Editorial Reviews. nvrehs.info Review. When you look at the popularity of mind- body medicine today, it's hard to understand what a groundbreaking book this. The term, 'Relaxation Response' was coined by Dr. Herbert Benson, book The Relaxation Response, Dr. Benson describes the scientific. The Relaxation Response is a natural innate protective mechanism which allows us to turn off harmful effects from stress through changes that decrease heart.
The optic nerve has on-fibers and off-fibers that respond to the on and off status of light, respectively[ 13 ]. A previous study using electroretinograms reported that the latency of response was shorter with light-on than with light-off[ 14 ].
Our results regarding the C-RT might reflect the effect of these latencies[ 6 ], whereas our R-RT findings are unlikely to be explained by this latency. The posterior parietal cortex is concerned with visuo-motor integration[ 15 ] and interacts with the cerebellum, which is critically associated with and mimics sensory-motor states[ 16 ].
Thus it seems likely that the visuo-motor process is associated with input from each optic nerve. Therefore, the length of C-RT or R-RT during the light on status or off status might involve not only afferent activity but also higher-order brain processing.
The distal muscles have a larger cortical representation, and a previous study underlined the functional relevance of the powerful monosynaptic projections of these muscles[ 17 ].
Studies of movement-related cortical potentials and functional neuroimaging have shown that voluntary muscle relaxation is preceded and accompanied by activation of primary and supplementary motor areas[ 18 — 22 ]. In addition, as the neuronal clusters are connected to the primary motor cortex, it appears that these connections exert an inhibitory influence, at least in part[ 23 , 24 ].
The inhibitory influence is generally believed to test excitability of the GABAA-ergic system in the motor cortex, as well as short-interval intracortical inhibition SICI. Indeed, the SICI decreases just before the onset of a voluntary contraction[ 25 ]. Hence removing ongoing inhibition can contribute to the increased excitability of the cortical motor pool, and the opposite process would occur with voluntary relaxation.
Toma et al.
Conclusions In conclusion, this study found that as the contraction level increased, the R-RT became longer than the C-RT regardless of light status. Embed Size px. Start on.
