Summary
Electroencephalography (EEG) microstate sequences exhibit complex, non-Markovian dynamics. This study categorizes syntax analysis methods and proposes continuous EEG models for better understanding neural dynamics and replicability.
Area of Science:
- Neuroscience
- Computational Neuroscience
- Signal Processing
Background:
- Electroencephalography (EEG) microstates are quasi-stable periods of electrical potential distribution.
- Transitions between microstates form sequences reflecting neural dynamics.
- EEG microstate sequences show non-Markovian dependencies, indicating complex underlying processes.
Purpose of the Study:
- To advance the understanding of EEG microstate syntax and its functional significance.
- To facilitate methodological comparability and replicability in microstate research.
- To address the fragmentation and inconsistent terminology in the field.
Main Methods:
- Categorization of EEG microstate syntax analysis methods.
- Definition of three
- time-modes
- for microstate sequence construction.
- Outlining general issues in current microstate syntax analysis.
Main Results:
- Proposed categories for syntax analysis methods.
- Defined
- time-modes
- for sequence construction.
- Highlighted issues with current microstate syntax analysis methods.
Conclusions:
- Advocating for continuous EEG models to contextualize microstate models.
- Continuous approaches avoid
- winner-takes-all
- assumptions inherent in microstate derivation.
- Potential for developing more robust associative models with fMRI data.

01:35Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:01Neuroplasticity
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.
01:14Brain 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).

01:23Storage
A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...
