Jau ilgu laiku zin\u0101tniekus interes\u0113ja, k\u0101 zieme\u013cbrie\u017ei saglab\u0101 aktivit\u0101ti ziemas Arktik\u0101, kam\u0113r daudzi citi dz\u012bvnieki iet ziemas miega, un kas \u013cauj tiem vasar\u0101 b\u016bt modriem gandr\u012bz 24 stundas diennakt\u012b. Lai noskaidrotu \u0161o jaut\u0101jumu, Norv\u0113\u0123ijas un \u0160veices biologu komanda gada garum\u0101 izp\u0113t\u012bja \u010detru Eir\u0101zijas tundras zieme\u013cbrie\u017eu (Rangifer tarandus tarandus) m\u0101t\u012b\u0161u uzved\u012bbu, izmantojot neinvaz\u012bvu elektroencefalogr\u0101fiju (EEG).<\/p>\n

Rezult\u0101t\u0101 noskaidroj\u0101s, ka brie\u017ei da\u017e\u0101dos gadalaikos gul\u0113ja aptuveni vien\u0101du laiku.
