We like to think of this as contributing to the democratization of the cognitive neuroscience experiment. This opens dramatic new possibilities for neurotechnology and cognitive neuroscience education (at both University and High School levels), as well as more ambitious and larger-scale research and clinical applications using large numbers of devices, and/or in more naturalistic (i.e. In recent years, however, developments in hardware and software technologies are making it possible for many classic EEG cognitive neuroscience experiments to be conducted using a standard laptop/personal computer and a relatively cheap consumer-grade EEG device, with a combined minimum cost of less than 1000 dollars. The price tag for these items can easily extend into hundreds of thousands of dollars, which naturally places major limits on their acquisition and usage. 有关这些社会/科学/技术背景和轨迹的更多讨论,a) 请随时直接联系(请参阅下面的#Contact 信息)和 b) 留意即将发表的 eeg-notebooks 研究论文。Ĭonventional lab-based EEG research typically uses research-grade (often high-density) EEG devices, dedicated stimulus delivery software and hardware, and dedicated technicians responsible for operating this equipment. The old v0.1 is still available if you need it, in this repo. Note: eeg-notebooks underwent major changes to the API in v0.2. A series of tutorial videos will be coming soon!.For instructions on initiating an EEG stream see: initiating an EEG stream.For instructions on running experiments see: running experiments.For documentation see: documentation site.For an intro talk on the eeg-notebooks project see: JG's Brainhack Ontario presentation.The goal is to make cognitive neuroscience and neurotechnology more accessible, affordable, and scalable. The experimental protocols and analyses are quite generic, but are primarily taylored for low-budget / consumer EEG hardware such as the InteraXon MUSE and OpenBCI Cyton. Thank you so much.Democratizing the cognitive neuroscience experimentĮEG-Notebooks is a collection of classic EEG experiments, implemented in Python 3 and Jupyter notebooks. I just don’t know how to get started, and haven’t found any good demos online. If I could make a windmill stimulus that is always rotating at the same speed, and unrelatedly, adjust luminance for one of the colors, that would be wonderful. I think it would be easiest to rotate one windmill with fixed luminance, and overlay it on a circle with adjustable luminance. To change luminance, I am trying to modify this piece of code: contrast - How to use method of adjustment in Psychopy? - Stack Overflowīut I don’t know how to adjust luminance for one stimulus. What specifically went wrong when you tried that?: I’m not sure how to 1) create a rotating windmill stimulus, and 2) how to make the luminance for one of the colors (while the other is fixed) adjustable, from the participant’s point of view, and then record the final luminance. What did you try to make it work?: I am trying to make a rotating windmill of alternating red and green, such that when the two colors are perceptually isoluminant, the direction of the windmill spin changes. What are you trying to achieve?: Create a minimum motion task to test perceptual isoluminance (based on Cavanagh, et, al 1984 - (1984)%20perceived%20velocity%20of%20moving%20chromatic%20gratings.pdf) Standard Standalone?
