Radial Glia and the Migration of Young Neurons in the Adult Avian Brain
<p>The adult bird brain continues to produce new neurons and integrate them into functional circuits. These cells are born in the ventricular zone (VZ) of the lateral ventricle, sometimes up to 5-6 mm away from the location were some of these neurons finally mature (Nottebohm, 1985). How do new …

Predictive Novelty Detection in Songbird Auditory Cortex
… sense of complicated sensory landscapes, the brain privileges the processing of novel stimuli. Detecting novelty is therefore a fundamental problem for the brain to solve. And it turns out to be complicated, as stimuli can be completely novel, or just novel relative to certain certain contexts …

Songbird Brain Organization and its Molecular Convergence with Humans for Vocal Imitation Learning
… two evolutionary processes within the adult avian brain and their impact on our understanding of the evolution of vocal imitation learning across species. Much is still unknown about the number and organization of unique neural cell populations in the avian brain. The avian dorsal and ventral …

Development of new methods to investigate the role of the avian hippocampus in memory formation in brown-headed cowbirds
… birds. A great deal of previous research on the avian hippocampus has examined its role in spatial memory. A question regarding avian hippocampal function that remains unanswered is, what is its role in encoding, retention, and retrieval of spatial information? To answer this question I, 1) …

Factors controlling the expression of central progesterone receptors
… of progesterone receptor (PR) expression in avian brain tissue. In the first study, glial cells taken from newly hatched ring doves (Streptopelia risoria) were cultured in vitro to examine their subsequent development and to identify those cells which expressed PR. Astrocytes, identified …

Expression of GABAA receptor subunit genes in the avian song system and their role in learning and memory
… mediators of inhibitory neurotransmission in the brain. In avian systems, 14 GABAA receptor subunits (α1-6; β2-β4; γ1, 2 and 4, δ and π) have been identified. These assemble into pentameric transmembrane structures with an intrinsic chloride-selective pore and are involved in the modulation of …

The design and assembly of neural circuits for vocal communication in songbirds
Unlike the human brain, which produces few neurons in adulthood, the brains of songbirds continue to produce new neurons throughout life. The function of these new neurons is not know, although it has been suggested that they endow the avian brain with a remarkable regenerative capacity that does …

Identification and characterization of glial and neuronal cells in vitro and in bone marrow
… characterize glial cells and neuronal cells in avian brain and mammalian bone marrow, respectively. The project has four major objectives: (a) to culture and maintain avian glial and neuronal cells up to 20 days, (b) to examine cell cultures using selective cytological markers for gliaj and …

Hypothalamic Mechanisms of Food Intake in Birds
… appetite associated factors into the avian brain via an intracerebroventricular (ICV) injection including gastrin releasing peptide, vasoactive intestinal polypeptide, neuropeptide AF, and prostaglandin D2. Additionally, I explored the effects of HAT on food intake, and on the efficacy …
