Summary
Brain system organization refines during development, with maturational processes and cognitive abilities correlating with distinct brain system border development. This research clarifies how brain networks evolve with age and cognitive function.
Area of Science:
- Neuroscience
- Developmental Neuroscience
- Cognitive Neuroscience
Background:
- Brain system organization undergoes significant changes during development.
- Understanding the evolution of brain networks is crucial for comprehending cognitive maturation.
Purpose of the Study:
- To investigate how brain system organization evolves during human development.
- To determine the relationship between maturational processes, cognitive ability, and brain system refinement.
Main Methods:
- Utilized large-scale, high-precision functional Magnetic Resonance Imaging (fMRI) data.
- Analyzed individual differences in the development of borders between brain systems.
Main Results:
- Maturational processes correlate with individual differences in brain system organization.
- Cognitive abilities track the refinement of borders between brain systems.
- Developmental changes in brain network boundaries are linked to cognitive development.
Conclusions:
- Brain system organization evolves through the refinement of inter-system borders during development.
- Maturational status and cognitive ability are key factors influencing this developmental trajectory.
- This study provides insights into the neural basis of cognitive development and individual differences.

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...

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...

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...

01:29Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

01:18Anatomy of the Brain: Ventricles
7.3K
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.

01:22Lobes of the Cerebrum
3.5K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....
