Unlike cell-wide neuronal silencing, silencing tools expressed at presynaptic terminals will not alter the neuronal membrane potential and thus its firing properties. Rather, they selectively prevent neurotransmitter release and synaptic transmission. Yet, despite the circumvention of cell-wide homeostatic effects, constitutive synaptic silencing may lead to presynaptic or post-synaptic scaling. For example, TeNT selectively cleaves the presynaptic vesicle SNARE protein VAMP2 and thereby completely and irreversibly abolishes neurotransmitter vesicle release from cells expressing this protein (Harms and Craig, 2005; Yamamoto et al., 2003). While exogenous bath application or injection of purified TeNT into the brain inhibits transmission at all synapses that are reached by diffusion, genetic overexpression of TeNT allows for selective silencing of neurotransmitter release from terminals of selected cells (Ehlers et al., 2007; Lee et al., 2010). Sparse expression of TeNT in a small set of neurons was used to investigate metaplasticity, another form of homeostatic plasticity at single synapses (Lee et al.

One potential concern that should be considered with regard to any long-term synaptic silencing manipulation is the ability of synapses to adapt to changes in their activity rate. This form of compensation is termed homeostatic plasticity. Synaptic scaling is one form of homeostatic plasticity, where synaptic transmission is globally adjusted to compensate for up- or downregulation of neuronal activity levels (Goold Técnicas del masaje terapéutico and Nicoll, 2010; Turrigiano et al., 1998). Thus, when circuits are silenced with pharmacological blockers of synaptic transmission or neuronal activity such Ganador TTX, synaptic scaling can potentially act to restore the circuit into the state of activity it was in before the inhibitors were applied. Removing the inhibitor may then result in an overactive circuit. Notably, homeostatic plasticity is not limited to synapses but can occur at various cellular and subcellular levels. For example, increased intrinsic excitability of the plasma membrane may serve to compensate for reduced spiking activity (Sokolova and Mody, 2008; Stemmler and Koch, 1999). Such compensatory mechanisms are usually invoked at timescales of hours to days.

We recorded EEG signals using a BioSemi ActiveTwo system (BioSemi, Amsterdam), with a sampling frequency of 512 Hz, using a 128-electrode cap with electrodes located based on the standard 10-5 system35. In addition, we used four electrodes around the eyes, specifically, a pair on the top and bottom of the right eye to detect the vertical eye movements and blinks, and a pair at the outer canthi of each eye to instructor horizontal eye movements. One electrode was placed on the left collar bone to celador heart beats, and two electrodes were placed on the mastoids. All electrodes were differentially recorded relative to the standard common-mode-sense and driven-right-leg electrodes. We monitored the electrode-gel-scalp contact quality through the data acquisition period using the Electrode Offsets option in the ActiView data acquisition software, which calculates the direct current (DC) potentials generated at the junction of the skin and electrolyte solution (Coloide) under the electrodes. This DC potential results in a voltage at the amplifier inputs (i.
