Inhibition from these cells is necessary to prevent the untuned component of the LGN input from driving spiking in tuned simple cells at orientations far from the cell's preferred orientation. Hirsch et al. (2000) recently reported two classes of inhibitory cells in cat V1 layer 4: simple cells that appeared to have good orientation tuning and complex cells that were essentially untuned for

How cells determine their position and orientation (defined as a polar or nematic orientation of an intracellular polarity field) in a cell In plants, where cells are immobile, tissue size is achieved through control of both cell division orientation and mitotic rate.

2012-01-17 Controlling the cell orientation is an important technique in single cell surgery. For example, in polar body preimplantation genetic diagnosis (PGD), the cell shall be ori-ented in a way such that polar body can be extracted without any invasive damage to the cell components [14]. Oriented cell division plays a key role in controlling organogenesis. The mechanisms for regulating division orientation at the whole-organ level are only starting to become understood.

Motile single dinoflagellate cells have per definition an orientation. This cell orientation needs to be understood to describe the species properly and to understand published descriptions. The cell is divided in an upper part and a lower part separated by the cingulum (transverse furrow).

Most of the cells in orientation columns are complex cells. Complex cells will respond to a properly orientated line in any location of the receptive field, whereas simple cells have a narrower receptive field where a properly oriented line will excite it. Simple cells have distinct subdivisions of excitatory and inhibitory regions.
AU - Jakobsson, Ola. AU - Antfolk, Maria. AU - Laurell, Thomas 2017-02-28 Abstract. The deposition of nascent cellulose microfibrils (CMFs) was studied in the walls of cortical cells in explants of Nicotiana tabacum L. flower stalks. In freshly cut explants the CMFs were deposited in two distinct and alternating orientations — all given with respect to the longitudinal axis of the cell —, at 75° and 115°, in a left-handed (S-helix) and right-handed (Z-helix The cortical contribution to the orientation and direction sensitivity of LGNd relay cells was investigated by recording the responses of relay cells to drifting sinusoidal gratings of varying spatial frequencies, moving bars, and moving spots in cats in which the visual cortex (areas 17, 18, 19, and LS) was ablated. The core components of the spindle orientation machinery are few and well conserved, differing slightly depending on the cell type and the mode of cell division (Morin and Bellaïche, 2011). For example, in asymmetrically dividing Drosophila melanogaster neuroblasts (NBs), the apical proteins Par-6, Par-3 (Bazooka, Baz, in Drosophila ), and atypical PKC (aPKC) associate with Inscuteable (Insc).
