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...

A novel vocal fold bioreactor capable of delivering physiologically relevant, vibratory stimulation to cultured cells is constructed and characterized. This dynamic culture device, when combined with a fibrous poly(ε-caprolactone) scaffold, creates a vocal fold-mimetic environment that modulates the behaviors of mesenchymal stem cells.

As manual dexterity is a prerogative mainly of primates, behavioral tasks have been developed in macaque monkeys. Four reach and grasp prehension tasks, measuring hand manipulation ability and force, allow to establish functional recovery after a lesion of the central nervous system and to test the effect of a treatment.

Voice disorders are debilitating in aging and Parkinson disease. The ultrasonic vocalizations of rats, also affected by these conditions, can be used to study these voice disorders, their neural substrates, and the nature of functional recovery with behavioral intervention.
FAQs
Researchers examine characteristics such as call structure and timing, then compare them with the caller’s social context, audience, and surrounding conditions. These patterns can indicate whether a signal relates to individual identity, social relationships, threats, reproduction, or emotional states. Acoustic analysis therefore connects measurable sound properties with the behavioral information that group members may receive.
Call production depends on coordinated control of breathing, the vocal folds, and the vocal tract. Changes across these components shape the sounds that monkeys and apes produce, while species-specific control contributes to differences in call structure. Studying this coordination helps behavioral researchers connect observable vocal signals with the biological processes that generate them.
The same general communication system can vary according to who is nearby and what social situation is occurring. Call timing and structure may shift with audience, relationships, environmental threats, or reproductive and emotional conditions. Examining these variations allows researchers to assess whether signals are adjusted to particular listeners and circumstances rather than produced independently of social context.
A basic investigation combines observations of calling behavior with analysis of acoustic features and the responses of nearby group members. Researchers relate when and how a call occurs to social circumstances, environmental threats, or other relevant conditions, then examine how listeners respond. This workflow helps distinguish patterns in signal production from patterns in audience behavior.
Patterns of calling and listener response can reveal how individuals recognize one another, maintain or reflect social relationships, and coordinate group activities. When researchers compare signals with the behavior of nearby primates, they can investigate how communication relates to social organization and cognition. These findings provide behavioral evidence about how information is processed within primate groups.
Comparing call structure, timing, calling behavior, and responses across social or environmental conditions helps researchers examine how communication systems function in different habitats. Such analyses can show how primates respond to threats and coordinate activities while adapting communication to surrounding conditions. They also provide a basis for studying evolutionary change in signaling systems.
