Overview of Valence Bond Theory

Valence Bond Theory

Valence Bond Theory

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Valence Bond Theory and Hybridized Orbitals

Valence Bond Theory and Hybridized Orbitals

According to valence bond theory, a covalent bond results when: (1) an orbital on one atom overlaps an orbital on a second atom, and (2) the single electrons in each orbital combine to form an electron pair. The strength of a covalent bond depends on the extent of overlap of the orbitals involved. Maximum overlap is possible when the orbitals overlap on a direct line between the two nuclei.
A σ bond (single bond in a Lewis structure) is a covalent bond in which the electron density is...

Second-Order Circuits

Second-Order Circuits

Integrating two fundamental energy storage elements in electrical circuits results in second-order circuits, encompassing RLC circuits and circuits with dual capacitors or inductors (RC and RL circuits). Second-order circuits are identified by second-order differential equations that link input and output signals.
Input signals typically originate from voltage or current sources, with the output often representing voltage across the capacitor and/or current through the inductor. For example, in...

First-Order Circuits

First-Order Circuits

First-order electrical circuits, which comprise resistors and a single energy storage element - either a capacitor or an inductor, are fundamental to many electronic systems. These circuits are governed by a first-order differential equation that describes the relationship between input and output signals.
One common example of a first-order circuit is the RC (resistor-capacitor) circuit. These circuits are used in relaxation oscillators such as neon lamp oscillator circuits. When voltage is...

Background:

Emotional valence, the subjective experience of good or bad, is fundamental for survival.
Understanding the neural basis of valence processing bridges psychology and neuroscience.
The brain employs diverse strategies for valence evaluation at multiple levels.

Purpose of the Study:

To review circuit motifs underlying emotional valence processing in the brain.
To connect psychological concepts of valence with neurobiological implementations.
To highlight key neural strategies for evaluating stimuli as good or bad.

Main Methods:

Review of neuroscientific studies on emotional valence.
Identification of recurring circuit motifs in valence processing.
Analysis of neural substrates and their functional dynamics.

Main Results:

Identified four key circuit motifs: Labeled Lines, Divergent Paths, Opposing Components, and Neuromodulatory Gain.
These motifs represent implementational systems for valence processing.
Neural substrates for valence are dynamic, context-dependent, and adaptable.

Conclusions:

The brain utilizes specific circuit motifs for processing emotional valence.
Valence processing is not static but changes over time and with context.
Understanding these neural dynamics is key to comprehending survival-related behaviors.
