Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
Plasticity
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Summary
Invasive brain-machine interfaces (BMIs) show rapid neural plasticity during learning. This research highlights the importance of neural-operant paradigms for advancing neurorehabilitation and high-performance BMIs.
Area of Science:
- Neuroscience
- Biomedical Engineering
Context:
- Brain-machine interfaces (BMIs) offer a way to control external devices using neural signals.
- Invasive BMIs, though more complex, hold greater future potential than noninvasive types.
- Understanding neural plasticity is key to advancing BMI technology.
Purpose:
- To review recent studies on invasive BMIs, focusing on neural plasticity.
- To investigate rapid, plastic changes in neuronal activity during BMI use.
- To explore the role of the neural-operant paradigm in BMI research.
Summary:
- Studies using invasive BMIs in rats and monkeys show significant neural plasticity during device operation learning.
- A high-performance BMI system demonstrated rapid changes in hippocampal neuron firing and synchrony in rats.
- Neural plasticity is induced by the contingency between neural activity and rewards.
