Manipulating heterogeneity of GJ connectivity as a graph-theoretical
degree distribution.

9342c468 14 Nov 2012 17:20 Eugenio Piasini

Added plotting script for single cell current-voltage relationship.

99d61954 02 Nov 2012 18:06 Eugenio Piasini

Coupling strength simulation and plotting scripts.

bacefb30 02 Nov 2012 11:55 Eugenio Piasini

Added current-voltage relation plotting script.

The current-voltage relation (and, consequently, the input resistance)
doesn't seem to exhibit any significant heterogeneity induced by the
gap junction distribution.

baa3f2d5 01 Nov 2012 17:06 Eugenio Piasini

Added simulation script for input resistance heterogeneity analysis.

Analysis and plotting script is still to be implemented.

a93bb2d0 30 Oct 2012 17:10 Eugenio Piasini

Added network (de)synchronisation analysis as in Vervaeke2010.

Two new simulation configurations, network_desynchronisation and
network_desynchronisation_2010gap, try to reproduce the
desynchronisation effect reported in Vervaeke2010. The expected
behaviour seems to emerge only if the gap junction connectivity is...

Fixed missing GJ netconn and generally improved GJs for reduced model.

Now the first segment of the apical dendrites in the reduced model is
considered as being still in the molecular layer. This is to better
reproduce the choices made for the detailed model, and it plays an...

Rate-coded I/O analysis for parallel fibre input, with gap junctions.

f2b34742 22 Oct 2012 17:01 Eugenio Piasini

Rate-coded I/O analysis for mossy input, with gap junctions.

The gap junctions, the network and the stimuli are implemented as in
Vervaeke2012, except for heterogeneity. The detailed cell model
replicates the results in the paper, and the simplified one seems to...

acde1c0f 19 Oct 2012 17:05 Eugenio Piasini

Renamed FI curve script. Added FI results plot to the repo.

3e544529 19 Oct 2012 16:46 Eugenio Piasini

Another attenuation estimate (same cells, new random probe placement).

The agreement between the models is good, and they are both quite
close to the 52 micron experimental estimate in Vervaeke2012, figure
3C.

bc34809f 19 Oct 2012 16:32 Eugenio Piasini

Updated attenuation result with latest version of the model.

cf60a065 19 Oct 2012 16:30 Eugenio Piasini

Deleted old version of attenuation scripts and renamed the 'good' one.

The version that got deleted was confusing, as it wasn't immediately
clear that it didn't have anything to do with the results in
Vervaeke2012. Also, accordingly renamed the figure showing the...

164d52d6 19 Oct 2012 16:11 Eugenio Piasini

Updated attenuation analysis to work with the latest model version.

Also, added some comments to make clearer which script is the one to
be used to benchmark the model's behaviour against Koen's paper.

7753d4ac 19 Oct 2012 14:13 Eugenio Piasini

Reduced the basolateral dendrites' size.

This results in a better match for rate-coded I/O relationship for
mossy fiber stimulation, but on the other hand the cell is now
responding too much to apical stimulation. Also, the spike shape is
less bad (the size of the little after-spike hump has decreased).

d73fea17 19 Oct 2012 12:05 Eugenio Piasini

Enabled effective remote simulation for fi curve script.

59cfe776 18 Oct 2012 17:01 Eugenio Piasini

Added: rate-coded I/O comparison (Vervaeke, Solinas and reduced).

Added various relevant scripts and nC project elements. Note that the
existing nework connections in the nC project have been renamed, and
this might have broken some of the old scripts.

At this point, the results of the rate-coded I/O relationship are:...

06738eeb 10 Oct 2012 17:09 Eugenio Piasini

Updated segment groups.

7fc90769 10 Oct 2012 17:08 Eugenio Piasini

Raised the simulation temperature to 30 degrees.

16aa0183 05 Oct 2012 16:51 Eugenio Piasini

Rotated reduced model so that it points in the correct direction.

e63f5a81 27 Sep 2012 12:13 Eugenio Piasini

Minor simulation/plotting improvements.

Added plotting of detailed model's potential in spontaneous firing
simulation, and aligned the stimulation points for the detailed cell
in attenuation.py so that they match those that I'm forced to use in
the simplified cell.

5e176f77 24 Sep 2012 18:29 Eugenio Piasini

Fixed 'double spike' bug caused by on old KBK channel implementation.

This is a well-known problem with an old version of the mod file for
the KBK channel, and had been squashed somewhere else (at least in the
original model by Solinas - see relevant files on ModelDB and Open...

Formatting: preparing to modify KBK channel.

b416e467 24 Sep 2012 14:57 Eugenio Piasini

Modified axon and bl dendrites. Looking better.

Things that have improved:
- resting potential (closer to Koen's model)
- somatic response to single synaptic input on a dendrite (closer to
Koen's model, but still a bit too weak)
- spike shape (actually starting to look as "halfway between" Koen's...

Making larger changes in morphology beyond the apical dendrites.

I managed to get the dendritic attenuation length to match between the
models, but the absolute response properties of the cell to synaptic
input are still quite different (Koen's model is more reactive to...
