Abstract Vestibular‐evoked balance responses are facilitated when faced with threats to stability. However, the extent which these sensorimotor adaptations covary changes in emotional and autonomic state remains unclear. This study repeatedly exposed individuals same postural threat while vestibular‐motor were probed using stochastic vestibular stimulation (SVS; 2–25 Hz). allowed be manipulated within environment determine if vestibular‐evoked coupled emotional/autonomic induced by or a...
Abstract Height-induced postural threat influences standing balance control. However, it is unknown if minimizing individuals’ emotional response to moderates this relationship. This study repeatedly exposed individuals height-induced determine reducing the Sixty-eight young adults completed a series of trials at LOW (0.8 m above ground, away from edge) and HIGH (3.2 conditions. Emotional state was assessed using self-report electrodermal measures. Standing through analysis centre pressure...
Neurons coordinate their activity to produce an astonishing variety of motor behaviors. Our present understanding control has grown rapidly thanks new methods for recording and analyzing populations many individual neurons over time. In contrast, current the nervous system's actual output - activation muscle fibers by typically cannot detect electrical events produced during natural behaviors scale poorly across species groups.

During unperturbed bipedal standing, postural control is governed primarily by subcortical and spinal networks. However, it unclear if cortical networks begin to play a greater role when stability threatened. This study investigated how initial repeated exposure height-related threat modulates potentials time-locked discrete centre of pressure (COP) events during standing. Twenty-seven young adults completed series 90-s standing trials at LOW (0.8 m above the ground, away from edge) HIGH...
Key points Threats to standing balance (postural threat) are known facilitate soleus tendon‐tap reflexes, yet the mechanisms driving reflex changes unknown. Scaling of ramp‐and‐hold dorsiflexion stretch reflexes velocity and amplitude were examined as indirect measures muscle spindle dynamic static function with height‐induced postural threat. Overall, larger Furthermore, slope (gain) stretch‐velocity vs . short‐latency relationship was increased These findings interpreted evidence for...
Humans exhibit changes in postural control when confronted with threats to stability. This study used a prolonged threat exposure protocol manipulate emotional state within threatening context determine if any threat-induced standing behaviours are employed independent of state. Retention balance adaptations was also explored. Thirty-seven adults completed series 90-s trials at two surface heights (LOW: 0.8 m above ground, away from edge; HIGH: 3.2 edge) on visits 2-4 weeks apart....

Previous research has investigated synergies involved in locomotion and balance reactions; however, there is limited insight into the emergence of skilled control with practice challenging tasks. We explored motor learning tandem single leg stance on an unstable surface-a slackline. Balance was tested 10 naïve healthy adults at four time points: baseline, after one slackline session, 1 week practice, following final session. recorded kinematics upper lower arms bilaterally, trunk, thigh foot...

Spinal interneurons play a critical role in motor output. A given interneuron may receive convergent input from several different sensory modalities and descending centers relay this information to just as many targets. Therefore, there is need quantify populations of spinal simultaneously. Here, we the functional connectivity neurons through concurrent recording lumbar hindlimb units vivo cat model during activation either ipsilateral sural nerve or contralateral tibial nerve. Two...
