Lateral brain damage can also affect visual perceptual spatial resolution. People with left hemisphere damage may have impaired perception of high resolution, or detailed, aspects of an image. People with right hemisphere damage may have impaired perception of low resolution, or big picture, aspects of an image.
The impact of neurological disorders is profound and far-reaching. Conditions like epilepsy create recurring seizures through abnormal electrical brain activity, while multiple sclerosis damages the protective myelin covering of nerve fibers, interrupting communication between the brain and body.
Alpha waves again gained interest in regards to an engineering approach to the science fiction challenge of psychokinesis, i.e. control of movement of a physical object using energy emanating from a human brain. In 1988, EEG alpha rhythm was used in a brain–computer interface experiment of control of a movement of a physical object, a robot.
Somatosensory mapping involves measuring electrical responses on the surface of the brain as the result of the stimulation of peripheral nerves, such as mechanoreceptors that respond to pressure on the skin, and stimulating the brain directly to map sensory areas. Sensation has been tested in patients through the stimulation of the postcentral ...
The same study revealed differences in the anatomical connection patterns between the left and right hemisphere. [ 4 ] The circular sulcus of insula (or sulcus of Reil [ 5 ] ) is a semicircular sulcus or fissure [ 5 ] that separates the insula from the neighboring gyri of the operculum [ 6 ] in the front, above, and behind.
Consequently, the left side of the forebrain mostly represents the right side of the body, and the right side of the brain primarily represents the left side of the body. The contralateral organization involves both executive and sensory functions (e.g., a left-sided brain lesion may cause a right-sided hemiplegia).

The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
