All scientific research needs to go through years of arguments and debates to polish itself, including research of functional magnetic resonance imaging (fMRI) in human brain. fMRI is one of the state-of-the-art noninvasive techniques to investigate brain functions of human and animals. Since it is difficult and hardly practical to record vivo neural activity from human brain, fMRI provides an substitute measurement of neural activity which is based on the haemodynamic response in blood flow during the neural activity, also known as bloodoxygen-level dependent (BOLD) signal.

Functional magnetic resonance imaging (fMRI) is recently developed and applied to measure the hemodynamic response related to neural activity. The fMRI can not only noninvasively record brain signals without risks of ionising radiation inherent in other scanning methods, such as CT or PET scans, but also record signal from all regions of the brain, unlike EEG/MEG which are biased towards the cortical surface. This paper introduces the fundamental principles and summarizes the research progress of the last year for imaging neural activity in the human brain. Aims of functional analysis of neural activity from fMRI include biological findings, functional connectivity, vision and hearing research, emotional research, neurosurgical planning, pain management, and many others. Besides formulations and basic processing methods, models and strategies of processing technology are introduced, including general linear model, nonlinear model, generative model, spatial pattern analysis, statistical analysis, correlation analysis, and multimodal combination. This paper provides readers the most recent representative contributions in the area.

It has long been observed that experience influences aesthetic evaluations. Psychological research has found multiple examples of experts and nonexperts forming different liking responses to similar stimuli. It remains unclear, though, precisely why experts evaluate objects they are experts on differently from people who are not experts. In the article under discussion, using functional magnetic resonance imaging, the authors demonstrated that, compared to non-architects, architects exhibited higher levels of neural activity in the reward systems when tasked with evaluating their liking of buildings but not when tasked with evaluating the attractiveness of faces.
