The LGN receives information directly from the ascending retinal ganglion cells via the optic tract and from the reticular activating system. Neurons of the LGN send their axons through the optic radiation, a direct pathway to the primary visual cortex. In addition, the LGN receives many strong feedback connections from the primary visual ...
Koniocellular neurons not labeled, but are present between the layers. In neuroscience , koniocellular cells , also called K-cells , are relatively small neurons located in the koniocellular layer of the lateral geniculate nucleus (LGN) within the thalamus of primates , including humans.
In neuroscience, parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus. Their name comes from Latin parvus 'small', due to the small size of the cell compared to the larger magnocellular cells. Phylogenetically, parvocellular neurons are more modern ...
An additional set of neurons, known as the koniocellular cell (K cell) layers, are found ventral to each of the M cell and P cell layers. [2] [3]: 227ff [4] These layers were named this way because cells in the M layers of the LGN are larger than cells in the P layers. [3]: 228 [5]
Receptors are located throughout the body including the skin, epithelia, internal organs, skeletal muscles, bones, and joints. The cutaneous receptors of the skin project in an orderly fashion to the spinal cord , and from there, via different afferent pathways ( dorsal column-medial lemniscus tract and spinothalamic tract ), to the ventral ...
These neurons show roughly circular receptive fields with antagonistic center and surround; this property is known as spatial opponency and these neurons are typically divided into ON- or OFF-center, depending on whether they are excited or inhibited by photons falling on the center of their receptive fields.

Angelina Jolie balked at a question regarding whether there should be a biopic about her life.. When Jolie, 49, and her Maria director Pablo Larraín spoke with the U.K.'s The Times to promote ...
A parasol cell, sometimes called an M cell [1] or M ganglion cell, [2] is one type of retinal ganglion cell (RGC) located in the ganglion cell layer of the retina.These cells project to magnocellular cells in the lateral geniculate nucleus (LGN) as part of the magnocellular pathway in the visual system.
