  • Electromagnetic Field and TGF-Β Enhance the Compensatory
    www.nature.com/scientificreports OPEN Electromagnetic feld and TGF‑β enhance the compensatory plasticity after sensory nerve injury in cockroach Periplaneta americana Milena Jankowska1, Angelika Klimek1, Chiara Valsecchi2, Maria Stankiewicz1, Joanna Wyszkowska1* & Justyna Rogalska1 Recovery of function after sensory nerves injury involves compensatory plasticity, which can be observed in invertebrates. The aim of the study was the evaluation of compensatory plasticity in the cockroach (Periplaneta americana) nervous system after the sensory nerve injury and assessment of the efect of electromagnetic feld exposure (EMF, 50 Hz, 7 mT) and TGF‑β on this process. The bioelectrical activities of nerves (pre‑and post‑synaptic parts of the sensory path) were recorded under wind stimulation of the cerci before and after right cercus ablation and in insects exposed to EMF and treated with TGF‑β. Ablation of the right cercus caused an increase of activity of the left presynaptic part of the sensory path. Exposure to EMF and TGF‑β induced an increase of activity in both parts of the sensory path. This suggests strengthening efects of EMF and TGF‑β on the insect ability to recognize stimuli after one cercus ablation. Data from locomotor tests proved electrophysiological results. The takeover of the function of one cercus by the second one proves the existence of compensatory plasticity in the cockroach escape system, which makes it a good model for studying compensatory plasticity. We recommend further research on EMF as a useful factor in neurorehabilitation. Injuries in the nervous system caused by acute trauma, neurodegenerative diseases or even old age are hard to reverse and represent an enormous challenge for modern medicine.

CHAPTER 2 Sensory change following motor learning { k { { Andrew A. G. Mattar , Sazzad M. Nasir , Mohammad Darainy , and { } David J. Ostry , ,* { Department of Psychology, McGill University, Montréal, Québec, Canada { Shahed University, Tehran, Iran } Haskins Laboratories, New Haven, Connecticut, USA k The Roxelyn and Richard Pepper Department of Communication Sciences and Disorders, Northwestern University, Evanston, Illinois, USA Abstract: Here we describe two studies linking perceptual change with motor learning. In the first, we document persistent changes in somatosensory perception that occur following force field learning. Subjects learned to control a robotic device that applied forces to the hand during arm movements. This led to a change in the sensed position of the limb that lasted at least 24 h. Control experiments revealed that the sensory change depended on motor learning. In the second study, we describe changes in the perception of speech sounds that occur following speech motor learning. Subjects adapted control of speech movements to compensate for loads applied to the jaw by a robot. Perception of speech sounds was measured before and after motor learning. Adapted subjects showed a consistent shift in perception. In contrast, no consistent shift was seen in control subjects and subjects that did not adapt to the load. These studies suggest that motor learning changes both sensory and motor function. Keywords: motor learning; sensory plasticity; arm movements; proprioception; speech motor control; auditory perception. Introduction the human motor system and, likewise, to skill acquisition in the adult nervous system.

  • Cochlear Implant Guide
    Cochlear Implant Guide Ear & Hearing Center at Texas Children’s Hospital® Dear Families, Welcome to the Cochlear Implant Program at Texas Children’s Hospital! Our goal is to provide comprehensive, specialized care for children with severe hearing loss, and help them achieve the best possible communication outcomes. Since our program started in 2001, we have performed more than 700 implants. Your child may be a candidate for a cochlear implant in one or both ears. Cochlear implants, or CIs, are innovative devices which can directly stimulate the auditory nerve and provide access to sound in children with severe or profound hearing loss. The decision about whether to recommend a CI is highly individualized, and requires the input of specialists in multiple areas, including Otolaryngology, Audiology, Speech Pathology, and Neuropsychology, among others. These specialists make up the members of the Cochlear Implant Team. They work in close collaboration to determine who is a candidate for a CI, perform the implantation surgery, and help patients through the rehabilitation afterwards. This guide will help you understand the entire process, who may be considered a CI candidate, the basics of how the device works, how the surgery is done, and the necessary rehabilitation to achieve a successful outcome. Thank you for the opportunity to help your family through this journey. All of our team members are dedicated to helping children with hearing loss achieve their full potential. If you have any questions or concerns, please do not hesitate to contact us. Sincerely, The Cochlear Implant Team at Texas Children’s Hospital Table of Contents 1.

Peripheral in this context refers to (cochlea) & balance a system that is outside of the central nervous system (brain and (vestibular). brainstem). The peripheral vestibular system sends information to the brain and brainstem. The vestibular system in each ear consists of a complex series of passageways and chambers within the bony skull. Within these ARTICLE passageways are tubes (semicircular canals), and sacs (a utricle and saccule), filled with a fluid called endolymph. Around the outside of the tubes and sacs is a different fluid called perilymph. Both of these fluids are of precise chemical compositions, and they are different. The mechanism that regulates the amount and composition of these fluids is 04 important to the proper functioning of the inner ear. Each of the semicircular canals is located in a different spatial plane. They are located at right angles to each other and to those in the ear on the opposite side of the head.

  • Sensory Overamplification in Layer 5 Auditory Corticofugal Projection Neurons Following Cochlear Nerve Synaptic Damage
    Corrected: Publisher correction ARTICLE DOI: 10.1038/s41467-018-04852-y OPEN Sensory overamplification in layer 5 auditory corticofugal projection neurons following cochlear nerve synaptic damage Meenakshi M. Asokan1,2, Ross S. Williamson1,3, Kenneth E. Hancock1,3 & Daniel B. Polley1,2,3 Layer 5 (L5) cortical projection neurons innervate far-ranging brain areas to coordinate integrative sensory processing and adaptive behaviors. Here, we characterize a plasticity in 1234567890():,; L5 auditory cortex (ACtx) neurons that innervate the inferior colliculus (IC), thalamus, lateral amygdala and striatum. We track daily changes in sound processing using chronic widefield calcium imaging of L5 axon terminals on the dorsal cap of the IC in awake, adult mice. Sound level growth functions at the level of the auditory nerve and corticocollicular axon terminals are both strongly depressed hours after noise-induced damage of cochlear afferent synapses. Corticocollicular response gain rebounded above baseline levels by the following day and remained elevated for several weeks despite a persistent reduction in auditory nerve input. Sustained potentiation of excitatory ACtx projection neurons that innervate multiple limbic and subcortical auditory centers may underlie hyperexcitability and aberrant functional coupling of distributed brain networks in tinnitus and hyperacusis. 1 Eaton-Peabody Laboratories, Massachusetts Eye and Ear Infirmary, Boston, MA 02114, USA. 2 Division of Medical Sciences, Harvard University, Boston, MA 02114, USA. 3 Department of Otolaryngology, Harvard Medical School, Boston, MA 02114, USA.

  • Audiometric Findings with Voluntary Tensor Tympani Contraction Brandon Wickens1 , Duncan Floyd2 and Manohar Bance3*
    Wickens et al. Journal of Otolaryngology - Head and Neck Surgery (2017) 46:2 DOI 10.1186/s40463-016-0182-y ORIGINALRESEARCHARTICLE Open Access Audiometric findings with voluntary tensor tympani contraction Brandon Wickens1 , Duncan Floyd2 and Manohar Bance3* Abstract Background: Tensor tympani contraction may have a "signature" audiogram. This study demonstrates audiometric findings during voluntary tensor tympani contraction. Methods: Five volunteers possessing the ability to voluntarily contract their tensor tympani muscles were identified and enrolled. Tensor tympani contraction was confirmed with characteristic tympanometry findings. Study subjects underwent conventional audiometry. Air conduction and bone conduction threshold testing was performed with and without voluntary tensor tympani contraction. Main outcome measure: Changes in air conduction and bone conduction thresholds during voluntary tensor tympani contraction. Results: Audiometric results demonstrate a low frequency mixed hearing loss resulting from tensor tympani contraction. Specifically, at 250 Hz, air conduction thresholds increased by 22 dB and bone conduction thresholds increased by 10 dB. Conclusions: Previous research has demonstrated a low frequency conductive hearing loss in the setting of tensor tympanic contraction. This is the first study to demonstrate a low frequency mixed hearing loss associated with tensor tympani contraction. This finding may aid in the diagnosis of disorders resulting from abnormal tensor tympani function. Tensor tympani contraction
