Single visual neurons code opposing motion independent of direction.
Cells in intermediate and deeper layers of the pigeon optic tectum respond best when a textured background pattern is moved in the opposite direction to a moving test spot. Complete inhibition occurs when the background moves in the same direction as the test stimulus. Most noteworthy is the invariance of this relationship over a wide range of test spot directions. These cells represent a highe...
متن کاملMotion transparency from opposing luminance modulated and contrast modulated gratings
Two luminance gratings of identical orientation and opposite directions of motion are seen as moving across one another (i.e. moving transparently) only if they differ in spatial frequency (SF) by a factor of four or more. Identical SF gratings produce counter-phase flicker. This suggests that opposite motions cancel each other at the level of motion detection. Here we show that motion transpar...
متن کاملUsing camera motion to identify types of American football plays
This paper presents a method that uses camera motion parameters to recognise 7 types of American Football plays. The approach is based on the motion information extracted from the video and it can identify short and long pass plays, short and long running plays, quaterback sacks, punt plays and kickoff plays. This method has the advantage that it is fast and it does not require player or ball t...
متن کاملAbi plays an opposing role to Abl in Drosophila axonogenesis and synaptogenesis.
Abl tyrosine kinase (Abl) regulates axon guidance by modulating actin dynamics. Abelson interacting protein (Abi), originally identified as a kinase substrate of Abl, also plays a key role in actin dynamics, yet its role with respect to Abl in the developing nervous system remains unclear. Here we show that mutations in abi disrupt axonal patterning in the developing Drosophila central nervous ...
متن کاملCerebellar vermis plays a causal role in visual motion discrimination.
Cerebellar patients have been found to show deficits in visual motion discrimination, suggesting that the cerebellum may play a role in visual sensory processing beyond mediating motor control. Here we show that triple-pulse online transcranial magnetic stimulation (TMS) over cerebellar vermis but not over the cerebellar hemispheres significantly impaired motion discrimination. Critically, the ...
