fMRI (functional magnetic resonance imaging) measures changes in blood flow in the brain, which is an indirect measure of neural activity.

EEG (electroencephalography) measures electrical activity in the brain, which is a direct measure of neural activity.

TMS (transcranial magnetic stimulation) uses magnetic fields to stimulate the brain, which can be used to study the effects of brain stimulation on behavior and cognition.

PET (positron emission tomography) uses radioactive tracers to measure brain metabolism, which can be used to study the relationship between brain activity and cognition.

Reaction time is a neuropsychological method that involves presenting stimuli to a patient and measuring their reaction time, which can be used to study the speed of information processing in the brain.

Accuracy is a neuropsychological method that involves presenting stimuli to a patient and measuring their accuracy, which can be used to study the accuracy of information processing in the brain.

Memory is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to remember the stimuli, which can be used to study the neural basis of memory.

Attention is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to attend to the stimuli, which can be used to study the neural basis of attention.

Decision making is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to make decisions, which can be used to study the neural basis of decision making.

Problem solving is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to solve problems, which can be used to study the neural basis of problem solving.

Creativity is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to generate ideas, which can be used to study the neural basis of creativity.

Language is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to understand language, which can be used to study the neural basis of language.

Speech is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to produce language, which can be used to study the neural basis of speech.

Object recognition is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to recognize objects, which can be used to study the neural basis of object recognition.

Face recognition is a neuropsychological method that involves presenting stimuli to a patient and measuring their ability to recognize faces, which can be used to study the neural basis of face recognition.
