The NUMMENMAA LAB at Turku PET Centre is dedicated to unraveling the neurochemical and functional mechanisms that support human emotions, as well as their dysfunction in various psychiatric and neurological disorders. The lab focuses on studying system-level biological circuits from the brain to the periphery, particularly the endogenous opioid, dopamine, and endocannabinoid systems.
The lab combines state-of-the-art nuclear medicine imaging with advanced signal analysis, large-scale neuroinformatics, and modern clinical psychology to measure the brain's molecular organization and function using PET and MRI. It also conducts behavioral research using eye tracking and mobile recording techniques. Led by Lauri Nummenmaa, the lab is funded by the European Research Council, Academy of Finland, and other institutions.
DeepSeek-VL2 is an advanced series of large Mixture-of-Experts (MoE) Vision-Language Models designed for advanced multimodal understanding. It demonstrates superior capabilities across various tasks, including visual question answering, optical character recognition, document/table/chart understanding, and visual grounding. The model series includes three variants with 1 billion, 2.8 billion, and 4.5 billion activated parameters respectively.
Psychtoolbox is an open source solution that extends MATLAB and Octave with functions for research-grade stimulus presentation and response collection for neuroscience and other application domains. The core routines of Psychtoolbox offer reliable, precisely-timed, and efficient functions for stimulus presentation and response collection across different modalities.
The Department of Psychology at Northwestern University is dedicated to research and teaching in the field of psychology, covering a range of research directions from non-human primate vocalizations and cognition to political bias. Our faculty and students conduct cutting-edge research across various domains, including cognitive, social, developmental, and clinical psychology, providing profound insights into human behavior and mental processes.
