Preregistration
If your work is not purely exploratory you might want to consider pre-registering your study. It can be a good way to decide in advance how you are going to collect and analyze your data. It helps make it clear to yourself and to others what part of your study was predicted (i.e confirmatory) and which part wasn't (i.e exploratory).
You can also opt for registered reports where you submit your methods to a journal and get reviews on the protocol before the data collection and analysis is conducted. At the moment there is a large number of journals that accept registered reports.
Pre-registering neuroimaging studies can be quite challenging and comes with a whole set of constraints that might be absent in other fields. Jessica Flannery has created a preregistration template based on the OHBM COBIDAS guidelines for fMRI studies. It is also available on Github in an Rmarkdown format
For examples of studies that were pre-registered you can search in the zotero libraries curated by the open science framework.
There is also a communit effort to keep track of the MRI and MEEG preregistrtions that exist in this spreadsheet and new entry can be added using this form.
You can find more information in this google drive on the effort to develop more templates for pre-reg in neuroimaging.
