4,6-disubstitutedpyrrolo-pyrimidine (TWS119), lithium alone or in combination with a phosphatidylinositol 3-kinase inhibitor, wortmannin, after ICH...

Ethanol intoxication (EI) is a frequent comorbidity of TBI, but the impact of EI on TBI pathogenic cascades and prognosis is unclear: although clinical evidence suggests that EI may have neuroprotective effects, experimental support is, to date, inconclusive. We aimed at elucidating the impact of EI on TBI-associated neurological deficits, signaling pathways and pathogenic cascades, in order to identify new modifiers of TBI pathophysiology. We have shown that ethanol administration (5g/Kg) before trauma enhances behavioral recovery in a weight-drop TBI model; neuronal survival in the injured somatosensory cortex was enhanced by EI...

Recent years have seen a surge of interest in the incorporation of artificial limbs. This research promises to provide individuals with sensorimotor disorders such as amputations with prostheses which feel like their own body part. While neuroscience made a leap towards uncovering the basic neurocognitive mechanisms of bodily self-consciousness, the development of incorporated prosthetic limbs still faces substantial challenges in basic neuroscience and in clinical reality. Here we critically examine recent findings on prosthesis incorporation to aid patient rehabilitation in the context of advances in cognitive and applied neuroscience as well as technology...

The ability to transfer sensorimotor skill components to new actions and the capacity to use skill components from whole actions are characteristic of the adaptability of the human sensorimotor system. However, behavioral evidence suggests complex limitations for transfer after combined or modular learning of motor adaptations. Also, to date, only behavioral analysis of the consequences of the modular learning has been reported, with little understanding of the sensorimotor mechanisms of control and the interaction between cortical areas...

Development of normal feeding is a highly complex sensorimotor process that depends upon the integration of neurological maturation, internal motivation and experiential learning (1-3). Disruption of the child's feeding process can lead to feeding problems during infancy and early childhood. One of the most widely used and validated scales for measuring whether a child's feeding problem has clinical significance is the Behavioral Pediatric Feeding Assessment Scale (BPFAS) (4). The objective of this study was to translate the BPFAS into Greek and culturally adapt the scale to evaluate the psychometric properties among the Greek parents of normally developing children...

Reference frame Transformations (RFTs) are crucial components of sensorimotor transformations in the brain. Stochasticity in RFTs has been suggested to add noise to the transformed signal due to variability in transformation parameter estimates (e.g. angle) as well as the stochastic nature of computations in spiking networks of neurons. Here, we varied the RFT angle together with the associated variability and evaluated the behavioral impact in a reaching task that required variability-dependent visual-proprioceptive multi-sensory integration...

Group musical improvisation is thought to be akin to conversation, and therapeutically has been shown to be effective at improving communicativeness, sociability, creative expression, and overall psychological health. To understand these therapeutic effects, clarifying the nature of brain activity during improvisational cognition is important. Some insight regarding brain activity during improvisational music cognition has been gained via functional magnetic resonance imaging (fMRI) and electroencephalography (EEG)...

BACKGROUND: strong embodiment theories claimed that action language representation is grounded in the sensorimotor system, which would be crucially to semantic understanding. However, there is a large disagreement in literature about the neural mechanisms involved in abstract (symbolic) language comprehension. OBJECTIVE: in the present study, we investigated the role of motor context in the semantic processing of abstract language. We hypothesized that motor cortex excitability during abstract word semantic processing could be modulated by previous presentation of a stimuli which associated a congruent motor content (i...

Type 2 diabetes mellitus (DM) is a major and growing health problem. Brain-related effects of type 2 DM have been studied in several ways over the past few decades. Results have shown effects on brain structure, incidence of dementia, and impairment of various cognitive functions. The present study examined a sample of clinically-referred patients with type 2 DM and compared them with a sample of control patients who were matched on a pairwise basis on age, education, and gender. Each patient was tested using a comprehensive, integrated neuropsychological test battery...

Introduction: The aging process leads to functional decline of sensorial organs, muscle mass and strength, as well as the sensorimotor integration, culminating in age-associated postural control impairments. The purpose of this study was to compare the balance, the sensorial integration process and the lower limb strength among three old aged groups. Methods: Eighty-one community-dwelling healthy old people (58% women), assigned into three age groups [60-69 years (n=30), 70-79 years (n=40), and ≥80 years (n=11)], participated in this study...

Recent studies have revealed that the ventral premotor cortex (PMv) of nonhuman primates plays a pivotal role in various behaviors that require the transformation of sensory cues to appropriate actions. Examples include decision-making based on various sensory cues, preparation for upcoming motor behavior, adaptive sensorimotor transformation, and the generation of motor commands using rapid sensory feedback. Although the PMv has frequently been regarded as a single entity, it can be divided into at least five functionally distinct regions: F4, a dorsal convexity region immediately rostral to the primary motor cortex (M1); F5p, a cortical region immediately rostral to F4, lying within the arcuate sulcus; F5c, a ventral convexity region rostral to F4; and F5a, located in the caudal bank of the arcuate sulcus inferior limb lateral to F5p...

BACKGROUND: The functional architecture of resting-state networks (RSNs) is defined by their connectivity and metastability. Disrupted RSN connectivity has been amply demonstrated in schizophrenia while the role of metastability remains poorly defined. Here, we undertake a comprehensive characterisation of RSN organization in schizophrenia and test its contribution to the clinical profile of this disorder. METHODS: We extracted RSNs representing the default mode (DMN), central executive (CEN), salience (SAL), language (LAN), sensorimotor (SMN), auditory (AN) and visual (VN) networks from resting-state functional magnetic resonance imaging data obtained from patients with schizophrenia (n = 85) and healthy individuals (n = 48)...

REVIEW
Steven Knafo, Claire Wyart
The investigation of mechanosensory feedback to locomotion has been hindered by the challenge of recording neurons in motion. Genetic accessibility and optical transparency of zebrafish larvae provide means to revisit this question. Glutamatergic Rohon-Beard (RB) and GABAergic CSF-contacting neurons (CSF-cNs) are spinal mechanosensory neurons. Recent studies combining bioluminescence, silencing and optogenetic activation show that mechanosensory neurons enhance speed and stabilize posture during locomotion...

Recent research has shown that chiropractic spinal manipulation can alter central sensorimotor integration and motor cortical drive to human voluntary muscles of the upper and lower limb. The aim of this paper was to explore whether spinal manipulation could also influence maximal bite force. Twenty-eight people were divided into two groups of 14, one that received chiropractic care and one that received sham chiropractic care. All subjects were naive to chiropractic. Maximum bite force was assessed pre- and post-intervention and at 1-week follow up...

Multisensory convergence and sensorimotor integration are important aspects for the mediation of higher vestibular cognitive functions at the cortical level. In contrast to the integration of vestibulo-visual or vestibulo-tactile perception, much less is known about the neural mechanism that mediates the integration of vestibular-otolith (linear acceleration/translation/gravity detection) and auditory processing. Vestibular-otolith and auditory afferents can be simultaneously activated using loud sound pressure stimulation, which is routinely used for testing cervical and ocular vestibular evoked myogenic potentials (VEMPs) in clinical neurotological testing...

Parallel corticostriatonigral circuits have been proposed that separately process motor, cognitive, and emotional-motivational information. Functional integration requires that interactions exist between neurons participating in these circuits. This makes it imperative to study the complex anatomical substrate underlying corticostriatonigral circuits. It has previously been proposed that dopaminergic neurons in the ventral mesencephalon may play a role in this circuit interaction. Therefore, we studied in rats convergence of basal ganglia circuits by depositing an anterograde neuroanatomical tracer into the ventral striatum together with a retrograde fluorescent tracer ipsilaterally in the dorsolateral striatum...

The present study used event-related potential (ERP) recordings to investigate the neural mechanisms of sensorimotor adaptation in response to altered auditory feedback (AAF) during vocal production. 12 healthy speakers were tested under a vocal motor adaptation paradigm in which the fundamental frequency (F0) of their voice auditory feedback was pitch-shifted downward by one semi-tone (- 100 cents) during vowel vocalizations. Behavioral results revealed that subjects adapted to AAF by producing opposing (upward) responses to pitch-shift stimuli, and this adaptive behavior persisted after feedback alteration was removed (washout)...
