Spontaanisti esiintyv\u00e4n hippokampuksen theeta-aktiivisuuden suhteellinen m\u00e4\u00e4r\u00e4 ennustaa oppimisen nopeutta klassisessa silm\u00e4niskuehdollistamisessa kaneilla. Mit\u00e4 enemm\u00e4n theetaa esiintyy, sit\u00e4 nopeampaa on my\u00f6s oppiminen. T\u00e4m\u00e4n tutkimuksen tarkoituksena oli tarkastella hippokampuksen theeta-aktiivisuuden vaihelukittumista ehdolliseen \u00e4rsykkeeseen klassisessa silm\u00e4niskuehdollistamisessa sek\u00e4 t\u00e4m\u00e4n yhteytt\u00e4 oppimiseen.

Tutkimuksessa k\u00e4ytettiin aikuisia naaraskaneja (New Zeland White rabbits), joita opetettiin silm\u00e4iskuehdollistamisen hippokampuksv\u00e4litteisell\u00e4 aikav\u00e4li -menetelm\u00e4ll\u00e4 (trace conditioning).

Toisin kuin aiempien tutkimusten perusteella oletettiin, vaihelukittuneissa theeta-vasteissa ei ollut eroja eri\nharjoitusryhmien v\u00e4lill\u00e4, eiv\u00e4tk\u00e4 vaihelukittuneet vasteet eronneet my\u00f6sk\u00e4\u00e4n oppineiden ja ei oppineiden kanien v\u00e4lill\u00e4.

Tutkimuksessa selvisi my\u00f6s, ett\u00e4 vaihelukittuminen harjoittelun alussa oli yhteydess\u00e4 oppimiseen harjoittelun keskivaiheilla. Vaihelukittuminen liittyy moniin oppimisen kannalta oleellisiin mekanismeihin, kuten v\u00e4r\u00e4htelyiden synkronisoitumiseen ja prosessoinnin tehokkuuteen, joiden voidaan ajatella vaikuttavan vaihelukittumisen ja oppimisen v\u00e4lisen yhteyden muodostumiseen.
