The basal ganglia and pain

Area of Science:

• Neuroscience
• Cognitive Neuroscience

Background:

• The basal ganglia are primarily known for motor control functions.
• Emerging evidence suggests diverse nonmotor roles for the basal ganglia.
• The precise functions of the basal ganglia beyond motor control require further elucidation.

Purpose of the Study:

• To review the literature on the basal ganglia and their association with nonmotor functions.
• To investigate the potential role of the basal ganglia in pain processing.
• To explore a novel function for the basal ganglia in selective attention.

Main Methods:

• Literature review of studies investigating basal ganglia functions.
• Analysis of research linking basal ganglia activity to pain perception.
• Examination of evidence for basal ganglia involvement in attentional processes.

Main Results:

• The literature review indicates a significant association between the basal ganglia and pain.
• Evidence suggests the basal ganglia may play a role in modulating pain perception.
• Findings raise the possibility of the basal ganglia contributing to selective attention mechanisms.

Conclusions:

• The basal ganglia's functional repertoire extends beyond motor control.
• A potential role for the basal ganglia in pain modulation is supported by current literature.
• The basal ganglia may subserve a novel function in selective attention, warranting further investigation.
