In vertebrates, the cranial nerve afferents reporting to the brain the head acceleration sensed by the inner ear hair cells show a hypersensitivity, or upregulation, of the discharge response during the first days following microgravity exposure [7].
The FE head model predicts brain impact force and head acceleration curves show good agreement with those measured by experimental technique.
The WSTC was the first experimental, biomechanics-based, quantitative human brain injury criteria and it was defined based on linear head acceleration.
First, initial eye acceleration exceeded head acceleration.
The new study argues instead that blasts injure the brain by causing acceleration and deceleration of the head: "That would mean we're looking at the same type of injury in Afghanistan that we're looking at on the football field or in a car accident".
A common question regarding rodent models of TBI is whether the response of the lissencephalic (smooth, non-convoluted) rodent brain to impact, acceleration or blast injury is representative of that of the gyrencephalic human brain, which contains ridges (gyri) and furrows (sulci).
This might be a reason for the acceleration of brain atrophy after clearance of Aβ by antibodies in the AN1792 trials [ 7].
Abnormal acceleration of brain growth in early childhood, signs of slower growth of neurons, and minicolumn developmental abnormalities suggest multiregional alterations.
27 Second, weekly interferon treatment has not been reported to be associated with "pseudoatrophy," and there was no acceleration of brain volume loss after interferon initiation at month 3 in the study compared to first 3 months.
As examples of the commonalities between the two pathologies, recent studies indicate that T2DM, like AD, produces a variety of neurochemical, neuroanatomical, and behavioral changes that can be linked to acceleration of brain aging, increased oxidative stress, and neuroendocrine alterations.
