We propose that a lack of focus on imagery can either, at best, prolong the course of treatment for clients or, at worst, encourage clinicians to label clients as “resistant” because their images insulate negative affective responses. While these techniques should be lauded for alleviating the symptoms of countless clients, there are other clients who are not served by these treatments. This is best seen in the counseling techniques and interventions of self-talk, thought records and the ABC ( activating events, beliefs, consequences) model. Since oxygen is critical for your brain to function properly, NIRS can assist doctors in any clinical setting where brain oxygen levels may fluctuate.Although many evidence-based practices emphasize addressing the cognitive aspects of mental health disorders, research suggests that we may be missing helpful interventions that do not fall under the cognitive behavior therapy (CBT) model of “thoughts, feelings and behaviors.” Several predominant CBT models fail to emphasize mental imagery by continuing to equate thoughts only with verbal manifestations. It uses infrared light to detect variations in hemoglobin oxygen levels in your blood. Near-infrared spectroscopy (NIRS) monitors your brain’s oxygen saturation. MEG allows doctors to assess areas such as: Doctors use MEG to evaluate both spontaneous brain activity, as well as neuronal responses triggered by stimuli. This type of scan can locate and identify malfunctioning neurons in your brain. Magnetoencephalography (MEG) measures the magnetic field from neuron electrical activity. Each type of frequency appears on its own line and gives your doctor information about your brain activity. These electrodes detect electrical activity in your brain and send it to a computer where it creates a graph-like image. Before the scan, clinicians will attach small electrodes to your scalp that are attached to wires. This allows doctors to see trouble spots where glucose isn’t moving correctly.Īn electroencephalography (EEG) test measures your brain waves. Since your brain uses glucose as its primary fuel source, the tracer accumulates in areas of higher brain activity.Ī PET scan is able to see these tracers and observe how they move and accumulate in your brain.
TYPES OF IMAGERY OF BRAIN SERIES
MRIs display anatomic structure and fMRIs measure metabolic function.Ī computerized tomography (CT) scan is a series of X-ray images converted into cross-sectional images of your brain. It uses the magnetic field of the scanner to affect the magnetic nuclei of hydrogen atoms, so they can be measured and converted into images. These modern brain imaging techniques enable doctors to map out the regions and functions of your brain in a non-invasive way.įunctional magnetic resonance imaging (fMRI) can detect changes in blood flow and oxygen levels that result from your brain’s activity. It doesn’t require invasive steps and often simply involves laying down and being still while the scan takes place around you. One of the benefits of brain imaging is how easily it can be performed. functional near-infrared spectroscopy (fNIRS).electroencephalography (EEG) and magnetoencephalography (MEG).
functional magnetic resonance imaging (fMRI).Since then, neuroimaging techniques have gotten increasingly more sophisticated, and are an important tool for neurology and mental health specialists.Ĭommonly used brain imaging techniques are:
This early EEG was able to detect electrical waves in the brain that would rise and fall as different brain cells communicated with each other. The year 1924 marked the first human electroencephalography (EEG), recorded by German psychiatrist Hans Berger.
