Doctoral Dissertation Findings
Chen, C.-M., Lakatos, P., Shah, A.S., Mehta, A.D., Givre, S.J., Javitt, D.C., & Schroeder, C.E. (2007). Functional anatomy and interaction of fast and slow visual pathways in macaque monkeys. Cerebral Cortex, 17: 1561-1569. PMID: 16950866
Summary: Current dynamic models of visual processing suggest that rapid inputs to higher order ventral stream regions modulate the processing of slower, more information-dense inputs. There is also an indication that the rapid “framing” inputs may not utilize standard feedforward pathways. To evaluate these propositions, we measured the timing, areal distribution, and laminar profile of fast, wavelength-insensitive and slower, wavelength-sensitive responses in V1 and extrastriate areas, using laminar current-source density analysis in awake macaque monkeys. There were two new main findings: 1) Wavelength-sensitive inputs in areas V1, V4, and IT cortex lagged the wavelength-insensitive responses by significant margins; additionally, this lag increased over successive levels of the system. 2) Laminar activation profiles in V4 and IT were inconsistent with feedforward input through the ascending ventral cortical pathway; the likely alternative input routes include both lateral inputs from the dorsal stream and direct inputs from nonspecific thalamic neurons.
Importance: Based on these results, a review in Nature Reviews Neuroscience (Pessoa & Adolphs, 2010) expressed that “we argue that visual pathways other than a colliculus–pulvinar–amygdala pathway carry out this role (see also REFs 68,69).” Another review titled “Visual Consciousness Revisited” (Tapia & Breitmeyer, 2011) stated: “According to a general “frame-and-fill” approach (Chen et al., 2007) to visual processing, the M channels responding to their preferred low-spatial-frequency content…this fast activation potentiates, or “frames,” the processing of the later arriving inputs along the slower ventral P pathway that carries the “fill” consisting of the detailed form and color- and luminance-contrast contents required to construct a high-resolution object representation (Chen et al., 2007).”
Postdoctoral Research Findings
Summary: During my post-doctoral trainings, I continued to pursue my goal of understanding interactive mechanisms among visual cortical areas in macaque monkeys. Our initial findings (Rajkai, et al., 2008) laid a foundation for describing saccade mechanisms across the visual system (Chen et al., in preparation). One of my post-doctoral research objectives was to learn how to translate physiological knowledge into early detection and treatments for neurophysiological disorders. In one project (expanded from my master’s thesis), we used scalp visual-evoked potentials to detect visual pathway malfunction to determine possible early glaucoma development (Zemon, et al., 2008). In another project, we were interested in testing the hypothesis that auditory hallucinations stem from the failure to generate an efference copy, which prepares the auditory cortex to distinguish self-generated speech or thought from externally generated language. We were able to test this hypothesis by analyzing electrocorticogram data from presurgical epilepsy patients. The results of this investigation provided evidence of a manifestation of an efference copy (Chen, et al., 2011). To further integrate a variety of measures and analyses, I led a project, supported by the Lieber Center for Schizophrenia Research and Treatment, to investigate a model positing causal relationships among prefrontal GABAergic abnormalities (measured via magnetic resonance spectroscopy), disordered neural synchrony (measured via topographical EEG), and impaired working memory (assessed via neurocognitive tasks).
Importance: My post-doctoral research focused on advancing the state of science in brain and behavior research through interdisciplinary research, ranging from basic to clinical topics. The field has supported the integration and translation of basic and clinical neuroscience research, and our research studies demonstrate the growing need for more basic and translational research that extends across traditional disciplinary boundaries.
Chinese-Speaking Schizophrenia Patients
Yang, L.H., Chen, S., Chen, C.-M., Khan, F., Forchelli, G., & Javitt, D.C. (2012). Schizophrenia, culture and neuropsychology: sensory deficits, language impairments, and social functioning in Chinese-speaking schizophrenia patients. Psychological Medicine, 42(7): 1485-1494. PubMed PMID: 22099474
Summary: This is the first study to evaluate auditory processing in tonal-language schizophrenia patients. Consistent with the priori prediction, schizophrenia patients were impaired in both basic tone processing and auditory word processing, with significant correlation between the two measures. Schizophrenia patients with auditory sensory impairments showed significantly worse social-occupational function than those with intact word recognition, suggesting a link between sensory impairment and overall functional outcome. Thus, while neurophysiological deficits associated with schizophrenia patients are likely the same across cultures, consequences of such deficits may be language and culture dependent.
Importance: This study pulls together different measures to ask cross-cultured questions about the sensory deficits and language processing impairments in schizophrenia. This is the first study to evaluate auditory processing in tonal-language schizophrenia patients. Based on the present findings, we hope to develop international collaborations on cross-cultured studies in schizophrenia. Most important of all, sensory and language processing impairments in schizophrenia are significant causes of social dysfunctions, thus understanding their etiology and identifying potential treatment targets could have a major impact on public health.
