  • The Nerve Lesion in the Carpal Tunnel Syndrome
    J Neurol Neurosurg Psychiatry: first published as 10.1136/jnnp.39.7.615 on 1 July 1976. Downloaded from Journal of Neurology, Neurosurgery, and Psychiatry, 1976, 39, 615-626 The nerve lesion in the carpal tunnel syndrome SYDNEY SUNDERLAND From the Department of Experimental Neurology, University of Melbourne, Parkville, Victoria, Australia SYNOPSIS The relative roles of pressure deformation and ischaemia in the production of compres- sion nerve lesions remain a controversial issue. This paper concerns the genesis of the structural changes which follow compression of the median nerve in the carpal tunnel. The initial lesion is an intrafunicular anoxia caused by obstruction to the venous return from the funiculi as the result of increased pressure in the tunnel. This leads to intrafunicular oedema and an increase in intrafunicular pressure which imperil and finally destroy nerve fibres by impairing their blood supply and by compression. The final outcome is the fibrous tissue replacement of the contents of the funiculi. Protected by copyright. In 1862 Waller described the motor, vasomotor, (Gasser, 1935; Allen, 1938; Bentley and Schlapp, and sensory changes which followed the com- 1943; Richards, 1951; Moldaver, 1954; Gelfan pression of nerves in his own arm.

It has been shown that these biological tissues are significantly rate-dependent; hence, their material properties should be determined with respect to the range of deformation rate they experience. In this paper, a validated finite element human head model is used to investigate the biomechanics of the head in impact and blast, leading to traumatic brain injuries (TBI). We simulate the head under various directions and velocities of impacts, as well as helmeted and unhelmeted head under blast shock waves. It is demonstrated that the strain rates for the brain 1 are in the range of 36 to 241 s− , approximately 1.9 and 0.86 times the resulting head acceleration under impacts and blast scenarios, respectively. The skull was found to experience a rate in the range 1 of 14 to 182 s− , approximately 0.7 and 0.43 times the head acceleration corresponding to impact and blast cases.

  • Deconstructing Spinal Interneurons, One Cell Type at a Time Mariano Ignacio Gabitto
    Deconstructing spinal interneurons, one cell type at a time Mariano Ignacio Gabitto Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee of the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2016 © 2016 Mariano Ignacio Gabitto All rights reserved ABSTRACT Deconstructing spinal interneurons, one cell type at a time Mariano Ignacio Gabitto Abstract Documenting the extent of cellular diversity is a critical step in defining the functional organization of the nervous system. In this context, we sought to develop statistical methods capable of revealing underlying cellular diversity given incomplete data sampling - a common problem in biological systems, where complete descriptions of cellular characteristics are rarely available. We devised a sparse Bayesian framework that infers cell type diversity from partial or incomplete transcription factor expression data. This framework appropriately handles estimation uncertainty, can incorporate multiple cellular characteristics, and can be used to optimize experimental design. We applied this framework to characterize a cardinal inhibitory population in the spinal cord. Animals generate movement by engaging spinal circuits that direct precise sequences of muscle contraction, but the identity and organizational logic of local interneurons that lie at the core of these circuits remain unresolved. By using our Sparse Bayesian approach, we showed that V1 interneurons, a major inhibitory population that controls motor output, fractionate into diverse subsets on the basis of the expression of nineteen transcription factors. Transcriptionally defined subsets exhibit highly structured spatial distributions with mediolateral and dorsoventral positional biases. These distinctions in settling position are largely predictive of patterns of input from sensory and motor neurons, arguing that settling position is a determinant of inhibitory microcircuit organization.

  • The Nervous System
    The Nervous System • A network of billions of nerve cells linked together in a highly organized fashion to form the rapid control center of the body. • Functions include: – Integrating center for homeostasis, movement, and almost all other body functions. – The mysterious source of those traits that we think of as setting humans apart from animals Basic Functions of the Nervous System 1. Sensation • Monitors changes/events occurring in and outside the body. Such changes are known as stimuli and the cells that monitor them are receptors. 2. Integration • The parallel processing and interpretation of sensory information to determine the appropriate response 3. Reaction • Motor output. – The activation of muscles or glands (typically via the release of neurotransmitters (NTs)) Organization of the Nervous System • 2 big initial divisions: 1. Central Nervous System • The brain + the spinal cord – The center of integration and control 2. Peripheral Nervous System • The nervous system outside of the brain and spinal cord • Consists of: – 31 Spinal nerves » Carry info to and from the spinal cord – 12 Cranial nerves » Carry info to and from the brain Peripheral Nervous System • Responsible for communication btwn the CNS and the rest of the body. • Can be divided into: – Sensory Division • Afferent division – Conducts impulses from receptors to the CNS – Informs the CNS of the state of the body interior and exterior – Sensory nerve fibers can be somatic (from skin, skeletal muscles or joints) or visceral (from organs w/i the ventral body cavity) – Motor Division • Efferent division – Conducts impulses from CNS to effectors (muscles/glands) – Motor nerve fibers Motor Efferent Division • Can be divided further: – Somatic nervous system • VOLUNTARY (generally) • Somatic nerve fibers that conduct impulses from the CNS to skeletal muscles – Autonomic nervous system • INVOLUNTARY (generally) • Conducts impulses from the CNS to smooth muscle, cardiac muscle, and glands.

  • Spinal Cord Organization
    Lecture 4 Spinal Cord Organization The spinal cord . Afferent tract • connects with spinal nerves, through afferent BRAIN neuron & efferent axons in spinal roots; reflex receptor interneuron • communicates with the brain, by means of cell ascending and descending pathways that body form tracts in spinal white matter; and white matter muscle • gives rise to spinal reflexes, pre-determined gray matter Efferent neuron by interneuronal circuits. Spinal Cord Section Gross anatomy of the spinal cord: The spinal cord is a cylinder of CNS. The spinal cord exhibits subtle cervical and lumbar (lumbosacral) enlargements produced by extra neurons in segments that innervate limbs. The region of spinal cord caudal to the lumbar enlargement is conus medullaris. Caudal to this, a terminal filament of (nonfunctional) glial tissue extends into the tail. terminal filament lumbar enlargement conus medullaris cervical enlargement A spinal cord segment = a portion of spinal cord that spinal ganglion gives rise to a pair (right & left) of spinal nerves. Each spinal dorsal nerve is attached to the spinal cord by means of dorsal and spinal ventral roots composed of rootlets. Spinal segments, spinal root (rootlets) nerve roots, and spinal nerves are all identified numerically by th region, e.g., 6 cervical (C6) spinal segment. ventral Sacral and caudal spinal roots (surrounding the conus root medullaris and terminal filament and streaming caudally to (rootlets) reach corresponding intervertebral foramina) collectively constitute the cauda equina. Both the spinal cord (CNS) and spinal roots (PNS) are enveloped by meninges within the vertebral canal. Spinal nerves (which are formed in intervertebral foramina) are covered by connective tissue (epineurium, perineurium, & endoneurium) rather than meninges.

Innervation • Start another table. Write that for the motor fibers: • The corticospinal tract fibers innervate the body via spinal motor neurons. - Specify that the lateral CST innervates distal musculature for fine motor movements - Whereas the anterior CST innervates proximal musculature for gross motor movements. • The corticobulbar fibers (aka corticonuclear fibers) innervate the face via the CNs. Projections • Now, demarcate the internal capsule deep within the cerebrum – the motor fibers consolidate here before entering the ipsilateral cerebral peduncle in the midbrain. • Next, draw the twisting descent of each fiber group through the subcortical white matter. • Show that the facial fibers [RED] emerge from the lateral convexity, descend medially and, generally, decussate to synapse on different cranial nerve nuclei throughout their descent. • Then, show that the leg fibers [GREEN] emerge paracentrally, descend laterally through the brainstem into the ipsilateral medullary pyramid. • Show that the arm fibers [BLUE] emerge from the upper convexity, descend in between the facial and leg fibers, medial to the leg fibers through the brainstem into the ipsilateral medullary pyramid.
