Stimuli Description
Stimuli can be applied to a number of different objects in AnimatLab. Each object knows what type of stimuli that can be applied to it
and will only provide you with those for options when adding stimuli. For example, you can only add current stimuli to neurons, and only
force stimuli to rigid bodies. To add a stimulus you need to select the desired object and then hit the Add Stimulus button,
 , on the toolbar.
Alternately, once the item is selected you could right-click to display the pop-up menu and then select the Add Stimulus item. Either way,
This will open the Add Stimulus Dialog. Only the stimuli that can be added to this object will be
available. Choose the one you want and a new
stimulus will be added to the list in the project workspace, and you can configure the properties for the new stimulus in the properties toolbar.
The following is a list of the currently available stimuli.
1. |
Current Stimuli |
|
 |
|
|
|
Applies a tonic current stimulus to a neuron. |
|
 |
|
|
|
Applies a current stimulus that alternates between an on and off states for a given amount of time. |
|
 |
|
|
|
A current is applied in bursts. A burst alternates on and off for a given duration of time. Within the burst
the current toggles on and off with a fixed duration. |
|

|
This is used to simulate gamma motor co-activation used during
locomotion. It uses predicted movements
and the inverse muscle dynamics equations to calculate a current stimulus that will allow a stretch receptor
to maintain a constant Type Ia fiber firing rate during a predicted movements. |
2. |
Body Stimuli |
|
 |
|
|
|
Forces a motor to rotate at a set velocity for a specified amount of time. |
|
 |
|
|
|
Applies forces and torques to a body part. |
|
 |
|
|
|
Enables or disables a part that can be enabled. |
|
 |
|
|
|
Uses a PID controller to maintain a specified rotation of a joint by applying restorative forces. |
