Host CNLM Panel ‘How Addiction Hijacks the Brain’

1 minute read

Published:

This evening, I hosted the CNLM ambassador’s panel “How Addiction Hijacks the Brain: What Animal Models Can Tell Us About the Neurobiology of Drugs of Abuse”. This panel features four UCI addiction experts Dr. Christie Fowler, Dr. Ariana Nelson, Dr. Jessica Childs, and PhD candidate Mitchell Farrell. This is the second panel hosted by CNLM Adult Outreach Committee and we have over 60 attendees from the Irvine community. Although the audience size in summer is smaller than during the school year, I really enjoyed facilitating the panel discussion, learned about neural mechanisms underlying drug addiction, and was deeply inspired by scientists who are determined to devote their lifelong career to improving people’s mental health.

Today, I gave a short talk about my recent research on head direction signals in human navigation at the UCI Associated Graduate Students (AGS) Virtual Symposium. The questions I received gave me some clues on the knowledge gap between scientists who use fMRI and other biologists about my particular research. And I’d thus better polish my future talks to fill the gap. In addition, I’m glad to receive the Audience Choice Award, which is an acknowledgment for my research and presentation.

I’m glad that our team, PawPaw Therapeutics, is the 1st place winner of the Business Pitch Competition 2021 organized by UCI Beall Applied Innovation and GPS-STEM! Our team is made up of me and other six biology PhD students and postdoc. We started with a medical research discovery, developed it into a business idea as a new type of cancer therapy, and pitched a business canvas to judges. This time, I gained industry insights as a STEM scientist and learned how research discoveries are turned into real-world applications. It’s my honor to work with such a pawsome team.

Present at INP Recruitment Session

less than 1 minute read

Published:

This morning, I presented my recent research on head direction signals in the human brain to prospective interdepartmental neuroscience program (INP) PhD students. It was a 5min short presentation with 3min Q&A. I received many interesting and diverse questions from prospective students and also learned about my colleagues’ cool research through their presentations. I hope many young and energetic ‘brains’ will join the UCI neuroscience community in the coming year!

Today, I presented my latest research on head direction signals in the human brain at the Sfn Global Connectome. At the conference, I discussed with neuroscientists who study head direction signals in rodents, macaques, and drosophila. The clues I gained from the fascinating discoveries in other species really helped me consolidate my theories on how travel direction system works in the human brain.

I was fortunate to attend this year’s virtual Conference on Neural Information Processing System (NeurIPS 2020) thanks to the registration support from the NeurIPS 3rd Robot Learning Workshop. Although this is not a conference I’m regularly involved in, attending this conference is quite an experience filled with serendipity.

Over the past weekend, I participated in a Datathon “WaiDATATHON For Sustainable Future” hosted by WaiACCELERATE & Women in AI (WAI). As a member of the Foodwizer team, I worked on the challenge “Recommending dishes based on personal nutrient needs”. This time, I implemented association rule mining on a recipe ingredients dataset. Through this analysis, I discovered the probability of the co-occurrence of ingredients in a recipe. And our global team (with Betty from Netherland and Kirthy from India) won the 2nd place of the Datathon!

Today, I presented my talk “Travel Direction as a Fundamental Component of Human Navigation” at the data blitz session of the 2020 Interdisciplinary Navigation Symposium (iNAV). The study is to look at the role of travel direction in the internal representation system of human navigation using a traditional paradigm in vision neuroscience - motion adaptation. The data will be incorporated as part of the first chapter of my Ph.D. dissertation and a recording of the talk should be available on the iNAV website since next week.

The processing course of conflicts in third‐party punishment: An event‐related potential study

Published in PsyCh Journal, 2014

In third-party punishment, people encountered more conflict when they did not change unfair offers. Furthermore, it was implied that altruistic punishment, rather than rational utilitarianism, might be the prepotent tendency for humans that is involved in the early stage of decision-making.

The effect of altruistic tendency on fairness in third-party punishment

Published in Frontiers in Psychology, 2015

In third-party punishment, the altruistic tendency effect influences fairness consideration in the early stage of evaluation. Moreover, the results provide further neuroscience evidence for inequity aversion.

Telling right from right: the influence of handedness in the mental rotation of hands

Published in Cognitive Research: Principles and Implications, 2020

Our findings demonstrate that embodied experience influences spatial thinking about right hands, which might account for the presence of world knowledge variability in MRT, while also suggesting that common external experience shapes performance in spatial thinking tasks. These findings demonstrate that investigations in spatial thinking tasks might overlook the nuances reflecting world knowledge versus embodied experience if researchers do not recruit left-handers.

Neural Representation of Direction in Exploration and Navigation

We show different direction classification performance in neural networks during navigation in a complex environment. We also observed a relationship between individual differences in the classification strength in each brain region and navigation performance.

Handedness in the Mental Rotation of Hands

We show that embodied experience influences spatial thinking about right hands, which might account for the presence of world knowledge variability in the mental rotation task, while also suggesting that common external experience shapes performance in spatial thinking tasks.
