Resumen
Los bebés recién nacidos pueden controlar deliberadamente los movimientos de sus brazos cuando pueden verlos. Esto sugiere que el control visual del movimiento del brazo se desarrolla muy temprano en la infancia.
Área de la Ciencia:
- Neurociencia del desarrollo neurológico.
- El control motor del bebé.
- La percepción visual es la percepción visual.
Sus antecedentes:
- Los movimientos del brazo del recién nacido a menudo se consideran reflexivos y no intencionales.
- Existe una comprensión limitada con respecto a la integración visual-motora temprana en los bebés.
- La capacidad de control motor voluntario en los recién nacidos es un área de investigación en curso.
Objetivo del estudio:
- Investigar si los recién nacidos pueden ejercer un control intencional sobre los movimientos de sus brazos.
- Para determinar el papel de la retroalimentación visual en la modulación de los movimientos del brazo neonatal.
- Para evaluar el desarrollo temprano del control visual del movimiento de las extremidades.
Principales métodos:
- Se registraron movimientos espontáneos de los brazos en recién nacidos acostados en supina.
- Entrada visual manipulada: vista directa del brazo, vista del monitor de video o sin vista del brazo.
- Se aplicaron pequeñas fuerzas perturbadoras a las muñecas para evaluar las respuestas motoras.
Principales resultados:
- Los recién nacidos se opusieron activamente a las fuerzas externas para mantener el movimiento normal del brazo cuando podían ver su brazo.
- Esta respuesta visual-motora se produjo si el brazo se veía directamente o a través de un monitor de video.
- El control disminuía cuando el brazo no era visible.
Conclusiones:
- Los recién nacidos demuestran un control intencional de los movimientos de los brazos en respuesta a perturbaciones externas.
- La retroalimentación visual es crucial para modular estos movimientos voluntarios del brazo poco después del nacimiento.
- El desarrollo del control visual sobre el movimiento del brazo comienza en el período neonatal.

00:51Anatomical Movements
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:19Brainstem
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:22Indirect Motor Pathways
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

01:08Reflex Activity
A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
