Complex cell - Wikipedia
Complex cell - Wikipedia. Complex cells can be found in the primary visual cortex (V1), [1] the secondary visual cortex (V2), and Brodmann area 19 (V3). [2] Like a simple cell, a complex cell will respond primarily to oriented edges and gratings, however it has a …
Where the heck did all those structures inside complex cells come …
Oct 29, 2023 · One cell ended up inside the other and evolved into a structure that schoolkids learn to refer to as the “powerhouse of the cell”: the mitochondrion.
Learning receptive field properties of complex cells in V1
Mar 2, 2021 · Results show that model complex cells can account for the diversity of complex cells found in experimental studies. In summary, this study provides a plausible explanation for how complex cells can be learned using biologically plausible plasticity mechanisms.
What simple and complex cells compute - PMC - National Center …
Dec 1, 2006 · The models of simple and complex cells proposed by Movshon, Thompson and Tolhurst (Movshon et al. 1978a,b) A, linear model of simple cells. The first stage is linear filtering, i. e. aweighted sum of the image intensities, with weights given by the receptive field.
Golgi apparatus | Definition, Function, Location, & Facts
Oct 29, 2024 · The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae.
A complex cell - Nature Immunology
Dec 17, 2015 · Nature Immunology - New data redefine macrophages as diverse, polyfunctional and plastic cells that respond to the needs of the tissue at steady state and during disturbed homeostasis.
Learning receptive field properties of complex cells in V1
There are two distinct classes of cells in the primary visual cortex (V1): simple cells and complex cells. One defining feature of complex cells is their spatial phase invariance; they respond strongly to oriented grating stimuli with a preferred orientation but with a wide range of spatial phases.

Complex cellular structures | Annals of Mathematics
We introduce the notion of a complex cell, a complexification of the cells/cylinders used in real tame geometry. For $\delta \in (0,1)$ and a complex cell $\mathcal{C}$, we define its holomorphic extension $\mathcal{C}\subset \mathcal{C}^\delta $, which is again a complex cell.
