Monitoring behaviorally relevant spatio-temporal activity patterns in prefrontal networks using in vivo wide field-microendoscopy (B04)

Subject Area Molecular Biology and Physiology of Neurons and Glial Cells
Term from 2015 to 2019
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 243553651
 

Project Description

Responding to predicted rewards is a basic mental process. Its impairment may result in impulsive and compulsive actions, both key features in many psychopathologies including addictions. When an animal is faced with alternative reward options sparsely distributed populations of neurons (ensembles) are activated in the medial prefrontal cortex (mPFC). Using molecular activity tagging and longitudinal in-vivo calcium imaging recording from mPFC subregions, we want to gain insight into the formation, specificity, distinction and plasticity of prefrontal ensembles involved in the choice for natural or drug rewards.
