1. Induction of Zenk protein expression within the nucleus taeniae of the amygdala of pigeons following tone and shock stimulation
In this study, we evaluated the expression of the Zenk protein within the nucleus taeniae of the pigeon’s amygdala (TnA) after training in a classical aversive conditioning, in order to improve our understanding of its functional role in birds. Thirty-two 18-month-old adult male pigeons (Columba livia), weighing on average 350 g, were trained under differe

2. Organização temporal em processos de condicionamento classico aversivo e na expressão da proteina Zenk no hipocampo de pombos (C. livia) / Temporal organization of classical aversive conditioning processes and expression of Zenk protein in the hippocampus of pigeons (C. livia)
Part of the knowledge about the mechanisms and neural basis of learning, memory and amnesia is based on the investigation of neural correlates of the behavior of non human animals in aversive situations. Moreover, many studies suggest that these behavioral processes are affected by the circadian timing system. The procedures of classical aversive conditionin

3. Contact Call-Driven Zenk Protein Induction and Habituation in Telencephalic Auditory Pathways in the Budgerigar (Melopsittacus Undulatus): Implications For Understanding Vocal Learning Processes
Expression of the immediate early gene protein Zenk (zif 268, egr-1, NGF1A, Krox24) was induced in forebrain auditory nuclei in a vocal learning parrot species, the budgerigar (Melopsittacus undulatus), when the subjects either listened to playbacks of an unfamiliar contact call or to a contact call with which they had been familiarized previously.

4. Decrements in auditory responses to a repeated conspecific song are long-lasting and require two periods of protein synthesis in the songbird forebrain.
Earlier work showed that playbacks of conspecific song induce expression of the immediate early gene ZENK in the caudo-medial neostriatum (NCM) of awake male zebra finches and that this response disappears with repeated presentations of the same stimulus. In the present study, we investigated whether repetitions of a song stimulus also elicited a decrement i

5. Localized neuronal activation in the zebra finch brain is related to the strength of song learning
Songbirds (Oscines) learn their songs from a tutor. It is not known where in the brain the memories of these learned sounds are stored. Recent evidence suggests that song perception in songbirds involves neuronal activation in brain regions that have not traditionally been implicated in the control of song production or song learning, notably the caudal part
