Objectives: Toothaches are often poorly localized. Although periodontal pain is better localized, it can spread to other areas. Ultimately, the cerebral cortex processes nociception, with somatotopic organization possibly playing a role in localizing the origin.

Tactile feedback from brain-controlled bionic hands can be partially restored via intracortical microstimulation (ICMS) of the primary somatosensory cortex. In ICMS, the location of percepts depends on the electrode's location and the percept intensity depends on the stimulation frequency and amplitude. Sensors on a bionic hand can thus be linked to somatotopically appropriate electrodes, and the contact force of each sensor can be used to determine the amplitude of a stimulus.

Significance: Auriculotherapy is a technique based on stimulation applied to specific ear points. Its mechanism of active and clinical efficacy remain to be established. This study aims to assess the role that primary somatosensory cortex may play to validate auriculotherapy mechanisms.

Article Synopsis
- - Disorders of the trigeminal nerve can lead to significant complications in dental practice, such as neuropathic pain, and understanding the trigeminal ganglion's structure is crucial for managing these issues.
- - The trigeminal ganglion is a complex environment where various cells interact through direct contact or biochemical mediators like ATP and cytokines, which can influence pain responses.
- - Research has highlighted the close proximity of ganglion cells related to different facial areas, suggesting that their interactions may play a role in creating ectopic pain, emphasizing the need for a detailed understanding of these cellular networks.
Somatotopy of the sensory thalamus: inputs from directional deep brain stimulation in pain patients.

Objective: The sensory ventroposterior (VP) thalamic nuclei display a mediolateral somatotopic organization (respectively head, arm, and leg). We studied this somatotopy using directional VP deep brain stimulation (DBS) in patients treated for chronic neuropathic pain.
Methods: Six patients with central (four) or peripheral (two) neuropathic pain were treated by VP DBS using directional leads in a prospective study (clinicaltrials.
