OVERVIEW
This database describes the synaptic connectivity of C. elegans,
and is the revision of the previous database (Oshio et al., 1998).
Sources of data are figures and tables in the two papers
(Albertson and Thomson, 1976; White et al., 1986).
Albertson and Thomson have described the synaptic connectivity among neurons
in the pharynx while White et al. have described that in the somatic
nervous system except the pharynx.
All those data are compiled in this database.
It consists of three parts each of which is equivalent to figures in the paper
of Albertson and Thomson, figures in the paper of White et al.
and tables in the same paper, respectively.
The database is constructed by CCeP[*] under the following policies.
-
There should be one-to-one correspondence between information
provided by the original papers and that described in various
files in the database.
-
The database should provide necessary information so that everybody
can reconstruct the illustration in the original papers up to topology.
-
The database should provide sufficient information for any user
to edit their own data file according to their peculiar request.
According to the policy (b), the geometrical information about the synapses
depicted in the original papers is incorporated in the database.
Although several ambiguous or questionable
descriptions have been found in the original papers, we have not corrected
those description.
Therefore the present data are just the same as those
in the original papers. Instead of correction, the policy (c) is employed.
The policy (c) is realized in the comment index to point out ambiguous or
questionable description in the original paper.
We leave users to decide how to treat those ambiguous or questionable description.
