|
longitudinal fissure
|
separates the two hemispheres of the cerebral cortex.
|
|
|
Sulci
|
Where the brain folds in on itself, creating grooves
|
|
|
Irregular shaped spaces between sulci
|
gyri
|
|
|
Gray Matter
|
Cell bodies that cover the cerebral hemispheres
|
|
|
White matter
|
myelinated axons underlying the gray matter
|
|
|
lateral fissure
|
separates the frontal and parietal lobes from the temporal
|
|
|
central sulcus
|
separates the frontal and pareital lobes
|
|
|
parietal-occipital fissure
|
separates the parietal and occiptial lobes.
|
|
|
Somatosensory Cortex
|
Responsible for recieving tactile sensations from the body
|
|
|
Motor cortext
|
the posterior aspect of the frontal lobe associated with initiating, activating, performing motor activity.
|
|
|
Association Areas
|
integration of somatosensory, motor, and visual input into a highly integrated area.
|
|
|
Prefrontal Cortex (frontal lobe)
|
organizing, controlling, managing behavior, making high level decisions about socially appropriate behavior
|
|
|
Dorsolateral (in the prefrontal cortex)
|
higher-order, executive functions.
|
|
|
Orbital (in the prefrontal cortex)
|
modulation of emotional-social behavior
|
|
|
Anterior Cingulate (in the prefrontal cortex)
|
motivational behavior
|
|
|
Hemispheric Asymmetry
|
Differnces between the right and left hemispehere.
|
|
|
Laterialization/ Dominance
|
Refers to the differnces in functional specialization between the two hemispheres
|
|
|
Left hemisphere
|
suited for single-modality, intraregional processing, more suited for processing info that is linear, sequential, rule-governed, or conforms to specific codes
|
|
|
Right hemisphere
|
more suited for multimodal and interregional processing, more suited for holistic or global processing of information
|
|
|
What are the Advantages of hemispheric lateralization?
|
efficiency and speed, no conflicts, saves cortical space, reduces redundancy
|
|
|
Hemispherectomy
|
regaining a loss function often occurs at the expense of other functions
|
|
|
organizing effects of sexual hormones
|
The effects of early exposure to hormones during prenatal develoment
|
|
|
Activating effects
|
The effects of hormones later in development (puberty)
|
|
|
Spatial task performance is decreased in what?
|
Males with elevated testosterone levels
|
|
|
Spatial task performance is increased in what?
|
Females with elevated testosterone levels
|
|
|
High Estrogen is associated with what?
|
Better delayed verbal memory
|
|
|
Higher testosterone is associated with what
|
Better verbal fluency.
|
|
|
Congential Adrenal Hyperlasia (CAH)
|
visuspatial performance in girls with CAH was higher. Boys with CAH had lower visuospatial performance
|
