Plasticity of sensory representations in the posterior insular cortex during fear learning
Aversively-motivated associative learning allows animals to avoid harm and thus ensures survival. Aversive learning can be studied by the fear learning paradigm, in which an innocuous sensory stimulus like a tone (conditioned stimulus, CS), acquires a nega ...
EPFL2023Fear Learning: An Evolving Picture for Plasticity at Synaptic Afferents to the Amygdala
Ralf Schneggenburger, Denys Osypenko, Shriya Palchaudhuri
Unraveling the neuronal mechanisms of fear learning might allow neuroscientists to make links between a learned behavior and the underlying plasticity at specific synaptic connections. In fear learning, an innocuous sensory event such as a tone (called the ...
SAGE PUBLICATIONS INC2022LTP of inhibition at PV interneuron output synapses requires developmental BMP signaling
Ralf Schneggenburger, Denys Osypenko, Christopher Clark, Evan Dean Vickers
Parvalbumin (PV)-expressing interneurons (PV-INs) mediate well-timed inhibition of cortical principal neurons, and plasticity of these interneurons is involved in map remodeling of primary sensory cortices during critical periods of development. To assess ...
2020Insular cortex processes aversive somatosensory information and is crucial for threat learning
Ralf Schneggenburger, Olexiy Kochubey, Denys Osypenko, Wei Tang, Michael Kintscher, Shriya Palchaudhuri, Emmanuelle Marie Brigitte Berret
Learning about threats is essential for survival. During threat learning, an innocuous sensory percept such as a tone acquires an emotional meaning when paired with an aversive stimulus such as a mild footshock. The amygdala is critical for threat memory f ...
