Document Summary
Functional near-infrared spectroscopy: non-invasive technique that gathers light transmitted through cortical tissue to image blood-oxygen consumption; form of optical tomography. Neuropsychology: study of the relations between brain function and behaviour. Behavioural neuroscience: study of the biological bases of behaviour. Stereotaxic apparatus: surgical instrument that permits the researcher to target a specific part of the brain. Deep-brain stimulation (dbs): neurosurgery in which electrodes implanted in the brain stimulate a targeted area with a low-voltage electrical current to facilitate behaviour. Transcranial magnetic stimulation (tms): procedure in which a magnetic coil is placed over the skull to stimulate the underlying brain; used either to induce behaviour or to disrupt ongoing behaviour. Optogenetics: transgenic technique that combines genetics and light to control targeted cells in living tissue. Electrocorticography: graded potentials recorded with electrodes placed directly on the brain"s surface. Alpha rhythm: regular wave pattern in an electroencephalogram; found in most people when they are relaxed with closed eyes.
