Investigating the structure and function of the brain
Our understanding of the inner workings of the human brain is increasing exponentially. This is due in no small part to the rapidly advancing technology that has evolved from the application of engineering to neuroscience. This chapter reviews some of the more influential tools that are in widespread use in research institutes throughout the world. Beginning with the basics of electrophysiology, a broad overview of the current methods for resolving and modulating neural activity in the fields of imaging and brain stimulation is presented. Special attention is paid to temporal and spatial resolution, i.e., the capacity of the technologies to resolve small detail in time and space. The chapter concludes with a discussion of technical obstacles and future directions.
