Summary
Low-resolution electromagnetic tomography neurofeedback (LORETA) improved executive functions and reduced psychopathology in participants. This brain training technique shows promise for enhancing self-regulation across diverse populations.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Psychiatry
Background:
- Self-regulation is crucial for mental well-being.
- Neural mechanisms underlying self-regulation are not fully understood.
- Brain neurofeedback offers a potential avenue for modulating brain activity.
Purpose of the Study:
- To investigate the effects of LORETA neurofeedback (LNFB) in the precuneus.
- To assess LNFB's impact on self-regulation in healthy controls and a psychiatric group.
- To evaluate changes in neurophysiology, executive functions, and psychopathology.
Main Methods:
- Thirteen participants (5 controls, 8 psychiatric diagnoses) underwent 10-20 LNFB sessions targeting the left precuneus.
- Neurophysiological measures were recorded.
- Pre- and post-assessments included the Personality Assessment Inventory (PAI) and Delis-Kaplan Executive Function System (DKEFS).
Main Results:
- Controls showed a significant increase in relative power in the precuneus.
- The psychiatric group did not reach significance in neurophysiological measures.
- All participants demonstrated improved executive functions and a trend towards reduced psychopathology.
Conclusions:
- LNFB in the precuneus enhances executive functions and reduces psychological symptoms in a mixed population.
- Alpha frequency may be linked to integrative functioning and self-regulation.
- LNFB shows potential as a tool for improving self-regulation and mental health.

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
