[THE BASOLATERAL NUCLEUS IN THE SYSTEM OF REPRODUCTIVE CENTERS OF THE AMYGDALA]
Morfologiia (Saint Petersburg, Russia)
|November 26, 2015
Summary
The basolateral amygdala exhibits sexual dimorphism, influencing reproductive behaviors and gonadotropin secretion. This brain region integrates sensory and pheromone information, impacting sex-specific emotional and stress responses.
Area of Science:
- Neuroscience
- Endocrinology
- Behavioral Biology
Context:
- The basolateral nucleus of the amygdala is a key brain region involved in processing sensory and olfactory information.
- Sexual dimorphism in brain structures is increasingly recognized for its role in sex-specific behaviors and physiological responses.
Purpose:
- To review and systematize current literature on the basolateral nucleus of the amygdala as a zone of sexual dimorphism (SDZ).
- To elucidate the relationship between the basolateral nucleus and other amygdalar reproductive centers.
- To understand the role of this SDZ in sexual behavior, gonadotropin secretion, and sex-dependent behavioral manifestations.
Summary:
- The basolateral nucleus, a phylogenetically newer amygdalar structure, receives significant pheromone and olfactory input via the older corticomedial division.
- It integrates this information with sensory signals from the thalamus and cortex.
- Together with SDZs in the corticomedial division, it organizes sexual behavior and regulates gonadotropin secretion.
Impact:
- Sexual dimorphism in the basolateral nucleus contributes to sex-specific emotional processing and memory formation.
- These dimorphisms influence behavioral manifestations, particularly in stress reactions.
- Understanding these mechanisms is crucial for comprehending sex differences in behavior and neuroendocrinology.

01:15Functional Brain Systems: Limbic System
9.0K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

5.2K
The hypothalamus is a small yet highly complex and essential brain region that plays a crucial role in regulating various bodily functions. Anatomically, it is located at the base of the brain, just above the brainstem and below the thalamus, forming part of the limbic system.
The hypothalamus interacts with other brain regions, including the pituitary gland, through a direct physical connection called the hypothalamic-pituitary axis. The hypothalamus receives somatic and visceral inputs and...

The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...

01:16Role of Amygdala in Memory
1.6K
The amygdala is a small, almond-shaped structure responsible for processing and storing memories, particularly those linked to emotions like fear and stress. It plays an essential role in the brain's response to emotionally significant events and often enhances memory formation by triggering stress hormone release. The amygdala is vital for encoding and retrieving memories associated with fear or stress, a process that is adaptive by helping organisms avoid dangerous situations.

The medulla oblongata is a crucial part of the brainstem responsible for controlling various autonomic and involuntary functions. It contains several nuclei, including the olivary, cuneate, gracile, and solitary nuclei.
Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...

01:17The Pituitary Gland
15.2K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.
