cerebral cortex
answer
The outermost layer of the cerebrum. Folded to allow for 1.5 square feet to fit into the skull. Is the body's control center and information processing center.
question
corpus callosum
answer
A thick band of axon fibers that connects the cerebral hemispheres. responsible for communication between hemispheres. Contains over 200 million axons.
question
occipital lobe
answer
The portion of the cerebral cortex located at the back of the head that includes areas responsible for visual processing.
question
parietal lobe
answer
The portion of the cerebral cortex located in front of the occipital lobe that includes areas responsible for registering sensations and monitoring body position. Also integration of visual input and contains the primary somatosensory cortex
question
temporal lobe
answer
The portion of the cerebral cortex located below the parietal lobe that includes areas responsible for auditory processing.
question
frontal lobe
answer
The portion of the cerebral cortex located behind the forehead that includes areas responsible for speaking, muscle movement, and making decisions and judgments. It is the largest lobe in the brain, and contains the primary motor cortex, mirror neurons, and prefrontal cortex.
question
mirror neurons
answer
Neurons that are triggered upon performing or observing another perform an action. Found by chance during experiments with monkeys. circuits found in frontal and pariental lobe. associated with the development of motor and social skills (feeling empathy, developing language)
question
cerebrum
answer
the largest part of the forebrain. responsible for the integration of sensory and neural functions.
question
three areas of cerebrum
answer
cerebral cortex, cerebral hemispheres, and corpus callosum
question
cerebral hemispheres
answer
divided into two halves, separated by longitudinal fissure, left side controls the right side of the body and vice versa.
question
cut corpus callosum
answer
to stop seizures, help researchers understand communications
question
four lobes
answer
located on each hemisphere and are separated by prominent fissures. each hemisphere has four identical lobes
question
primary visual cortex
answer
Visual processing begins in the primary visual cortex, which is located at the very back of the occipital lobe
question
somatosensory cortex
answer
it is located in the front area of the parietal lobe and receives signals for various areas of the body registering sensory input. The tissue area of sensory cortex is larger for more sensitive parts of the body.
question
primary auditory cortex
answer
it is located at the top of the temporal lobe and receives auditory information from the ears
question
primary motor cortex
answer
located at the top of the head in front of the somatosensory cortex, controls movement of muscles, amount of tissue depends on complexity and amount of control it takes to move that body part
question
prefrontal cortex
answer
in front of the primary motor cortex, takes up one third of cerebral cortex, function not clear: processing information in memory, reasoning about object or event relationship, decision making, directing thought processes
question
Each hemisphere of the brain specializes in assisting various functions of the body.
answer
T
question
The primary __________ cortex specializes in receiving signals from different parts of the body.
answer
somatosensory
question
At the corpus callosum, __________ occurs between the two hemispheres.
answer
. communication
question
Located in the back of the head, the __________ lobe is where most visual signals are sent.
answer
occipital
question
The parietal lobe is the portion of the cerebral cortex located below the temporal lobe.
answer
F
question
The areas for speech are found in the _________ and __________ lobes.
answer
temporal . . . frontal
question
Integration of visual input and monitoring the body's orientation in space are functions of the __________ lobe.
answer
parietal
question
The __________ lobe contains the area of the cortex involved in auditory processing called the primary __________ cortex.
answer
temporal . . . auditory
question
Neurons activated when an individual performs an action or sees another performing the action are __________ neurons.
answer
mirror
question
The primary __________ cortex contains a map of the body based on the importance of sensory input from different parts of the body.
answer
NOT motor
question
The cerebral cortex is divided into two halves called cerebral hemispheres.
answer
F
question
The somatosensory cortex is in the __________ lobe.
answer
parietal
question
The parietal lobe is the portion of the cerebral cortex located below the temporal lobe.
answer
F
