This dataset contains the waveforms of dentate spikes extracted from the local field potential (sampled at 1 kHz) of the dorsal hippocampal formation of 8 mice using linear probes. These animals were subjects of research across three different laboratories, and the raw data from these recordings have been previously analyzed in distinct original studies. For comprehensive information, consult the relevant publication linked below.

Each file within this dataset corresponds to the data collected from a single animal and is structured as a 3D matrix of channels by dentate spikes by amplitude samples. Each dentate spike is composed of 401 amplitude samples centred at the peak, with each sample representing a one-millisecond time bin. I.e., being the DS peak at t=0, the time window ranges from −200 to 200 ms. The number of channels varies according to the linear probe used in each mouse. The index of the channel in hilus, which was chosen for the DS detection, is indicated below:

Mouse A   (reference 4) – channel index   8
Mouse B1 (reference 3) – channel index 31
Mouse B2 (reference 2)– channel index 25
Mouse B3 (reference 2)– channel index 30
Mouse C1 (reference 1)– channel index 15
Mouse C2 (reference 1)– channel index 27
Mouse C3 (reference 1)– channel index 26
Mouse C4 (reference 1)– channel index 31

We welcome researchers wishing to reuse our data to contact the creators of datasets. If you are unfamiliar with analysing the type of data we are sharing, have questions about the acquisition methodology, need additional help understanding a file format, or are interested in collaborating with us, please get in touch via email. Our current members have email addresses on our main site. The corresponding author of an associated publication, or the first or last creator of the dataset are likely to be able to assist, but in case of uncertainty on who to contact, email Ben Micklem, Research Support Manager at the MRC BNDU.

Dentate spike waveforms: Each panel shows the local field potential of each linear probe channel across the dentate gyrus of mouse A during the occurrence of a dentate spike within a 400-ms window around the peak. Dentate spikes are detected from the channel located at the hilus highlighted in black.
