Scott Center for Neuroscience, Mind and Behavior, Bowling Green State University, Bowling Green, OH 43403, USA bFalk Center for Molecular Therapeutics, Northwestern University Research Park, 1801 Maple Avenue, Suite 4306, Evanston, IL 60201, USA Received 4 April 2003; accepted 17 April 2003 Abstract Paul MacLean’s concept of epistemics—the neuroscientific study of subjective experience—requires animal brain research that can be related to predictions concerning the internal experiences of humans. Especially robust relationships come from studies of the emotional/ affective processes that arise from subcortical brain systems shared by all mammals. Recent affective neuroscience research has yielded the discovery of play- and tickle-induced ultrasonic vocalization patterns ( 50-kHz chirps) in rats may have more than a passing resemblance to primitive human laughter. In this paper, we summarize a dozen reasons for the working hypothesis that such rat vocalizations reflect a type of positive affect that may have evolutionary relations to the joyfulness of human childhood laughter commonly accompanying social play. The neurobiological nature of human laughter is discussed, and the relevance of such ludic processes for understanding clinical disorders such as attention deficit hyperactivity disorders (ADHD), addictive urges and mood imbalances are discussed.

Socrates proposed that tickle induced pleasure and pain. Others, including Darwin, have claimed that ticklish laughter is virtually the same as humorous laughter. The present study is the first to systematically examine facial behavior and self-reports of emotion in response to tickling. Using a within-subjects design, 84 subjects’ responses to being tickled were compared to their responses when experiencing a painful stimulus and their responses to comedy. Overall results for both self-report and facial action coding showed that the tickle condition elicited both pleasure and displeasure. Facial action during tickling included “Duchenne” smiles plus movements associated with negative emotions. Results suggest that tickle-induced smiling can be dissociated from positive affect. Tickle may be a type of complex reflex or fixed-action pattern. Facial Expressions 4 Facial Expressions, Smile Types, and Self-report during Humor, Tickle, and Pain: An Examination of Socrates’ Hypothesis Tickling and the smiling it induces, at first blush, seem like child’s play.

  • (1999). the Mystery of Ticklish Laughter
    American Scientist July-August 1999 v87 i4 p344(8) Page 1 The mystery of ticklish laughter. by Christine R. Harris Scientists are trying to find out why people laugh when they are tickled. The intriguing nature of tickling is made more complex by the fact that people almost always break into laughter when tickled by others but not when they tickle themselves. Psychologist G. Stanley Hall classified tickle into two types, namely, knismesis or light tickle and gargalesis or heavy tickle, thereby explaining in part why tickling does not always elicit laughter. One plausible theory suggests that tickle may be an evolutionary adaptation, evident as it is in the social interaction among primates. Thus, the discomfort and pleasure elicited by tickling might be adaptive and help a child develop skills that can be used in defense and combat. © COPYRIGHT 1999 Sigma Xi, The Scientific Research Here I would like to share some of the clues and curious Society possibilities emerging from my own work and that of others.

Tickling, a Technique for Inducing Positive Affect When Handling Rats. J. Vis. Exp. (135), e57190, doi:10.3791/57190 (2018). Abstract Handling small animals such as rats can lead to several adverse effects. These include the fear of humans, resistance to handling, increased injury risk for both the animals and the hands of their handlers, decreased animal welfare, and less valid research data. To minimize negative effects on experimental results and human-animal relationships, research animals are often habituated to being handled. However, the methods of habituation are highly variable and often of limited effectiveness. More potently, it is possible for humans to mimic aspects of the animals' playful rough-and-tumble behavior during handling.

    Seite 1 von 1 Leibniz Lecture – Prof. Dr. Michael Brecht Neurophysiology/Cellular Neuroscience Bernstein Center for Computational Neuroscience Berlin and Humboldt University Berlin Sex, Touch & Tickle - the Cortical Neurobiology of Physical Contact SAVE THE DATE 24th April 2018 th 26 April 2018 São Paulo - SP Rio de Janeiro - RJ FAPESP Auditorium Instituto D’Or R. Pio XI, 1500 - Alto da Lapa R. Diniz Cordeiro, 30 - Botafogo Abstract The cerebral cortex is the largest brain structure in mammalian brains. While we know much about cortical responses to controlled, experimenter imposed sensory stimuli, we have only limited understanding of cortical responses evoked by complex social interactions. In my lecture I will focus on response patterns evoked by social touch in somatosensory cortex in interacting rats. We find that social touch evokes stronger responses than object touch or free whisking. Moreover, we find prominent sex differences in responsiveness. We observe a modulation of cortical activity with estrus cycle in females, and in particular a modulation of fast-spiking interneurons by estrogens. The prominent sex differences are unexpected, since the somatosensory cortex is not anatomically sexually dimorphic. Recently, we confirmed the absence of anatomical sex differences in somatosensory cortex by an analysis of somatosensory representations of genitals. Despite the marked external sexual dimorphism of genitals, we observed a stunning similarity of the cortical maps representing the clitoris and penises, respectively. In the final part of my presentation I will discuss the involvement of somatosensory cortex in ticklishness. In these experiments we habituated rats to be tickled and found that animals respond to such stimulation with vocalizations.

  • Intervertebral Disk Disease
    THE PET HEALTH LIBRARY By Wendy C. Brooks, DVM, DipABVP Educational Director, VeterinaryPartner.com Intervertebral Disk Disease What is a Disk? Most people are aware that the backbone is not just one long, tubular bone. The backbone (or spine) is actually made of numerous smaller bones called vertebrae that house and protect the spinal cord. The numerous vertebrae that make up the spine allow for flexibility of the back. The vertebrae are connected by joints called intervertebral disks. The disk serves as a cushion between the vertebral bodies of the vertebrae. It consists of a fibrous outer shell (called the annulus fibrosus), a jelly-like interior (the nucleus pulposus), and cartilage caps on each side connecting it to the vertebral bones. Ligaments run below and above the discs, with the ligament above the discs being particularly rich in sensitive nerves. These ligaments are called the dorsal (above) and ventral (below) longitudinal ligaments. There are seven cervical (neck) vertebrae, 13 thoracic (chest) vertebrae, even lumbar (lower back) vertebrae, three sacral vertebrae (which are fused), and a variable number of tail vertebrae. Type I and Type II Disk Disease There are two types of disease that can afflict the intervertebral disk causing the disk to press painfully against the spinal cord: Hansen Type I Disk Disease and Hansen Type II Disk Disease. In Type I, the nucleus pulposus becomes calcified (mineralized). A wrong jump by the patient causes the rock-like disk material to shoot out of the annulus fibrosus. If the disk material shoots upward, it will press painfully on the ligament above and potentially cause compression of the spinal cord further above.
