An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and non-human anatomy, three principal planes are used: The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture. It divides the body ...
A muscle synergy is a group of synergistic muscles and agonists that work together to perform a motor task. A muscle synergy is composed of agonist and synergistic muscles. An agonist muscle is a muscle that contracts individually, and it can cause a cascade of motion in neighboring muscles.
A decussation (from Latin decussis 'ten', written as a capital X) refers to nerve fibers that cross the sagittal plane from one side of the central nervous system to the other, and connect different brain regions. There are two kinds: Type 1 crosses the sagittal plane in the same brain
A brain atlas is composed of serial sections along different anatomical planes of the healthy or diseased developing or adult animal or human brain where each relevant brain structure is assigned a number of coordinates to define its outline or volume.
He wrote Cerebri Anatome (Latin: Anatomy of the brain) [c] in 1664, followed by Cerebral Pathology in 1667. In these he described the structure of the cerebellum, the ventricles, the cerebral hemispheres, the brainstem, and the cranial nerves, studied its blood supply; and proposed functions associated with different areas of the brain.

In anatomy in general and neuroanatomy in particular, several sets of topographic terms are used to denote orientation and location, which are generally referred to the body or brain axis (see Anatomical terms of location). The axis of the CNS is often wrongly assumed to be more or less straight, but it actually shows always two ventral ...

Map of the body in the human brain. The clearest example of the coordination of muscles into complex movement in the motor cortex comes from the work of Graziano and colleagues on the monkey brain. [11] [26] They used electrical stimulation on a behavioral time scale, such as for half a second instead of the more typical hundredth of a second ...
