Cortex

Izingxenye ephambili we ama- cerebral zobuchopho kukhona iCape futhi ganglia subcortical. Njengoba lizungezwe izwe ventricles yabo lateral.

Phakathi Nenkabazwe sokunene nesobunxele ubabonisa ezijulile inkatho longitudinal. Ngo ukujula yalo iyona callosum Corpus. Its ifomu yezinzwa.

Cortex ikhanda ngobuchopho bomuntu ikhombisa isiphuku ingqondo. Kuyinto kwakhiwa grey daba by ezinzwa nge ezihlobene esukela kubo, futhi amaseli glial. Kukholakala ukuthi lona wamuva yenza umsebenzi ngokwesekala sezinzwa iqhaza exchange of izinto.

Cortex cerebral aphakeme, iphoyinti phylogenetic umbono, ukwakheka omncane isimiso sezinzwa esiyinhloko. I ukushuba we ungqimba kusuka nengxenye kuya kwangu ezintathu. Cortex cerebral yizigidi eziyizinkulungwane eziyishumi nambili noma nesishiyagalombili izinzwa.

Indawo yayo Imininingwane luyanda khona emifantwini eziningi. Bahlanganyela ucezu kobuso ama- futhi gyrus convex. Nenkabazwe ngamunye iyizingxenye ezine. Basuke ezakhiwe anemifantu ezintathu: Lateral, parietal, occipital nemaphakathi. Ngenxa yalokho, kwakhiwa i-occipital, yesikhashana, parietal futhi frontal iyizingxenye.

Lesi sakamuva itholakala phambi sulcus emaphakathi. Lobe parietal kunomkhawulo sulcus emaphakathi phambi, ezansi - uhlangothi, parietal-occipital - ngemuva. Lobe Temporal kuvimbela inkatho lateral ezijulile ngenhla. Lobe occipital at ngemuva parietal-occipital.

Ngenhla callosum Corpus kuyinto into emhlophe. Siqukethe lelivakalako, yemisipha associative commissural. Cortex has ezimbili indlela ukuxhumana amanga ngezansi CNS nge zenyuka, zehla izindlela. It sakhiwa imicu flat, ngaphesheya ama-.

Ezinye izindawo cortical ehlukile ukubaluleka sokusebenza. Ngesikhathi esifanayo cortex cerebral usebenza njengothisha yomkhakha owodwa. Nokho, awukho obusebenzayo kwasendaweni esiqinile. Ukuhlolwa ezilwaneni luye lwabonisa ukuthi ngemva kokubhujiswa izigaba ngazinye cortex, ngemva kwenkathi ethile yesikhathi, ezindaweni eziseduze nalihlahlandlela wesakhiwo ubhujiswe. Lesi sici lihlotshaniswa okusezingeni eliphezulu ductility amaseli.

Neocortex uthola kusuka zokwakheka yokwamukela inkanuko afferent. Ukuze yokwamukela ngamunye iyunithi therein oluhambisana indawo ngokuthi IP Pavlov "cortical analyzer-nucleus." izifunda Cortical lapho ukuthi akuphi, abizwa ngokuthi izindawo sezinzwa.

Ngo zadnetsentralnoy futhi perednetsentralnoy izindawo cortical ndawo yenuzi we analyzer motor. Kunenkolelo phezu receptor umsipha, le imisipha yohlaka nezihlanganiso injabulo.

Inkambu le analyzer isikhumba itholakala ngemuva sulcus central (kuzoni zadnetsentralnoy). Lihlobene nokubhekana ubuso ethintekayo, ubuhlungu kanye lokushisa ukuzwela.

Le ndawo ebanzi kakhulu ithatha indawo ye analyzers ubuso, ibhokisi izwi, izandla. Emincane kakhulu endaweni ababelwe analyzers ukumelwa shin, umlenze isiqu.

Isifunda occipital ndawo yenuzi we analyzer ezibukwayo, e-temporal - ukuzwa. INSIMU ukunambitha receptor etholakala eduze eceleni emseleni.

Imiphumela Movement kusukela ngokucasuka kwakhiwa okuyinto ngu ukusebenzisana ezindaweni lemizwa cortex motor. Itholakala phambi sulcus emaphakathi.

Nuclear ensimini analyzers ethulwa iziza uqweqwe lapho iningi semikhawulweni izindlela conductive. Ngaphandle izakhi mkhondo zitholakala. Zasezikusa pulses edonsa receptor efanayo faka analyzer ikhenela.
