Analysis of anatomical data in the original papers[1,2]
and improvement in this tool
[ English / Japanese ]
Several ambiguous or questionable descriptions are found in the original papers[1,2].
These descriptions are not improved in the database[3].
Instead of improvement, the comment indices "wf[1-33]", "wt[1-3]" and "af[1-15]" are attached to the corresponding data.
On anatomical data in the original papers[1,2],
detailed analysis is summarized in
the report[4].
Improvements of some erroneous descriptions
are proposed in the section 2 of the report.
When the synaptic connectivity is computed in this tool,
these improvements are adopted.
In addition, the followings are also adopted
according to the comment indices.
-
For "wf5" and "wf6",
particular attention is paid to avoid double-counting of gap junctions.
-
For "wf13",
the reference neuron of the half of the corresponding synapses is not RIPL, but RIPR.
-
For "wf25",
the partner neuron is not RMVDL, but RMDVL.
-
For "af1",
the synapse types of I2L and NSM[L,R] are "S"(Send),
and those of M4 and MC[L,R] are "M"(Muscle synapse).
-
For "af5",
the partner of the muscle synapse is decided according to the corresponding figure
in the original paper[2].
However this decision is very ambiguous.
