2019 Championship


The 2019 Brain Bee World Championship was held in conjunction with the 10th IBRO World Congress of Neuroscience September 19-23, 2019 in Daegu, Korea. Information about the IBRO World Congress of Neuroscience can be found on the IBRO website.

The competition was hosted by the Korea Brain Research Institute, Kyungpook National University, and the IBRO Congress. Twenty-eight national and regional champions traveled from all six continents to demonstrate graduate-level knowledge in Neurosciences, Neuroanatomy, Neurohistology, and Neurological Patient Diagnosis.

The World Champion was Yidou Weng, representing China. Yidou was awared with $3,000, a $4,000 scholarship to attend the 2020 Georgetown Neuroscience Summit, and a travel stipend to assist with her trip to Washington, DC. Second place went to Natalia Koc from Poland, earning her $2,000, and third place was awarded to Kamand Soufiabadi from Iran, earning her $1,000.

International Competition Overview

The Brain Bee World Championship is designed to be a high-level and friendly academic competition. The material draws from university and medical school course content and requires thoughtful preparation. All participants are expected to support one another throughout the experience, during and between contest sections.

The IBB organizers reserve the right to amend the details of the competition at any stage.

Competition Sections

Upon arrival to the competition, student participants will receive extended and updated rules for each competition section. At the start of each section, the neuroscientist judges will provide an overview of the rules. Official timekeepers will oversee that all questions are complete within the allotted times.

For example, during the Neuroanatomy Section, students will rotate every 90 seconds between table stations, each with one brain and one affiliated question. During the Live Question and Answer Section, different questions may be allotted different lengths of time, which will be clearly stated during the event.

Responses will be graded as correct or incorrect: no partial credit will be granted. Incomplete answers are counted as zero points.


Video footage of patients will be shown alongside a written medical history. Students may request results from two lab or imaging exams to aid in the diagnosis. This section will be worth 20% of the final score.

The Patient Diagnosis Section consists of 10 videos of patients, each with one of the possible neurological disorders listed below. The video will portray motor and/or other visual symptoms of the patient (without sound), and a brief written history, as told by the patient, will be provided. Each disorder will be presented in a common form (no rare forms of the disorders).

After watching each video and reading the patient history, students should request the results of two of the available clinical, laboratory, or imaging tests, listed below. The appropriate results for the tests will be provided immediately, for example, "Normal", "Abnormal", "Enlarged Lateral Ventricles", "Tumor detected in the Occipital Lobe", "Defective Huntingtin gene", or other result, depending on the neurological disorder and the requested test. The task then is to diagnose the most likely disorder, with the list of possible disorders and tests provided. Students are given 5 minutes total per diagnosis.

Rules and Assistive Tools Overview

The International Brain Bee expects a high standard of integrity from each student participant. Absolutely zero tolerance will be demonstrated toward acts of cheating, which will result in immediate elimination from the contest. The event will be conducted professionally and in a way that fosters a positive and fair experience for everyone. Student contestants will be given more thorough rules as the competition date approaches.

Contestants may bring their personal writing instruments, such as pens, pencils, erasers, and pencil sharpeners, into the examination rooms. For students from non-English speaking backgrounds, a translation dictionary without any notes may also be used. All translation dictionaries will be checked before exam sections.

Not permitted are mobile phones, programmable calculators, other electronic devices, or any other written materials. Posession of such items in restricted areas may result in immediate disqualification.
