Coordination Number and Geometry02:57

Coordination Number and Geometry

19.1K
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.

Coordination Compounds and Nomenclature

26.9K
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...

Lattice Centering and Coordination Number

11.7K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

The Auditory Ossicles

3.2K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Equations of Motion: Rectangular Coordinates and Cylindrical Coordinates

782
Understanding the motion of particles is a fundamental aspect of classical mechanics, and the choice of the coordinate system plays a pivotal role in unraveling the complexities of their dynamics.
When a particle moves relative to an inertial frame, the equations of motion can be expressed using rectangular components. If the motion is confined to the x-y plane, the equations having the x and y coordinates only can be used to simplify the mathematical representation.
However, when particles...

Coordinate Plane01:21

Coordinate Plane

373
The Cartesian coordinate plane is a fundamental structure in mathematics that enables the visualization of relationships between numerical values in two dimensions. It is formed by two intersecting number lines: a horizontal x-axis and a vertical y-axis. These axes meet at the origin, the point where both values are zero. Their intersection divides the plane into four quadrants labeled in a counterclockwise direction starting from the upper right.An ordered pair of numbers represents every...

Area of Science:

  • Neuroscience
  • Auditory Neuroscience
  • Systems Neuroscience

Background:

  • Synchronous neuronal activity is crucial for cortical information processing.
  • Primary auditory cortex (AI) research often overlooks coordinated neuronal activity, focusing on independent neuron filters.
  • Understanding coordinated activity within AI cortical columns is vital for auditory information processing.

Purpose of the Study:

  • To investigate how coordinated neuronal activity is expressed within AI cortical columns.
  • To determine if coordinated neuronal ensembles (cNEs) enhance auditory information processing.
  • To explore the functional significance of cNEs in AI.

Main Methods:

  • Recorded population activity from AI cortical columns in anesthetized rats.
  • Applied dimensionality reduction techniques to identify coordinated neuronal ensembles (cNEs).
  • Analyzed both spontaneous and evoked neuronal activity.

Main Results:

  • Identified multiple coordinated neuronal ensembles (cNEs) with reliable synchronous activity.
  • Demonstrated that cNEs reflect local network configurations with enhanced information encoding.
  • Showed that cNEs' properties cannot be solely explained by stimulus-driven synchronization.
  • Found similar cNEs in both spontaneous and evoked activity.

Conclusions:

  • Coordinated neuronal ensembles (cNEs) are stable functional constructs within AI cortical columns.
  • cNEs exhibit enhanced information encoding properties beyond stimulus-driven synchronization.
  • These columnar cNEs may represent fundamental units of information processing in the primary auditory cortex (AI).
