Hearing

52.4K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

244
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Auditory Pathway01:15

Auditory Pathway

5.4K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

科学领域:

  • 神经科学是一个神经科学.
  • 听觉神经科学 听觉神经科学
  • 运动医学 运动医学

背景情况:

  • 脑震荡是接触体育运动中的一个重要问题,但人们对脑震荡下冲击的影响知之甚少.
  • 需要客观的措施来确定不符合临床脑震荡标准的头部创伤.

研究的目的:

  • 测试听力处理的客观测量,频率跟踪响应 (FFR) 是否可以揭示不符合脑震荡定义的头部创伤史.
  • 调查接触和非接触大学运动员之间的FFR差异.

主要方法:

  • 在19项体育运动中评估了709名NCAA第一师学生运动员,他们使用FFR对语音刺激.
  • 根据运动类别将运动员分为"接触"和"非接触"组.
  • 批判性地检查了基本频段 (F0) 中的FFR活动幅度.

主要成果:

  • 与非接触运动员相比,接触运动员的FFR-F0振幅较低.
  • 观察到女性比男性的FFR-F0幅度更高.
  • 确定了显著的相互作用效应,接触运动的男性显示最小的FFR-F0.0.

结论:

  • 听觉感官处理中的干扰在运动员中可以检测到经常身体接触,即使没有脑震荡.
  • FFR代表了运动员中脑震荡下头部创伤的客观生物标志物.
  • 这些发现突出了FFR监测累积头部冲击效应的潜力.
