Now, researchers at UC San Francisco have succeeded in mapping the genetic signature of a unique group of stem cells in the human brain that seem to generate most of the neurons in our massive cerebral cortex.
In their study, the researchers found they could predict with "a relatively high degree of accuracy an individual's genetic ancestry based on the geometry of their cerebral cortex.
It seems paradoxical, but we suspect that the particular ultrasound waveform we used in the study alters the balance of synaptic inhibition and excitation between neighboring neurons within the cerebral cortex," lead author William "Jamie" Tyler said.
In humans, the cerebral cortex is the largest part of the brain, and the region responsible for memory, sensory perception and language.
In exposed animals, the glutamate receptor GluAl was decreased in hippocampus, while glia were activated and inflammatory cytokines were induced in cerebral cortex.

Sarova-Pinhas found that, compared with patients with longer disease duration, patients with shorter duration disease had significantly larger volumetric measurements of the right cerebral cortex (274 vs.
Paralleling the arrangement in that core text, he summarizes such topics as meningeal coverings of the brain and spinal cord, electrical signaling by neurons, the organization of the brainstem, the visual system, basal ganglia, the cerebral cortex, and the hypothalamus and limbic system.
The innovative sensor design effectively removes surface tissue effects that can influence measurement accuracy -- isolating measurements of the cerebral cortex and providing rSO2 values.
The thoughtful, more-evolved cerebral cortex is now engaged, and you plan on removing Skinner's hooks one at a time.
So do all of our physiological and neurological processes, including the inputs to our cerebral cortex from our sense organs and from our limbic system, which controls our emotions.
Doctors at Siriraj Hospital in Bangkok performed computed tomography and magnetic resonance imaging scans on the king and found the monarch was suffering from a mild deficiency in the supply of blood to the left cerebral cortex, according to a statement issued by the bureau.
Elevation of conjugated diene levels, the index of lipid peroxidation and cell damage was reported in the cerebral cortex region after ischemia and reperfusion)
