Terms in this set (43)
outer layer of the cerebral hemispheres consisting mostly of large neurons and their branches
ridged portion of convoluted brain surface
furrow in convoluted brain surface
most anterior portion of cerebral cortex. movement and high level cognition.
behind frontal lobe on the dorsal side of the brain. sensory info from body and spatial cognition.
division between frontal and parietal lobes
large lateral cortical regions of each cerebral hemisphere, continuous with parietal lobes posteriorly. auditory processing, learning, memory, sense of smell.
deep sulcus separating frontal and temporal lobes
large regions of cortex covering much of the posterior part of each cerebral hemisphere. vision.
strip of parietal cortex behind central sulcus that receives somatosensory information from the body (sense of touch)
strip of frontal cortex in front of central sulcus that is crucial for motor control
the main band of axons that connects the two cerebral hemispheres
a shiny layer underneath the cortex that consists largely of axons with white myelin sheaths
areas of the brain that are dominated by cell bodies and largely myelin-free
an embryonic structure with subdivisions that correspond to the future forebrain, midbrain, and hindbrain
aka prosencephalon. anterior division of the brain containing the telencephalon, diencephalon, thalamus, and hypothalamus.
midbrain, pons, and medulla
aka mesencephalon. middle division of the brain. contains superior and inferior colliculi
paired gray matter structures of the dorsal midbrain that receive visual information and are involved in direction of visual gaze and visual attention to intended stimuli
paired gray matter structures of the dorsal midbrain that receive auditory information
the dorsal section of the midbrain consisting of the superior and inferior colliculi
aka rhombencephalon. rear division of the brain containing the cerebellum and the metencephalon (pons and medulla).
pons and medulla
structure with elaborate surface convolutions located at the back of the brain, dorsal to the pons, that is involved in the central regulation of movement
axons from granule cells that make up the cerebellum's outer layer
type of large nerve cell in the middle layer of the cerebellum
small nerve cell in the third and deepest layer of the cerebellum whose axons extend to the surface to form parallel fibers
portion of the mesencephalon; part of the brainstem connecting midbrain to medulla
part of brainstem related to motor control
structure stretching from thalamus in the midbrain to the medulla in the brainstem. arousal (waking).
aka the medulla. posterior part of the hindbrain, continuous with the spinal cord.
a loosely defined, widespread group of brain nuclei that innervate each other to form a network critical for emotion and learning
grou pof nuclei in the medial anterior part of the temporal lobe. emotional regulation, fear, and odor perception.
medial temporal lobe structure important for learning and memory.
fiber tract that extends from the hippocampus to the mammillary body. learning and memory.
strip of cortex in each hemisphere found in frontal and parietal midline; implicated in many cognitive functions including attention.
anterior projection of the brain that terminates in the upper nasal passages and, through small openings in the skull, provides receptors for smell
three protective sheets of tissue around the brain and spinal cord - dura mater, arachnoid, and pia mater
fluid that fills the cerebral ventricles, acting as a shock absorber and a medium through which materials can be exchanged between blood and brain tissue
each side of the brain contains a lateral ventricle that extends into all four hemispheres of the brain
membrane lining lateral ventricles that produces CSF by filtering blood
midline ventricle that conducts CSF from the lateral ventricle to the fourth ventricle
passageway within the pons that receives CSF from the third ventricle and releases it to surround the brain and spinal cord. CSF is then absorbed back into the circulatory system through large veins beneath the top of the skull.
