This dataset was collected for a study to replicate previous work on hippocampal physiology predictive of successful encoding using an associative memory paradigm in a surgical intracranial electroencephalography (iEEG) group and extend those investigations to a chronic ambulatory iEEG population using RNS System devices (NeuroPace, Inc.). The primary objective was to compare the hippocampal gamma...

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 dataset contains x, y, and z trajectories of single GABAergic synaptic vesicles that we obtained by labelling GABAergic synaptic vesicles with streptavidin-coated QDs to commercially available biotinylated antibodies against the luminal domain of the vesicular GABA transporter (VGAT) and tracking the real-time three-dimensional position of single GABAergic synaptic vesicles up to the moment of...

Electrophysiological recordings were obtained from male rats who were subjected to localized cooling of their medial septum (MS) prior to completing behavioral tasks. The MS is critical in theta generation. Therefore, temperature manipulation of the MS was used to test these models. Approximately 40 control trials were completed, followed by exposure to dry ice to reduce MS temperature for 20 to 60...

This study profiled neurotrophin and neurotrophin receptor gene expression within microdissected CA1 neurons along with regional hippocampal dissections from participants in the Rush Religious Orders Study (RROS). The RROS participants included older religious clergy who have agreed to medical and psychological evaluation each year and brain donation after death. This study began in 1993 and has enrolled...

This study investigated whether the Alzheimer’s disease (AD) pathological lesions diffuse plaques (DPs), neuritic plaques (NPs), and neurofibrillary tangles (NFTs). For this study, downregulation of brain-derived neurotrophic factor (BDNF) and its cognate neurotrophin receptor, TrkB, were observed during the progression of dementia. They performed negative binomial (NB) regressions using gene expression...
