10-20 System A method to position surface electrodes on the human scalp for
EEG recordings
2D two-dimensional
3D three-dimensional
Abductor digiti minimi (ADM) Muscle at the little finger
Abductor hallucis muscle (AHM) Muscle at the foot's inner border
Action Potential Short-lasting pulse in a cell which leads to a rapid fall or rise of
the electrical membrane potential. Action Potentials are the basis for neuronal
cell-to-cell communication
Analog-digital converter (ADC) An electrical component which converts analog
signals, e.g. voltage signals, into digital numbers, e.g. bits
Blood oxygenation level dependent (BOLD) The change in the concentrate of
oxygen in the blood is used as a measure for brain activity during functional
MRI
Boxplot Diagram to visualize the distribution of data. It consists of a box that
expresses the 25th and 75th percentile. The median is shown as a horizontal line
inside this box and the whiskers denote the minimum and maximum, respec-
tively. Outliers are marked separately
Computed Tomography (CT) Volumetric imaging method based on multiple
X-ray images
Computer-Aided Design (CAD) Construction with help of software tools
Degrees of Freedom (DOF) Number of independent parameters defining the
rotation and displacement
Denavit-Hartenberg (DH) Specific convention for kinematic chains, mainly
used in robot manipulators
