Large-scale simultaneous recordings of single units from dorsal and ventral hippocampus in freely-behaving rats during a fear conditioning protocol

The data set contains large-scale simultaneous recordings of single units from the dorsal and ventral hippocampus in freely-behaving rats. The data were used to study how contextual and emotional information are integrated across the dorsoventral axis of the hippocampus. Results from the experiments are described in: Pompili*, Hamou* & Wiener (2026) Integration of fear learning and fear expression across the dorsoventral axis of the hippocampus. PNAS The data set includes 12 sessions, each consisting of 5 concatenated sub-sessions: preTask, task1, interTask, task2, postTask. Data include sorted spikes (times, clusters), freezing and resting periods (detected as in Pompili and Todorova (2022) Front. Neural Circuits) and sub-sessions beginning and end times. They are provided in the standard, open format of NeuroSuite (L. Hazan, http://neurosuite.sourceforge.net, see Hazan et al., 2006).
