Best GLM figure in a poster?

Hi all, I'm going to present a poster with some preliminary behavioral data. About the analysis, I built a general linear model, with "group (3)", "type of stimulus (3)" and "gender" (2) as fixed...

Equality of Variances between groups?

Hi all, I have a 2x2x3 mixed design. Before running a 3-ways ANOVA, I checked the homoscedasticity of my data using the Levene's Test on JASP. Taking into account all the factors, the test...

What are some recent publications showing the predictor power of resting state brain acitivity for tasks done outside the MRI scanner?

Looking for recent articles (2018-2020) that showed resting state brain activity can predict cognitive task performance (e.g., attentional and executive functioning tasks) done in the lab AFTER...

Why is the impedance of ECoG electrodes tested at a frequency range from 1 Hz -100 kHz?

I am testing the impedance of a material that will be used for ECoG electrodes. I was told to test it at a frequency range from 1 Hz - 100 kHz but why is this range used? I wasnt able to find a...
