研究室紹介
Professor Younghee Lee's research lab focuses on the neural circuits and molecular mechanisms underlying motivated behaviors, particularly food-seeking and consummatory behaviors, with a strong emphasis on the role of lateral hypothalamus leptin receptor (LepR) neurons in regulating feeding behavior. The lab integrates advanced neurophysiological techniques such as fibre photometry and micro-endoscopy to dissect the temporal dynamics of distinct neuronal subpopulations during appetitive and consummatory phases of eating. Additionally, the lab investigates the pathophysiological roles of gut hormones like GLP-1 in metabolic disorders such as obesity and type 2 diabetes, aiming to uncover novel therapeutic targets. The research also extends to medical education, exploring communication skills in preclinical medical students and developing assessment models for clinical training.

15Abstract For survival, it is crucial for eating behaviours to be sequenced through two distinct seeking and consummatory phases. Heterogeneous lateral hypothalamus (LH) neurons are known to regulate motivated behaviours, yet which subpopulation drives food seeking and consummatory behaviours have not been fully addressed. Here, in male mice, fibre photometry recordings demonstrated that LH leptin receptor (LepR) neurons are correlated explicitly in both voluntary seeking and consummatory behavio
technologies in the neuroscience field allows us to reevaluate the multiple components and phases of food-related behaviors. Focused on the cognitive, executive, behavioral and temporal aspects, food-related behaviors can be distinguished into appetitive phase (food craving→food seeking) and consummatory phase (food consumption). Food craving phase is an internal state or stage in which the animal has the motivation to eat the food but there is no actual food specific behaviors or actions. Food
PURPOSE: Communication is a core clinical skill that can be taught and learned. The authors intended to develop a patient-doctor communication model for teaching and assessing undergraduate medical students in Korea. METHODS: To develop a model, literature reviews and an iterative process of discussion between faculty members of a communication skills course for second year medical students were conducted. The authors extracted common communication skill competencies by comparing the Kalamazoo C
Obesity and its comorbidities, such as type 2 diabetes, are major public health diseases in modern society. Despite the currently significant unmet needs of type 2 diabetes patients, effective and safe pharmacological treatments that deliver adequate weight loss and glucose control have not been discovered. Anorectic gut hormone, glucagon-like peptide 1 (GLP-1), is widely used to treat obesity and diabetes.1,2 GLP-1 is a type of incretin released from the L cells of the large intestine and di
The purpose of this study was to explore the relationship between the personality types of premedical students and their self-assessed communication skills and attitudes toward a communication skills course.
Genetic variation in cis-regulatory elements related to splicing machinery and splicing regulatory elements (SREs) results in exon skipping and undesired protein products. We developed a splicing decision model to identify actionable loci among common SNPs for gene regulation. The splicing decision model identified SNPs affecting exon skipping by analyzing sequence-driven alternative splicing (AS) models and by scanning the genome for the regions with putative SRE motifs. We used non-Hispanic Ca
PURPOSE: The goal of this study was to explore what kind of additional information is provided by the descriptive comments other than the rating scales, on the physician-patient interaction (PPI) in the clinical performance examination (CPX) and its feedback role in identifying students' strengths and weaknesses in communication skills. METHODS: The data were collected from 18 medical schools in Seoul and Gyeonggi region, which participated in the CPX for fourth-year medical students in 2006 and
Biodegradable superabsorbents, hydrolyzed AN(acrylonitrile)-grafted-SA(sodium alginate) copolymers were prepared in this study by graft copolymerization of acrylonitrile on sodium alginate and the subsequent hydrolysis of the resulting grafted copolymer. The absorbency was found to significantly depend on the % add-on, graft copolymerization conditions and hydrolysis conditions. The optimum condition for graft copolymerization to obtain the maximum % add-on (64.5%) was 4g SA, 12g AN, and 8.42g H
Physiological needs evoke motivational drives that produce natural behaviors for survival. In previous studies, the temporally intertwined dynamics of need and motivation have made it challenging to differentiate these two components. On the basis of classic homeostatic theories, we established a normative framework to derive computational models for need-encoding and motivation-encoding neurons. By combining the model-based predictions and naturalistic experimental paradigms, we demonstrated th

Purpose: This study was designed to examine fear of falling, depression, physical fitness, and physical activity and further to identify the factors that predict physical activity among community dwelling elders. Methods: This study was a cross-sectional descriptive survey. Participants were 153 community dwelling elders from G city. Data were collected using structured questionnaires and were analyzed using descriptive statistics, x 2 -test, t-test, ANOVA, and multinominal logistic regression a
Objectives For the successful introduction and settlement of the high school credit system, it is important to expand the role of teachers related to the operation of the high school credit system and secure expertise. To this end, it is necessary to examine the actual difficulties experienced by high school teachers in the process of operating the high school credit system and derive the new role performance required by teachers based on this. Methods Therefore, in this study, the difficulties
