What are complex cells?

Visual cortex, located towards the back of the brain, has many specialized cells that contribute to the perception of visual stimuli. Some of these specialized neurons are known as complex cells. These cells are found in the three areas of the largest part of the brain called the brain. These three areas are known as the primary and secondary visual cortice and another nearby area called Brodmann Area 19, all of which are located towards the back of the brain. It seems that complex cells

play an important role in the recognition of objects, especially when they are located in the Brodmann 19 area. This area seems to be a point where visual signals branch into "what" and "where". The first path determines what objects they look at, and the second determines where they are located in space. These specialized cells seem to help the brain to decide what the object is, by providing information about the lines that compose it.

in the visual system, Complex cells are connected to the border recognition andof the edges. Specific cells will respond to the specific orientation of the lines. The related cell type, known as simple cells, will also respond in this way. They will respond to the orientation of the line anywhere in their large receptive field, regardless of their exact location. With regard to the need to activate specific orientations, some of these cells fire when they detect directional movement.

To determine the orientation on the line, the contrast between the areas of light and darkness is required, as can be seen through the visual cells of the eye. The rods and cones broadcast information about the border between light and darkness on simple cells that interpret them as edges. Simple cells then say complex cells of small parts of these edges and a complex sum of cells together create a greater concept of edges or contours of shapes.

The way in which the visual system is set first includes several simple cells that receive inIZUAL ENTRY. The lines in a certain orientation and occurring in a precise place in the receptive field of the cell will cause to fire. The receptive fields are the exact area in which visual cells detect stimuli. For example, simple cells respond only to the edges detected within their specific field. Stimuli outside the receptive field will lead to inhibition close to cells.

After activation of the given orientation, simple cells transmit this information to a smaller number of complex cells through converging inputs. These cells integrate the information they receive and send it to other visual areas for further processing. Other processes, such as visual memory and shape recognition, may require input from these cells depending on the area they are located.
