Neuroscience techniques are methods used to study the brain and nervous system. These techniques include functional magnetic resonance imaging (fMRI), which measures brain activity by detecting changes in blood flow, and electroencephalography (EEG), which records electrical activity in the brain through electrodes placed on the scalp. Other techniques involve positron emission tomography (PET), which uses radioactive tracers to visualize brain processes, and magnetic resonance spectroscopy (MRS), which analyzes the chemical composition of brain tissue. Each technique provides unique insights into brain function, helping researchers understand complex neurological conditions and cognitive processes.
