  • Transcript of "9 telencephalona"

    1. 1. paleocortex, archicortex (allocortex ) – neurons in 3-5 layers neocortex (isocortex ) – neurons in 6 layers peripaleocortex et periarchicortex = mesocortex Telencephalic cortex - nomenclature
    2. 4. Location of main functional regions of telencephalic c ortex somatosenzory and senzory motor cortex of limbic forebrain association cortex
    3. 5. Cortex out of somatosenzory, senzory and motor areas as well as cortex of limbic forebrain injury of AC – it is difficult to test malfunction (changes) in psyche, behaviour and perception surroundings the oldest association cortex in parietal, temporal and occipital lobes – association of somatosenzory, senzory and motor functions the youngest association cortex – prefrontal cortex (a9-12) connection with other AC ASSOCIATION CORTEX
    4. 6. CORTICAL AREAS FOR SPEECH - I <ul><li>Broca‘s (motor) cortical area - g. front. inf. a44, 45 </li></ul><ul><li>for right-hander in L-hemisphere, for left-hander in R-hemisphere </li></ul><ul><li>normal function with M-I, M-II and PM </li></ul><ul><li>lesion - expressive aphasia – the lack of speech, but understanding is OK </li></ul><ul><li>Wernicke‘s (sensory) cortical area - a 22,39,40 in dominant hemi- </li></ul><ul><li>sphere </li></ul><ul><li>condition for normal function – intact visual and auditory cortex </li></ul><ul><li>lesion - receptive aphasia – the lack of understanding </li></ul>
    5. 7. CORTICAL AREAS FOR SPEECH - II
    6. 8. Limbic system – classic conception Papez‘s circuit (James Papez 1939) without specific function ncl. anterior thalami gyrus parahippocampalis hippocampus ncl. mamillaris tr. mammilo-thalamicus fornix gyrus cinguli

    9. 11. Basal ganglia striatum (neostriatum) ncl. caudatus putamen ncl. accumbens dorzal striatum ventral striatum globus pallidus (pallidum, paleostriatum) med. (internal) seg. lat. (external) seg. dorsal pallidum ventral pallidum substantia nigra ncl. subthalamicus ventralis tegmental area (VTA) pars compacta pars reticularis BASAL GANGLIA AND RELATED STRUCTURES
