Neurulation

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...

Organization of the Nervous System

Organization of the Nervous System

The nervous system is one of the most complex systems in our body. It is organized into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS, comprising the brain and spinal cord, houses billions of neurons. The brain is housed in the skull, while the spinal cord is linked to the brain through the foramen magnum of the occipital bone and is surrounded by the protective structure of the vertebral column. It is responsible for processing various...

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Nervous System

Nervous System

The nervous system coordinates body functions through its complex network of nerve cells, enabling sensation and movement. It is divided into two primary parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and the spinal cord. The brain acts as the body's control center, processing sensory information and coordinating responses. The spinal cord functions as a major signaling pathway for the brain and the rest of the body.

Functional Divisions of the Nervous System

Functional Divisions of the Nervous System

The nervous system, responsible for sensing, integrating, and responding to various stimuli, is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS has two functional divisions: the sensory or afferent division and the motor or efferent division.
The sensory division transmits information from sensory receptors in the body to the CNS. It provides the CNS with knowledge about somatic senses (such as tactile, thermal, pain, and proprioceptive sensations)...

Organization of the Brain

Organization of the Brain

The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Background:

Sensory systems in the nervous system often exhibit topographic mapping, where neighboring neurons maintain spatial relationships.
This topographic organization is clearly observed in the visual system, with retinal neurons projecting to adjacent neurons in target areas like the superior colliculus.

Purpose of the Study:

To discuss the developmental mechanisms underlying the formation of topographic maps.
To emphasize the role of theoretical models in elucidating these mechanisms.
To address new challenges for theoretical models posed by recent experimental advances.

Main Methods:

Review of theoretical models of topographic map formation.
Discussion of experimental findings on guidance molecules.
Analysis of spontaneous neural activity patterns.

Main Results:

Theoretical models are essential for understanding topographic map development.
Guidance molecules and spontaneous neural activity are key factors.
New experimental data present challenges and opportunities for theoretical frameworks.

Conclusions:

Understanding instructional cues in spontaneous activity and the interaction between activity and guidance molecules are critical research questions.
Comparing visual and olfactory map development reveals differing roles for neural activity.
Theoretical modeling remains vital for advancing our comprehension of neural map formation.
