About this Research Topic
This article collection will expand our understanding of how learning occurs between previously established and opposing circuits by highlighting recent findings and advances. The goal is to demonstrate some commonalities between different experimental approaches in investigating association of opposing circuits. For instance, do some forms of antagonistic response pairing produce more of an alpha conditioning, in that one of the responses is weakened, while the other is strengthened. Or is it more common that some form of beta conditioning is seen, where there is an emergence of a new response that results from pairing? Further, when opposing circuits are activated sequentially in conditioning, does this reverse the previous learned experience, or produce an intermediate condition that is different? With recent work demonstrating learning-induced alterations in gene expression via epigenetic mechanisms, this infers the possibility that learning circuits somehow have a form of identity based on experience. This leaves open the possibility that plasticity itself may be nuanced depending on the previous experience coded within the circuit. By understanding more about how these forms of plasticity or conditions for neural change occur, this will inform both future research into learning and neuroplasticity, as well as provide insights into clinical approaches that rely on a behavioral or learning component.
This Research Topic will comprise several different article types in order to stimulate discussion and to bring together work from across disciplines on the topic of oppositional conditioning. Article types including: Original Research, Review, Mini-Review, Hypothesis-and-Theory, Perspective, Clinical Trial, Case Report and Opinion articles will be considered for the following topics (or a related topic):
• Combination of reward and fear learning, counter-conditioning or associations of opposing behavioral responses.
• Behavioral and mechanistic investigations of behavioral flexibility.
• Calcium imaging of competing or opposing response circuits.
• Clinical studies of counter-conditioning or antagonism of fear responses.
• Computational modelling of multiple or counter-response conditioning.
Keywords: Parallel Memory, Competition, Opposition, Antagonistic Responses, Neural Circuits
