“…At the cellular level, multiple cell types have been identified to encode position, head direction, speed and other spatial variables in the rodent HF (Hafting et al, 2005; McNaughton et al, 1983; O’Keefe and Dostrovsky, 1971; Taube et al, 1990), some with 3D properties (Angelaki et al, 2020; Grieves et al, 2020), that has also been found in the bat HF (Finkelstein et al, 2015; Yartsev and Ulanovsky, 2013). Recent studies have employed multimodal models to reveal multiplexed representations in the rodent HF (Hardcastle et al, 2017; Laurens et al, 2019; Ledergerber et al, 2020). A fundamental advantage of such models is that they can correctly identify multimodal responses even for variables that are correlated and interdependent, while proved remarkably immune to pitfalls such as overfitting; whereas traditional methods often fail to quantify neurons with mixed selectivity (Laurens et al, 2019).…”
