2019, Clinical NeurophysiologyCitation Excerpt :It is also possible that the neural mechanisms for detecting a loss of balance are less efficient in AIS participants. Because theta oscillation synchronization is observed when participants lose their balance (Peterson and Ferris, 2018; Sipp et al., 2013; Varghese et al., 2014) and it is thought to be related to detection of balance changes (Hulsdunker et al., 2015a; Slobounov et al., 2013), less theta band synchronization in AIS participants would indicate impairments in detecting a sudden change in balance state-space. In addition, as synchronization in the gamma band in the sensorimotor cortex increases with performance during challenging sensorimotor tasks (Aoki et al., 1999; Fries, 2015), poorer balance control in AIS participants should imply gamma band desynchronization compared to controls.
Electroencephalographic Correlates of Continuous Postural Tasks of Increasing Difficulty
2018, NeuroscienceCitation Excerpt :However, Figs. 2 and 4 suggest a slight reduction in theta power during the postural tasks, with the exception of Cz. Given that theta oscillations are understood to be important during transient balance perturbations (Slobounov et al., 2009; Sipp et al., 2013; Slobounov et al., 2013; Varghese et al., 2014), a possible explanation for this discrepancy is that there are multiple, opposing event-sensitive changes in theta power that are not reflected in summary measurements of power in “steady-state”, continuous balance. Evidence exists to support this concept.
