We demonstrate the use of the gene gun to introduce fluorescent dyes, such as DiI, into neurons in brain slices from rodents and non-human primates of different ages. In this particular case, we use adult mice (3-6 months old) and adult cynomologus monkeys (9-15 years old). This technique, originally described by the laboratory of Dr. Lichtman (Gan et al., 2000), is well suited for the study of dendritic branching and dendritic spine morphology and can be combined with traditional...

The anatomical organization of the primate brain can provide important insights into normal and pathological conditions in humans. Unbiased stereology is a method for accurately and efficiently estimating the total neuron number (or other cell type) in a given reference space1.
FAQs
Neural signaling across interconnected regions allows the primate brain to combine sensory information with movement, learning, social behavior, and decisions. Rather than attributing a complex behavior to one structure, researchers examine coordinated activity among the expanded cerebral cortex, specialized sensory areas, and prefrontal networks. This systems-level view helps link circuit organization to flexible cognition and behavior.
Prefrontal networks integrate information and regulate behavior, making them especially relevant to flexible decision-making. Their importance lies in coordination: activity in these networks can be studied alongside sensory and other cortical regions rather than in isolation. This approach helps neuroscientists investigate how neural circuits support behavioral regulation and why primate cognition is a useful model for human neuroscience.
Specialized sensory areas organize neural contributions to perception and connect sensory processing with broader circuit activity. Examining these areas together with the cerebral cortex and prefrontal networks allows researchers to ask how information becomes integrated into behavior, rather than treating perception as an isolated function. This perspective supports studies of coordinated neural signaling in primate neuroscience.
Researchers combine neuroanatomy, electrophysiology, and brain imaging to study the primate brain from complementary perspectives. Neuroanatomy addresses organization, electrophysiology examines neuronal activity, and imaging helps relate brain activity to larger-scale function. Used together, these approaches can connect neural circuits with cognition and behavior, strengthening interpretations that no single measurement could provide alone.
These studies can link the organization and activity of neural circuits to observable cognition and behavior. Depending on the approach, investigators may characterize anatomical structure, neuronal signaling, or patterns of brain activity. The combined evidence helps explain how perception, movement, learning, social behavior, and decision-making depend on coordinated neural systems.
Studying the primate brain supports comparative neuroscience by connecting brain organization with the evolution of complex mental abilities. It also provides a framework for investigating neurological and psychiatric disorders through relationships among neural circuits, cognition, and behavior. These applications make primate research relevant both to understanding human neuroscience and to examining the biological basis of behavior.
