This protocol describes the steps and data analysis required to successfully perform optogenetic functional magnetic resonance imaging (ofMRI). ofMRI is a novel technique that combines high-field fMRI readout with optogenetic stimulation, allowing for cell type-specific mapping of functional neural circuits and their dynamics across the whole living brain.

Preoperational Thought IV: Numbers

2026
Piaget’s preoperational stage, from about ages 2 to 7, is characterized by rapid growth in symbolic thinking. Children increasingly use words, images, and objects to represent ideas, although their reasoning remains largely intuitive. During this period, number sense develops from memorized counting toward an understanding of quantity and basic arithmetic.Counting and CardinalityChildren younger than age 3 may recite number words without fully understanding their numerical meaning. During the...

Preoperational Thought I: The Symbolic Function

Jean Piaget’s preoperational stage of cognitive development spans approximately ages 2 to 7. During this period, children increasingly think symbolically but are not yet able to perform logical mental operations consistently. Symbols are words, pictures, numbers, or objects that stand for something else. For example, the word "dog" can represent an entire category of animals, even when no dog is physically present. This ability allows children to mentally represent people, objects, and events...

Early detection of apoptosis may identify at-risk cell populations in a variety of diseases. Here we demonstrate a method to link an early apoptosis-detection protein (Annexin V) to a MRI-detectable iron oxide nanoparticle (SPIO). This method may be extended to other proteins of interest to generate MRI-detectable molecular imaging probes.
FAQs
The scan records signals from hydrogen nuclei after their alignment is altered by a strong magnetic field and radiofrequency pulses. These signals are processed into detailed images that distinguish disease from surrounding soft tissues and show relevant anatomical relationships. That information helps clinicians localize abnormalities more precisely before selecting or modifying an operative approach.
Multiplanar imaging shows anatomy from different spatial orientations rather than relying on a single viewing plane. This broader representation helps clinicians evaluate tumor extent, tissue planes, and relationships with nearby structures. In practice, surgeons can use the combined views to anticipate the location and boundaries of disease during treatment planning.
Because the examination uses a magnetic field and radiofrequency pulses rather than ionizing radiation, it provides detailed anatomical information through a different physical mechanism. This is relevant when clinicians need repeated or highly detailed soft-tissue assessment during planning. The resulting images can support decision-making while avoiding the radiation exposure associated with imaging methods that use ionizing radiation.
Clinicians assess the extent of disease and its relationship to surrounding anatomy, including tissue planes and possible vascular or neurological involvement. They also examine findings that could affect the planned procedure. This assessment converts detailed imaging into practical information about localization, anticipated technical challenges, and whether the surgical strategy may need adjustment.
Findings such as greater-than-expected tumor extent or involvement of nearby vascular or neurological structures may alter how clinicians plan the operation. The images help identify these relationships before surgery rather than discovering them only during the procedure. As a result, the team can anticipate technical difficulties and refine treatment planning around the patient’s anatomy.
The examination provides a shared anatomical reference for clinicians involved in treatment planning. Detailed views of disease location, extent, tissue planes, and nearby structures can improve communication about operative risks and technical considerations. By giving the multidisciplinary team a common set of findings to review, Preoperative MRI supports coordinated decisions before the operation begins.
