Somatosensation

Somatosensation

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.

Somatosensory, Motor, and Association Cortex

Somatosensory, Motor, and Association Cortex

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...

Motor and Sensory Areas of the Cortex

Motor and Sensory Areas of the Cortex

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....

Summary

This summary is machine-generated.

Neural responses in the auditory cortex are suppressed during speech to enhance auditory feedback sensitivity, aiding vocalization error detection. This study confirms this link in humans, crucial for speech monitoring.

Area of Science:

Neuroscience
Auditory Perception
Speech Production

Background:

Neural responses in the auditory cortex are suppressed during vocalization across species.
This suppression is hypothesized to increase sensitivity to auditory feedback for error detection.
Previous evidence in non-human primates supports this, but a direct link in human speech monitoring was lacking.

Purpose of the Study:

To investigate the relationship between auditory suppression during speech and auditory feedback sensitivity in humans.
To determine if brain regions with suppressed auditory responses are also sensitive to altered auditory feedback.
To explore the role of attentional load in modulating auditory feedback sensitivity.

Main Methods:

Intracranial electroencephalography (iEEG) recordings from 35 neurosurgical participants during speech production.
Characterization of the topography of auditory suppression across the superior temporal gyrus (STG).
Delayed auditory feedback (DAF) task to assess sensitivity to feedback alterations at suppressed sites.

Main Results:

Auditory suppression topography varied across the STG.
Sites exhibiting auditory suppression also showed enhanced responses to altered auditory feedback, confirming sensitivity.
A strong correlation was found between the degree of auditory suppression and feedback sensitivity.
Posterior STG activation increased during DAF, suggesting attentional load modulates feedback sensitivity.

Conclusions:

Auditory suppression during vocalization is a key mechanism for human speech monitoring.
The degree of auditory suppression directly correlates with sensitivity to auditory feedback alterations.
Attentional load, particularly in a DAF paradigm, can modulate auditory feedback sensitivity in the posterior STG.
