Area of Science:

  • Neuroscience
  • Medical Imaging
  • Neurology

Background:

  • Tremor is a neurological disorder affecting motor control.
  • Understanding the functional brain anatomy in tremor is crucial for developing effective treatments.

Purpose of the Study:

  • To review insights from PET and MRI studies on the functional anatomy of different tremor types.
  • To consider the effects of pharmacologic and interventional treatments on cerebral systems in tremor.
  • To speculate on the neuropharmacologic basis of tremors using in vivo PET evidence.

Main Methods:

  • Review of existing literature on PET and MRI activation studies in tremor.
  • Analysis of studies investigating treatment effects on brain activity in tremor patients.
  • Synthesis of in vivo PET data to infer neuropharmacologic mechanisms.

Main Results:

  • PET and MRI studies have elucidated the functional brain networks involved in various tremors.
  • Pharmacologic and interventional treatments show modulatory effects on dysfunctional cerebral systems.
  • In vivo PET data provide a basis for understanding the neuropharmacologic underpinnings of tremor.

Conclusions:

  • Neuroimaging techniques like PET and MRI are vital for understanding tremor pathophysiology.
  • Treatment strategies can target specific dysfunctional brain circuits identified through neuroimaging.
  • Further research into the neuropharmacologic basis of tremor is warranted based on imaging evidence.
