Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the organs and tissues in the body. It is widely used in medical diagnosis and research due to its ability to provide high-resolution images without exposure to ionizing radiation.
Functional Magnetic Resonance Imaging (fMRI) is a non-invasive neuroimaging technique that measures brain activity by detecting changes in blood flow, leveraging the fact that cerebral blood flow and neuronal activation are coupled. It provides high spatial resolution, allowing researchers to observe brain regions involved in various cognitive functions and mental processes in real-time.
Concept
Positron Emission Tomography (PET) is a non-invasive imaging technique that allows for the visualization and measurement of metabolic processes in the body by detecting gamma rays emitted from a radioactive tracer injected into the patient. It is widely used in oncology, neurology, and cardiology to assess tissue function and detect diseases such as cancer, Alzheimer's, and heart disease.
Concept
Computed tomography (CT) is a medical imaging technique that uses computer-processed combinations of multiple X-ray measurements taken from different angles to produce cross-sectional images of specific areas of a scanned object, allowing for detailed internal visualization. It is widely used for diagnostic and therapeutic purposes in various medical fields due to its ability to provide high-resolution images of bones, blood vessels, and soft tissues.
Concept
Electroencephalography (EEG) is a non-invasive technique used to record electrical activity of the brain, typically for diagnosing neurological conditions, studying brain functions, and monitoring brain health. It involves placing electrodes on the scalp to capture brain wave patterns, offering insights into brain states such as sleep, epilepsy, and cognitive processes.

It is particularly useful in localizing brain functions and identifying abnormal brain activity, such as in epilepsy research and pre-surgical planning.
Concept
Diffusion Tensor Imaging (DTI) is a type of MRI-based neuroimaging technique that maps and characterizes the three-dimensional diffusion of water as a way to probe the microstructural integrity of white matter in the brain. It provides critical insights into the connectivity and organization of neural pathways, aiding in the diagnosis and study of neurological disorders.
Concept
Brain connectivity refers to the complex network of neural pathways that link different regions of the brain, facilitating communication and coordination of cognitive, sensory, and motor functions. Understanding these connections is crucial for unraveling the intricacies of brain function and dysfunction, providing insights into neurological and psychiatric disorders.
Concept
Neuroplasticity refers to the brain's remarkable ability to reorganize itself by forming new neural connections throughout life, allowing it to adapt to new experiences, learn new information, and recover from injuries. This dynamic process underscores the brain's capacity for change and adaptation, challenging the long-held belief that brain development is static after a certain age.
Concept
Cognitive Neuroscience is an interdisciplinary field that explores the neural mechanisms underlying cognitive processes, integrating insights from psychology, neuroscience, and computational modeling. It aims to understand how brain function gives rise to mental activities such as perception, memory, language, and decision-making.
Concept
Neuroaesthetics is an interdisciplinary field that seeks to understand how the brain perceives and processes aesthetic experiences, such as art and beauty, by integrating neuroscience with psychological and philosophical insights. It aims to uncover the neural mechanisms underlying aesthetic appreciation and how these experiences influence human cognition and emotion.
Concept
Neurological outcomes refer to the results or consequences of a neurological condition or intervention, which can include changes in cognitive, motor, sensory, or emotional functions. Evaluating these outcomes is essential for understanding the efficacy of treatments and the progression of neurological diseases.
Concept
Angiographic vasospasm refers to the narrowing of cerebral blood vessels, often detected through imaging techniques following a subarachnoid hemorrhage. It is a critical condition that can lead to delayed cerebral ischemia, necessitating prompt diagnosis and management to prevent adverse neurological outcomes.
Concept
Visual Pathway Assessment is a clinical evaluation process used to analyze the integrity and functionality of the neural pathways responsible for vision, from the eyes to the visual cortex. It is essential for diagnosing and managing conditions that affect visual processing, such as optic neuropathies, tumors, or demyelinating diseases.
Concept
Lobar holoprosencephaly is a congenital brain malformation characterized by the incomplete separation of the brain's frontal lobes, leading to a range of developmental and neurological issues. It is the least severe form of holoprosencephaly, where individuals may have relatively mild facial anomalies and cognitive impairments compared to more severe forms.
Concept
Brain Network Dynamics explores how the brain's complex network of neurons dynamically changes and adapts over time, enabling cognitive functions and behaviors. It emphasizes the importance of understanding the temporal and spatial patterns of neural activity and connectivity in both health and disease.
