Controlling Visually Guided Behavior by Holographic Recalling of Cortical Ensembles

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...

The cortical control of visually guided grasping.

People have always been fascinated by the exquisite precision and flexibility of the human hand. When hand meets object, we confront the overlapping worlds of sensorimotor and cognitive functions. The complex apparatus of the human hand is used to reach for objects, grasp and lift them, manipulate them, and use them to act on other objects. This review examines what is known about the control o...

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...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
