Modern imaging technologies at MIT and MGH provide exciting new ways to understand the structure and function of the human brain. We will provide guided tours of our imaging facilities and show how we use these tools to look inside the brain. Our magnetoencephalography (MEG) system, capable of measuring magnetic fields a billionth of the magnetic field of earth, can record the simultaneous firing of thousands of cortical neurons as they form dynamic networks. Our magnetic resonance imaging (MRI) scanners provide high resolution images of the human brain as subjects perform a wide range of perceptual and cognitive tasks. Our positron emission tomography (PET) scanners can identify and localize specific molecules in the brain, revealing pathologies that may underlie many different brain disorders. Transcranial magnetic stimulation (TMS) is a noninvasive method that uses electromagnetic induction to create weak electric currents and cause depolarization or hyperpolarization in the neurons of the brain. Near infrared spectroscopy (NIRS) uses infrared light to illuminate tissue and infer brain activity through the diffusion and scattering of this light. We will introduce these technologies, offer lab tours and demonstrate data collection, and discuss their contribution to neuroscience.
