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 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 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...

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...

The investigators collected simultaneous recordings using multi-channel electrode arrays attached to the prearcuate gyrus of macaque monkeys who performed a direction discrimination task with fixed stimulus duration. In the study, 96-channel multielectrode arrays were used to record from neural populations in area 8Ar of the prearcuate gyrus of three macaque monkeys, while they performed a direction...

This study created an experimental model to assess the effects of early-life exposures to antibiotics on the intestinal microbiota and gene expression in the brain. For this study, C57BL/6 mice were breed for 5 days and the pregnant dams were randomized into 3 treatment groups. First group was treated with low-dose penicillin G in their drinking water starting during the last week of pregnancy and...

The investigators conducted experiments with seven macaque monkeys to understand how measures of neural activity in the lateral intraparietal (LIP) cortex corresponded with decision-making as they performed different tasks: a motion discrimination task and two variations on a novel face categorization task where subjects reported the faces' species or expression. They found that neuron firing rates...
