Somatosensation01:33

Somatosensation

40.8K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Sensory Perception: Organization of the Somatosensory System

8.6K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Hearing

54.3K
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.

Somatosensory, Motor, and Association Cortex

1.3K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

Auditory Pathway01:15

Auditory Pathway

6.1K
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...

Motor and Sensory Areas of the Cortex

5.2K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Audiology

Background:

  • Speech perception is a multisensory process involving auditory and visual information.
  • Embodied cognition suggests sensory input influences perception.
  • The impact of facial somatosensory input on audio-visual speech perception remains unclear.

Purpose of the Study:

  • To investigate if somatosensory stimulation of facial skin modulates audio-visual speech perception.
  • To examine the neural correlates of this modulation using event-related potentials (ERPs).
  • To test the embodied perspective of speech perception.

Main Methods:

  • Utilized the McGurk effect paradigm with congruent and incongruent audio-visual speech stimuli.
  • Recorded 64-channel electroencephalography (EEG) to measure event-related potentials (ERPs).
  • Applied somatosensory stimulation to facial skin during audio-visual speech presentation.

Main Results:

  • Somatosensory stimulation significantly improved the accuracy of identifying speech sounds (/ba/) in both congruent and incongruent conditions.
  • ERPs showed a divergence around 220 ms after somatosensory stimulation onset in the incongruent condition.
  • Neural activity was localized to temporal and occipital regions, indicating multisensory convergence.

Conclusions:

  • Somatosensory input to the face enhances audio-visual speech perception.
  • Results support the view of speech perception as an embodied, self-referenced, sensorimotor process.
  • Demonstrates multisensory integration between somatosensory and audio-visual speech information at both behavioral and neural levels.
