NEUROSCIENCE 103

to make a detailed structural analysis of a small number of single cells, the best choice is a

• Myelin stain

• golgi stain

• horseradish peroxidase

• Nissil stain

know where a pathway ends but would like to discover its point of orgin

• myelin stain

• horseradish peroxidase

• golgi stain

• nissil stain

identifying cluster of cell bodies , the major bulk of a nerve cell

• nissil stain

• myelin stain

• golgi stain

• horseradish peroxidase

staining insulating material that cover nerve fibers, to follow pathways carrying info from one part of brain to another

• horseradish peroxidase

• myelin stain

• golgi stain

• nissil stain

labeled with paticular flourphore emits light, when excited by it, but doesnt last indefintly,

so "you have to work quickly".

• electron microscopy

• Fluorescent microscopy

uses beams of electrons rather than light, resolution is much improved, allows to see features as small a single molecule of neurchemicals.

cannot be used on living cells though, because of required chemical and dehydration treatments

• fluorescent microscopy

• electron microscopy

an imaging technology in which computers are used to enhance x-rays

provides the structural imaging, doesn't provide info on activity levels

• (fMRI) functional MRI

• (CT) Computerized Tomography

• (PET) Positron emission tomography

• (MRI) magnetic resonance imaging

allowed researchers to observe brain activity for the first time

colors reflect amount of activity

requires exposure to low levels of radioactive substance

• (DTI) Diffusion tensor imaging

• (PET) positron emission tomography

• (MRI) Magnetic resonance imaging

• (fMRI) Functional MRI

Imaging technique that provides high resolution structural images

uses powerful magnets that produce spinning in hyrdrogen atoms

take advantage of fact brain tissue is made of different components

• (Pet) Positron emission tomography

• (MRI) Magnetic resonance imaging

• (fMRI) Functional MRI

• (DTI) Diffusion tensor imaging

This allows us to correlate brain activity with the presentation of a stimulus in living humans

use to identify parts of the brain that become active when doing a task like "finger tapping"

measures blood flow and oxygen(HEMGOBLIN PROTEIN) to analyze brain activity

• (CT) Computerized tomography

• (PET)Positron emission tomography

• (fMRI) Functional MRI

• (MRI) Magnetic resonance imaging
