Project description
The role of brain circuits in complex cognitive processes
Humans can associate previous experiences and stimuli with particular situations that help them adapt to changes in the environment. These also allow them to predict future events. However, the mechanisms implicated in the encoding and storing of these complex cognitive processes remains poorly understood. The EU-funded HighMemory project aims to assess the role of the hippocampus and the cortex in higher-order conditioning processes by applying genetic, pharmacological, imaging and behavioural methodologies. Results will unveil the regulation of complex cognitive behaviour and help explain why specific stimuli have repellent or appealing value, although they have not been previously associated with negative or positive outcomes.
Objective
Animals and humans adapt to changes in the environment through the encoding and storage of previous experiences. Although associative learning involving a reinforcer has been the major focus in the field of cognition, other forms of learning are gaining popularity as they are likely more relevant and frequent in human daily choices. Indeed, associations between non-reinforcing stimuli represent the most evolutionarily advanced way to increase the chances of predicting future events and adapting individuals behavior. Animals are also able to form these higher-order conditioning processes, but more research is needed to understand how the brain encode and store these complex cognitive processes. In this project, I propose to study the role of hippocampo-cortical circuits in higher-order conditioning processes. These processes explain why subjects are often repulsed or attracted by stimuli, which do not have intrinsic repellent or appealing value and they were never explicitly paired with negative or positive outcomes. A proposed explanation of these ungrounded aversion or attraction is that these stimuli were incidentally associated with other cues directly reinforced, through a process called mediated learning (ML). However, with increased incidental associations, the subjects acquire more information, allowing them to separate the real saliences of the different stimuli. Therefore, ML evolves into reality testing(RT), a behavioral process that has been even less studied. These processes involve multiple brain regions and are characterized by accessible phases, making them perfect models to study the circuit-level regulation of complex behavior. By using genetic, pharmacological, imaging and mouse behavioral approaches (sensory preconditioning), HighMemory proposes to characterize at macro- (brain regions), meso- (cell-types) and micro-scale (activity changes), the causal involvement of hippocampo-cortical projections in higher-order conditioning processes.
