Hari ikinyamakuru kitwa Current Biology kivuga ko impamvu rusake ibika ari uko mu mutwe wayo harimo isaha.

Rusake ifite isaha mu mutwe wayo uyibwira ko saa kenda zigeze, igahita ibika.

Ntibiyisaba  kubitekereza ho kabiri, ahubwo bihita byikora.

Ni nk’uko umuntu nawe umubiri we umutegeka gusinzira iyo ijoro riguye, ukamutegeka no kubyuka iyo igitondo gitangaje.

Igitangaje ni uko hari n’amafi yifitemo isaha iyabwira igihe runaka cyo kujya guturaga amagi no gukora ibindi akeneye kugira ngo abeho.

Uyu mwarimu nawe yaje kwemeza ko mu mutwe wa rusake habamo isaha kandi ikora neza kurusha iba mu muntu.

Isaha yo mu mutwe wa rusake ikora neza k’uburyo niyo rusake cyaba iri ahantu hari urumuri rwinshi kandi ari mu ijoro, bitayibuza kubika ku isaha isanzwe ibikoreraho.

Impamvu hano tuvuga urumuri ni uko urumuri rubuza ubwonko gusohora umusemburo ugena ibitotsi.
