Imaging techniques are help in the study of any organ of the body - They help you learn about the functioning of the organs
Invasive methods of studying the brain involve physically inserting instruments or substances into the brain, such as electrodes or drugs. Noninvasive methods, on the other hand, allow for studying the brain without direct penetration, using techniques like functional magnetic resonance imaging (fMRI) or electroencephalography (EEG).
One of the biggest myths is that we only use 10% of our brain. In reality, modern brain imaging techniques have shown that most of the brain is active even when we are not actively thinking. This myth likely originated from a misinterpretation of early brain research.
Functional magnetism refers to the use of magnetic resonance imaging (MRI) techniques to measure brain activity by detecting changes in blood flow. This method enables researchers to study brain function and connectivity in response to various tasks or stimuli.
Advanced microscopy techniques such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM) are now commonly used in place of electron and field ion microscopes. These techniques offer high-resolution imaging of surfaces at the atomic and molecular level without the need for a vacuum environment like in traditional electron microscopy. Additionally, techniques like correlative microscopy, combining different imaging modalities, are also gaining popularity for studying biological samples in situ.
A hypo-metabolic area in the brain refers to an area that is functioning at a lower metabolic rate compared to surrounding brain regions. This can indicate reduced activity or dysfunction in that specific brain region, which may be associated with various neurological conditions or diseases. Imaging techniques like PET scans can help to identify hypo-metabolic areas in the brain.
A brain imaging technique is a method used to visualize and examine the structure and function of the brain. Examples include MRI, CT scan, PET scan, and fMRI. These techniques are valuable in diagnosing neurological disorders, studying brain activity, and understanding the brain's anatomy.

Functional Magnetic Resonance Imaging (fMRI)
fMRI has moderate temporal resolution compared to other imaging techniques. It can track brain activity in seconds, but techniques like EEG have higher temporal resolution, measuring brain activity in milliseconds.
Aggressive driver imaging refers to the use of different imaging techniques, such as functional magnetic resonance imaging (fMRI) or positron emission tomography (PET), to better understand the brain activity and neural correlates associated with aggressive driving behavior. By studying brain patterns, researchers aim to identify potential biological markers that may help in predicting or assessing aggressive driving tendencies.
MRI - Magnetic Resonance Imaging
Cells can be studied using various methods including microscopy (light, electron, fluorescence), cell culture techniques, molecular techniques (PCR, sequencing), biochemical assays (ELISA, Western blot), and imaging techniques (confocal microscopy, flow cytometry). Each method provides different insights into cellular structure, function, and behavior.

field of neuropsychology to examine how brain damage or dysfunction affects cognitive functions, emotions, and behaviors. They utilize brain imaging techniques such as MRI and fMRI to observe brain activity and understand the neural basis of psychological processes. By studying the brain, psychologists gain insights into how our biology influences our thoughts, feelings, and actions.
Neuroscience. This perspective examines how brain structures and functions influence behavior, emotions, thoughts, and other psychological processes. Neuroscientists use techniques such as brain imaging and electrophysiology to explore these relationships.
EEGs
Imaging studies commonly used to diagnose movement disorders include MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans of the brain. These imaging modalities can help identify any structural abnormalities or changes in the brain that may be causing the movement disorder. Additionally, functional imaging studies like PET (Positron Emission Tomography) or SPECT (Single Photon Emission Computed Tomography) scans can provide information about brain activity related to movement disorders.
