Pfupisa nyaya yacho:  Kunyomba kunowanzorondedzerwa sorudzi rwakaderera zvikurusa rwehungwaru, asi kunoratidzika kuti unoda rudzi rwakarurama rwehungwaru pakutanga kuti ugone kukuziva. Masayendisiti ezvirwere zvetsinga akaziva nzvimbo iri muuropi inokosha pakuziva apo mumwe munhu ari kutaura achitsvinya. Vakaona kuti vanhu vane kukuvara kwechikamu chetsandanyama yokurudyi - chihomwe chechinhu chichena chiri pakati pecerebral cortex nezvimiro zviri pasi pecerebral cortex muuropi - havakwanisi kuziva kutaura kwokunyomba. Varwere vakabatwa nesitiroko vane kukuvara muchikamu che sagittal muchikamu chakarurama cheuropi (chakaratidzwa mumufananidzo uri pamusoro) vakanga vari varombo zvikuru mukucherechedza kutaura kwokunyomba pavanenge vachiteerera mitsara, maererano nokutsvakurudza kutsva. Vanorwara nesitiroko kazhinji kazhinji vanokuvadzwa munharaunda iyi youropi hwavo uye vanonetseka kuziva apo mhuri neshamwari vari kuva vanonyomba. Maererano nevatsvakurudzi vepaJohn Hopkins Medical School muBaltimore, mwero wokukuvadzwa kwechikamu ichi cheuropi unoratidzika kuva unotapura zvakananga mano omunhu okuziva kutaura kwokutuka. Kushandiswa nenzira inobudirira, kutsvinya kunogona kugovera kuderedza kunoparadza. Asi zvinoratidzawo kuti inogona kukurudzira zvikuru. Vashandi vanofanira kutsungirira mumwe wavanoshanda naye kana kuti mukuru webasa anotsvinya vane unyanzvi hwokugadzira zvinhu kupfuura vaya vasingadaro, tsvakurudzo yakawana kudaro. Vanzveri vanotaura kuti kuratidzirwa kutsoropodzwa kunoda "kuoma kunzwisisa kwokuziva" kwakawanda, kana kuti mano okuona zvinhu kubva pamativi anopfuura rimwe. Kuseka kwaiitwa nemashoko acho kwaibatsirawo kuti hasha dzisazombomuka. Fundo yacho ichashamisa munhu upi noupi ane mukuru webasa anovimba nokunyomba vashandi vake kuti awane zvakanakisisa mavari. Purofesa Argye Hillis, chiremba wezvirwere zvetsinga paJohn Hopkins Medical School uyo akatungamirira fundo yacho, akati: 'Kukundikana kuziva kutaura kwokunyomba kunogona kutungamirira kukusawirirana kukuru. 'Zvidzidzo zvishomanene zvapakuvamba zvakaratidzira kukuvara kweuropi kwakabatanidzwa nokuziva kwakakanganiswa kwokunyomba.' Kuvadziko yeperesenti mu sagittal stratum yakanga ine uremu hukuru zvikurusa uye yakanga iri bedzi chinhu chakazvimirira chokufanotaura chokuzivikanwa kwokutuka.' Kunyange kuvanhu vane utano hwakanaka kunyomba kungava kwakaoma kuziva uye dzimwe tsika dzinokuita...
Chikamu chokurudyi cheuropi chinonzi sagittal ndicho chinokosha pakuziva mashoko okunyomba. Masayendisiti anodzidza nezvezvirwere zvepfungwa paJohn Hopkins Medical School akaongorora uropi hwevarwere 24 vakabatwa nesitiroko uye akaedza mano avo okuziva kutaura kwokunyomba mumitsara 40. Sagittal stratum ibundu remashoko machena ari pasi pecerebral cortex. Zvakawanikwa izvi zvinogona kubatsira pakurapa varwere vane sitiroko vanoomerwa nokuona mashoko anoshoresa.
