Detailed Description

Reads in patterns from the database and applies them to the neurons in this task. Works using its own set of buffers to manage the delays of temporally smeared patterns. These buffers can advance independently of the time step so that the same pattern can be applied for several steps.

Temporal patterns are applied once and then a new pattern is applied after a number of timesteps. Fixed patterns are applied every time step.
