| Learning | For example, in most studies of monkey vision, a visual stimulus appears if the animal directs gaze to a fixation point . |
| Saccade/antisaccade task | This was followed by a memory delay of two time steps during which only the fixation point was Visible. |
| Saccade/antisaccade task | 2B) represented the color of the fixation point and the presence of the peripheral cues. |
| Saccade/antisaccade task | 2D (upper row) was active as long as the fixation point was present and switched off when it disappeared, thus cueing the model to make an eye movement. |
| Using AuGMEnT to simulate animal learning experiments | All tasks have a similar overall structure: the monkey starts a trial by directing gaze to a fixation point or by touching a response key. |
| Using AuGMEnT to simulate animal learning experiments | We encouraged fixation (or touching the key in the vibrotactile task below) by giving a small shaping reward (r,, 0.2 units) if the model directed gaze to the fixation point (touched the key). |
| Unicellular dynamics | Following the usual practice in the analysis of dynamical systems, we study the basic properties of equations (11), such as fixed points and linear stability analysis, to analyze the key features leading to heterocyst differentiation. |
| Unicellular dynamics | First, we look at the fixed points of qa and qr for each pair of values of qs and q” |
| Unicellular dynamics | The fixed points on the lower and upper branches are always stable (blue region in Fig. |
