Umsebenzi sezinzwa Ephakeme. ikhaliphe

Brain - iyona "igunya" ephakathi nendawo yendlela esakha isimiso sezinzwa akuyona womuntu kuphela, kodwa futhi ezilwaneni ezinomgogodla. Yena yinhlanganisela nerve futhi glial amaseli, kanye nomgudu walo. Brain Physiology - inqubo eyinkimbinkimbi yokusebenza yezingxenye kwesakhiwo. Kwenethiwekhi ukhiqiza futhi icubungula omningi amaza electrochemical. Esikhathini ingaphakathi cranial elise cephalic ubuchopho, umgogodla elise umsele umgogodla. Ephakeme umsebenzi sezinzwa - umsebenzi kuphela zobuchopho. Kuphela elawula ukuziphatha umzimba imvelo. Lower umsebenzi sezinzwa iqondisa umsebenzi kwezitho zangaphakathi, ekusebenzelaneni kwabo.

Wonke umuntu, yebo, has a yomhlaba ocebile kwangaphakathi, izimpendulo zokuziphatha, izici ngokwengqondo. I. P. Pavlov wagomela ukuthi umsebenzi ephakeme sezinzwa kubangelwa umsebenzi hemispheres cerebral futhi izakhiwo subcortical ukuqinisekisa ukuthi konke ukuzibandakanya yomuntu nezwe ngaphandle, msize lokuzivumelanisa nokushintsha imvelo. Ososayensi bathole ukuthi ngesisekelo ukuziphatha kwabantu kukhona ingqondo - okunemibandela futhi ngaphandle kwemibandela (imizwelo engokwemvelo). Siyabonga kubo, umzimba aphendvule nethonya ethize zangaphandle.

Ukubambezeleka kwamiswa ikhaliphe unconditioned ngokuhamba kwemvelo. Iningi lazo afakiwe umsebenzi cishe ngokushesha emva kokuzalwa. Ezinye akhiwa inqubo nokuvuthwa amasistimu ezithile, ezinjengobulili obuhilela. Inxanxathela ikhaliphe unconditioned ngokuthi isazela, nakuba Pavlov waphikelela ngokuthi umehluko phakathi kwabo - umbandela nesenzakalo uyefana.

Umsebenzi ephakeme sezinzwa owawuqondene usosayensi into eyinhloko cwaningo. Njengoba ukucwaninga Pavlov wathola ukuthi kwakhiwa ngohlobo olukhethekile uxhumano zesikhashana ama- cerebral bedle umfutho njalo zobuchopho - reflex ekhondishina, kwakheka njengoba yokufuna isipiliyoni ngabanye okuyinto. Kukhona ngezigaba, owawuthi UR zihlukaniswe zibe:

• yemvelo kanye yokufakelwa;
• elula kulokulukhuni
• ukuphathwa kwabathintwayo futhi autonomic;
• imali, ukulandelela et al.

Ukuze le reflex moya kwamiswa, izimo ezidingekayo. Ngokuyinhloko, UR Kumiswa ngesisekelo BR ebizwe umfutho ngabandayo. CNS kumele kwakhiwa futhi ephelele. Umfutho kumele kwenzeke ngokuphindaphindiwe, ukwakha evelele excitation focus. Umzimba maqondana ukwakheka reflex moya sihamba izigaba othandana naye, isizukulwane kanye nokugcinwa.

Imfundiso reflex - eyisisekelo imodeli theory, lapho kungenzeka ukuba afeze umgomo wokuhlaziya GNI. Ukuphendula umzimba isehlane izindlela eziyisisekelo - izinqubo excitation futhi okusithiyayo, ogxile okuvela futhi ukushabalala ikhaliphe moya. Nerve izinqubo ezihlobene nomunye futhi nihlanganyele.

Ngokuvamile umsebenzi ephakeme sezinzwa kuchazwa nje kokuthi isistimu ephakeme sezinzwa. Lena sibi futhi kunalokho abafundile. Isimiso sezinzwa e ezincelisayo kungenzeka ephakathi neuropathy, Nokho, kungenye indaba.
