Mailing list

Project team round

Here we discuss topics that need broader attention, for example questions that came up but are outside a single project's scope, larger planned changes/PRs that affect all teams or pending work that is blocked by external factors.

Go to the Project boards.

In-depth discussion

Numerical integration in neuron models (NESTML)

Grid based integration and precise timing cause models to reach spike threshold at different times

  • Q: should we expect robust timing?
  • Q: should we expect non-linar models to behave different?

Tri-partite semantics (astrocyte models)

Semantics of conditional probability p_cond may be confusing (see Connection specifications) as cond usually indicates conductance based models

Possible alternatives

  • p_syn_third
  • p_primary_third
  • p_third Or even more verbose
  • p_neuron_connection_with_third
  • p_conditional_third
  • p_third_if_primary (DECISION)

Accessing parameters of compartmental models

How can we gain access to setting parameters in specific compartments (see discussion here)?

  • Which would be the best way to implement? Does something similar already exist in other areas?
