what are the effects of the thyroid in the brain official ppt
TRANSCRIPT
INTRODUCTION
The Thyroid˃A gland is located at the
base of the neck. ˃Secretes T3 and T4˃Types of thyroid disease:
˃ Hypothyroidism˃ Hyperthyroidism
Trachea
Right Thyroid Gland
Left Thyroid Gland
CURRENT KNOWLEDGE
˃People tend to relate the thyroid only with metabolism˃20 million Americans suffer from some kind of thyroid
disease˃60% are unaware of their condition˃Every cell in our body contains a receptor for the
hormone˃Affects:
˃ Cardiovascular system ˃ Metabolism˃ Regulation of temperature
PURPOSE
˃ Inform people about what they are missing
˃After the experiment find a way to:
˃ Treat existing thyroid disease˃ Prevent the disease from
getting worse˃ Detect the symptoms faster
THE BRAIN AND THE THYROID
˃The amount of hormone secreted is controlled by the pituitary gland in the brain.
˃Part of the brain responsible for learning and memory:
˃ Declarative memory˃ Hippocampus˃ Parahippocampus˃ Areas of the cerebral cortex
HYPOTHESIS
• When having a low production of the thyroid hormone the hippocampus will shrink, making it harder for the individual to retain new memories or remember old ones. When there is a high production of the thyroid hormone the brain will speed up and eventually wear out the hippocampus itself.
METHOD
˃Step 1: Find volunteers
˃Step 2: Get the required papers to carry out the experiment
˃Step 3: Divide into groups
˃Step 4: Submit the subjects to a series of tests
˃Step 5: observe, write down the results, and repeat

TESTS
Written Test˃Answer a series of
questions to determine:˃ Lifestyle˃ State of the condition ˃ Eating habits
˃Problem solving to determine memory and learning skills
TESTS
Practical Exams˃Physical tasks such as:
˃ Multitasking˃ Solving non- written
problems˃ Motor responses ˃ Tests would be performed
once or twice a week for about a year.
MRIS AND FMRIS
˃ These scans use magnetic fields to map an image of the body.
˃ Can measure brain activity by the flow of oxygen- rich and oxygen- poor blood
˃ These types of blood respond differently to the magnetic field
˃ Start by taking a baseline picture (no brain activity)˃ Then compare it with a brain completing certain tasks.
DATA ANALYSIS
˃ Evaluate the written and practical exams with points and percentages.
˃ Medical tests will be evaluated by a professional.
˃ Determine the state of the individual’s declarative memory
DISCUSSION
˃After the tests have been evaluated I will determine if, in fact, having a problem with your thyroid gland has a direct effect on an individuals learning skills and capacity to retain memory.
PROBLEMS
˃No experiment is 100% perfect or certain and this is not the exception.
˃ I may run into some problems such as:˃ 1. The thyroid diseases affect each person differently.˃ 2. I cannot control what the subject does after he/she leaves
the experimental facility. ˃ 3. Human error
CONCLUSION
˃ The purpose of the experiment is to inform and help the growing number people who have some type of thyroid disease.
˃With modern technology we can investigate how the human mind works.
˃The tiny thyroid gland in our neck is more important than we think.
˃This experiment only continues the endless search for the mysteries that are hidden in our brain.
