Inertial Frames of Reference01:03

Inertial Frames of Reference

9.2K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference

7.7K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

3.1K
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...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.2K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Indirect Motor Pathways01:22

Indirect Motor Pathways

3.7K
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...

Equilibrium and Balance01:15

Equilibrium and Balance

6.8K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Resumen
Este resumen es generado por máquina.

Los sesgos motores en los movimientos dirigidos a objetivos provienen de desalineaciones en las representaciones espaciales, no de errores sensoriales o biomecánicos. Este hallazgo aclara el origen de los errores sistemáticos en el control motor humano.

Sus antecedentes:

  • Los movimientos dirigidos a objetivos dependen de la percepción y los sistemas motores precisos.
  • Los errores en estos sistemas pueden conducir a fallos en el movimiento, incluidos sesgos motores sistemáticos.
  • El origen preciso de estos sesgos sistemáticos es objeto de debate continuo.

Objetivo del estudio:

  • Evaluar modelos computacionales que explican el origen de los sesgos motores.
  • Investigar si los sesgos motores surgen de factores sensoriales o biomecánicos.
  • Identificar la causa principal de los sesgos motores sistemáticos en los movimientos humanos.

Principales métodos:

  • Análisis de datos extensos de tareas de alcance que abarcan 30 años.
  • Evaluación de varios modelos computacionales de sesgo motor.
  • Comparación de las predicciones del modelo con los datos empíricos de participantes humanos.

Principales resultados:

  • Los sesgos motores no se originan en errores en la posición de la mano detectada durante la planificación motora.
  • Las restricciones biomecánicas durante la ejecución motora no explican los sesgos motores.
  • Los sesgos motores son causados principalmente por una desalineación entre las representaciones de posición centradas en el ojo y centradas en el cuerpo.

Conclusiones:

  • El modelo propuesto de desalineación de la representación espacial explica los sesgos motores en diversas condiciones.
  • Esto incluye variaciones en la mano utilizada, el tipo de movimiento, la visibilidad de la posición inicial y la adaptación sensoriomotora.
  • Los hallazgos desafían teorías anteriores y ofrecen una explicación unificada para los sesgos motores.
