Sensory hairs are a commonly seen sensory system in the natural world. A wide variety of animal species can use these sensory hairs for a number of important behavioral tasks. This thesis focuses on a specific type of sensory hairs, the vibrissae (whiskers), in two species of animals, the rat and harbor seal. The study of these particular species is important because, while the structure their vibrissal systems are fundamentally similar, their primary sensory functions are thought to be different. The primary goal of this work is to determine how the morphology of an animal's vibrissal array determines its functional abilities. The rat vibrissal system is traditionally studied in the context of direct tactile sensing. The rat brushes its whiskers against objects in order to extract their size, shape, texture, and location. The seal vibrissal system is traditionally studied in the context of flow sensing. The seal uses its whiskers to hunt by sensing the trail of flow disturbances left by swimming fish. Through the study of these two species we hope to determine any secondary functionalities of their arrays as well as assess how the shapes of their arrays dictates how the array is used.

520 $a Sensory hairs are a commonly seen sensory system in the natural world. A wide variety of animal species can use these sensory hairs for a number of important behavioral tasks. This thesis focuses on a specific type of sensory hairs, the vibrissae (whiskers), in two species of animals, the rat and harbor seal. The study of these particular species is important because, while the structure their vibrissal systems are fundamentally similar, their primary sensory functions are thought to be different. The primary goal of this work is to determine how the morphology of an animal's vibrissal array determines its functional abilities. The rat vibrissal system is traditionally studied in the context of direct tactile sensing. The rat brushes its whiskers against objects in order to extract their size, shape, texture, and location. The seal vibrissal system is traditionally studied in the context of flow sensing. The seal uses its whiskers to hunt by sensing the trail of flow disturbances left by swimming fish. Through the study of these two species we hope to determine any secondary functionalities of their arrays as well as assess how the shapes of their arrays dictates how the array is used.
520 $a The first two studies presented in this thesis assess the ability of the rat to use its whisker system to sense airflow. In the first study (Chapter 2), we investigate what mechanical signals are transmitted through isolated rat whiskers by airflow. In this study we find that the whisker can measure the direction and speed of airflow and that it vibrates at frequencies related to the whisker's resonant modes. The second study (Chapter 3) determines the extent to which the rat makes use of the airflow information measured by the vibrissal system during a behavioral task. In this experiment we trained a group of rats to localize one of five wind sources. Following vibrissal removal, decrements in the rat's ability to locate the source of the flow were observed.
520 $a The third study (Chapter 4) presented in thesis defines a standard procedure for the measurement of the morphology of a whisker array. Using this procedure, the morphology of the harbor seal is measured and general trends within the array are presented. By using this procedure to measure the vibrissal arrays of many different animals, cross species comparisons can be completed. These comparisons will be vital in suggesting how the morphology of an array dictates its functional specialization.
520 $a The fourth study (Chapter 5) presented in this thesis uses the morphology measured in Chapter 4 to create a morphologically accurate seal whisker sensor. This chapter explains the process of designing and manufacturing the mystacial pad and whisker sensors. It also presents designs for the data acquisition circuitry and preliminary signals measured from whisker sensors. The chapter primarily serves as a guide for a future student to replicate the work that I have done as well as continue on with the completion of a full sensor array.
