    The medial fronto-parietal network of the macaque: Different specializations for spatial parameters of reaching? by Marina De Vitis, Matteo Filippini, Kostas Hadjidimitrakis, Francesco Edoardo Vaccari, Stefano Diomedi, Michela Gamberini, Martina Gori, Michele Testa, Claudio Galletti, Patrizia Fattori

    Published 2025-09-01
    “…Therefore, it is unknown whether tuning by spatial and motor variables, such as reach direction and depth, is similar in frontal and parietal cortices and whether there are differences in the temporal evolution of activity that reflects functional specializations. To fill this gap, we recorded single-neuron activity from two regions of the medial fronto-parietal circuit in macaques performing an instructed delay reaching task toward targets varying in both direction and depth. …”
