D015225. Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers. Arrays of SQUIDs (superconducting quantum interference devices) are currently the most common magnetometer ...
Electroencephalography. Epileptic spike and wave discharges monitored EEG. [ edit on Wikidata] Electroencephalography (EEG) [ 1 ] is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex ...
An event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. [ 1 ] More formally, it is any stereotyped electrophysiological response to a stimulus. The study of the brain in this way provides a noninvasive means of evaluating brain functioning.
Engineering psychology, also known as Human Factors Engineering or Human Factors Psychology, is the science of human behavior and capability, applied to the design and operation of systems and technology. [ 1 ] As an applied field of psychology and an interdisciplinary part of ergonomics, it aims to improve the relationships between people and ...
For projections from one region of the nervous system to another, see neural pathway. A neural circuit is a population of neurons interconnected by synapses to carry out a specific function when activated. [ 1 ] Multiple neural circuits interconnect with one another to form large scale brain networks. [ 2 ]
Theorists differ in how they relate consciousness to electromagnetism. Electromagnetic field theories (or "EM field theories") of consciousness propose that consciousness results when a brain produces an electromagnetic field with specific characteristics. Susan Pockett [ 1 ][ 2 ] and Johnjoe McFadden [ 3 ] have proposed EM field theories ...
Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, [ 1 ] with a specific focus on the neural connections in the brain which are involved in mental processes. It addresses the questions of how cognitive activities are affected or controlled by neural ...
Neuroplasticity, also known as neural plasticity or brain plasticity, is the ability of neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. [ 1 ]
