Iro reticular activating system (RAS) ishungetedzo mukati me brain brain iyo inobatsira pakugadzirisa kusvinura, kana kuti kumutsa, kweuropi uye nokudaro inotora basa rinokosha pakuronga kumuka uye kurara-kuchinja.
Nzira dzinowanikwa mumutambo uyu dzinotanga kumucheto wepamusoro we brain brain uye dzinowedzera kuburikidza ne thalamus, uyezve kusvika kumusoro kweuropi, inonzi cerebral cortex.
Nzvimbo dziri mukati meuropi dzinoshanda sechikamu chegadziriro ino dzinosanganisira: midbrain reticular formation, nucleus mesencephalic, nucleus thalamic intralaminar, dorsal hypothalamus, uye tegmentum.
Kana iyi yakarasika, inogona kukonzera kurara kwakadzika, kushaya simba, kana kuti coma. Kusagadzikana kunogonawo kuita basa muchirwere chechirwere, kushungurudza, uye zvimwe zvinetso zvehope.
Iyo Inorayira Sei Kurara
Iro reticular activating system inobatsira uropi hwako kuti hugadzirire hupamhi hwemabasa kuitira kuti iwe unogona kusimuka mangwanani. Iwe unogona kufunga pamusoro payo sehutano hwako hwehuropi: Inobata kunze kwekunyaradza uye inokonzerwa nekuziva nekuziva. Kuti uwane iwe mangwanani, inopindura kune zvakasiyana-siyana zvinokonzera, zvakadai sezuva nemanzwi uye zvinokonzera pfungwa dzako kuti uchenjere. Muzuva rose, inokuchengetedza wakamuka uye wakamuka nekubatsira ubongo hwako huri kuitika kune iwe.
Dambudziko rekunyengera
Rimwe dambudziko rehope rinosanganiswa ne reticular activating system nderesepsie - chirwere chisingaperi chinokonzerwa nehutano husina kunaka hwekurara.
Izvi zvinopesana nehope-kumira kwechikamu kune chikamu nekuda kwechibvumirano chisingaiti chekuita shanduro yevanhu uye vanhu vane nhamba dzisina maturo vane nguva dzekurara uye dzisingadzorwi zvemasikati uye vanogona kurara chero nguva. Kuderedza dambudziko kunogona kuva nengozi, sezvo vanhu vane chirwere vanorara vasina chiziviso, izvo zvinogona kusanganisira panguva dzekutya, kufamba kana zvimwe mamiriro ezvinhu angaita kuti ivo nevamwe vave pangozi.
Kuti RAS Inogona Kuparadzwa sei
Iro reticular activating system inogona kukuvara nenzira shomanana. Imwe yeiyo apo munhu ane chirwere chinokonzera kuora mwoyo (TBI), semugumisiro wenjodzi kana chimwe chikonzero. Kuparara kweRAS kubva kuTBI hakuwanzogadziriswa, asi migumisiro inogona kuderedzwa kuburikidza nekurapwa kwekugadziriswa kunotarisirwa kurara, kurwadziwa, kutarisa uye kuisa mafungiro anotevera.
