Physiology in Arizona – Part 1

This past weekend the Arizona Physiological Society held their 11th annual conference on the Tempe campus of Arizona State University. There were so many oral and poster presentations on comparative physiology that I will spend this entry focusing on the oral sessions. The Keynote address was given by Dr. Michael Joyner (Mayo Clinic, Rochester) who spoke about the importance of not just focusing research efforts on reductionist approaches, including many […]

#3: Zebra Finches Reward Themselves for singing well

The #3 post so far this year explored how zebra finches reward themselves for singing well:   Dopamine is an important hormone released from neurons involved in reward pathways. Researchers at Cornell University wanted to know if dopamine signaling was involved in how birds learn songs. Their findings, recently published in Science, present evidence that neurons in the brain of zebra finches do in fact decrease dopamine signals when the birds hear an […]

Zebra finches reward themselves for singing well

Dopamine is an important hormone released from neurons involved in reward pathways. Researchers at Cornell University wanted to know if dopamine signaling was involved in how birds learn songs. Their findings, recently published in Science, present evidence that neurons in the brain of zebra finches do in fact decrease dopamine signals when the birds hear an error in their song in comparison to when they sing ‘correctly’. The researchers also found […]
