This dataset is composed of eight bilateral silicon-probe multi-cellular electrophysiological recordings performed on four male Long-Evans rats. These recordings were performed to assess the effect of novel spatial learning on hippocampal CA1 neural firing and LFP patterns in naïve animals. Each session consisted of a long (~4 hour) PRE rest/sleep epoch home-cage recordings performed in a familiar...

The data set contains multichannel simultaneous recordings made from layer CA1 of the right dorsal hippocampus of three Long-Evans rats during open field tasks in which the animals chased randomly placed drops of water or pieces of Froot Loops while on an elevated square platform. In order to examine the temporal relationships between theta oscillations and the coordination of neuronal firing in the...

This dataset contains recordings made using a silicon probe from three areas from a single rat that was performing different behavioral tasks. The three regions recorded from are left and right hippocampal CA1 and right entorhinal cortex. The tasks are a left/right alternate selection task, wheel running, and platform exploration. The neural data was recorded on 125 channels. In the study, five...

This dataset of multi single neuron recordings was acquired from three rats (EE, FF, GG) while they performed a working memory task. Neuronal activity was monitored simultaneously in the PFC (64 channels) and the intermediate CA1 (32 channels) of the hippocampus. In one rat (EE), sleep was also recorded before and after the task. The data was obtained during 52 main recording sessions and nine short...

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....

This data contains recordings from the rat frontal cortex (brain regions mPFC, OFC, ACC, and M2) during wake-sleep episodes where at least 7 minutes of wakefulness are followed by 20 minutes of sleep. The data was recorded using silicon probe electrodes in the frontal cortices of male Long Evans rats between 4-7 months of age during no specific behavior, task or stimulus. The animal was left alone...

Hippocampus has been involved in both cognitive and endocrine functions. This study measured electrophysiological activity from the hippocampus and interstitial glucose concentrations in the body of freely behaving rats to identify an activity pattern that may link these disparate functions of the hippocampus. For this study, they used adult Long Evans rats. During the experiment, rats were recorded...

Medial septum (MS) is important for theta generation by either a unitary pacemaker timing signal imposed on the hippocampal system or assisting in organizing target subcircuits within the phase space of theta oscillations. Therefore, this study used temperature manipulation of the MS to test these models. Long Evens rats were water restricted for 22 hours and trained to perform the behavioral task...

The function of hippocampal sharp-wave ripples (SPW-Rs) relate to the consolidation of recent experiences and planning of future actions. This study investigated the impact of SPW-Rs on the firing patterns of lateral septal (LS) neurons in behaving rats. The experiments were performed on Long-Evans rats. For this study, they examined the hippocampal-LS circuit by simultaneously recording activity patterns...

Several spatial coding mechanisms are known to coexist in the hippocampus. However, how are they influenced by various environmental features is still unclear. This study investigated the spatial coding characteristics of hippocampal neurons in mice and rats navigating in different environments. C57BL/6 mice and Long-Evans rats were used in this study. For both mice and rats, most CA1 cells were recorded...
