Inherited Memory in Birds

Corticosterone and memory in birds

Spatial learning and memory in birds.

Behavioral ecologists, well versed in addressing functional aspects of behavior, are acknowledging more and more the attention they need also to pay to mechanistic processes. One of these is the role of cognition. Song learning and imprinting are familiar examples of behaviors for which cognition plays an important role, but attention is now turning to other behaviors and a wider diversity of s...

Was Dinosaurian Physiology Inherited by Birds? Reconciling Slow Growth in Archaeopteryx

BACKGROUND Archaeopteryx is the oldest and most primitive known bird (Avialae). It is believed that the growth and energetic physiology of basalmost birds such as Archaeopteryx were inherited in their entirety from non-avialan dinosaurs. This hypothesis predicts that the long bones in these birds formed using rapidly growing, well-vascularized woven tissue typical of non-avialan dinosaurs. ME...

Sleep and memory in mammals, birds and invertebrates

Sleep supports memory consolidation. Based on studies in mammals, sleep-dependent consolidation has been conceptualized as 'active system consolidation'. During waking, information is encoded into an initial store (hippocampus). During subsequent sleep, some of the newly encoded memories are selected to be reactivated and redistributed toward networks serving as long-term store (e.g., neocortex...

Serological Monitoring of Avian Influenza in Migratory Birds of Iran

  Although migratory waterfowl is well known to be a major reservoir for avian influenza virus (AIV), there are only few recently published reports about the seroprevalence of AIV in this group of birds. To investigate the AIV antibody status in migratory waterfowl of Iran, we collected 217 serum samples from 25 different species of waterfowl during 2003 and 2004. These serum samples were teste...
