The difference between simple and complex cells

[Ninjakannon]

Are complex cells in the brain physically different from simple cells or is the difference in their function/role?

They are essentially the same in their intrinsic properties, the main difference is in the synaptic inputs they receive from other neurons. http://www.ncbi.nlm.nih.gov/pubmed/15338009 , http://www.ncbi.nlm.nih.gov/pubmed/15711543 .

All cells in the same body contain the same genetic information. Different cell types in the body "get that way" by altering the expression of genes. Liver cells (hepatocytes) have different genes "turned on" than say brain cells (neurons, glial cells etc).

All cells have certain functions always running, like sodium-potassium pumps. The other protein machinery and enzymes active in the cell are dependent upon the cells lineage and cells 'job'.

Thanks guys; atyy, that was exactly what I needed.

The difference between simple and complex cells lies in their structure and function. Simple cells, also known as single-celled organisms, are made up of a single cell and perform all necessary functions within that cell. They are typically smaller and have a simpler structure compared to complex cells.

On the other hand, complex cells, such as those found in the human brain, are made up of multiple cells and have a more intricate structure. These cells work together to perform specific functions and make up the various tissues and organs in the body. They are specialized and have specific roles in maintaining the body's functions.

In terms of physical differences, complex cells in the brain are indeed different from simple cells. The brain is made up of various types of complex cells, such as neurons and glial cells, each with its own unique structure and function. These cells have specialized structures, such as dendrites and axons, that allow them to communicate with each other and form complex networks.

The difference between simple and complex cells is not just limited to their physical structure, but also their function and role. While simple cells perform all necessary functions within a single cell, complex cells work together to carry out more complex tasks and maintain the body's overall function.

In conclusion, the difference between simple and complex cells lies in their structure, function, and role. Complex cells in the brain are physically different from simple cells, as they have a more specialized and complex structure, allowing them to carry out more complex functions.
