Over more than a century of research has established the fact that sleep benefits the
retention of memory. In this review we aim to comprehensively cover the field of “sleep and …

It is difficult to think of any behavioural process that is more intrinsically important to us than
attachment. Feeding, sleeping and locomotion are all necessary for survival, but humans …

Comparative psychologists interested in the evolution of intelligence have focused their
attention on social primates, whereas birds tend to be used as models of associative …

A common feature of many species is the formation of a mutual attachment between infant
and caregiver that ensures that the pair maintains contact. This attachment formation must …

The avian caudolateral neostriatum (NCL) was first identified on the basis of its dense
dopaminergic innervation. This fact and data from lesion studies have led to the notion that …

The present review provides an overview of the distribution of dopaminergic fibers and
dopaminoceptive elements within the avian telencephalon, the possible interactions of …

It is our goal in this text to use evolutionary principles as a unifying theme for exposing
students to a number of approaches to the field of animal behavior and to demonstrate that …

Auditory and vocal regulation of gene expression occurs in separate discrete regions of the
songbird brain. Here we demonstrate that regulated gene expression also occurs during …

Despite the long, separate evolutionary history of birds and mammals, both lineages
developed a rich behavioral repertoire of remarkably similar executive control generated by …

The transition from wakefulness to sleep is marked by pronounced changes in brain activity.
The brain rhythms that characterize the two main types of mammalian sleep, slow‐wave …
