Paired-pulse fEPSPs were evoked using 100 μs duration stimulations spaced 20 ms apart.
Recently, we have shown that the neocortex of freely moving rats reliably supports LTP, provided that the stimulation is spaced and repeated over days.
Despite this potential advantage, it remains to be seen if these theoretical predictions result in a measurable clinical effect that outweighs the added complexity of the expanded stimulation parameter search space generated by the more flexible technology.
The induction of STAT1 binding by IFN-γ stimulation and the spacing of GAS tandems exhibit considerable heterogeneity as displayed in Fig. 4, equally for sites within repetitive as well as within non-repetitive sequences.
These results further demonstrate the biological relevance associated with the ability of the female to space coital stimulation received during mating.
The aim was to investigate the immunoreactivities for NOS enzymes in frontal cortex and meningeal vessels after chemical stimulation of the subarachnoid space of adolescent rats and the effect of sumatriptan pre-treatment on the immunoreactivities of the NOS enzymes.
The mean values of immunolabeling intensities for NOS enzymes in frontal cortex and meningeal vessels were significantly reduced in group 3 compared to group 2. These results suggest that, chemical stimulation of the subarachnoid space increased the immunoreactivities of NOS enzymes in the brain of adolescent rats.
The aim of this study was to investigate the immunoreactivity for NOS enzymes in meningeal vessels and frontal cerebral cortex after the chemical stimulation of the subarachnoid space of adolescent rats and the effect of sumatriptan on the immunoreactivity for the NOS enzymes.
Plain stimuli may drive networks to the nearest equilibrium that accommodates this input, whereas adaptive stimulation may direct the space for exploration and force networks to a new balance, at a larger distance from the initial state.
We measured the degree of overlap between positions at different hierarchical levels of the visual system (V1 V4v) and quantified modulatory effects on a specific position by stimulation at neighboring (1.7° spacing) or distant positions (5.1° or 8.5° spacing).
Synaptic boutons were stimulated by electric field stimulation (platinum electrodes, 10-mm spacing, 1-ms pulses of 50 mA with alternating polarity).
