Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

6.0K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Neurons as Communicators of the Brain

5.3K
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.

Prosopagnosia01:24

Prosopagnosia

1.3K
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

377
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Área de la Ciencia:

  • La neurociencia
  • Ingeniería biomédica
  • Inteligencia artificial

Sus antecedentes:

  • Restaurar la comunicación para las personas con parálisis es un desafío significativo.
  • Las neuroprótesis de habla existentes a menudo carecen de velocidad y expresividad naturalistas.
  • La parálisis grave de las extremidades y la voz limita gravemente las habilidades de comunicación.

Objetivo del estudio:

  • Desarrollar una neuroprótesis de habla de alto rendimiento en tiempo real.
  • Para permitir la salida de comunicación multimodal (texto, audio del habla, animación facial).
  • Para restaurar la comunicación corporal de las personas con parálisis severa.

Principales métodos:

  • Grabaciones de electrocorticografía de superficie de alta densidad (ECoG) de la corteza del habla.
  • Modelos de aprendizaje profundo entrenados en datos neuronales de intentos de habla silenciosa.
  • Decodificación en tiempo real a través de texto, habla sintetizada y modalidades de animación de avatares.

Principales resultados:

  • Logró una rápida decodificación de texto de gran vocabulario a 78 palabras por minuto con una tasa de error de palabra del 25%.
  • Demostró una síntesis de voz inteligible y personalizada, que coincide con la voz del participante antes de la lesión.
  • Habilitado el control de la animación facial-avatar para el habla y los gestos no verbales.
  • Alto rendimiento del decodificador alcanzado en dos semanas de entrenamiento.

Conclusiones:

  • Un enfoque neuroprótesis del habla multimodal muestra una promesa significativa para restaurar la comunicación.
  • Esta tecnología puede proporcionar una comunicación completa y encarnada para las personas con parálisis severa.
  • El entrenamiento rápido y el alto rendimiento indican la viabilidad clínica para las interfaces cerebro-computadora.
