Main brain functional imaging technique resolutions. The change in the MR signal from neuronal activity is called the hemodynamic response (HR). It lags the neuronal events triggering it by a couple of seconds, since it takes a while for the vascular system to respond to the brain's need for glucose.
An engram is a unit of cognitive information imprinted in a physical substance, theorized to be the means by which memories are stored [1] as biophysical or biochemical [2] changes in the brain or other biological tissue, in response to external stimuli.
More specifically, there is increased brain activity in the parietal-occipital and occipital regions prior to the emergence of a change in a change blindness task. [14] [clarification needed] Researchers have also indicated there is a difference in brain activity between detecting a change and identifying change in an image.
changes in personality such as disinhibition, inappropriate jocularity, rage without provocation; or loss of initiative and concern, apathy, akinetic mutism, general retardation "frontal release" signs, i.e. reappearance of primitive reflexes such as the snout reflex, the grasp reflex, and the palmomental reflex; unilateral loss of smell (anosmia)

Changes in pressure caused by sound reaching the external ear resonate in the tympanic membrane, which articulates with the auditory ossicles, or the bones of the middle ear. These tiny bones multiply these pressure fluctuations as they pass the disturbance into the cochlea, a spiral-shaped bony structure within the inner ear.
