Catacomb 2 Examples
The examples are in roughly increasing order of complexity. The
first two sections on the workbench and lab equipment are necessary to
understand the rest but after that the order is less important.
-
Workbench Basics. How to build models with
the workbench - different operating models, component sets, setting
parameters and displaying results.
-
Lab Equipment.Generating and recording
continuous signals and spikes.
-
Integrate and Fire Cell Models. Adding
properties to a simple integrator to make progressively more subtle
cell models.
-
Grouping and Reusing Components. Perhaps the
most important feature if Catacomb 2 is its ability to group
components and connections into new types of processing unit. These
can then be used exactly like the elementary components. This way you
can build structured hierarchical models without any duplication of
effort.
-
Animats Virtual Environments. Walls, sound sources,
food dispensers et al. for setting up a behavioral experiment;
Sensors and effectors for building a "robot" to experiment on.
-
Synapses. Spikes arriving at a synapse
trigger processes leading to conductance changes in the post-synaptic cell.
These can be modeled at a variety of levels in Catacomb, including
timing dependent plasticity functions and transmission modulation by
external agents.
-
Membrane Channels. In Catacomb2
integrate-and-fire models merge smoothly into channel-based
models. You can mix and match components according to the behavior you
want to study.
-
Accessing the CoCoMac database. Catacomb2
includes an experimental interface to the CoCoMac database of
connectivity in the macaque.
-
Spike Routing
The spike routing mechanism is still under development.
