Cortex Flashcards
The dominant hemisphere usually coordinates with what?
Handedness (95% of people are left hemisphere dominant and 90% of people are right handed which is controlled by the left hemisphere)
What does the non-dominant hemisphere specialize in?
Non-verbal and non-mathematical functions (music appreciation, artistic activity and appreciation for the significance of sensory stimuli)
This part of the dominant hemisphere functions in the motor aspect of language production.
Broca’s area
Where does Broca’s area lie in?
Inferior frontal gyrus anterior to the face region of the precentral gyrus. On the dominant hemisphere
What does Wernicke’s area function in?
Language comprehension
Where is Wernicke’s area located in?
Part of the parietal lobe and superior temporal gyrus.
This cortex area plays a role in language, in particularly the focalization of sustained vowel sounds?
Supplementary Vowel Sounds
This prefrontal cortex division functions in self-awareness and executive function or goal oriented behavior
Lateral prefrontal region
This division of the prefrontal cortex functions in attaching or interpreting emotion within the context of the situation
Orbitofrontal region
What neurotransmitter pathway of the reticular system is associated with generalized arousal level?
Serotonin (raphe nuclei)
What neurotransmitter pathway of the reticular system is associated with selection of object of attention, based on goals.
Norepinephrine (locus ceruleus)
This neurotransmitter pathway of the reticular formation functions in selection of object of attention, based on goals
Ach (pedunculopontine nucleus)
This neurotransmitter pathway of the reticular system functions in motivation, motor activity and cognition
Dopamine (ventral tegmental area and substantia nigra)
This hemisphere is more dominant in terms of understanding the entire spatial map as it is interpreted by the proprioceptive and visual systems
Right hemisphere
