Lobes of the Brain

Involved with cognitive processes such as judging, planning and initiative, aspects of personality and emotions and voluntary muscle movements.

• Primary motor cortex
• Involved in controlling voluntary body movement through its control of muscles

• Broca's area, found in the left frontal lobe
• Production of clear, articulate speech
• Vital for the proper grammatical structure of sentences
• Coordinates the movements of the muscles required for speech

• Wernicke's area
• Vital role in interpreting sound and speech comprehension. Locating and retrieves words from memory.

• A. Broca's area
• B. Primary motor cortex
• C. Primary somatic sensory Cortex
• D. Somatic sensory association area (parietal lobe)
• E. Wernicke's Area
• F. Primary visual cortex

Frontal lobe: complexity of movement

• Perception of own body and where things are located in immediate surroundings
• Right: perception of three-dimensional shapes and designs. Awareness of space and location of objects in environment
• left: mental arithmetic, reading and writing

Responsible for processing bodily sensations such as pain, temperature, touch & pressure

• Responsible for processing auditory information. Remembering faces, memory
• Primary auditory cortex: analyses sensations perceived through the ears eg. speech, music

• Concerned with vision. Organises visual stimuli into more complex forms to enable interpretation
• Primary visual cortex: Processes different types of visual stimuli

Language difficulties such as writing, reading and speaking due to damage to the brain

• aka Receptive aphasia
• The individual has trouble understanding written and spoken language.
• Speech is fluent but meaningless
• Partial or complete loss of ability to recall names (anomia)

• Caused by damage to Broca's area
• aka Expressive aphasia
• Difficulties speaking, non fluent
• Speech lacks grammar and syntax
• Difficulty with writing
• Partial or complete loss of ability to recall names (anomia)
• Can usually comprehend speech

• A disorder in which an individual ignores stimuli on one side of their body
• Occurs after brain injury (caused by stroke or brain injury) and relates to visual stimuli.
• ‘blind’; the eyes function normally however
• the brain is unable to process visual stimuli normally.
