The sample includes conjunctive cells and head direction cells from layers III and V of medial entorhinal cortex and have been published in
|
|
Sargolini et al. (Science, 2006).
|
|
|
|
The files are in matlab format. They include spike and position times for recorded cells from rats that were running in a 1 x 1 m
|
|
enclosure. The cells were recorded in the dorsocaudal 25% portion of the medial entorhinal cortex. Position is given for two LEDs
|
|
to enable calculation of head direction.
|
|
|
|
The cell id is based on tetrode number and cell number (i.e: t2c7).
|
|
|
|
The file naming convention is as follow:
|
|
|
|
Rat number - session number _ cell id (i.e: 11084-03020501_t2c1).
|
|
|
|
Each session duration is normally 10 minutes, but some sessions are combination of 2 or more 10 minutes sessions, this is marked in
|
|
the file name by using "+" between the session numbers (i.e: 11207-21060501+02_t6c1). Note that the 6 first digits in the session
|
|
number is the date of the recording.
|
|
|
|
When loading the files into Matlab you get the following variables:
|
|
|
|
x1 Array with the x-positions for the first tracking LED.
|
|
y1 Array with the y-positions for the first tracking LED.
|
|
x2 Array with the x-positions for the second tracking LED.
|
|
y2 Array with the y-positions for the second tracking LED.
|
|
t Array with the position timestamps.
|
|
ts Array with the cell spike timestamps.
|
|
|
|
The position data have been smoothed with a moving mean filter to remove tracking jitter.
|
|
|
|
|
|
You can use the data for whatever you want but we take no responsibility for what is published!
