Notes: Topic 2 (chpt.7) Flashcards
What part of the brain is involved with language functions?
The brokers area (left frontal lobe)
What is neuropsychology
The study of the relationships between brain function and behaviour with a particular emphasis on humans
Why is “Behavioural Neuroscience” different than Neuropsychology?
It includes both humans and non-humans, but still very similar
What is Ethology?
The study of non-human animal behaviour, especially in nature (not so much in labs
Why were stains developed?
to allow visualization if individual cells and structures under the microscope
What are the 3 types of stains?
Golgi stains
Myelin stains
Nissl stain
What is a Golgi stain?
A stain that randomly stains about 5% of neurons on a slide, which is better because it would be hard to see everything if everything was stained
What is a Myelin stain?
A stain that binds on to the myelin sheath that surrounds axons of neurons (insulating area/white matter)) meaning it stains more of the inside
What is the Nissl stain?
Stains the cell bodies (grey mater) of neurons (stains more of the outside)
What is an Optical (light) microscope?
A microscope that relies on light bouncing off the sample to see it, it also magnifies the image
What are Scanning Electron Microscopes? (SEM)
Electrons bounce off the sample and are collected to produce 3D images of the SURFACE
What are Transmission Electron Microscopes (TEM)
same as SEM microscopes but looks at the INSIDE of a cell and typically uses thin slices
What is Autoradiography?
Stains and reveals which neurons are “active”
What is “immunocytochemistry”?
a technique that uses ANTIBODIES attached to a dye to identify cell components
What is “Multi-photon Excitation Microscopy?”
A fluorescence imaging technique (not a stain) that uses chemicals. Can work on living tissue
