FoxP2 expression in avian vocal learners and non-learners.

Most vertebrates communicate acoustically, but few, among them humans, dolphins and whales, bats, and three orders of birds, learn this trait. FOXP2 is the first gene linked to human speech and has been the target of positive selection during recent primate evolution. To test whether the expression pattern of FOXP2 is consistent with a role in learned vocal communication, we cloned zebra finch ...

Comparative Gene Expression Analysis Among Vocal Learners (Bengalese Finch and Budgerigar) and Non-Learners (Quail and Ring Dove) Reveals Variable Cadherin Expressions in the Vocal System

Birds use various vocalizations to communicate with one another, and some are acquired through learning. So far, three families of birds (songbirds, parrots, and hummingbirds) have been identified as having vocal learning ability. Previously, we found that cadherins, a large family of cell-adhesion molecules, show vocal control-area-related expression in a songbird, the Bengalese finch. To inve...

Non-literal Transfer Among Neural Network Learners

In recent years, neural networks have been used for a wide variety of applications, from medical screening [ Rutenberg, 1992, Weber, 1990 ] to municipal power grid security [ Atlas et al., 1990c ] . Furthermore, comparisons between neural networks and more traditional techniques have shown that neural networks often produce competitive, and sometimes superior, results ( [ Weiss and Kulikowski, ...
