Load projection into motif

This function loads a projection schema into a motif object. Projections define internode connectivity within a network built using the motif.

Usage

load.projection.into.motif(
  motif,
  presynaptic_layer,
  postsynaptic_layer,
  projection_conductance = 0.1,
  presynaptic_type = "principal",
  postsynaptic_type = "principal",
  max_col_shift_up = 0,
  max_col_shift_down = 0,
  max_pch_shift_up = 0,
  max_pch_shift_down = 0,
  hem_shift = 0L,
  via_apical = FALSE
)

Arguments

motif

Motif object into which to load the projection.

presynaptic_layer

Character string giving layer of presynaptic neuron, e.g. "L1", "L2", "L3", "L4", etc.

postsynaptic_layer

Character string, or vector of character strings, giving layer of postsynaptic neuron.

projection_conductance

Numeric giving overall strength of the projection, as expected synaptic conductance (nS, default: 0.1).

presynaptic_type

Character string giving type of presynaptic neuron (default: "principal").

postsynaptic_type

Character string giving type of postsynaptic neuron (default: "principal").

max_col_shift_up

Maximum number of columns upwards (increasing columnar indexes) that the projection can reach (default: 0, should be positive integer).

max_col_shift_down

Maximum number of columns downwards (decreasing columnar indexes) that the projection can reach (default: 0, should be positive integer).

hem_shift

Hemisphere shift for the projection: 0 = same hemisphere (default), 1 = contralateral hemisphere. Ignored when the network has only one hemisphere.

Value

The updated motif object with the new projection loaded.
