Cns And Pns

Occurs due to damage to Broca's Area (frontal lobe). Impaired speech production. Nouns and verbs are predominately used, sometimes cues are required. Frustration evident.

Occurs due to damage to Wernicke's area (temporal lobe). Impaired speech comprehension. Fluent speech yet it is nonsense. No knowledge evident of disorder.

Occurs due to damage to parietal lobe. Half of the victims world is ignored. Usually sight yet sometimes other sense or a combination of senses are involved. Attentional disorder. They will see neglected half when attention is brought to it. E.g half of a picture is drawn, not notice someone approaching their left side.

Involved in higher order mental functions. Involved in attention, problem solving planning, concept of time, meaning of concepts, personality, control and expression of emotions. Determines behavioral responses.

Controls voluntary body movements. The left primary motor cortex controls the right side of the body and vise versa.

Responsible for production of articulate speech. It coordinates the muscles of the mouth and throat. Involved in correct grammatical structure.

Involved in attention, spatial perception and reasoning. Bodily awareness based on sensations of touch, pressure, heat, pain and movement.

Receives and processes sensory information from the skin and body. Enable use to perceive touch, pressure, pain, heat and movement.

Primarily involved in hearing. Also involved in object and facial recognition, memory, linking emotions to memory. Determining features of our environment that we perceive and remember. Appropriate emotional responses based on memory of senses.

Receive and process different feature of sound including frequency (pitch) and amplitude (loudness). Verbal sounds in left (words), non verbal in right (music).

Primarily involved in vision. Interacts with other lobes frequently as information about vision is sent to other lobes.

Processing and receiving visual information. Specialized to respond to different features of visual information, such as orientation of a line, edges, shape, motion and colour. Select, organize and integrate visual info.

The idea that one hemisphere exerts greater control over particular functions. Although both are involved in most mental processes.

Breaks info into smaller details. Logical reasoning and problem solving. Verbal. Language production and comprehension. Analytical.

Artistic endeavors, emotional reasoning, music and art appreciation. Sees information as a whole. Spatial and visual thinking, creation of new ideas.

The left hemisphere is responsible for language production and comprehension, and the right is responsible for object identification. The hemispheres exchange information. Hemispheres independently control body parts in the right or left.

Justice: Why the chosen participant over others
Beneficence: Risk vs benefit

Respect for Persons: Rights and dignity protected

Integrity: genuine intent of contribution to scientific community.

Carry's info to and from the CNS to the body.

Transmission of sensory info from the body's receptors to the CNS. (Afferent)

Transference of motor messages from the CNS to the skeletal muscles. (Efferent)

Connects the CNS to internal muscles, organs and glands involved in non voluntary functions. Provides feedback to the brain.

Increases activity of most visceral muscles, organs and glands, in response to stress, threat or vigorous activity. Provides immediate survival response. (flight or fight)

Decrease activity of visceral muscles, organs and glands to return the body to homeostasis.
