“…Beta oscillations (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) are an abundant phenomenon in the cortico-basal gangliathalamo-cortical network and have been associated with a wide range of potential functions, including feedback processing (Cao and Hu, 2016;Tan et al, 2016;Torrecillos et al, 2015), communicating sensorimotor information across widespread areas (Classen et al, 1998;Kilavik et al, 2013;Rubino et al, 2006), maintaining muscle synergies (Aumann and Prut, 2015), movement inhibition (Aron et al, 2016), timing (Kononowicz et al, 2019) as well as clearing out previously held information (Schmidt et al, 2019). However, if instead of assigning broad functions, we aim to link the phenomenon of these oscillations to taskspecific neural computations, such as coincidence detection or recurrent amplification (Carandini, 2012;Douglas et al, 1995), we need to understand in more detail how basal ganglia and cortical activity patterns are co-modulated.…”
