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 ...
EPFL2023Tuning perception and decisions to temporal context
Recent work suggests that serial dependence, where perceptual decisions are biased toward previous stimuli, arises from the prior that sensory input is temporally correlated. However, existing studies have mostly used random stimulus sequences that do not ...
Cambridge2023The effects of visual distractors on serial dependence
Attractive serial dependence occurs when perceptual decisions are attracted toward previous stimuli. This effect is mediated by spatial attention and is most likely to occur when similar stimuli are attended at nearby locations. Attention, however, also in ...
Rockville2023Attractive and repulsive serial dependence: The role of task relevance, the passage of time, and the number of stimuli
Visual decisions are attracted toward features of previous stimuli. This phenomenon, termed serial dependence, has been related to a mechanism that integrates present visual input with stimuli seen up to 10 to 15 s in the past. It is believed that this mec ...
2023Glutathione in the nucleus accumbens regulates motivation to exert reward-incentivized effort
Maria del Carmen Sandi Perez, Lijing Xin, Olivia Zanoletti, Simone Astori, João Pedro de Matos Rodrigues, Fiona Hollis, Pascal Steiner, Ioannis Zalachoras, Alina Veronika Irene Strasser, Eva Ramos Fernandez
Emerging evidence is implicating mitochondrial function and metabolism in the nucleus accumbens in motivated performance. However, the brain is vulnerable to excessive oxidative insults resulting from neurometabolic processes, and whether antioxidant level ...
2022Essays on the Role of Policy and Venture Financing in Clean Technology Innovation
This thesis aims to provide novel analyses and data that improve the understanding of the financing of investments in clean technologies. In particular, this thesis explores the role that private and public actors play in supporting young innovative firms. ...
EPFL2022Fear 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 INC2022Target cell-type specificity of a cortico-amygdala long range synaptic connection
An important function of the brain is to analyze sensory information, and to modulate animal behaviour according to previous experience. During processes of emotional learning, sensory percepts with a reinforcing quality, also called unconditioned stimuli ...
EPFL2021Visible-Light-Driven Catalytic Deracemization of Secondary Alcohols
Deracemization of racemic chiral compounds is an attractive approach in asymmetric synthesis, but its development has been hindered by energetic and kinetic challenges. Here we describe a catalytic deracemization method for secondary benzylic alcohols whic ...
