[The plasticity of systemic brain mechanisms]

Area of Science:

• Neuroscience
• Behavioral Biology
• Molecular Biology

Background:

• Systemic behavioral acts are organized by dominant motivation and reinforcement mechanisms.
• Understanding neural plasticity is crucial for explaining behavioral regulation.

Purpose of the Study:

• To investigate the plasticity mechanisms of dominant motivation and reinforcement in behavioral organization.
• To elucidate the role of neuromediators, neuropeptides, and oligopeptides in neural plasticity and behavioral control.

Main Methods:

• Analysis of neuronal properties, including sensitivity to neuromediators and neuropeptides.
• Investigation of genetic apparatus modification in neurons.
• Examination of chemical integration in limbic-reticular neurons under emotional stress.

Main Results:

• Dominant motivation alters neuronal properties and sensitivity to neuromediators/neuropeptides.
• Reinforcement modifies neurons involved in dominant motivation, impacting genetic expression and information molecule production.
• Emotional stress reveals neuronal plasticity, involving limbic-reticular system reorganization mediated by oligopeptides.
• Oligopeptides demonstrate a capacity to compensate for damaged limbic-reticular structures.

Conclusions:

• Neural plasticity in dominant motivation and reinforcement is a dynamic process involving genetic and molecular changes.
• Oligopeptides play a critical role in emotional stress responses and functional compensation within the limbic-reticular system.
