Towards building a more complex view of the lateral geniculate nucleus: Recent advances in understanding its role

M Ghodrati, SM Khaligh-Razavi, SR Lehky - Progress in Neurobiology, 2017 - Elsevier
The lateral geniculate nucleus (LGN) has often been treated in the past as a linear filter that
adds little to retinal processing of visual inputs. Here we review anatomical …

Emergence of orientation selectivity in the mammalian visual pathway

B Scholl, AYY Tan, J Corey, NJ Priebe - Journal of Neuroscience, 2013 - Soc Neuroscience
Orientation selectivity is a property of mammalian primary visual cortex (V1) neurons, yet its
emergence along the visual pathway varies across species. In carnivores and primates …

Origins of feature selectivities and maps in the mammalian primary visual cortex

TR Vidyasagar, UT Eysel - Trends in neurosciences, 2015 - cell.com
A common feature of the mammalian striate cortex is the arrangement of 'orientation
domains' containing neurons preferring similar stimulus orientations. They are arranged as …

An integrated neuronal model of claustral function in timing the synchrony between cortical areas

TR Vidyasagar, E Levichkina - Frontiers in neural circuits, 2019 - frontiersin.org
It has been suggested that the function of the claustrum (CL) may be to orchestrate and
integrate the activity of the different cortical areas that are involved in a particular function by …

A computational study of how orientation bias in the lateral geniculate nucleus can give rise to orientation selectivity in primary visual cortex

L Kuhlmann, TR Vidyasagar - Frontiers in systems neuroscience, 2011 - frontiersin.org

[HTML][HTML] Effects of stimulus spatial frequency, size, and luminance contrast on orientation tuning of neurons in the dorsal lateral geniculate nucleus of cat

T Naito, M Okamoto, O Sadakane, S Shimegi… - Neuroscience …, 2013 - Elsevier
It is generally thought that orientation selectivity first appears in the primary visual cortex
(V1), whereas neurons in the lateral geniculate nucleus (LGN), an input source for V1, are …

[HTML][HTML] Attentional modulation interacts with orientation anisotropies in contrast perception

IM Bloem, S Ling - Journal of Vision, 2017 - iovs.arvojournals.org

and the means by which it develops without supervision or visual input, both remain …

Receptive field properties of cat perigeniculate neurons correlate with excitatory and inhibitory connectivity to LGN relay neurons

H Osaki, T Naito, S Soma, H Sato - Neuroscience Research, 2018 - Elsevier
The cat perigeniculate nucleus (PGN) is a visual sector of the thalamic reticular nucleus that
