Systemic Quantization of Mental Activity

For medical students2 min readUpdated 2026-10-10

Human mental activity is neither chaotic nor a continuous stream. It is strictly discrete and divided into individual functional segments known as systemic quanta (sistemokvanty), each directed toward satisfying a specific dominant need.

Boundaries of a quantumDefined by dominant motivation and final reinforcement
Criterion of successSatisfaction of the organism's leading mental need
MismatchTriggers negative emotions and initiates the search for new solutions
Material basisBesides neurons, DNA and RNA molecules play a key role

Principle of Systemic Quantum Organization

The foundation for forming any systemic quantum is the principle of self-regulation. The organism constantly assesses how intermediate and final results of its actions bring it closer to the goal.

The key mechanism of this evaluation is feedback (reverse afferentation)—a stream of signals from receptors regarding achieved parameters. All information entering from the external environment, as well as each step of mental activity, passes through a specific filter: the prism of satisfying the dominant need. Motivation and reinforcement together shape the informational architecture of the entire process.

Outcomes of Activity

The outcome of any systemic quantum depends on whether actual results match expected outcomes. This evaluation occurs in a specialized neural apparatus: the action result acceptor (akseptor rezultata deystviya, ARD).

  1. Successful Completion (Match)

If the parameters of the achieved result fully correspond to the properties of the action result acceptor, the initial need is satisfied. The subject experiences a positive emotion, the current systemic quantum concludes, and a new need forms in its place, triggering the next cycle.

  1. Unsuccessful Completion (Mismatch)

If actual results do not match the matrix of the action result acceptor, a mismatch occurs. This is accompanied by negative emotions of varying intensity and triggers exploratory behavior. The organism must restructure afferent synthesis, make a new decision, and adjust the acceptor itself. Mental activity is not interrupted, but rather redirected toward achieving the modified goal.

Types of Quantization

In humans, the construction of systemic quanta relies on genetic mechanisms, past experience (learning), and specific verbal factors (instructions and self-instructions). Three main types of quantization are distinguished:

Cerebral Mechanisms and Process Transformation

The central architecture of functional systems represents the dynamics of informational processes within brain structures. Notably, information transmission at all stages (from excitation to the feedback influence of the action result acceptor) proceeds without losing the initial informational meaning of the need.

During mental activity, a continuous mutual transition occurs between the material and the ideal (informational):

Mnemonic

To remember the three types of quantization, recall H-S-M: Hierarchical, Sequential, Mixed.

Frequently asked questions

What specific stages (components) are included in the stage of afferent synthesis?

The stage of afferent synthesis integrates several components:

  • Motivation—dominant motivational arousal.
  • Situational afferentation—environmental influences continuously received via exteroceptors.
  • Memory—utilization of genetic and individually acquired memory.
  • Trigger stimulus—a releasing component that unlocks the established pre-trigger integration (e.g., conditioned stimuli or time factors).
What happens when there is a mismatch between result parameters and the action result acceptor?

A negative emotion arises and exploratory behavior is triggered. The subject reorganizes afferent synthesis and makes a new decision.

On what basis are systemic quanta formed specifically in humans?

Unlike in animals, human systemic quanta are based not only on genetics and prior learning, but also on verbal instructions and self-instructions.
