Concatenates trees in cell array of trees intrees
with electrical synapses and calculates
the steady state electrotonic matrix
(sse,
see “sse_tree”).
Indices of connected nodes
(inodes1 to inodes2)
accumulative along trees.
gelsyn assigns conductance values to each gap junction.
I is as in “sse_tree”.
Example:
we reproduce a simplified dendritic network similar as in
(Cuntz H, Haag J, Borst A 2003 PNAS 100(19):11082-5).
Connect all nodes from one tree to another one
and inject a current in the dendrite of one tree:
>> tree = hsn_tree;
>> sse = ssecat_tree ({tree tree},
(1:1290)', (1291:2580)', .01, 15, 'none');
The resulting potential spread is smaller in the tree where the current was injected, than in the neighbour: the dendritic network leads to spatial blurring, as is used in some fly interneurons to process motion-based images:
