Receives and coordinates messages from the other lobes in the brain
Contains the primary motor cortex and Broca's area
Responsible for higher mental functioning such as:
Logical thinking
Reasoning
Planning

Primary Motor Cortex (part of the frontal lobe)
Responsible for the planning, initiating and performing of voluntary movement
Controls voluntary bodily movements ia the control of the skeletal muscles
This cortex is in each hemisphere of the brain, left and right, and controls movements from the opposite side of the body (the cortex in the left hemisphere controls the right side of the body)
Different areas of the cortex control different parts of the body
Body parts with more 'precise' movement take up more space in the cortex
2 of 10
Broca's Area (part of the frontal lobe)
Generally found in the left hemisphere of the brain only
Plays a cruicial role in the production of speech that is clear and fluent
Involved with coordinating movements of the muscles that are needed for speech
If damage is done to the area it causes Broca's aphasia (otherwise known as non-fluent aphasia)
Broca's aphasia is the inability to produce or understand clear speech #
Causes speech to be slow and deliberate (but it still makes sense)
People who have Broca's aphasia leave out small words like 'if' and 'but' while speaking

Parietal Lobe
Is found at the top of the hear
Contains the primary somatosensory cortex
Registers sensory information such as:
Touch
Pressure
Pain
Temperature
Bodily movements
4 of 10
Primary Somatosensory Cortex (part of the parietal
Recieves and processes sensory information form specific parts of the body such as the:
Arms
Legs
Hands
Feet
Legs
Lips
Tongue etc
5 of 10
Occipital Lobe
Found at the back of the head
Processes visual information
Contains the primary visual cortex
6 of 10
Primary Visual Cortex (part of the occipital lobe)
Involved in receiving and processing visual information from sensory receptors in the retina (at the back of the eye)
Decides where to the visual information is first transmitted to
7 of 10
Temporal Lobe
Found at the side of the brain, above the ears and behind the temples
In charge of auditory perception, language comprehension, some emotional control and memory (facial recognition)
Contains Wernicke's area
8 of 10
Wernicke's Area (part of the temporal lobe)
Enables the comprehension of speech and language
Also enables the interpretation of written words
Locates words from memory to express a particular meaning
Creates meaningful and gramatically correct speech
Damage to this area results in Wernicke's aphasia (otherwise known as fluent aphasia)
Wernicke's aphasia affects your ability to comprehend speech
People with Wernicke's aphasia can't produce meaningful sentences but can string words together
9 of 10
Primary Auditory Cortex (part of the temporal lobe
Receives and processes sound from both ears so we can perceive and identify different types of sound
Different areas of the cortex register and respond to different types of sound
