PSY290H5 Chapter Notes -Brainstem
Document Summary
When a trait is conserved, it means that the trait is passed on to a common ancestor and two or more descendants. Parts of a rat s brain were damaged to see the effects of the rat s maternal behaviour. They provide structure to the brain , give nutritional support to the brain. And provide raw materials and chemical signals that alter the neuronal sturucture snd excitablility. Describe the different types of glial cells and what their function is. Star-shaped astrocytes detects neural activity and regulate adjacent capillaries to control blood flow which supplies neurons with more energy when they are active. Microglial cells break down any debris that forms especially after damage to the brain. Unmyelinated axons are in the troughs of glial cells. Away because it receives information and then sends it on. Transmits the cell s electrical impulses from the cell body. Describe the differences between all the different neurons.
