This tutorial describes how to analyze a simple fMRI dataset. To complete this tutorial you will need: MATLAB installed on your computer. SPM installed on your computer. Download and extract the sample dataset that includes the fMRI data (in NIfTI format), an anatomical scan (also T1) and text files that describe the timing.
23 mar 2010 · A blocked design consists of different blocks of trials of the same stimulus type and is characterized by three factors: the length of blocks, i.e., number of trials per blocks, the ordering of task and rest blocks, and the time between trials within one block.
Block design fMRI modelling¶ Model specification and review¶ This tutorial uses the same auditory data described in the fMRI preprocessing tutorial. Before attempting this tutorial you will need a copy of the preprocessed data. Either follow the steps in the fMRI preprocessing tutorial or download a copy of the preprocessed data from here.
Cognitive studies employing fMRI can be performed in two ways: (1) in block designs, which are analogous to the way PET studies are performed, either epochs of related stimuli are presented,...
This tutorial describes how to analyze a simple fMRI dataset. To complete this tutorial you will need: FSL installed on your computer (included with Lin4Neuro).
We conduct sample size determination and power analysis for a balanced incomplete block design in much the same fashion as for a randomized complete block design. The denominator degrees of freedom for the omnibus \(F\)-test are \(\text{df}_\text{res}=bk-b-k+1\).
Block or event-related tasks¶ Traditional task fMRI typically uses block or rapid event-related designs to measure differences in brain responses resulting from a particular experimental manipulation.
