Cortex Functioning Flashcards
Limbic Cortex Function
Homeostasis-Olfaction-Memory-Emotions/Drives
Primary Motor Location
Precentral gyrus in frontal lobe
Primary Somatosensory Location
Postcentral gyrus in parietal lobe
Primary Visual Location
Banks of calcarine fissure in occipital lobe
Primary Auditory Location
Transverse gyrus of heschl in temporal lobe
Unimodal Association
High order processing of modality-specific sensory information in areas adjacent to primary sensory areas; Proprocessing/planning of motor functioning in areas adjacent to primary motor
Heteromodal Association
Integrates multimodal information from unimodal association areas and limbic system; integrates complex sensory/motor information with emotion, motivation and drives; pr-frontal cortex and lateral temporal-parietal-occipital area
Receptive Language
language processing of information which results in comprehension
Receptive Auditory Comprehension Pathway
Primary auditory area (Heschl’s gryrus) –> Wernicke’s area (superior temporal gyrus)
Wernicke’s Area
Maps sounds to meaning
Expressive Language
production of language with the intention of transmitting information to oneself or another person
Speech Production Pathway
Broca’s area (inferior frontal gyrus) –> Primary motor area (precentral gyrus)
Broca’s Area
Contains motor programs for speech
Repetition Pathway
Wernicke’s area –> arcuate fasciculus (white matter track)–> Broca’s area
Aphasia
Loss of previous acquired language functioning
