Right-angle microprisms inserted into the mouse neocortex allows for deep imaging of multiple cortical layers with a viewpoint typically found in slice. One-millimeter microprisms offer a wide field-of-view (~900 μm) and spatial resolutions sufficient to resolve dendritic spines. We demonstrate layer V neuronal imaging and neocortical vascular imaging using microprisms.

Calcium signals play a key role in many cellular processes including gene expression, survival and differentiation. Here we demonstrate how to perform calcium imaging using Fura-2 AM. Calcium imaging is a valuable tool to study the regulation of intracellular calcium in real time and its regulation of signaling cascades.
FAQs
Several biological changes can contribute to this pattern. Atypical structural pathways may limit how efficiently cortical regions are linked, while altered white-matter integrity may affect the routes supporting communication. A separate or related change can appear as weaker functional coupling, meaning that regions show less coordinated activity. Distinguishing these possibilities helps researchers interpret the underlying mechanism.
Structural and functional findings describe related but nonidentical aspects of cortical organization. Diffusion MRI can be used to investigate the pathways connecting regions, whereas functional MRI and electroencephalography help examine coordinated activity. A person may therefore show evidence involving physical pathways, activity synchronization, or both. This distinction matters when researchers compare biological explanations across neurological and psychiatric conditions.
Information processing often depends on communication among multiple cortical regions rather than on one area acting alone. When coordination is reduced, researchers may examine whether this pattern helps explain difficulties with information integration, cognition, or perception. In medicine, that link provides a mechanistic research question for studying neurological and psychiatric disorders.
Researchers investigate cortical underconnectivity with diffusion MRI, functional MRI, and electroencephalography. Together, these approaches allow studies to examine different evidence relevant to communication between cortical regions, including structural pathways and patterns of coordinated activity. Using more than one method can help connect observations about anatomy, functional coupling, and electrical activity within a broader research assessment.
It has been investigated in autism and schizophrenia, as well as in other disorders involving cognition or perception. The research does not treat the pattern as relevant to only one diagnosis; instead, investigators examine whether altered cortical communication contributes to clinical features. This cross-condition perspective supports broader study of neurological and psychiatric mechanisms.
Researchers may use the pattern to guide biomarker development and to motivate more targeted diagnosis and treatment research. Its value lies in linking measurable brain features with questions about cognition, perception, or information integration. These studies can help clarify how altered cortical communication relates to disorders and can refine research directions for neurological and psychiatric medicine.
