Channelrhodopsin-assisted circuit mapping (CRACM) is a precision technique for functional mapping of long-range neuronal projections between anatomically and/or genetically identified groups of neurons. Here, we describe how to utilize CRACM to map auditory brainstem connections, including the use of a red-shifted opsin, ChrimsonR.

The preparation and exfoliation of CaCuSi4O10 and BaCuSi4O10 are described. Upon stirring in hot water, CaCuSi4O10 spontaneously exfoliates into monolayers, whereas BaCuSi4O10 requires ultrasonication in organic solvents. Near infrared (NIR) imaging illustrates the NIR emission properties of these materials, and aqueous dispersions of these nanomaterials are useful for solution processing.

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

FAQs
The filters separate visual information by color channel, so each eye receives a different component of a paired image. When those images are slightly offset, the visual system can compare their locations and use the resulting binocular disparity as a cue to depth. This makes the goggles useful for examining how the brain combines signals that are not identical across the two eyes.
Binocular disparity provides the spatial difference needed for stereopsis, the perception of depth from comparing the two eyes’ views. With Red Blue Goggles, the color-separated images preserve this offset while directing different information toward each eye. Changing or observing the offset therefore helps researchers study how differences between retinal images contribute to three-dimensional perception.
They can present differing visual information to the two eyes, creating conditions in which the signals compete rather than combine smoothly. Binocular rivalry refers to alternating dominance between incompatible inputs, whereas interocular suppression describes reduced influence from one eye’s information. The goggles provide a controlled way to investigate how the visual system selects, limits, or integrates competing signals.
An experiment requires paired images or visual patterns prepared in separate color channels, with the two components arranged so that each filter transmits its intended information. Slight positional differences can provide a disparity cue, while more conflicting content can probe competition between the eyes. The viewing setup should therefore match the visual question, whether it concerns depth, integration, or suppression.
In neuroscience, these goggles support investigations of stereopsis and the processing of binocular information in the visual cortex. They also allow researchers to examine binocular rivalry, interocular suppression, and the neural integration of signals from both eyes. Because the same device can present separated or offset image components, it connects controlled visual stimulation with questions about perceptual and cortical processing.
They can be used in demonstrations and experiments that examine whether information from the two eyes is combined effectively. This is relevant to amblyopia, depth perception, and broader questions about binocular integration. Observing how a person experiences color-separated, offset images can help relate perceptual outcomes to the balance and coordination of signals arriving from both eyes.
