A Protocol for Ultra-High Field Laminar fMRI in the human brain

Ultra-High Field (UHF) neuroimaging affords the sub-millimetre resolution that allows us to interrogate brain computations at a finer scale than that afforded by standard fMRI techniques. Here we present a step-by-step protocol for using UHF imaging to measure brain activity in the human brain. We outline how to preprocess the data and correct for vasculature-related confounds to improve the spatial accuracy of the fMRI signal. The pdf file contains the fMRI sequence we used to measure the brain activity.

超高场（Ultra-High Field, UHF）神经成像技术具备亚毫米级分辨率，能够以比常规功能磁共振成像（functional Magnetic Resonance Imaging, fMRI）技术更精细的尺度探查大脑的计算活动。本研究提供一套分步操作方案，用于借助超高场神经成像技术检测人类大脑的神经活动。我们详细阐述了如何对成像数据进行预处理，并校正血管相关的混淆因素，以提升功能磁共振成像信号的空间精度。本数据集附带的PDF文件包含了本次实验中用于检测大脑活动的功能磁共振成像序列。
