Extracellular recordings and juxtacellular labelling with glass electrodes in the mouse medial septum and hippocampus
<p>This repository contains MAT files consisting of simultaneously recorded mouse medial septal and hippocampal local field potentials (20 kHz sampling rates) and spikes from single medial septal cells. Data were recorded with glass electrodes during spontaneous movement and rest periods, followed by juxtacellular labelling of the medial septal cell. Text files of the spike times and detected hippocampal CA1 theta (5-12 Hz) oscillation trough times are associated with each MAT file.</p> <p>The files are organised by cell (neuron) name. For further details, see the CSV file included with the dataset. These recorded and labelled single cells were originally reported in Joshi et al 2017, Viney et al 2018, and Salib et al 2019.</p> <p>Each MAT file contains the following channels, exported from the original Spike2 (smr) recording files:</p> <p>(1) Details of the recording</p> <p>(2) Detected spikes (in seconds) from the single medial septal cell</p> <p>(3) Movement detection (eg. accelerometer or rotary encoder)</p> <p>(4) Local field potential (medial septum), in mV</p> <p>(5) Local field potential (hippocampal CA1), in mV; see CSV file for precise location (e.g. within stratum pyramidale)</p> <p>This dataset is made available under a Creative Commons Attribution 4.0 International (CC BY 4.0) license: If you share or adapt these data you must give appropriate credit, provide a link to the license, and indicate if changes were made.</p>
Extracellular recordings from a locust (Schistocerca americana) antennal lobe.
<p>Raw data from a tetrode recording from the antennal lobe (the first olfactory relay) of a locust, Schistocerca americana.</p> <p>The data were filtered (before A/D conversion) between 300 and 5000 Hz and sampled at 15 kHz. See Pouzat, Mazor and Laurent (2002) Journal of Neuroscience Methods 122(1): 43--57 for recording details. The data were recorded with a "Michigan probe", now sold by NeuroNexus (http://neuronexus.com/). A picture of the probe--made of 16 channels making 4 tetrodes--can be seen on slide 3 of DOI:10.5281/zenodo.14660. Good data were visible only on one of the tetrodes made of channel 9 / 11 / 13 / 16 and only data from these channels were recorded. The "LabBook" attribute contains transcript of the actual lab book with details about the acquisition. In short: 1 hour and 40 minutes of spontaneous activity was recorded as well as responses to 150 stimulation with citral.</p> <p>Each data set has a "log_file_content" attribute containing a copy of actual log file automatically generated during the acquisition. The stimulation protocol as well as the precise times of beginning and end of trial acquisition can be found there.</p> <p>The data are in HDF5 format (http://www.hdfgroup.org/HDF5/).</p> <p>Recordings performed by Christophe Pouzat and Ofer Mazor in the laboratory of Gilles Laurent (California Institute of Technology) in February 2001.</p>
Extracellular recordings from the locust, Schistocerca americana, olfactory pathway
<p>This depository contains raw data from 14 experiments performed on adult locusts. The data are contained in HDF5 files (http://www.hdfgroup.org/HDF5/). They are stored as compressed integers coded on 16 bits as they came out of the A/D card. Recording details can be found in Pouzat, Mazor and Laurent (2002) Using noise signature to optimize spike-sorting and to assess neuronal classification quality. <em>Journal of Neuroscience Methods</em> <strong>122</strong>: 43-57 (a pre-print version is available: http://xtof.perso.math.cnrs.fr/pdf/Pouzat+:2002.pdf). Each data file is subdivided in Groups corresponding the type of acquisition performed: one or several epochs of spontaneous activity recording; repetitive stimulation with a given odor. Each group is made of one (if say a single epoch of 60 seconds of spontaneous recording was made) or several (if say 100 stimulation with Citral were made) (sub-)groups containing the data of all the channels that were recorded during that epoch. Each of these sub-groups is made of 4 to 16 data sets: 1 dimensional arrays containing the raw data recorded from one of the 16 channels of our probe (made of 4 tetrodes) during a single acquisition epoch. All channels were sampled at 15 kHz. Each data file has attributes (metadata) README and LabBook. The first, README contains a shortened version of the present text; the second, LabBook contains a transcript of the lab book corresponding to the experiment. Most groups have a log_file_content attribute. This attribute contains a copy a text file that was automatically generated during data acquisition. Some recording details can be found there as well as the precise time and data of each recorded epoch. The data were kept for 14 years on CDs and about a third of the recordings got lost because of CD corruption! What's left still make 15 GBytes of data after compression: a substantial amount. This CD corruption explains why some groups don't have a log_file_content attribute: it was on a corrupted CD.</p> <p>Of the 14 experiments, 12 contain antennal lobe (the first olfactory relay of insects) recordings, 1 contains antennal lobe and alpha lobe recordings and 1 contains only alpha lobe recordings. Here the alpha lobe location should be taken with a little bit of caution since the latter is not as easy to locate as the antennal lobe in the locust. All data files start with the locust prefix, followed by the experiment year, month and date, like locust20000214.hdf5 an experiment performed on February 14 2000. Due to file size restriction on Zenodo, two experiments are split into two data files: locust20010124b_part1.hdf5 and locust20010124b_part2.hdf5 as well as locust20010214_part1.hdf5 and locust20010214_part2.hdf5. On two dates, two different experiments were performed: locust20010124a.hdf5 and locust20010124b_part1.hdf5 / locust20010124b_part2.hdf5 as well as locust20010208a.hdf5 and locust20010208b.hdf5. When a stimulation was applied, the following code is used: Odor name / Number of stimulation / Inter-stimulation interval / duration before the odor pulse / odor pulse duration / post pulse duration [odor dilution when several dilutions were used]. All times are in seconds.</p> <p>A very brief description at the group level of the files content follows (see the LabBook attribute of each individual file for details):</p> <ol>

Datasets for neuronal imaging, extracellular recordings and behavioral rig code
<p>Rod and cone photoreceptors degenerate in retinitis pigmentosa (RP). While downstream neurons survive, they undergo physiological changes, including accelerated spontaneous firing in retinal ganglion cells (RGCs). Retinoic acid (RA) is the molecular trigger of RGC hyperactivity, but whether this interferes with visual perception is unknown. Here we show that inhibiting RA synthesis with disulfiram, a deterrent of human alcohol abuse, improves behavioral image detection in vision-impaired mice. <i>In vivo</i> Ca<sup>2+</sup> imaging shows that disulfiram sharpens orientation-tuning of visual cortical neurons and strengthens fidelity of responses to natural scenes. An RA receptor inhibitor also reduces RGC hyperactivity, sharpens cortical representations, and improves image detection. These findings suggest that photoreceptor degeneration is not the only cause of vision loss in RP. RA-induced corruption of retinal information processing also degrades vision, pointing to RA synthesis and signaling inhibitors as potential therapeutic tools for improving sight in RP and other retinal degenerative disorders.</p>
