活動名稱 [2019 Seminar]4/9 High-Resolution and Ultra-Fast Magnetic Resonance Imaging (MRI)  

Speaker:
Dr. Ifan Betina Ip
University of Oxford, United Kingdom

Topic: Functional Neurochemical Responses in Human Visual Cortex

Time: 02.00 pm - 04.00 pm
Date: 09th April, 2019
Location: Science Building #4, S4-209, NCU (中央大學科四館209室)

A seminar was held dated on 09th, April 2019 at the department of Cognitive neuroscience, which was attended together by students of Cognitive Neuroscience as well as students of Yang Ming University. The distinguished guest speaker of the seminar was Dr. Ifan Betina Ip, a post-doctoral research scientist working at the Department of Physiology, Anatomy & Genetics and Integrative Neuroimaging Centre. She welcomed the participants and presented an interesting topic “Functional Neurochemical Responses in Human Visual Cortex” to all.

Dr. Betina delivered her talks about the neurochemistry research. Because she suggested that hemodynamic response is ambiguous to the origin of metabolic activity and neurochemistry is a reflection of cellular events. In the seminar, she presented her study to measure dynamic levels of glutamate and GABA to visual stimulation in human primary cortex using ultra-high field magnetic resonance spectroscopy at 7-Tesla field strength. She shared the findings of her research that glutamate signals increase during visual stimulation, glutamate and hemodynamic signals are correlated, whereas GABA remains steady. The seminar was continued with a Question and Answering session, in which the students showed interests in her talk by asking more questions. In the post-seminar session, she shared her life story, what were the things that inclined her to the field of Neuroscience and how she inspired by her artwork by looking at different angles with different light effects and increased her curiosity in the field of visual human cortex. By attending the seminar, we hope we can acquire a view on functional neurochemical responses in human visual cortex.
