Question 1:
How did Eric Kandel contribute to psychobiology?
Answer:
Kandel, Eric Richard – Contributions to Psychobiology
Eric Kandel, born November 7, 1929, is an Austrian-American neuroscientist who is the University Professor at Columbia University, where he is co-director of the Mortimer B. Zuckerman Mind Brain Behavior Institute. Kandel was awarded the 2000 Nobel Prize in Physiology or Medicine for his research on the neural mechanisms of memory. His work is considered a groundbreaking contribution to psychobiology.
Kandel’s research has focused on the cellular and molecular mechanisms underlying learning and memory in the simple nervous system of the sea slug Aplysia californica. He has shown that learning involves changes in the strength of connections between neurons, and that these changes are mediated by changes in the expression of genes. Kandel’s work has revolutionized our understanding of the biological basis of learning and memory, and has made him one of the most influential neuroscientists of the 20th century.
Question 2:
What were the specific mechanisms identified by Kandel’s research?
Answer:
Kandel’s Research – Mechanisms of Memory
Kandel’s research identified several specific mechanisms that are involved in learning and memory. These mechanisms include:
- Long-term potentiation (LTP): A long-lasting increase in the strength of connections between neurons that is induced by high-frequency electrical stimulation.
- Long-term depression (LTD): A long-lasting decrease in the strength of connections between neurons that is induced by low-frequency electrical stimulation.
- Synaptic tagging: A process that allows neurons to identify synapses that have been recently active and to strengthen these synapses through LTP.
- Transcription factors: Proteins that regulate the expression of genes and that are involved in the formation of new memories.
Question 3:
How has Kandel’s research advanced our understanding of the biological basis of learning and memory?
Answer:
Kandel’s Research – Impact on Understanding of Learning and Memory
Kandel’s research has had a profound impact on our understanding of the biological basis of learning and memory. His work has shown that learning and memory are not simply the result of changes in the electrical activity of neurons, but that they also involve changes in the structure and function of synapses and in the expression of genes. This work has revolutionized our understanding of how the brain works and has led to the development of new treatments for memory disorders.
