Last-gasp transfers included Bologna signing Corinthians midfielder Ibson, Slovan Liberec striker Michael Rabusic to Verona and Francesco Fedato to Catania.
The transfer deadline passed on Friday night and some deals just squeezed in before the bell.
Bologna snapped up creative midfielder Ibson Barreto Da Silva from Corinthians.
The 30-year-old has played for Flamengo, Porto, Spartak Moscow and Santos over his career and tends to play in a trequartista role behind the strikers.
Bologna also loaned goalkeeper Federico Agliardi to Serie B outfit Cesena.
Hellas Verona signed Czech Republic international Rabusic from Slovan Liberec.
The 24-year-old centre-forward is seen as a valid alternative or partner for Luca Toni and this season scored three goals in eight Europa League games.
Verona were very active on deadline day, taking Marquinho on loan from Roma with option to buy half his contract and Ivan Pillud from Racing Avellaneda.
Catania and Sampdoria combined forces to take Italy Under-21 starlet Fedato from Bari.
The striker is 21 and considered one of the brightest prospects in Italian football, as he can play centre-forward or in more supporting roles on the left.
Sampdoria bought Fedato from Bari and immediately loaned him to Catania, where he will spend the next six months.
Elsewhere, Sassuolo brought in goalkeeper Ciro Polito from Atalanta and defender Alexis Zapata from Envigado as well as ex-Napoli captain Paolo Cannavaro.
Cagliari took defender Alessandro Bastrini on loan from Novara with option to buy at the end of the season.
Chievo signed Adrian Stoian from Genoa and Tiberio Guarente from Catania.
