2025
A wide-field Fourier-transform microscope, based on a compact and ultra-stable birefringent interferometer, allows the parallel acquisition of spectra for all pixels of a 2D detector. The time-domain approach enables the disentanglement of photoluminescence and Raman signals, and allows rapid Raman mapping (~5 ms/pixel) with ~1-µm spatial and 23-cm-1 spectral resolution.

This protocol describes the synthesis of biofunctionalized Prussian blue nanoparticles and their use as multimodal, molecular imaging agents. The nanoparticles have a core-shell design where gadolinium or manganese ions within the nanoparticle core generate MRI contrast. The biofunctional shell contains fluorophores for fluorescence imaging and targeting ligands for molecular targeting.
FAQs
It compares the timing, intensity, and reliability of incoming cues. Signals that arrive together and provide consistent information are more likely to support a unified interpretation, whereas differences can reveal that the cues do not match. This comparison helps organisms select responses that fit the available evidence instead of relying on one sensory channel alone.
Agreement gives the nervous system converging evidence about an event or situation. When visual, auditory, olfactory, or tactile cues point toward the same interpretation, the resulting perception can support more effective action. In behavior, this principle helps explain why communication and environmental responses may become more reliable when information is available through multiple sensory channels.
Conflicting cues require the nervous system to evaluate which information is more dependable and how closely the signals correspond in time and intensity. Rather than treating every cue as equally informative, the organism can use these differences to resolve the mismatch. Such conflicts are useful for studying how perception, attention, and decision-making respond to uncertainty.
Research commonly examines communication, social interaction, attention, decision-making, and responses to environmental change. These processes depend on how organisms interpret information from more than one sensory source and convert it into behavior. Studying them together can show whether combined cues alter perception, guide choices, strengthen social responses, or help an organism adapt when conditions change.
A behavioral study can present information through two or more sensory channels and examine how participants or animals respond when the cues agree or differ. Researchers can compare responses under changes in timing, intensity, or cue reliability. This design reveals whether combined information improves behavior, produces conflict, or changes attention and decision-making.
These studies can clarify how sensory information is integrated before it shapes behavior. Comparing responses to agreement and conflict helps researchers identify the importance of timing, intensity, and reliability in perceptual decisions. The findings contribute to models of perception, communication, and adaptive action, while also providing behavioral evidence about the neural basis of social and environmental responses.
