The Roles Of Our Lobes

1) Occipital Lobes

• The primary function of occipital lobes is to process visual stimuli. When stimuli reach the visual cortex, they are processed in the primary visual perception area
• Two people can look at the same thing and focus on something different or they can see different things.

2) Parietal Lobes

• At the top of the brain is a flat, plate-like area in each hemisphere called the parietal lobes.
• The Lobes are composed of two major subdivisions:

-The anterior

-The posterior

⦁ The anterior (front) is behind the motor cortex and lies a strip of cells called the somatosensory cortex.

The somatosensory cortex is an important part of receiving information such as touch and temperature from our environment and pain sensations. 

If a part of the body becomes sensitive, the area needs to interpret its messages. 

For example, our lips, tongue, and throat have the largest receptors. Damage to the part of a parietal lobe intervenes with the perception of touch and pain with the knowledge of the body’s position in space.

⦁ The posterior (rear) part of the parietal lobes analyzes and integrates all this information to give you a sense of spatial awareness.

⦁ The final role is that parietal lobes maintain focus or spatial attention. If someone wears tight and painful shoes, the focus will be kept on the feet. When taking off the shoes, the receptors stop sending information.

3) Temporal Lobes

• The main function of temporal lobes is to process auditory stimuli.
• When the auditory area of the temporal lobes is stimulated, sensations of sound are produced.
• Wernicke’s Area (Left occipital, parietal, and temporal lobes) is vital for speech and allows us to comprehend or interpret speech. 

4) Frontal Lobes

The frontal lobes are the largest part of the cortex and perform the most complicated functions. 

• Some actions like moving parts of the body, thinking about the past, planning for the future, making decisions, and solving problems are possible with this developed area of the brain.
• Toward the back of the frontal lobes is a strip of cells that stretches across the top of the brain. The strip is known as the motor cortex.
