Context Matters: The Illusive Simplicity of Macaque V1 Receptive Fields [PDF]
, 2012 Even in V1, where neurons have well characterized classical receptive fields (CRFs), it has been difficult to deduce which features of natural scenes stimuli they actually respond to.

A neurodynamical model of brightness induction in V1 [PDF]
, 2013 Brightness induction is the modulation of the perceived intensity of an area by the luminance of surrounding areas. Recent neurophysiological evidence suggests that brightness information might be explicitly represented in V1, in contrast to the more ...

Top-down input modulates visual context processing through an interneuron-specific circuit
Cell Reports, 2023 Summary: Visual stimuli that deviate from the current context elicit augmented responses in the primary visual cortex (V1). These heightened responses, known as “deviance detection,” require local inhibition in the V1 and top-down input from the anterior

, 2021 The single-cell RNA-sequencing (scRNA-seq) field has evolved tremendously since the first paper was published back in 2009. While the first methods analysed just a handful of cells, the throughput and performance rapidly increased over a very short timespan.

Bio-inspired motion-adaptive estimation algorithm of sequence image
工程科学学报, 2017 To overcome the insufficiencies of varying illumination, large displacement estimation, and outlier removal, a motion-adaptive V1-MT (MAV1MT) motion estimation algorithm based on machine learning and a bio-inspired model of sequence image was proposed ...

A survey of architecture and function of the primary visual cortex (V1) [PDF]
, 2006 The largest visual area, known as the primary visual cortex or V1, has greatly contributed to the current understanding of mammalian and human visual pathways and their role in visual perception.

Simulation of Syngas Production from Lignin Using Guaiacol as a Model Compound
Energies, 2015 Lignin is an abundant component in biomass that can be used a feedstock for producing several value-added products, including biofuels. However, lignin is a complex molecule (involving in its structure three types of phenylpropane units: coumaryl ...

Construction of direction selectivity in V1: from simple to complex cells [PDF]
, 2011 Despite detailed knowledge about the anatomy and physiology of the primary visual cortex (V1), the immense number of feed-forward and recurrent connections onto a given V1 neuron make it difficult to understand how the physiological details relate to a ...

A single mechanism can explain the speed tuning properties of MT and V1 complex neurons [PDF]
, 2006 A recent study by Priebe et al., (2006) has shown that a small proportion (27%) of primate directionally selective, complex V1 neurons are tuned for the speed of image motion.

Primary visual cortex activity along the apparent-motion trace reflects illusory perception [PDF]
, 2005 The illusion of apparent motion can be induced when visual stimuli are successively presented at different locations. It has been shown in previous studies that motion-sensitive regions in extrastriate cortex are relevant for the processing of apparent ...
