Textbook: psychology tenth edition in modules authored by david g. myers. Module 05: tools of discovery and older brain structures. How do neuroscientists study the brain"s connections to behaviour and mind: right now, your mental activity is emitting telltale electrical, metabolic, and magnetic signals that would enable neuroscientists to observe your brain at work. Lord chesterfield (1746) you must look into people, as well as at them. Eeg amplified readout of electric waves (like a showercap) 1: pet scan tracks radioactive glucose to reveal brain activity, mri scan uses magnetic fields and radio waves to show brain anatomy. As the spinal cord"s sensory input flows up to the thalamus, some of it travels through the reticular formation, which filters incoming stimuli and relays important information to other brain areas. Nerves from the left side of the brain are mostly linked to the right side of the body, and vice versa.
