Cerebrum: Anatomical Overview II

Cerebrum: Anatomical Overview II

Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

Neuron Structure

Neuron Structure

Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.
Structure and Function of Neurons
The neuronal cell body—the soma— houses the nucleus and organelles vital to...

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Molecular Biology
Neuroscience
Genetics

Background:

Circular RNAs (circRNAs) are abundant, conserved non-coding RNAs formed by exon circularization.
Thousands of circRNAs have been identified across various organisms and cell types.
Emerging evidence highlights significant roles for circRNAs in the central nervous system.

Purpose of the Study:

To review current advancements in circRNA research within the brain.
To propose hypotheses regarding circRNA functions in neuronal plasticity and function.
To explore the potential involvement of circRNAs in neurodegenerative processes.

Main Methods:

Literature review of studies on circRNAs in neuronal tissues.
Analysis of data on circRNA expression dynamics during neuronal differentiation and activity.
Synthesis of findings related to circRNA enrichment in synapses and aging.

Main Results:

Neuronal-expressed RNAs are processed into highly enriched circRNAs in various species.
CircRNA levels are dynamically regulated in neurons, correlating with differentiation, electrical activity, and age.
Many circRNAs are found to be enriched in synapses, suggesting roles in neuronal communication.

Conclusions:

CircRNAs play critical roles in synaptic plasticity and overall neuronal function.
Dysregulation of circRNAs may be implicated in the initiation and progression of neurodegenerative diseases.
Further research into circRNA mechanisms is warranted for understanding brain health and disease.
