Paleothalamus (Palaeothalamus)

Palaeothalamus is the anterior and central parts of the thalamus, which, in accordance with the evolution of its development, are older than the lateral part, the neothalamus, which is well developed in monkeys and humans.

The thalamus is a paired structure of the brain located between the body of the brain and the cerebral hemispheres. It acts as a relay of sensory information entering the cerebral cortex.

From an evolutionary point of view, the thalamus consists of two parts:

1. Paleothalamus (ancient thalamus) is a more primitive part, including the anterior and medial nuclei. It developed earlier in phylogenesis and is involved in the regulation of vegetative functions.

2. The neothalamus (new thalamus) is a more advanced lateral part that has evolved extensively in mammals. It provides connection between the cerebral cortex and sensory systems.

Thus, the paleothalamus is an evolutionarily older part of the thalamus compared to the neothalamus, which became more developed at later stages of evolution in primates, including humans.

Palaeothalamus: the oldest part of the thalamus

The thalamus is a region of the brain that plays an important role in regulating many functions such as sleep, perception, attention, memory and movement. It consists of several parts, including the front, center and side parts. The paleothalamus is one of the oldest parts of the thalamus, which is located in the anterior and central part.

According to evolutionary development, the paleothalamus is an older part of the thalamus compared to the lateral part called the neothalamus. The neothalamus is well developed in monkeys and humans and plays an important role in the regulation of higher mental functions such as thinking, speech and learning.

The paleothalamus, in turn, plays an important role in the regulation of simpler functions, such as responses to pain and other external stimuli, as well as the regulation of motor activity. It is also involved in regulating mood and emotions, similar to the limbic system.

The study of the paleothalamus and its functions is an important area in neuroscience, since understanding its role can help in the treatment of various diseases associated with impaired brain function, such as Alzheimer's disease, Parkinson's disease and others.

In conclusion, paleothalamus is one of the key parts of the thalamus and plays an important role in regulating various functions of the body. Its study is important for understanding the functioning of the brain and developing new methods for treating diseases associated with impaired brain function.

The paleothalamus is the anterior and central part of the thalamus. It is older than the lateral section, which is called the neothalamus. The neothalamus is well developed in monkeys and humans. The paleothalamus, like the neothalamus, plays an important role in processing information coming from the outside world through sensory systems. However, the paleothalamus has a more complex structure and functionality than the neothalamus.

The paleothalamus consists of several nuclei that are responsible for processing information about vision, hearing, smell and touch. It is also involved in the regulation of sleep and wakefulness, as well as in the formation of emotional reactions to external stimuli.

One of the features of the paleothalamus is its ability to synchronize work with other parts of the brain. This allows it to efficiently process information and coordinate the actions of different parts of the body.

In addition, the paleothalamus plays an important role in the development of memory and learning. It is involved in the formation of long-term memories and their retention in memory.

Thus, the paleothalamus is an important part of the brain that plays a key role in processing and transmitting information. Its development went in parallel with the development of the neothalamus, but has a more complex and diverse structure and functions.
