Human Brain (00:59)
Have you ever wondered how we perform our many activities? The human brain makes it all possible. On this episode, we will learn how the brain works, then consider possible cures for Alzheimer's and strokes.
Brain Parts (02:06)
Learn about the different parts of the brain and their functions.
Comparison of Human and Animal Brains (01:21)
The human brain has characteristics not seen in other animals. We look at models of human and other mammal brains.
Damaged Brain (01:29)
MRIs and studies of brain damage effects have improved our understanding of the brain. We see some damaged brains.
Growing Live Brain Tissue (01:38)
To find the most effective brain disease treatment, scientists need to conduct research on living brain tissue. A team has grown living brain cells in the lab.
Microglial Cells (01:58)
A research team studies microglial cells, which show promise in clearing up plaques associated with Alzheimer's. These cells also damage brain cells, so researchers need ways target them at toxins.
Researching Alzheimer's Drug (03:23)
Soluble amyloid precursor protein a (sAPPa) is related to proteins that cause plaques, but sAAPa may protect the brain from Alzheimer's. It has been effective in rats, but drug makers must miniaturize it so it crosses the blood stream into the brain.
Stroke Research (01:36)
Stroke victims today need clot-busting drugs, but often do not reach hospitals in time. A team is working on electromagnetism to promote brain plasticity, to supplement physiotherapy.
Magnetic Stroke Therapy (01:35)
Meet a patient participating in a stroke treatment study. The therapy creates a magnetic field intended to help neurons fire.
Brain of Stroke Patient (02:05)
Using an MRI representation, a researcher explains how the patient's stroke damages pathways, how this affects brain activity, and how experimental treatment is improving results.
Drug Research for Stroke (02:17)
The peri-infarct cortex surrounding stroke-damaged tissue sleeps as glial cells respond to the stroke by blocking compensatory signals. A drug designed to allow these signals through crystallizes in the kidney; a major problem.
Summary: What is Science Doing to Treat Alzheimer's and Stork? (00:33)
The brain is remarkable but fragile. Scientists are working to find treatments.
