Jack H. Skirball Chair Professor in Brain Research
Human Cognitive Neuroscience Lab

The focus of the Leon Deouell’s Human Cognitive Neuroscience Lab is on the interface between automatic, non-conscious stages of information processing in the brain and conscious perception and action. This interest stems from observations and empirical studies of stroke patients mainly with right hemisphere damage and unilateral neglect, who lose the ability to attend and respond to the part of space opposite their lesion. To investigate what types of structures and processes need to be intact to support the transition from background processing to conscious awareness of events in the environment, we use performance measures, eye movements, electrophysiology (EEG and intracranial ECOG) and functional MRI. The participants in our studies are young adults (students), patients, and age matched controls. Currently, our studies focus on the how regularity affects the processing of incoming stimuli, why we sometimes miss information that we see in free viewing (using eye-fixation-related-potentials), and how visual information is represented in the brain beyond the first moment of recognition.

A postdoctoral position is available at the Human Cognitive Neuroscience Laboratory (HCNL) under the supervision of Prof. Leon Deouell. Our lab investigates perceptual and occasionally also decision making processes and their relation to conscious awareness. What determines whether an event is consciously available or not? What is the difference between processing with and without conscious awareness? We aim to investigate these questions using experimental psychology while employing multiple brain imaging modalities, especially EEG combined with simultaneous eye tracking, intracranial ECOG, and fMRI. The successful candidate will join a recently funded project trying to bridge the signals acquired using these different modalities.

Requirements: Candidates must hold a PhD degree in the field of cognitive neuroscience or a related discipline and have prior experience in human electrophysiology (EEG/MEG/ECOG).

Experience with fMRI is an advantage. Candidates should be driven and able to work independently yet enjoy the collaborative spirit of the lab. Candidates should be proficient in English.

Further details: Possible start of employment: immediate For more information, please contact:
