1. Left LIP (left hemisphere)
Functions linked to language and details: The left hemisphere, in general, is more involved in processing details, language and logical analysis. Therefore, the left LIP may be more related to attention to visual stimuli that require detailed analysis and precise motor planning, such as reading, writing, or coordinated eye movements for activities that involve sequences, such as following words on a page.
Attention directed to stimuli on the right side of the visual field: The left LIP controls the right side of the visual field. This means it becomes more active when you pay attention to objects or events that appear to your right.
2. Right LIP (Right Hemisphere)
Global spatial and visual functions: The right hemisphere is more specialized in global visual attention and spatial perception. The right LIP tends to be more involved in tasks that require an overview of the environment, such as perceiving multiple objects at once or navigating in space. It is also associated with more diffuse attention and visual integration in wider environments, such as monitoring a wider field of view.
Attention directed to both sides of the visual field, with emphasis on the left: The right LIP can control attention to both the left and right visual fields, but is generally more active in controlling the left side. Interestingly, the right LIP has a more dominant function in regulating attention in general, making it crucial in spatial orientation.
In men, the sideleft side of the LIP is larger than the right side. In women, asymmetry is exactly the opposite.
It was carried out thanks to the analysis of image scans MRI scans of 15 men and women. Volumes were calculated. Even after ruling out the natural differences that exist in total brain volume between men and women, there still remained a 5% difference between LIP volumes (the brain of men is, on average, approximately 10% higher than that of women).
In general, LIP allows the brain to process information from the sense organs and help in selective attention and perception. Studies have linked the LIP right to memory involved in understanding and manipulating spatial relationships and ability to establish relationships between parts of the body. It is also related awareness of our own feelings or emotions. The left LIP is implicated in perception of time and space and the ability to mentally rotate three-dimensional figures.

In another research, he presented morphological evidence that, although men have more neurons in thecerebral cortex, women have a more developed neuropil - that is, the space between the bodiescells that contain synapses, dendrites and axons, and allow communication betweenneurons. This research may explain whywomen are more prone to dementia (due to Alzheimer's disease, for example) than men, because although they both lose the same number of neurons due to the disease, "in men, the functional reserve may be greater, as there are a greater number of nerve cells, whichcould avoid part of the functional losses."
