Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on ...
Mental rotation is the ability to rotate mental representations of two-dimensional and three-dimensional objects as it is related to the visual representation of such rotation within the human mind. [1] There is a relationship between areas of the brain associated with perception and mental rotation.
One common diagram of the somatotopic map is the cortical homunculus. This illustration is a fairly accurate representation of how much cortical area represents each body part or region. It also maps what part of the cortex represents each region of the body.
The brain-to-body mass ratio was however found to be an excellent predictor of variation in problem solving abilities among carnivoran mammals. [20] In humans, the brain to body weight ratio can vary greatly from person to person; it would be much higher in an underweight person than an overweight person, and higher in infants than adults.
One version of the proportions used in modern figure drawing is: [4] An average person is generally 7-and-a-half heads tall (including the head). An ideal figure, used when aiming for an impression of nobility or grace, is drawn at 8 heads tall. A heroic figure, used in the depiction of gods and superheroes, is eight-and-a-half heads tall. Most ...
The blood in the deep part of the brain drains, through a venous plexus into the cavernous sinus at the front, and the superior and inferior petrosal sinuses at the sides, and the inferior sagittal sinus at the back. [61] Blood drains from the outer brain into the large superior sagittal sinus, which rests in the midline on top of the brain.

In human neuroanatomy, brain asymmetry can refer to at least two quite distinct findings: Neuroanatomical differences between the left and right sides of the brain; Lateralized functional differences: lateralization of brain function; A stereotypical image of brain lateralisation - demonstrated to be false in neuroscientific research.
