Russo ([email protected]) Running head: Training in congenital amusia 2 Abstract Congenital amusia is a condition in which an individual suffers from a deficit of musical pitch perception and production. Individuals suffering from congenital amusia generally tend to abstain from musical activities. Here we present the unique case of Tim Falconer, a self- described musicophile who also suffers from congenital amusia. We describe and assess Tim’s attempts to train himself out of amusia through a self-imposed 18-month program of formal vocal training and practice. We tested Tim with respect to music perception and vocal production across seven sessions including pre-training and post-training assessments. We also obtained diffusion-weighted images of his brain to assess connectivity between auditory and motor planning areas via the arcuate fasciculus. -

ORIGINAL R Right Arcuate Fasciculus ESEARCH Abnormality in Chronic Fatigue n Syndrome1 NEURORADIOLOGY Michael M. Zeineh, MD, PhD Purpose: To identify whether patients with chronic fatigue syndrome James Kang, MD (CFS) have differences in gross brain structure, micro- Scott W. Atlas, MD scopic structure, or brain perfusion that may explain their Mira M. Raman, MS symptoms. Allan L. Reiss, MD Jane L. Norris, PA Materials and Fifteen patients with CFS were identified by means of Ian Valencia, BS Methods: retrospective review with an institutional review board– Jose G. Montoya, MD approved waiver of consent and waiver of authorization. Fourteen age- and sex-matched control subjects provided informed consent in accordance with the institutional review board and HIPAA. All subjects underwent 3.0-T volumetric T1-weighted magnetic resonance (MR) imag- ing, with two diffusion-tensor imaging (DTI) acquisitions and arterial spin labeling (ASL). Open source software was used to segment supratentorial gray and white matter and cerebrospinal fluid to compare gray and white matter volumes and cortical thickness. DTI data were processed with automated fiber quantification, which was used to compare piecewise fractional anisotropy (FA) along 20 tracks. For the volumetric analysis, a regression was per- formed to account for differences in age, handedness, and total intracranial volume, and for the DTI, FA was com- pared piecewise along tracks by using an unpaired t test. The open source software segmentation was used to com- pare cerebral blood flow as measured with ASL. -

A Comparison of Preoperative Transcranial Magnetic Stimulation and Intraoperative Direct Cortex Stimulation
CLINICAL ARTICLE J Neurosurg 134:1409–1418, 2021 Incidence and linguistic quality of speech errors: a comparison of preoperative transcranial magnetic stimulation and intraoperative direct cortex stimulation Ina Bährend, MD,1 Max R. Muench,1 Heike Schneider,1 Rabih Moshourab, MD,2 Felix R. Dreyer, MD,3 Peter Vajkoczy, MD,1 Thomas Picht, MD,1 and Katharina Faust, MD1 Departments of 1Neurosurgery and 2Anesthesiology, Charité, Universitätsmedizin Berlin; and 3Brain Language Laboratory, Freie Universität Berlin, Germany OBJECTIVE Given the interindividual variance of functional language anatomy, risk prediction based merely on ana- tomical data is insufficient in language area–related brain tumor surgery, suggesting the need for direct cortical and subcortical mapping during awake surgery. Reliable, noninvasive preoperative methods of language localization hold the potential for reducing the necessity for awake procedures and may improve patient counseling and surgical planning. Repetitive navigated transcranial magnetic stimulation (rnTMS) is an evolving tool for localizing language-eloquent areas. The aim of this study was to investigate the reliability of rnTMS in locating cortical language sites. METHODS Twenty-five patients with brain tumors in speech-related areas were prospectively evaluated with preopera- tive rnTMS (5 Hz, train of five, average 105% resting motor threshold) and navigated direct cortical stimulation (DCS; bipolar, 50 Hz, 6–8 mA, 200-μsec pulse width) during awake surgeries employing a picture-naming task. Positive and negative stimulation spots within the craniotomy were documented in the same MRI data set. TMS and DCS language- positive areas were compared with regard to their spatial overlap, their allocation in a cortical parcellation system, and their linguistic qualities. -

Methods developed at Boston University (Tourville & Guenther, 2003), Brigham and Women’s Hospital (McCarley & Shenton, 2008), Stanford (Allan Reiss lab), the University of Maryland (Buchanan et al., 2004), and the University of Toyoma (Zhou et al., 2007) were also consulted. The development of the protocol was also guided by the Ono, Kubik, and Abernathy (1990), Duvernoy (1999), and Mai, Paxinos, and Voss (Mai et al., 2008) neuroanatomical atlases. -

Received: 9 November 2020; Accepted: 2 December 2020; Published: 8 December 2020 Abstract: Autism Spectrum Disorder (ASD) is an early neurodevelopmental disorder that involves deficits in interpersonal communication, social interaction, and repetitive behaviors. Although ASD pathophysiology is still uncertain, alterations in the abnormal development of the frontal lobe, limbic areas, and putamen generate an imbalance between inhibition and excitation of neuronal activity. Interestingly, recent findings suggest that a disruption in neuronal connectivity is associated with neural alterations in white matter production and myelination in diverse brain regions of patients with ASD. This review is aimed to summarize the most recent evidence that supports the notion that abnormalities in the oligodendrocyte generation and axonal myelination in specific brain regions are involved in the pathophysiology of ASD. Fundamental molecular mediators of these pathological processes are also examined. Determining the role of alterations in oligodendrogenesis and myelination is a fundamental step to understand the pathophysiology of ASD and identify possible therapeutic targets. -
