“…A more realistic model of the corticomuscular pathway is needed to provide a mechanistic understanding of the entire system. Recent studies have discussed “closing the loop” between the computations of the brain and biomechanical representations of body ( James et al., 2018 ; Mascaro et al., 2020 ; Pérez Fernández et al., 2021 ). James et al.…”

“…(2017) used six neurons corresponding to each muscle in the upper limb arm model to directly control the spinal motoneurons. Pérez Fernández et al. (2021) used a more complex neural model of three layers representing the sensory input, interneurons and α -motoneurons, respectively, with 48 neurons in each layer.…”

“…Despite advances towards integrated modelling of the neuromuscular system, the contribution of the central nervous system (CNS), or any supraspinal input, is rarely considered. Recently, attempts have been made towards modelling more complex representations of the corticomuscular pathway ( Teka et al., 2017 ; James et al., 2018 ; Pérez Fernández et al., 2021 ). These models are important milestones towards a holistic approach of motor pathway modelling but are limited in scope since they either consider very specialised pathways, such as the control of eye movement ( James et al., 2018 ; Pérez Fernández et al., 2021 ), or use simplified model components ( Teka et al., 2017 ).…”

Thus, these modelling frameworks are not suited to investigate the complex interplays within the corticomuscular pathway and related pathologies, highlighting the need for an integrated model.…”

Computational models of the neuromusculoskeletal system provide a deterministic approach to investigate input-output relationships in the human motor system. Neuromusculoskeletal models are typically used to estimate muscle activations and forces that are consistent with observed motion under healthy and pathological conditions. However, many movement pathologies originate in the brain, including stroke, cerebral palsy, and Parkinson’s disease, while most neuromusculoskeletal models deal exclusively with the peripheral nervous system and do not incorporate models of the motor cortex, cerebellum, or spinal cord. An integrated understanding of motor control is necessary to reveal underlying neural-input and motor-output relationships. To facilitate the development of integrated corticomuscular motor pathway models, we provide an overview of the neuromusculoskeletal modelling landscape with a focus on integrating computational models of the motor cortex, spinal cord circuitry, α-motoneurons and skeletal muscle in regard to their role in generating voluntary muscle contraction. Further, we highlight the challenges and opportunities associated with an integrated corticomuscular pathway model, such as challenges in defining neuron connectivities, modelling standardisation, and opportunities in applying models to study emergent behaviour. Integrated corticomuscular pathway models have applications in brain-machine-interaction, education, and our understanding of neurological disease.
