Purpose: To establish if visual feedback and force requirements influence SICI.
Methods: SICI was assessed from 10 healthy adults (5 males and 5 females aged between 21 and 35 years) in three submaximal isometric elbow flexion torque levels [5, 20, and 40% of maximal voluntary contraction (MVC)] and with two tasks differing in terms of visual feedback. Single-pulse and paired-pulse motor-evoked potentials (MEPs), supramaximal M-wave, and background surface electromyogram (sEMG) were recorded from the biceps brachii muscle.
Results: Repeated measures MANOVA was used for statistical analyses. Background sEMG did not differ between tasks (F = 0.4, P = 0.68) nor was task × torque level interaction observed (F = 1.2, P = 0.32), whereas background sEMG increased with increasing torque levels (P = 0.001). SICI did not differ between tasks (F = 0.9, P = 0.43) and no task × torque level interaction was observed (F = 2.3, P = 0.08). However, less SICI was observed at 40% MVC compared to the 5 and 20% MVC torque levels (P = 0.01–0.001).
Conclusion: SICI was not altered by performing the same task with differing visual feedback. However, SICI decreased with increasing submaximal torque providing further evidence that SICI is one mechanism of modulating cortical excitability and plays a role in force gradation.

Maturation changes the excitability and effective connectivity of the frontal lobe : A developmental TMS-EEG study
Määttä, Sara; Säisänen, Laura; Kallioniemi, Elisa; Lakka, Timo A.; Lintu, Niina; Haapala, Eero; Koskenkorva, Päivi; Niskanen, Eini; Ferreri, Florinda; Könönen, Mervi (John Wiley & Sons, Inc., 2019)The combination of transcranial magnetic stimulation with simultaneous electroencephalography (TMS–EEG) offers direct neurophysiological insight into excitability and connectivity within neural circuits. However, there ... -
Identification of Proprioceptive Thalamocortical Tracts in Children : Comparison of fMRI, MEG, and Manual Seeding of Probabilistic Tractography
Jaatela, Julia; Aydogan, Dogu Baran; Nurmi, Timo; Vallinoja, Jaakko; Piitulainen, Harri (Oxford University Press (OUP), 2022)Studying white matter connections with tractography is a promising approach to understand the development of different brain processes, such as proprioception. An emerging method is to use functional brain imaging to select ... -
Tracking the corticospinal responses to strength training
Mason, Joel; Frazer, Ashlyn K.; Avela, Janne; Pearce, Alan J.; Howatson, Glyn; Kidgell, Dawson J. (Springer, 2020)Purpose The motor cortex (M1) appears to be a primary site of adaptation following both a single session, and repeated strength-training sessions across multiple weeks. Given that a single session of strength-training is ... -
Corticospinal and intracortical excitability is modulated in the knee extensors after acute strength training
Alibazi, Razie J.; Frazer, Ashlyn K.; Pearce, Alan J.; Tallent, Jamie; Avela, Janne; Kidgell, Dawson J. (Routledge, 2022)The corticospinal responses to high-intensity and low-intensity strength-training of the upper limb are modulated in an intensity-dependent manner. Whether an intensity-dependent threshold occurs following acute strength ... -
