“…A growing number of fMRI studies has primarily focused on revealing which brain regions support the implementation of novel task sets (Demanet et al, 2016;González-García, Arco, Palenciano, Ramírez, & Ruz, 2017;Hartstra, Kühn, Verguts, & Brass, 2011;Hartstra, Waszak, & Brass, 2012;Ruge & Wolfensteller, 2010) and, more recently, on characterizing implementation-specific neural representations (Bourguignon, Braem, Hartstra, De Houwer, & Brass, 2018; González-García, Formica, Wisniewski, & Brass, 2019;Muhle-Karbe, Duncan, De Baene, Mitchell, & Brass, 2017;Palenciano, González-García, Arco, Pessoa, & Ruz, 2019;Ruge, Schäfer, Zwosta, Mohr, & Wolfensteller, 2019). These results consistently point towards a crucial role of frontoparietal regions, and in particular of the prefrontal cortex (PFC).…”
