The neurons of area are important for the analysis of color.

The neurons of area V4 are important for the analysis of color. The area characterized as the color area is Area v4. This is said to be the where the color is further processed. Because of the strength of the color receptive field in its neurons, this is the reason why v4 is an area of interest.  Initially, Zeki introduced v4 to be solely involved in processing of color but then this was proved to be incorrect. Later, it was found out that v4 is responsible for processing both color and at the same time form associated with color.  In the extended v4 occur in color modules called globs. 

What we cannot learn from the fossils found in rock strata is: the diversity of organisms at a certain location or during a certain time period.

Rock strata (layers) that are found in various parts of the world are usually different from one another because they all comprises distinct Earth's geological history, which are referred to as fossils.

A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are prehistoric in nature.

This ultimately implies that, fossils are ancient organisms such as plants and animals that were formed into rocks.

Some of the information that can be learnt from the fossils found in rock strata are:
