The position regards the lab of Marie Carlén, associate professor in the Department of Neuroscience, Karolinska Institutet, Campus Solna. Cognition encompasses a range of brain processes underlying our mental abilities and is a prerequisite for purposeful and goal-appropriate behavior. Proper cognitive processing is thus essential to many aspects of our everyday life, but little is known about how the brain's networks encode and enable behavior relying on cognition. Cortical functioning, and particularly the functions of the prefrontal cortex are considered central to cognition. Utilizing a systems neuroscience approach the lab of Marie Carlén studies the cellular logic of information processing in the prefrontal cortex (PFC). The studies are mainly performed in behaving mice using large-scale electrophysiological recordings or calcium imaging of neuronal activity. Optogenetics and circuit tracing are other central technologies, as is slice electrophysiology. The lab is recognized for its discoveries on inhibitory interneurons expressing parvalbumin and their role in cortical oscillations, cognition, and behavior. For more information see:

Your mission

Behavior, and its consequences, need to dynamically change to adapt to ever changing environmental affordances – a process described as learning. An influential theory in both neuroscience and computer science known as reinforcement learning postulates that actions with a positive outcome (e.g., reward) are reinforced, while outcomes with a negative outcome (e.g., punishment) are devalued. The neuronal basis of effective and complex learning in brain-wide circuits remains to be established. One current proposal states that the PFC through its widespread and reciprocal connectivity directs the dynamic and long-term adaptions in synaptic transmission underlying learning processes. The person we are seeking to hire will work in close collaboration with our lab members to decipher the role of the PFC in cortical learning. Neuronal signatures of learning in the mouse PFC and their transmission to downstream sensory cortical areas will be studied with large-scale calcium imaging and/or electrophysiology in behaving mice. The duties will also include viral tracing studies, animal colonies, and posthoc analysis of tissue, and more.

Your profile

We are seeking a highly motivated and creative person with a deep interest in conducting studies forwarding the understanding of the brain and with proven experience in the field of neuroscience, preferentially systems neuroscience. The work in the Carlén lab is highly collaborative and we are looking to add a team player enjoying active and close interactions with the colleagues in the research group.

Required: Education and relevant experience of basic neuroscience research in mammalian model animals (e.g., master’s degree in neuroscience or equivalent).

Desirable: Experience of recording and/or analysis of in vivo neuronal activity (e.g., LFP, EEG etc) and optogenetic manipulations. Experience of ex vivo electrophysiology or imaging is also of interest. Proficiency in programming and documented experience of advanced data analysis is meriting.
