Resumen
Los niños con Trastorno del Espectro Autista (TEA) muestran conectividad cerebral alterada, topología de red alterada y dinámicas temporales anormales, lo que sugiere nuevos biomarcadores para la neurofisiología.
Área de la Ciencia:
- Neurociencia
- Psicología del Desarrollo
- Biofísica
Sus antecedentes:
- El Trastorno del Espectro Autista (TEA) es un trastorno del neurodesarrollo con causas desconocidas.
- La conectividad alterada de la red funcional cerebral está relacionada con las características clínicas del TEA.
- Se requieren más investigaciones sobre los patrones y mecanismos específicos de estas anomalías.
Objetivo del estudio:
- Investigar la topología de red y las transiciones dinámicas en el Trastorno del Espectro Autista (TEA).
- Analizar redes funcionales estáticas y dinámicas en todas las bandas de frecuencia.
- Explorar las interacciones entre frecuencias en niños con TEA.
Principales métodos:
- Se reclutaron 36 niños con TEA y 36 controles con desarrollo típico (TD).
- Se construyeron redes funcionales estáticas y dinámicas de orden bajo y alto utilizando datos de EEG en estado de reposo en cuatro bandas de frecuencia (δ, θ, α, β).
- Se aplicaron métricas de teoría de grafos, entropía de estado y análisis de redes entre frecuencias.
Principales resultados:
- El TEA mostró conectividad alterada en bandas de frecuencia en redes de orden bajo y alto.
- Se observaron alteraciones topológicas pronunciadas en la banda α (menor coeficiente de agrupamiento y eficiencia, mayor longitud característica del camino) en el TEA.
- Las redes de orden superior exhibieron anomalías dinámicas específicas del tiempo y la frecuencia, con un acoplamiento mejorado relacionado con β en redes de orden bajo y reducciones generalizadas en redes de orden superior.
Conclusiones:
- Los niños pequeños con TEA muestran hipo e hiperconectividad coexistentes, topología de red alterada y dinámicas temporales anormales.
- La integración de análisis jerárquicos, dinámicos y entre frecuencias proporciona nuevas perspectivas sobre la neurofisiología del TEA.
- Estos hallazgos sugieren biomarcadores potenciales para el TEA.

Autism Spectrum Disorder
1.1K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Functions of Connective Tissues
16.4K
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.

The Electromagnetic Spectrum
65.1K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

The Electromagnetic Spectrum
33.6K
Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

Intrinsically Disordered Proteins
19.4K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

IR Spectrum
2.1K
When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...
