SPECT only provides information about brain function, whereas PET only provides information about brain structure.
SPECT only provides information about brain structure, whereas PET only provides information about brain function.
SPECT provides three-dimensional brain images, whereas a PET only provides two-dimensional images.
SPECT uses a longer-lasting radioactive tracer than does PET.

The left and right hemispheres control voluntary movements on both sides of the body and receive sensory information from both sides of the body.
The left and right hemispheres exchange and process sensory information before deciding which side of the body requires control of voluntary movements.
The right hemisphere controls voluntary movements on the right side of the body and receives sensory information from the right side of the body.
The left hemisphere controls voluntary movements on the right side of the body and receives sensory information from the right side of the body.
Receives and filters information from the cerebral cortex and transmits it to lower brain structures.
Receives and filters information from all the major senses and transmits it to the cerebral cortex.
Connects the left and right cerebral hemispheres.
Coordinates the activities of brain areas involved in speech production and comprehension.
Connect the brain and peripheral nervous system.
Protect the vertebrae.
Enable sensory neurons to connect directly with motor neurons.
Initiate voluntary muscle movements.
Motor neurons send messages to the sensory receptor cells, whereas sensory neurons send messages from the sensory receptor cells.
Motor neurons send messages to muscles and glands in the peripheral nervous system, whereas sensory neurons send messages from the somatosensory cortex.
Motor neurons carry information away from the central nervous system, whereas sensory neurons carry information to the central nervous system.
Motor neurons connect to interneurons, whereas sensory neurons do not.

Voluntary movements of skeletal muscles.
Involuntary movements of skeletal muscles.
The amount of cortex that is sensitive to movement.
The sensitivity of body parts.
‘hearing’ faint sounds
‘seeing’ random visual patterns
Movement of one or more of the larger body parts
A sense of having the skin touched

Degree of stimulation of the body parts.
Degree of precise control required by each of the parts.
Sensitivity of the sensory receptors controlling the body parts.
Sensitivity of the body parts.
Reading a novel
Following the directions in a recipe
Finding one’s way around a maze
Logical reasoning
Change is expected.
There is a visual disruption.
Change is unexpected.
There is a conscious sense that change is occurring.

Spatial neglect is a disorder involving attention.
Spatial neglect has many types of subtypes.
Spatial neglect usually involves neglect of the right side.
Spatial neglect is most commonly associated with damage to the right parietal lobe.

Individuals are always aware of what is going on in their environment.
Memory is not involved in conscious awareness.
Change can be detected without having a conscious experience of the change.
Prolonged exposure to a visual stimulus can result in ‘fatigue’ by neurons detecting upward direction.
