Summary
New research highlights the importance of previously overlooked folds in the cerebral cortex. These cortical folds are key to understanding individual differences in brain structure.
Area of Science:
- Neuroscience
- Human Anatomy
Background:
- The cerebral cortex, the brain's outer layer, exhibits complex folding patterns.
- Individual variations in cortical folding are significant but often understudied.
Purpose of the Study:
- To investigate the role of previously underappreciated folds in the cerebral cortex.
- To explore how these folds contribute to structural variability across individuals.
Main Methods:
- Utilizing advanced neuroimaging techniques.
- Analyzing detailed anatomical data of the cerebral cortex.
Main Results:
- Identified specific underappreciated cortical folds with significant anatomical variation.
- Demonstrated a correlation between these folds and overall cerebral cortex structure differences.
Conclusions:
- Previously overlooked cortical folds are crucial for understanding individual brain structure.
- These findings open new avenues for studying neurodevelopmental variations and brain disorders.

01:30Organization of the Brain
3.9K
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...

13.5K
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...

01:13Functional Brain Systems: Reticular Formation
6.3K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

6.9K
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...

01:18Anatomy of the Brain: Ventricles
11.8K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

01:11Cerebrum: Anatomical Overview II
6.1K
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...
