Thalamocortical bundles

Introduction

The Thalamorkory fascicles (literally "cortex-connected bundles" or "papulocornal connection") are specialized connecting structures between individual segments and bodies of the thalamus and the cerebral cortex. These bundles provide the integration of information received from different sensory channels and form the basis for information processing in different areas of the cerebral cortex. The thalamic-cortical fascicles play an important role in the processing of sensory stimuli and are involved in functions such as visual perception, motor function, and attention. In this article we will look at the mechanism of operation, the anatomical features of the structure and the significance of these connections in the functioning of the human brain.

Anatomy

The cerebral cortex is a layer of nerve cells located in the head above the parietal lobe, along which the Thalamurcoria bundles run. The general path is accompanied by a connection between the lower two areas of the brain, where the nerve centers are located that control the perception and processing of most types of information, as well as its transmission between different parts of the brain (Fig. 2).

**Properties of Thalamour-Corcular connections**

Thalamurcoliteral bundles are specialized formations of neuroglia, small in size and with round terminal balls with a height of 400-800 microns. Each bundle consists of a thin, long axial cylinder and contains nerve cells in the form of a dense ball. The collateral collateral connection with its accompanying connective filament is an important component that determines the organization of connections in various brain regions (Figure 3).

Thalamocortical bundles: an important connection between the thalamus and cortex

Thalamocortical fascicles, also known as thalamocortical tracts, are neural connections that are established between the thalamus and the cerebral cortex. These bundles play an important role in transmitting information between different parts of the brain and provide communication between sensory systems and the areas of the cortex responsible for processing and perceiving this information.

The thalamus is a key structural component of the diencephalus, located in the center of the brain. It acts as a relay and filter for sensory information coming from peripheral receptors (such as vision, hearing, touch) and sends it to the appropriate areas of the cerebral cortex for further processing.

Thalamocortical bundles consist of fiber connections that pass through the white matter of the brain and connect the thalamus with the corresponding areas of the cortex. They consist of neuron axons that form long bundles and transmit electrical impulses between these two brain structures.

The functional role of the thalamocortical bundles is to transmit information about sensory inputs from the thalamus to the corresponding areas of the cerebral cortex. For example, thalamocortical bundles related to the visual system transmit information about visual stimuli from the thalamus to the cortical areas responsible for processing visual signals. Likewise, thalamocortical fascicles, associated with other sensory systems such as hearing or touch, ensure the transfer of information from the thalamus to the corresponding areas of the cortex for further processing and perception.

Thalamocortical bundles also play an important role in maintaining consciousness and awareness. They help transmit information about the outside world to the cerebral cortex, which allows us to perceive and respond to our environment. Disturbances in the functioning of the thalamocortical bundles can lead to various neurological disorders, such as decreased perception, loss of consciousness or impaired attention.

In conclusion, the thalamocortical fasciculi are important connections between the thalamus and the cerebral cortex. They mediate sensory information and play an important role in processing and perceiving environmental stimuli. Understanding and studying these bundles will help us gain deep insights into brain functioning and help develop treatments for neurological disorders associated with these bundles. Further research in this area could shed light on the complex mechanisms of information processing in the brain and lead to new technologies and approaches in neuroscience and neuroscience.

Chapter VII. Musculocutaneous, innervated by the dorsal branches of the spinal nerves and bundles of radicular nerves.

These bundles include: two ascending motor and eight descending projection nerve bundles. Among them are five pairs located on one side of the spinal cord - the anterior commissure, the posterior commissure and two posterior cords (superior and inferior). (Table 35.)

Ascending motor fibers reach the thoracic and cervical regions of the brain. Descending fibrous connections of the spinal and medulla oblongata reach the stellate ganglion, and then go to the skin and muscles of the upper limb and trunk. Fibers from the lateral horns of the thoracic spinal cord (thoracic segments Th6-L2) pass through the anterior commissure. The direction of the fibers is radial and lateral. For the anterior and posterior horns of the left and right thoracic and lateral segments L4-S1 there is a common terminal plate, which is connected by the ventral part of the anterior commissure.
