Summary
Sensorimotor rhythm (SMR) neurofeedback training enhances performance and increases SMR power in somatosensory areas. This neuromodulation also improves functional connectivity in these brain regions during rest.
Area of Science:
- Neuroscience
- Neuromodulation
- Neurofeedback
Background:
- Sensorimotor rhythm (SMR) neurofeedback trains individuals to modulate cortical activity.
- While SMR power modulation is established, its effects on brain networks are less understood.
Purpose of the Study:
- To investigate performance enhancement and EEG power spectral density changes in somatosensory areas after SMR neurofeedback.
- To explore functional connectivity alterations in somatosensory areas during resting state post-training.
Main Methods:
- A six-session bidirectional SMR neurofeedback protocol was used.
- Functional magnetic resonance imaging (fMRI) resting-state scans were conducted before and after training in a subset of participants.
Main Results:
- Participants demonstrated improved performance and increased SMR power in somatosensory regions.
- Enhanced functional connectivity was observed between somatosensory areas during resting state after training.
Conclusions:
- SMR neurofeedback training leads to measurable improvements in performance and brain activity.
- The study enhances understanding of EEG neuromodulation and its clinical applications for somatosensory function.

Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.

The power and energy delivered to an element are subjects of great significance in the field of electrical engineering. It is a well-known fact that a 100-watt light bulb emits more light than a 60-watt one. Therefore, power and energy calculations play a crucial role in the analysis of electrical circuits.
Power, defined as the time rate of expending or absorbing energy, is quantified in units called watts (W). The relation between power and energy is mathematically given as
