Summary
Gamma oscillations in the basal ganglia are increasingly studied for their role in movement. This review explores their functional anatomy and connection to movement parameter coding in conditions like Parkinson's disease.
Area of Science:
- Neuroscience
- Motor Control
- Basal Ganglia Research
Background:
- Beta activity in the basal ganglia gained prominence following its identification in Parkinson's disease.
- Gamma frequency neuronal synchronisation in the basal ganglia is a less explored but significant phenomenon.
Purpose of the Study:
- To review existing data on gamma oscillations in the basal ganglia.
- To discuss the functional anatomy of gamma activity within this network.
- To investigate the relationship between gamma activity and movement parameter coding.
Main Methods:
- Literature review of studies on gamma oscillations in the basal ganglia.
- Analysis of data linking gamma activity to movement and disease states.
- Discussion of neuroanatomical pathways involved in basal ganglia gamma activity.
Main Results:
- Gamma oscillations are observed in a distributed network including the basal ganglia, thalamus, and motor cortex.
- Gamma activity is associated with various diseases, increased arousal, and voluntary movement.
- Dopaminergic therapy promotes gamma activity in Parkinson's disease, correlating with limb kinematics.
Conclusions:
- Gamma oscillations in the basal ganglia may play a role in movement production.
- Further research is needed to clarify the precise relationship between basal ganglia gamma activity and movement parameter coding.

01:04Oscillations about an Equilibrium Position
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so because...
01:23Brain Waves
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:
01:06Forced Oscillations
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.
01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:30Oscillations In An LC Circuit
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by
01:27Diencephalon: Thalamus and Information Relay
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological states or needs.
