We provide evidence that YFP can detect morphological and plastic alterations in the SOD1G93A mouse, and that the pre- and post-synaptic integrity of the NMJ plays an important role in the pathogenic mechanisms of ALS.
We conclude that both needle and shoot level modifications contribute to plastic alterations in shoot light harvesting efficiency in P. sylvestris, but also that site fertility may significantly constrain the light-acclimation in shoot architecture.
Plastic alterations to AIS structure can therefore occur rapidly when induced by physiologically relevant patterns of elevated activity.
We suppose that they are then rapidly followed by protein expression and these proteomic alterations translate short-lived transcriptional drug effects into lasting structural modifications of the brain; further, we suggest that chronic drug treatment leads to accumulation of drug-induced plastic alterations that eventually become manifest as therapeutic effects.
Several lines of evidence indicate that the expression of genes belonging to network α is involved in the initiation of plastic alterations and long-term modulation of neuronal signaling and the diverse functions of these genes indicate that psychotropic drugs activate control points for multiple intracellular pathways [ 44].
Plastic CNS alterations might explain the complex sensory symptoms (e.g. glove-stocking sensory loss, 'foreign-hand' sensation, mislocalization after tactile stimulation, impaired perceptual learning ability).
Thus, at least in principle, TMS/hd-EEG may be employed at the patient's bedside to track over time pathological alterations, plastic changes and therapy-induced modifications in cortical circuits.
In principle, identifying a cut-off level above which one can decide whether a change in brain responsiveness occurred, or not, is crucial if one wants to use TMS/hd-EEG to track over time pathological alterations, plastic changes and therapy-induced modifications in cortical circuits.
High-density electroencephalography (hd-EEG) combined with transcranial magnetic stimulation (TMS) provides a direct and non-invasive measure of cortical excitability and connectivity in humans and may be employed to track over time pathological alterations, plastic changes and therapy-induced modifications in cortical circuits.
A feature called "Knifestyles of the rich and famous" compares two photos of a famous person taken a few years apart, with commentary by a plastic surgeon on the alteration.
