The parietal lobe sits posterior to the frontal lobe and anterior to the occipital lobe and medial to the two temporal lobes. It is located on the upper back portion of the skull. The central sulcus separates the frontal lobe and the parietal lobe while lateral sulcus separates the parietal lobe from the temporal lobe (Drake et al., 2015 ) . The parieto-occipital sulcus separates the parietal lobe from the occipital lobe.
The parietal lobe receives sensory information from different parts of the body for example the hands, the legs, the skin among others after which it interprets this information thus triggering the appropriate response. It is for this reason it is referred to as the primary sensory area of the brain (Drake et al., 2015 ). Some of the sensory information that is processed by the parietal lobe include touch, heat, cold, pain, pressure and tension. All these are referred to as somatic senses as they originate from different parts of the body. Interpretation of this sensory information helps the individual to make sense of the environment around them. Other functions that are controlled by the parietal lobe include hearing, memory and visual perception and language.

Damage to the parietal lobe produces various syndromes depending on the part of the parietal lobe that is damaged. Left parietal-temporal lesions produce verbal memory loss and also affects the ability of an individual to remember strings of numbers. Damage to the right parietal lobe results in contralateral neglect of part of the body which affects the ability of an individual to take care of themselves in terms of dressing and washing (Drake et al., 2015 ). Right sided damage can also affect the ability of an individual to make things and even drawing. Damage to the left parietal lobe can cause right-left confusion, cause difficulties in writing as well as produce disorders of language as well as the ability to recognize objects.
