Extracellular recordings from multi-site silicon probes in the anterior thalamus and subicular formation of freely moving mice.

The data set contains recordings made from multiple anterior thalamic nuclei, mainly the antero-dorsal (AD) nucleus, and subicular areas, mainly the post-subiculum (PoS), in freely moving mice. Thalamic and subicular electrodes yielding high number of the so-called Head-Direction (HD) cells were likely to be located in the AD nucleus and the PoS, respectively. Electrode placement was confirmed by histology. The data was obtained during 42 recording sessions and includes responses of 720 neurons in the thalamus and 357 neurons in the PoS, in seven animals while they foraged for food in an open environment (53- x 46-cm).

本数据集包含自由活动小鼠的多脑区神经放电记录，采集自丘脑前核群（anterior thalamic nuclei），其中以前背侧核（antero-dorsal nucleus，AD）为主；同时采集自下托亚区，主要为后下托（post-subiculum，PoS）。可记录到大量头部方向（Head-Direction，HD）细胞的丘脑电极与下托电极，分别对应AD核与PoS脑区。电极植入位置已通过组织学方法验证。本数据集来自42次记录会话，涵盖7只小鼠在53×46 cm开放环境中觅食时的神经活动数据：其中丘脑脑区共记录720个神经元的放电活动，后下托脑区则记录357个神经元的放电活动。
