Summary #

The presentation provides an overview of the scientific foundations of neurofeedback, illustrating the evolution of EEG, its cortical origins, and the application of modern quantitative EEG (qEEG) and Z-score–based training in clinical practice.

History of Human EEG #

Early work by Hans Berger in the 1920s–1930s established the first human EEG recordings, laying the groundwork for contemporary neurophysiological assessment.

Cortical EEG Sources and Brain Dynamics #

Cortical vs. Scalp-Level Activity #

The slides highlight distinctions between cortical and scalp-recorded EEG, demonstrating how spatial resolution (e.g., 1 cm invasive spacing) enhances the clarity of neural signals.

Neurophysiological Models #

Content includes:

• Thalamo-cortical cycles

• The alternation of concentration and relaxation states

• Neural network engineering diagrams demonstrating functional integration

Foundations of Z-Score Neurofeedback #

Z-score training uses normative databases to guide neurofeedback toward statistically typical EEG patterns. The presentation illustrates real-world examples of live Z-score progress maps and pre/post qEEG shifts.

Clinical Examples and Case Data #

Quantitative EEG (qEEG) Pre/Post Comparisons #

Multiple case demonstrations include:

• Pre/post Z-score maps

• Eyes-closed qEEG changes

• sLORETA-based source analysis

Illustrative Case Summary #

One detailed case (“BF”) documents baseline challenges (communication delays, social difficulties, behavioral dysregulation, sleep disruptions) followed by observed post-training changes such as:

• Increased spontaneous communication

• Greater social engagement

• Improved behavioral self-regulation

• More consistent sleep patterns

These observations reflect caregiver and clinician reports from this specific case example and do not constitute generalizable outcomes.

Key Insights #

• EEG provides a measurable window into cortical function.

• Neurofeedback and Z-score training are positioned as tools to help guide brain activity toward more regulated patterns.

• qEEG and sLORETA visualizations support assessment, training planning, and documentation of client progress.
