Orientation preference in the primary visual cortex is a prominent feature of higher mammals. The neurons are arranged in the fix orientation in a primary visual cortex.
The orientation map has analysed that there are pinwheel like orientation are arranged in the ordered fashion. Orientation preference of straight-line stimuli across the primary visual cortex is arranged in pinwheel pattern.
This gives each hydrogen atom two electrons in its outer energy level, which is full. It also gives oxygen 8 electrons in its outer energy level, which is also full.
