We describe a preclinical experimental method to evaluate metabolic neuromodulation induced by acute deep brain stimulation with in vivo FDG-PET. This manuscript includes all experimental steps, from stereotaxic surgery to the application of the stimulation treatment and the acquisition, processing, and analysis of PET images.

Classical multivariate pattern analysis predicts sensory stimuli a subject perceives from neural activity in the corresponding cortices (e.g. visual stimuli from activity in visual cortex). Here, we apply pattern analysis cross-modally and show that sound- and touch-implying visual stimuli can be predicted from activity in auditory and somatosensory cortices, respectively.

In this video, we will demonstrate how to record electrical activity from identified single neurons in a whole brain preparation, which preserves complex neural circuits. We use transgenic fish in which gonadotropin-releasing hormone (GnRH) neurons are genetically tagged with a fluorescent protein for identification in the intact brain preparation.

This protocol presents a method for creating a large unilateral craniotomy over the temporal and parietal regions of the mouse cerebral cortex. This is especially useful for real time imaging over an expansive area of a cortical hemisphere.
FAQs
Comparing brain activation patterns across conditions reveals which neural responses change with a behavior, task, or emotional state. A pattern may include both increased and decreased activity across regions, so the contrast can show how communication among neural circuits differs between situations. This approach helps connect observable behavior with organized changes in underlying neural activity.
Neural activity does not need to rise uniformly across the brain to support behavior. Networks can show coordinated increases in some regions and decreases in others as neurons communicate through electrical and chemical signals. Examining this balance helps researchers interpret a response as an organized circuit-level process rather than as a change in one isolated location.
Individual differences in brain activation patterns can be examined alongside differences in behavior, cognition, motivation, or motor responses. When patterns vary across people, the comparison may help clarify how neural circuits relate to behavioral variation. It can also provide context for investigating neurological or psychiatric disorders, without treating an activation pattern alone as a complete explanation.
Functional neuroimaging and electrophysiology are the measurement approaches identified for examining these patterns. They allow researchers to assess neural activity while studying particular behaviors, cognitive tasks, or emotional states. Applying these approaches across conditions or individuals makes it possible to compare organized changes in activity and relate those changes to the behavioral question under study.
Researchers examine neural activity during particular behaviors, cognitive tasks, or emotional states, then compare patterns across conditions or individuals. The key outcome is not merely whether activity changes, but how increases and decreases are organized across brain regions. This comparison supports interpretation of links between neural circuits and behavior while keeping the measured activity connected to a specific experimental context.
These patterns can be studied during learning, decision-making, perception, motivation, and motor responses. Researchers can ask whether different behavioral or cognitive conditions correspond to different organizations of activity across brain regions. The resulting comparisons help connect observed performance or responses with underlying neural circuits, adding a neural perspective to behavioral research.
In neurological and psychiatric research, comparing activation across conditions or individuals can reveal altered relationships between brain activity and behavior. Such comparisons may help identify how neural circuits are associated with a disorder-related behavioral profile. The value lies in examining patterns in context, rather than interpreting a single region or measurement without reference to the behavior being studied.
