Active vision dynamically refines spatiotemporal neural representations, optimising visual processing through scanning behaviour and non-associative learning, providing insights into efficient sensory ...

Humans are innately capable of recognizing other people they have seen before. This capability ultimately allows them to ...

A notable aspect of peripheral responses in the animal nervous system is localization, where the linear receptive fields of simple-cell neurons respond to specific, contiguous regions much smaller ...

How that visual “clutter” affects visual processing in the brain, however, is not well understood. In a new study published Oct. 22 in the journal Neuron , Yale researchers show that this clutter ...

Zoccolan continues: “The neurons at the initial stages of our visual system are sensitive to the presence of visual stimuli in a very small part of the visual field (their “receptive field”). “This ...

In the primate visual system, it is thought that non-linearities such as exponentiation and normalization can accentuate response differences ... The Gaussian gain also caused units to shrink and ...

Receptive fields have been identified for the visual system, auditory system and somatosensory system, so far. For more information, see the following related content on ScienceDaily: Related Stories ...

To find out, the researchers created a model of the visual cortex that had different levels of neurons with receptive fields of increasing size. They then simulated an evoked memory by sending a ...

One theory about why the visual system is arranged hierarchically is that it helps with object recognition. If receptive fields were tiny, the brain would need to integrate more information to make ...
