The Russian Aphasia Test: The first comprehensive, quantitative, standardized, and computerized aphasia language battery in Russian
November 21, 2021
Maria Ivanova and colleagues publish their important work on the creation of a Russian Aphasia Test on par with its English counterparts.
Abstract: The lack of standardized language assessment tools in Russian impedes clinical work, evidence-based practice, and research in Russian-speaking clinical populations. To address this gap in the assessment of neurogenic language disorders, we developed and standardized a new comprehensive assessment instrument – the Russian Aphasia Test (RAT). The principal novelty of the RAT is that each subtest corresponds to a specific level of linguistic processing (phonological, lexical-semantic, syntactic, and discourse) in different domains: auditory comprehension, repetition, and oral production. In designing the test, we took into consideration various (psycho)linguistic factors known to influence language performance, as well as specific properties of Russian

New papers from our lab:
August 12, 2021
We are excited to share two recent publications with our amazing colleagues from the Center for Language, Imaging, Mind & Brain at the VA Northern California Health Care System, Martinez, CA.
In the first paper published in NeurImage: Clinical we examined a rare case of tactile agnosia, in which a small white matter lesion in the left hemisphere adjacent to the corpus callosum, a large white matter tract connecting the two hemispheres, selectively impaired the person’s ability to name letters and numbers presented to the ipsilesional, left hand. This case highlights the significant impact that a focal white matter lesion can have on higher-level cognition, specifically the integration of verbal and tactile information.
The second paper published in Frontiers in Neurology explored the time course for recovery of auditory comprehension abilities following stroke. The study demonstrated that the posterior left middle temporal gyrus plays a crucial role in recovery of both word and sentence level comprehension. Overall, the observed patterns underscore that spontaneous recovery of auditory comprehension can continue well beyond the first year post-stroke.
New paper: “Gender bias in academia: A lifetime problem that needs solutions”
July 7, 2021
Drs. Nina F. Dronkers and Maria V. Ivanova contributed to a paper “Gender bias in academia: A lifetime problem that needs solutions” that was just published in Neuron. In this article an international team of scientists lead by Dr. Anais Llorens, University of California, Berkeley, CA and Dr. Athina Tzovara, University of Bern, Bern, Switzerland reviewed empirical evidence demonstrating pervasive gender bias throughout all stages and venues of academic life. The paper provides a comprehensive overview of the current issues and proposes concrete solutions that can adopted at the individual, institutional and societal levels to address these problems, bringing about a shift in culture and gender equity across career stages and scientific disciplines.
New paper from our lab: “Functional contributions of the arcuate fasciculus to language processing”
June 25, 2021
A new paper from our lab entitled “Functional contributions of the arcuate fasciculus to language processing” has been published in Frontiers for Human Neuroscience. In this study using novel tractography techniques we uncovered a broad role that the arcuate fasciculus, a large white matter bundle that connects the frontal and temporal lobes, plays in language processing, especially in comprehension and naming. The posterior segment of this tract, that directly connects inferior parietal and temporal regions, was found to be particularly crucial for supporting residual language abilities. A deeper understanding of the functionality of structural connections in the brain will help us develop more accurate models of how language is processed in the brain.

Learning in Retirement – Imaging the Fibers of the Brain: What They Tell Us About Brain Function
Dr. Maria Ivanova speaks at UC Berkeley Cognitive Neuroscience Colloquium
January 25, 2021
The talk focused on one of the most comprehensive theories about cognition and its neural mechanisms, which was proposed by a Russian physician and psychologist, Alexander Romanovich Luria. The talk presented the main tenants of Luria’s theory of systemic dynamic localization of higher cortical functions, which was based on his analysis of over 800 patient cases during World War II. The main principles of neuropsychological analysis within this framework were outlined.

Our paper on methodological aspects of lesion-symptom mapping has just been published in Human Brain Mapping. Lesion symptom mapping tools are widely used in neuroscience on brain injury data to identify the neural structures critical for a given behavior. In this published study, we provide a much-needed systematic comparison of several univariate and multivariate methods, using both synthetic and real data to identify the potential strengths and weaknesses of both approaches.
The current results showed no clear superiority of either univariate or multivariate methods overall, as accuracy of methods varied differentially depending on specific conditions. Thus, different lesion symptom mapping methods are indicated, depending on the particular study design, specific hypotheses, and sample size.
Overall, we recommend the use of both univariate and multivariate methods in tandem to enhance confidence in the results: Brain foci identified as significant across both types of methods are unlikely to be spurious and can be confidently reported as robust results.

Abstract: Advancing our understanding of lesion symptom mapping tools: An empirical comparison of univariate versus multivariate methods
Lesion-symptom mapping tools are widely used to identify the neural structures critical for a given behavior. Some studies have claimed that novel multivariate lesion-symptom mapping methods, that consider the effects of all lesioned voxels on behavior in one model simultaneously, should be superior to traditional univariate approaches, that compare performance serially on a voxel by voxel basis. However, many of these arguments have been presented theoretically without rigorously comparing the two approaches. In my talk I will discuss our current work that aimed to address these knowledge gaps and provide a comprehensive empirical appraisal of several univariate and multivariate methods with a large stroke lesion dataset, using both synthetic and real behavioral data, across a range of relevant parameters. Our results showed no clear superiority of either univariate or multivariate methods overall, as accuracy of methods varied differentially depending on specific conditions. I will conclude by outlining limitations and advantages of different approaches and highlighting methodological implications of our findings for enhancing accuracy and robustness of future lesion-symptom mapping work.

Taking on Teletherapy: Experiences and Recommendations from a PCSAS Training Clinic Adapting to COVID-19, with contributions from Dr. Nina Dronkers
April 30, 2020
Read an excerpt below:
“With over 2 million confirmed cases worldwide and most of the U.S. population currently under a “stay at home” order, the COVID-19 pandemic has caused major disruptions in health care services, including mental health care. Psychological distress is widespread partly due to increased social isolation and decreased access to care. Mental health providers must act quickly to adapt policies and delivery mechanisms to continue treatment remotely. Teletherapy — the delivery of psychotherapy via live audio/video communication software — enables clinical psychologists to deliver critical care, while maintaining public health and safety.”
