Methods of studying the nervous system The  Anatomical Method  involves staining neurons and then tracing their pathways. This method enables  researchers to map and make detailed constructs of the topography of the brain. The method of  Extirpation  involves cutting out or destroying brain tissue. Lashley used this method. He  would teach a rat a task, such as solving a maze. He would then make a lesion in one of the so called  association areas of the cerebral cortex in an attempt to determine where that particular bit of learned  behavior was stored. Electroencephalograph  or  EEG.  The EEG records electrical signals (brain waves) emanating from the  brain. Normal brain wave patterns can be identified as well as abnormal patterns.   There are four main wave  forms. Alpha waves

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
