Usage

Place cell

The vmpc object contains information about a cell's encoding of space. To create it, navigate to the cell directory and instantiate the object

cd <cell directory>
vmp = vmpc('auto');

where <cell directory> should be replaced by an actual directory, e.g. "session01/array01/channel001/cell01". To plot a smoothed version of the cell's place field, run

plot(vmp, 1, 'MapOnly')

This should pop-up a figure contained the smoothed place field of this cell, i.e. a map of the locations in the maze where this cell's spikes predominantly occured.

To show the unsmoothed, raw map, run

plot(vmp,1,'MapOnly','Smooth',0)

View cell

A view cell encodes information about what the subject is looking at. We compute the view represention of a cell by creating a vmsv object.

cd <cell directory>
vmv = vmsv('auto','Prefix','1');

We can get a 3D representation of the view information contained in this cell by doing

plot(vmv, 'plotmap')

This should pop-up a so-called exploded view, showing the density of spikes elicited when the subject looked at the walls, the pillars, the floor and the ceiling.

Head direction cell

A head direction cell encodes the head direction of the animal. We compute the head direction tuning of a cell by creating a vmhd object.

cd <cell directory>
vmh = vmhd('auto')

We plot the object using

plot(vmh)
