Structural Brain Imaging Methods
Techniques like CT, MRI, and DTI that provide static images of the brain's structure.
Functional Brain Imaging Methods
PET, fMRI, and EEG are examples of this type of method, which provides dynamic information about brain activity.
TMS (Transcranial Magnetic Stimulation)
Stimulation technique using magnetic fields.
Neuropsychology
Studying the relationship between brain lesions and behavior.
Temporal Resolution
Refers to the precision of a measurement with respect to time.
Spatial Resolution
Refers to the precision of a measurement with respect to location or size.
Electroencephalography (EEG)
EEG
Magnetoencephalography (MEG)
MEG
Event-Related Potentials (ERPs)
Signals derived from EEG recordings that are time-locked to specific events or stimuli and require averaging across multiple trials.
Computed Tomography (CT)
Technique involving X-rays to construct structural images of the brain.
Magnetic Resonance Imaging (MRI)
A neuroimaging technique that uses magnetic fields and radio waves to create detailed images of the brain's structure.
Diffusion Tensor Imaging (DTI)
Measures the diffusion of water molecules in the brain to visualize white matter tracts.
Functional MRI (fMRI)
A functional neuroimaging technique that detects changes in blood flow to identify brain regions active during specific tasks.
Positron Emission Tomography (PET)
Functional imaging technique that uses radioactive tracers to map brain activity.
BOLD
The blood oxygen level-dependent signal; the signal measured by fMRI.
Lesion Method
A method in which brain function is inferred by observing the effects of brain injury.
Traumatic Brain Injury (TBI)
Impairment in brain function as a result of mechanical force.
Closed Head Injury
Brain injury caused by impact where the skull is not penetrated.
Open Head Injury
Brain injury where an object penetrates the skull.
Primary Brain Injury
Brain injuries that occur at the moment of impact.
Secondary Brain Injury
Brain injuries that evolve over time after the initial impact and can involve hypoxia.
Glasgow Coma Scale (GCS)
A scale used to assess the level of consciousness in patients with head injuries.
Stroke
Cerebrovascular accident caused by rupture or blockage of a blood vessel in the brain.
Dementia
Progressive decline in cognitive function, often associated with Alzheimer's disease or other disorders.
Tumor
A mass of cells whose growth is uncontrolled and serves no useful function
Ischemic Stroke
Cerebrovascular accident caused by occlusion of blood vessel
Hemorrhagic Stroke
Cerebrovascular accident caused by rupture of cerebral blood vessel
