Remarkable changes have been observed in subjects at the alpha-theta crossover point. Houston therapist William Beckwith reports that clients who experience this crossover point also experience "the seemingly miraculous resolutions of complex psychological problems."

Research on the link between memory and theta waves shows that "the more theta waves appeared in an animal’s EEG after a training session, the more it remembered. This was true in all cases... Apparently, the best predictor of memory was the amount of theta waves recorded in the animal’s brain. [Theta waves] show that the brain is in the right state to process and store information."

Researcher Lester A. Henry noted that acetylcholine "is essential to such higher mental processes as learning and memory."

...meditation might alter the spatial distribution of attention by virtue of easing how fast the focus of attention is engaged and disengaged between spatial locations... Frontiers in Human Neuroscience. 2012; 6: 133. Published online 2012 May 15.
"...this study provides direct evidence that meditation alters spatial attention: while controls showed the typical global precedence effect, i.e., slower response times to local level targets as compared to global level targets (Navon, 1977), this effect was significantly reduced in the meditators. These results are in line with the hypothesis that meditation improves the allocation of attention in space and the ability to adjust the focus of attention from the larger, global pattern to the fine grained detail of an image. That is, meditation might alter the spatial distribution of attention by virtue of easing how fast the focus of attention is engaged and disengaged between spatial locations. Meditators did not only exhibit a strongly reduced global precedence effect, they were also overall much faster than controls, with an average advantage of more than 100 ms. This effect cannot be explained by a speed-accuracy trade-off in the meditator population, as accuracy was overall very high and comparable between groups. Altogether, these results suggest increased speed of processing along with improvements in the distribution of attentional resources in the meditator population."
In her book Beat Stress With Meditation, Naomi Ozaniec explains how meditation helps us get in touch with our more creative side:
... Meditation awakens the mind as a whole. As the mind is awakened it responds through creativity, which is a natural function ... Ozaniec, Naomi. Beat Stress With Meditation. London: Hodder Education,1997.
"Children create continuously through play and imagination. They are not inhibited by self-consciousness or hampered by doubting criticism. They simply create. This openness to each new experience is not unlike the openness of the meditative mind. When we are open to each moment, we can receive and we can create. Neither the creativity of the child nor the creativity of the meditative
In her book Beat Stress With Meditationmind gives rise to artistic endeavour that seeks public approval and acclaim. This is creativity for its own sake that seeks no further recognition. Meditation awakens the mind as a whole. As the mind is awakened it responds through creativity, which is a natural function (page 89)."
Ozaniec points out that "the correlation between mental activity and brainwave patterns has been known since the 1960s… Professor Richard Davidson, from the University of Wisconsin-Madison, currently proposes that meditative practice literally alters brain structure (page 220)."
