<P> The different senses were always thought to be controlled by separate lobes of the brain, called projection areas . The lobes of the brain are the classifications that divide the brain both anatomically and functionally . These lobes are the Frontal lobe, responsible for conscious thought, Parietal lobe, responsible for visuospatial processing, the Occipital lobe, responsible for the sense of sight, and the temporal lobe, responsible for the senses of smell and sound . From the earliest times of neurology, it has been thought that these lobes are solely responsible for their one sensory modality input . However, newer research has shown that that may not entirely be the case . </P> <P> Sometimes there can be a problem with the encoding of the sensory information . This disorder is known as Sensory processing disorder (SPD). This disorder can be further classified into three main types . </P> <Ul> <Li> Sensory modulation disorder, in which patients seek sensory stimulation due to an over or under response to sensory stimuli . </Li> <Li> Sensory based motor disorder . Patients have incorrect processing of motor information that leads to poor motor skills . </Li> <Li> Sensory processing disorder or sensory discrimination disorder, which is characterized by postural control problems, lack of attentiveness, and disorganization . </Li> </Ul> <Li> Sensory modulation disorder, in which patients seek sensory stimulation due to an over or under response to sensory stimuli . </Li>
