O primeiro colocado na OBN será indicado como representante nacional para a Olimpíada Internacional de Neurociências (International Brain Bee). No caso do primeiro colocado não poder representar o Brasil na competição internacional, o segundo candidato poderá ser indicado como representante e caso o segundo não possa, o Comitê Nacional poderá indicar o terceiro colocado.

O supervisor ou seu representante deverá acompanhar o representante da Olimpíada Brasileira de Neurociências na “18a Competição Internacional de Neurociências (International Brain Bee) entre os dias 07 e 11 de julho de 2018, em Berlim – Alemanha, durante o Fórum da Federação das Sociedades Européias de Neurociências (Federation of European Neuroscience Societies Bi-annual Forum). . O organizador da competição em 2018 será o fundador e coordenador geral, Dr. Norbert Myslinski.

Written Quiz

Live Q&A (Questions with Written Answers Part 2)

Human Neuroanatomy Practical

Participants will be asked to label neuroanatomical structures on real human brains, sections of human brains, brain models, and/or images of human brain tissues.

This involves a whole human brain, sagittal half brain, or brain stem (or a model of one). 25 parts of the brain will be pointed to, and students must recall the names and/or functions of the indicated parts and write them on their answer sheets. Students can prepare by studying any basic neuroanatomy or neurophysiology textbook or atlas.


This involves competitors rotating through stations consisting of 10 histological sections of the brain and nervous system. Students must be able to recall the names of indicated cells and parts of the nervous system. Students can prepare by studying any basic neurohistology text book.

Exemples of structures. All structures listed below may be included, and students should learn to identify them from free, online material. No other structures beyond what is listed here will be tested. It is not necessary to understand the functions of each structure- students will only be asked for the names (Tip: All structures will be presented as stained tissue sections. No electromicrographs will be included).
Cerebral cortex
white matter
gray matter
pyramidal neurons
molecular layer
granule cell layer
Purkinje cell

gray matter
Choroid Plexus
dentate gyrus
Pineal body
Pituitary gland
Spinal Cord

Parasympathetic ganglia
Auerbach’s Plexus

Patient Diagnosis

Students will spend 5 minutes alone with each of 10 patient actors. By observing them, asking them 3 questions, and ordering 2 laboratory or clinical tests they are to diagnose the patient’s neurological disorder, choosing from one of the following disorders:

Possible Neurological Diseases:

1) Huntington’s Disease

2) Parkinson’s Disease

3) Alzheimer’s Disease

4) Bipolar Disorder

5) Schizophrenia

6) Autism

7) Epilepsy

8) Stroke

9) Multiple Sclerosis

10) Amyotrophic Lateral Sclerosis

11) Rett Syndrome

12) Korsakoff´s Syndrome

13) Spinal Cord Injury

14) Prion Diseases – Cruzfeldt-Jakob disease

15) Down Syndrome

16) Neurological AIDS

17) Addiction

18) Tourette’s Syndrome

19) Hydrocephalus

20) Cerebral Palsy

Patients are only allowed to answer “yes”, “no” or “I don’t know” to the 3 questions. Students will select from a list of tests and will immediately be given the results to help their diagnosis.

Possible Diagnostic Tests are:

1) Intelligence test

2) Memory test

3) Blood test

4) DNA test

5) Lumbar puncture

6) Blood pressure measurement

7) Biopsy and neuropathology

8) Nerve conduction test

9) Reflex evaluation

10) Motor evaluation

11) Sensory evaluation

11) Electroencephalogram

12) Electromyogram

13) Cerebral blood flow study

14) CT scan

15) PET scan

16) functional MRI

17) MRI scan

Written Multiple Choice Exam

Competitors will be given the same 25 questions orally one at a time. They will have 15 seconds to write the answers on a pad given to them. At the end of the 15 seconds, they will each read their answers out loud. Students can prepare by studying Neuroscience: the Science of the Brain (2003)

Questions with Written Answers Part 2

Competitors will be given the same 25 questions orally one at a time. They will be in the form of short case studies. They will have 20 seconds to write the answers on a pad given to them. At the end of the 20 seconds, they will each read their answers out loud. Students can prepare by studying Neuroscience: the Science of the Brain (2003)
