要旨

Objective:

Preterm birth is associated with an increased risk of functional brain network alterations, which may contribute to long-term motor and neurocognitive deficits. However, the underlying neural mechanisms remain incompletely understood. This study aimed to investigate functional brain activity changes in preterm infants and their correlation with early neurobehavioral development.

Methods:

Fifteen preterm infants and 15 full-term infants underwent scanning using a 3.0T Philips MRI scanner. Three resting-state functional magnetic resonance imaging (rs-fMRI) data-driven approaches, amplitude of low-frequency fluctuations (ALFF), regional homogeneity (ReHo), and seed-based functional connectivity (FC) were used to comprehensively evaluate functional brain alterations in preterm infants at term-equivalent age (TEA). Correlations between Neonatal Behavioral Neurological Assessment (NBNA) scores and FC values of abnormally connected brain regions were further analyzed in preterm infants at TEA.

Results:

Compared with full-term infants, preterm infants exhibited significantly higher ALFF and ReHo values in the left precuneus. Using the left precuneus as a seed region for FC analysis, preterm infants showed reduced FC with the left Rolandic operculum, right putamen, and left hippocampus. Additionally, FC values between the left precuneus and left Rolandic operculum, as well as between the left precuneus and right putamen, were positively correlated with NBNA scores in preterm infants.

Conclusions:

Preterm infants may present early functional connectivity impairments of the left precuneus, which may be a potential neural correlate of neurobehavioral abnormalities. These findings provide insights into the neurodevelopmental mechanisms underlying preterm birth-related deficits and may inform early clinical assessment strategies.

Functions of Connective Tissues

Functions of Connective Tissues

Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Association Areas of the Cortex

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Dietary Connections

Dietary Connections

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Drug Dosing: Infants and Children

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Introduction to Connective Tissues

Introduction to Connective Tissues

Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts,...
