... We set out to examine PSD-95 de novo protein synthesis at individual synaptic sites preserving both molecular specificity and spatial information. To this end, we first established a pulse-chase strategy using spectrally separated, live-cell compatible HaloTag substrates applied to neuronal cultures at different time points (21,22). In detail, the chimeric PSD-95-HaloTag protein in the cells was labeled to saturation with the first fluorescent Halo substrate (pulse, 580CP-Halo, 1 µM for 2 h). ...

... Because synapses rely on a variety of postsynaptic scaffolding proteins for stabilization, 40,41 we extended our analysis to synapse-associated protein 102 (SAP102), a postsynaptic scaffolding protein that is present in a separate subset of synapses throughout the brain. 42 Total number of VGLUT1 + -SAP102 + synapses did not change after reactivation of engram B in the linked group ( Figures S4C-S4F), neither did the expression of SAP102 ( Figure S4G). Finally, we explored whether the increase in engram B activation induced by recall of A 0 in the updated group could be explained by a change in the inhibitory tone that these cells receive. ...

... Somewhat similarly, Pohl et al. have investigated the scenario of in-home streaming and propose the use of foveated compression in tandem with consumption-side gaze tracking to reduce the network load incurred by texture-compressed dynamic light fields [35]. Finally, Koniaris et al. promote the use of view-dependent decoding (i.e., transmit only those parts of the source videos of dynamic light fields that are visible to viewers) as well as view prioritization heuristics to make sure that the input views with the largest contribution to light field reconstruction are given streaming precedence [4,19]. ...

... Annexing Reality predicts possible overlays of virtual objects onto the nearest physical match in the player's view, like a bottle representing a light-saber [24]. IRIDiuM+ includes the active and passive "walkable haptics" of vibrating carpetlike materials and the "air haptics" of actuated fans [34]. Work that considers both the user and the environment begins to resemble interactive theatre (e.g., Sleep No More [51]), in which a user interacts within the bounds of a constructed space. ...

... Recent advancements in neural interfaces have demonstrated the great potential of interactive devices that directly interface with the human body and interpret neuronal activities for downstream tasks [Anumanchipalli et al. 2019;Flesher et al. 2021;Hochberg et al. 2012;Willett et al. 2021]. Among these interfaces, EMG has emerged as a promising interaction medium, especially in VR and AR [Hirota et al. 2018;Koniaris et al. 2016;Tsuboi et al. 2017]. A major benefit of EMG for immersive interaction is the potential that it offers for completely bypassing the often-used solution of camera-based tracking, which has serious side effects of being open to limitation by occlusions and field of view [Pai et al. 2019]. ...

... A series of prototyping toolkits associated with vibrotactile arrays have become popular among research domains [31,63,64], and useful for conveying a unique set of sensory feedback on the skin. VITAKI [42] and Stereohaptics [24] are vibrotactile prototyping toolkits targeting prototyping and testing of new interactions for virtual reality applications and video games. They presented hardware and software elements that facilitate the overall functioning of the actuators together with the virtual contents. ...
