An original method for studying cognitive abilities in largely wild passerine birds was developed. Studies of five crossbills (Loxia curvirostra) showed that this approach could be used to assess their ability to form concepts. All five cro...
Reversible and irreversible stages in the development of amnesia after disruption of the reactivation of associative memory in snails [0.03%]
