For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

The present work provides a comprehensive set of guidelines for manually tracing the medial temporal lobe (MTL) structures. This protocol can be applied to research involving structural and/or combined structural-functional magnetic resonance imaging (MRI) investigations of the MTL, in both healthy and clinical groups.

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Balance and Coordination Testing

Balance and coordination are critical components involved in the control of movement. Many sensory receptors and neural processing units are required to help individuals maintain balance while performing various activities. Deficits in balance and coordination occur in patients suffering from movement disorders or due to aging. Therefore, scientists are trying to understand the pathophysiology behind these conditions. One way to do that is by using rodent models and testing them on behavioral...
FAQs
The medial-lateral axis supplies one spatial dimension within a larger coordinate framework. Interpreting it together with anterior-posterior and dorsal-ventral positions allows researchers to describe a neural structure as a specific three-dimensional location rather than as an isolated direction. This combined representation supports consistent localization across brain and spinal cord studies.
The midsagittal plane provides the reference from which medial or lateral position is judged. If that reference is applied inaccurately, the reported location of a structure can be misplaced relative to the brain's central axis. Careful designation therefore improves comparisons among anatomical findings and supports more reliable relationships between location, neural function, and behavior.
Each coordinate describes a different directional relationship. Medial-lateral position identifies location relative to the body's midline, whereas anterior-posterior and dorsal-ventral coordinates describe the other spatial dimensions used in neural anatomy. Separating these axes prevents a position along one direction from being confused with another and makes brain and spinal cord localization more precise.
Their value comes from connecting anatomical position with experimental interpretation. A structure's medial or lateral placement can be compared with its measured activity, neighboring anatomy, or associated behavior when the location is recorded accurately. This spatial information helps researchers analyze how structural organization relates to neural function without treating location as an isolated observation.
In brain atlases and magnetic resonance images, these coordinates help identify where a structure lies relative to the midsagittal reference and to the other spatial axes. Researchers can use that shared framework to localize findings, compare anatomical observations, and relate image-based structure to results from brain-mapping studies.
They provide a spatial reference for planning or documenting where an electrode or injection is placed within neural tissue. Combining medial-lateral information with the other coordinate axes gives the intended target a three-dimensional location. Accurate recording of that position helps researchers compare the intervention or measurement with the neural structure and its function.
A consistent medial-lateral designation allows findings from different studies to be compared according to the locations examined. When researchers also report the anterior-posterior and dorsal-ventral dimensions, they can distinguish whether apparently different results reflect different neural sites. This supports brain mapping and interpretation of how anatomical position may relate to behavior.
Spatial coordinates make it possible to examine whether observations associated with behavior arise from the same or different anatomical regions. Medial-lateral placement contributes one part of that comparison, while the remaining axes establish the full location. Accurate localization therefore strengthens analyses connecting structural findings, neural measurements, and behavioral outcomes.
