Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
The stretch reflex (myotatic reflex), or more accurately "muscle stretch reflex", is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints. [ 1 ]
A muscle spindle, with γ motor and Ia sensory fibers. A type Ia sensory fiber, or a primary afferent fiber, is a type of afferent nerve fiber. [1] It is the sensory fiber of a stretch receptor called the muscle spindle found in muscles, which constantly monitors the rate at which a muscle stretch changes.
3. Get crafty. The simple act of making something can be a great way to stimulate your brain. Great examples of activities like this include: Baking
When a muscle spindle is stretched, the stretch reflex is activated, and the opposing muscle group must be inhibited to prevent it from working against the contraction of the homonymous muscle. This inhibition is accomplished by the actions of an inhibitor interneuron in the spinal cord. [3]
Gadolinium (Gd 3+) and other lanthanides have been shown to block stretch-activated ion channel function. The peptide toxin isolated from the Chilean rose tarantula ( Grammostola rosea , synonym G. spatulata ), mechanotoxin 4 (GsMTx4) has been shown to inhibit these channels from the extracellular side, but it does not inhibit all stretch ...
A new study from the Salk Institute for Biological Studies has identified a brain circuit that slows the breath to calm the mind. Skip to main content ...
The result is a feeling of increased muscle control, flexibility, and range of motion. Stretching is also used therapeutically to alleviate cramps and to improve function in daily activities by increasing range of motion. [2] [3] In its most basic form, stretching is a natural and instinctive activity; it is performed by humans and many other ...
