Modulation of Event-related Potentials of Visual Discrimination by Meditation Training and Sustained Attention.
Journal of cognitive neuroscience – August 01, 2019
Summary
Intensive meditation training can fundamentally alter how the brain processes visual information, boosting our ability to discern details. Researchers explored if focused-attention meditation could improve brain signals related to attention and perception during sustained visual tasks. Participants underwent two 3-month meditation retreats. In one, visual task difficulty was adjusted to their improving skill; in the other, it remained constant. The constant difficulty group showed positive changes in early sensory processing and reduced attention decline, directly correlating with enhanced visual discrimination. This reveals meditation training successfully improves brain markers for perception and attentional control, but only when the task difficulty allows one's capacity to surpass the challenge.
Abstract
The ability to discriminate among goal-relevant stimuli tends to diminish when detections must be made continuously over time. Previously, we repor...

Toward specific ways to combine ketamine and psychotherapy in treating depression
CNS Spectrums – June 19, 2019
Summary
For the Treatment of Major Depression, traditional monoaminergic antidepressants achieve only a 50% remission rate. Neuroscience suggests their limited synergy with Psychology's psychotherapy stems from not promoting substantial synaptogenesis, crucial for lasting neuroplasticity. Ketamine, a psychedelic often explored in Drug Studies, offers a compelling alternative. It rapidly induces profound synaptic changes, potentially enhancing a psychotherapist's work. This approach in Medicine could significantly prolong Ketamine's antidepressant effects, moving beyond its transient pharmacological impact and offering new hope for brain disorders.

Potential molecular pathways and therapeutic implications of rapid-acting antidepressants on myelin biology: a scoping review.
Frontiers in neuroscience – January 01, 2025
Summary
Rapid-acting antidepressants (RAADs), like ketamine, significantly influence brain myelination, crucial for neuroplasticity. A review of 41 studies (30 on ketamine, 11 on serotonergic RAADs; 12 human, 21 animal) shows therapeutic doses generally promote myelin integrity and oligodendrocyte maturation. This suggests RAADs impact neuronal activity-dependent myelination. Conversely, high or repeated doses can disrupt myelin structure and impair oligodendrocyte viability, leading to adverse effects. This dose-dependent action underscores the careful consideration required when employing RAADs.
