... of superficial interneurons (SINs), a specific type of optic tectal neurons, in motion detection of larval zebrafish. SINs mainly receive excitatory synaptic inputs, exhibit transient ON- or OFF-type of responses evoked by light flashes, and possess a large receptive field (RF). One fifth of SINs are DS...

... functions of neural circuits. For instance, mechanisms of detecting visual motion are currently subject to intense behavioral, physiological and anatomical investigations in this species (reviewed in [ 5 , 6 ]). It has been nearly 60 years since an influential model of visual motion detection...

... contributes to form perception, then a ventral visual lesion should only impair motion perception when form representations are evoked (e.g. by structure-from-motion stimuli), but not when only basic motion perception is tapped (e.g. motion coherence or motion detection). Finally, if ventral cortex...

... of attention. attention direction change inferior parietal lobe MEG motion detection MT/V5 The human brain is equipped with a specialized system devoted to the processing of visual motion. Previous studies in humans have used a variety of visual stimuli and techniques in order to identify the motion...

Three accounts make different predictions about the location and timing of TMS effects over striate and extrastriate areas. According to the ‘microconsciousness...

... Inhibition Local delay Motion detection systems Pattern discrimination Nerve cells are the targets of many thousands of excitatory and inhibitory synapses. An extreme case are the Purkinje cells in the primate cerebellum, which receive between one and two hundred thousand synapses onto dendritic spines...

... flight. Further evidence that this involved motion vision came from the finding that the system the bees were using was colour-blind and sensitive only to green contrast. The motion-detecting system in bees is known to be sensitive only to green contrasts, unlike the trichromatic system usually involved...

...This chapter reviews how different areas of the primate brain act together to produce perception of visual motion. After a brief overview of motion pathways, the first section gives an overview of the elementary motion detection mechanisms in the primate visual system. The second section discusses...

In this chapter we turn to time. What is time? If we try to picture it, the natural thing to do...
