2.06 Flashcards
Cerebral cortex or cortex
Thin outer layer of the cerebral hemisphere; acts as main control center and information processing center; not required for performing many simple actions, but crucial for creating new episodic memories and many new movement programs; made up of motor cortex and sensory cortex.
Other hand on top of the fist – one in charge of it all – this is the command center – sensory and motor
Cerebral hemispheres
The two sections of the cortex on the left and right sides of the brain.
One whole fist (which is just half)
Corpus callosum
Thick bank of neurons that connects the right and left cerebral hemispheres.
Middle finger that connects the two halves of the brain.
Occipital lobe
Section of the brain located at the rear and bottom of each cerebral hemisphere containing the primary visual centers of the brain.
Make a fist as the brain – back of hand towards you, knuckles away. This is the back of the hand (back of head). Wear your glasses backwards on your head for your brain when it is sunny.
Visual cortex
The largest area in the occipital lobe where visual information is sent; visual images, relayed from the eye are projected onto the visual cortex and each hemisphere divides the information - the right hemisphere is responsible for the left visual field, the left hemisphere is responsible for the right visual field.
Projector screen of the occipital lobe
Parietal lobes
Sections of the brain located at the top and back of each cerebral hemisphere containing the centers for touch, temperature, and body position.
Knuckles on top back of your hand (head) and upper part of fingers. Knuckles are T (touch), T (temp) B P (body position)
Somatosensory cortex
Area of cortex at the front of the parietal lobes responsible for processing information from the skin and internal body receptors for touch, temperature, and body position.
Upper part of fingers in back near main knuckles - Processing area of the Parietal lobe for TTBP
Temporal lobes
Areas of the cortex located along the side of the brain, starting just behind the temples,k containing the neurons responsible for the sense of hearing and meaningful speech.
Open circles on the side of the fist – just like the open soft spots on the side of the head for this area of the brain – near the ears – does Hearing and speech
Auditory cortex
Located in the temporal lobe and solely responsible for hearing.
Cortex used for hearing in temporal lobes
Frontal lobes
Areas of the brain located in the front and top, responsible for higher mental processes and decision making as well as the production of fluent speech.
Lower two parts of Fingers of the fist. Thinking part of brain and speech
Motor cortex
Rear section of the frontal lobe, responsible for sending motor commands to the muscles of the somatic nervous system.
Upper part of fingers – near middle knuckle. Commands muscles of SNS. In front of somatosensory cortex
Mirror Neurons
Neurons that fire when an animal or person performs an action and also when an animal or person observes that same action being performed by another.
Neurons that fire when a person watches an action they have done before.
Association areas
Areas within each lobe of the cortex responsible for the coordination and interpretation of information, as well as higher mental processing.
Helps link areas of the brain together to work together for higher thinking
Broca’s Area
An area located in the left frontal lobe that is responsible for controlling the muscles in the mouth involved in speech.
Area on Left finger of the fist. Muscles for speech
Broca’s aphasia
Condition resulting from damage to Broca’s area, causing the affected person to be unable to speak fluently, to mispronounce words, and to speak haltingly.
Results from injury causing disruptive speech
