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...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

The Representativeness Heuristic

The Representativeness Heuristic

The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Neuronal Communication

Neuronal Communication

Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...

Graphical Representation of Inequalities

Graphical Representation of Inequalities

The graph of the equation where y equals x squared forms a curve known as a parabola. This curve acts as a boundary in the coordinate plane, dividing it into distinct regions based on the relative position of points.When the equality sign in the equation is replaced with an inequality—such as greater than, less than, greater than or equal to, or less than or equal to—the graphical representation changes from a single curve into a broader shaded area that signifies the set of all points...

Background:

Understanding the neural basis of decision-making is crucial for economics and marketing.
Previous research explored brain activity related to value and preference, but direct prediction of product choice from specific neural signals remained challenging.
The ventromedial prefrontal cortex is implicated in value-based decision-making.

Purpose of the Study:

To investigate if human product preference can be predicted from brain activity.
To determine if changes in oxygenated hemoglobin concentration in the ventromedial prefrontal cortex correlate with product selection.
To assess the utility of functional near-infrared spectroscopy (fNIRS) for predicting preferences despite its limited depth.

Main Methods:

A product selection task was employed to observe participant choices.
Functional near-infrared spectroscopy (fNIRS) was used to measure changes in oxygenated hemoglobin concentration in the ventromedial prefrontal cortex.
A Bayesian three-layer perceptron model was utilized for predictive analysis of product preference based on neural data.

Main Results:

The study successfully predicted human product preference to an extent using neural data.
Changes in oxygenated hemoglobin concentration in the ventromedial prefrontal cortex were found to be significant predictors of choice.
Functional near-infrared spectroscopy (fNIRS) demonstrated its capability to yield predictive insights into preferences, even with shallow brain measurements.

Conclusions:

Neural signals, specifically oxygenated hemoglobin changes in the ventromedial prefrontal cortex, can predict product preferences.
Functional near-infrared spectroscopy (fNIRS) is a viable tool for neuroscientific investigations into economic and marketing-related behaviors.
This research provides a neuroscientific foundation for understanding utility in economic and marketing theories, with practical implications.
