“…It has been suggested that hippocampal theta is actually linked to attention and arousal (Jacobs, Lega, & Watrous, 2017). This type of theta has been linked to sensorimotor functions (Bland & Oddie, 2001;Burgess, Barry, & O'Keefe, 2007;Ekstrom et al, 2005;Hoffman et al, 2013;Jacobs et al, 2017;Lopour, Tavassoli, Fried, & Ringach, 2013;Mormann et al, 2005;Watrous, Fried, & Ekstrom, 2011), spatial navigation (Aitken, Zheng, & Smith, 2018;Ekstrom et al, 2005;Jacobs et al, 2017;Kahana, Sekuler, Caplan, Kirschen, & Madsen, 1999;Vass et al, 2016;Watrous et al, 2011), episodic memory coding (Jacobs et al, 2017), and, of particular interest, head position all through its connection to the vestibular system (Aitken et al, 2018).…”
