In primates, single-neuron correlates of category selectivity have been found in many cortical regions. In areas such as prefrontal cortex, lateral intraparietal cortex, posterior inferotemporal cortex and the frontal eye fields, substantial populations of category-selective neurons were observed following...
In the primary visual cortex (V1), simple cells each have a receptive field (RF) structure that is modeled by a two-dimensional (2D) Gabor function11. Theoretically, a single natural scene is represented by a relatively small number of neurons using Gabor-like RFs, whereas information about...
Visual cortex Neural correlate Synchrony Contextual modulation Neuropsychology 1. Introduction In the non-dualistic approach to consciousness, visual awareness is mediated by the activity of nerve cells. The question that is specifically addressed in this paper, is to what extent the nerve cells in vis...
According to some neurologists, the primary function of the visual cortex is to construct consistencies in the visual field, with the aim of obtaining useful knowledge about the world. Responding to ‘the brain's incessant demand for constancy’ (Zeki 1997, p. 86), visual artists search for ...
Insular Cortex Intracellular Recording Neurological models Introduction The cellular composition of the brain is diverse, with recent studies in rodent neocortex identifying tens of cell types1,2,3,4. The expectation is that these types serve distinct roles in behavior. However, disentangling their fun...
We measured population responses in cat primary visual cortex (V1) using electrode arrays. Popula... L Busse,AR Wade,M Carandini - 《Neuron》 被引量: 290发表: 2009年 Decoding the activity of neuronal populations in macaque primary visual cortex. Visual function depends on the accuracy of ...
increased dendritic spine densities and decreased spine size [11]. Consistent with the latter, here we show that nectin-3 may function to limit dendritic spine densities following eye opening in L2/3 visual cortex. These observations collectively indicate that nectin-3 may have a role in synapse...
Having SD card support in the image also allows other built-in Android apps to function, such as the browser downloads and the camera app – which brings me to the next capability. Camera Typically you’d be using the camera from your app (using an appropriate API), and we support that...
orthogonal direction of the prefered orientation. If one wants to recover the ring model of orientation tuning in the visual cortex as it has been presented and studied by [1,2,19], it is sufficient i) to assume that the connectivity function is time-independent and has a convolutional form...
Here, we leverage population receptive field models to parameterize fMRI activity in human visual cortex during spatial memory retrieval. Though retinotopic organization is present during both perception and memory, large systematic differences in tuning are also evident. Whereas there is a three-fold ...
