Visually-Guided Collective Behavior in Human Swarms

Behavior Fusion for Visually-Guided Service Robots

The neural basis of visually guided behavior.

A nimals see things and then act on the ft basis of what they see. What chain of events connects some key stimulus with a specific fixed pattern of responses? In recent years workers in several laboratories have sought by many different means to analyze the nerve mechanisms by which animals interpret sensory. signals and select the most ap­ propriate response. The most effective way to understa...

Insect - Inspired Vision and Visually Guided Behavior

Cortical temporal dynamics of visually guided behavior.

Little is known about the temporal dynamics of cortical activation during visually guided behavior. We measured changes in brain activity in human posterior parietal cortex (PPC) and premotor cortex (PMC) during saccades and visually guided reaching using magnetoencephalography (MEG) and novel time-frequency reconstructions of MEG (tfMEG) data. Results indicate that early high-gamma activity ov...

Cellular mechanisms for integral feedback in visually guided behavior.

Sensory feedback is a ubiquitous feature of guidance systems in both animals and engineered vehicles. For example, a common strategy for moving along a straight path is to turn such that the measured rate of rotation is zero. This task can be accomplished by using a feedback signal that is proportional to the instantaneous value of the measured sensory signal. In such a system, the addition of ...
