Summary
Direct human brain connectional neuroanatomy is limited, despite common belief. A systematic homological approach, using non-human models, is key to understanding human structural and connectional neuroanatomy more precisely.
Area of Science:
- Neuroscience
- Human Neuroanatomy
Background:
- Human brain structure is extensively studied, but direct connectional neuroanatomy remains limited.
- A misperception exists that human connectional neuroanatomy is well-established.
Purpose of the Study:
- To clarify the current state of knowledge regarding direct human structural and connectional neuroanatomy.
- To advocate for a systematic homological approach for a more precise understanding.
Main Methods:
- Reviewing existing knowledge on human neuroanatomical connections.
- Analyzing information derived from non-human experimental models.
- Utilizing homological comparisons, particularly with non-human primates.
Main Results:
- Direct information on human brain connections (origin to termination) is scarce.
- Current understanding relies heavily on data from non-human models and homological comparisons.
- Advancing techniques for human structural connectivity are still limited.
Conclusions:
- A precise understanding of human connectional neuroanatomy is not yet achieved.
- Systematic application of homological approaches is proposed for future advancements.
- Further research using comparative methods is essential for validating human neuroanatomy.

4.0K
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...

4.1K
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...

01:22Neurons as Communicators of the Brain
2.7K
Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

01:30Organization of the Brain
2.1K
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...

4.4K
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...
