Depicted are neurons (yellow dots) within the macaque dorsomedial posterior parietal cortex (dmPPC), collectively orchestrating intricate processes crucial for episodic processing during naturalistic viewing. These neurons exhibit diverse spike patterns influenced by eight visual and behavioral categories represented in the videos (multicolored discs, varying in size to denote the extent of neuronal modulation by each category). The connecting lines illustrate the network relationships between neurons and categories. For a deeper understanding of how dmPPC neurons exhibit mixed selectivity coding during episodic experiences, see the article by Wang et al. Cover image: Lei Wang.
