The neurological basis of speech motor control, the complex coordinated activity of tiny brain regions that controls our lips, jaw, tongue and larynx as we speak, is being uncovered by researchers.

It is a myth that the brain quits generating new cells once you reach adulthood. They are regenerating all the time.

"Speaking is so fundamental to who we are as humans - nearly all of us learn to speak. But it's probably the most complex motor activity we do," said senior author Edward Chang, MD, a neurosurgeon at the UCSF Epilepsy Center and a faculty member in the UCSF Center for Integrative Neuroscience.
The complexity comes from the fact that spoken words require the coordinated efforts of numerous "articulators" in the vocal tract - the lips, tongue, jaw and larynx - but scientists have not understood how the movements of these distinct articulators are precisely coordinated in the brain.
About Brain Tumor
Brain tumors are the abnormal growth of brain cells that may be benign or metastatic. Brain tumors account for about 2.4% of all the tumor diagnosesandare most challenging due to their critically delicate location.

They then applied a sophisticated new method called "state-space" analysis to observe the complex spatial and temporal patterns of neural activity in the speech sensorimotor cortex that play out as someone speaks. This revealed a surprising sophistication in how the brain's speech sensorimotor cortex works.

Brain Exercises to Improve Memory
An active brain can certainly help in improving memory by strengthening the connections between neural impulses in brain.

"These properties may reflect cortical strategies to greatly simplify the complex coordination of articulators in fluent speech," said Kristofer Bouchard, PhD, a postdoctoral fellow in the Chang lab who was the first author on the paper.
