Unit 1 - 2 Flashcards
Somatic intervention
Manipulating the body may affect behavior
Behavioral intervention
Experience affects the body (including the brain)
Correlation
Body and behavioral measures Covary
Idea of conserved function
Arose from a common ancestor; includes structure and function of neurons
Invasive Histology Techniques
Studies the brain at the cellular level and must be performed on tissue samples 
Non-invasive Histology Techniques
Studies, broader functioning in a living brain, generally by images 
Nissl staining (invasive)
Fills all cell bodies, because it binds to mRNA, label all cells in a region
Golgi staining (invasive)
Fills cells completely revealing details, including projections. Real fine details of individual neurons (one at a time)
Autoradiography (invasive)
Detection of radioactive compounds in the brain
Immunohistochemistry (IHC) (invasive)
Detection of antibodies raised against a particular protein (studies immune cells)
In situ hybridization(invasive)
Probes to detect RNA or DNA only of genes that are expressed in that neuron 
CAT (non-invasive)
Computerized Axial Tomography
Detects major disruptions, such as strokes or tumors

MRI (noninvasive)
Magnetic Resonance Imaging
 Enables us to see fine structure and recognize subtle changes in the brain by using protons and radio waves 
fMRI (noninvasive)
Functional MRI
Detect small changes in brain metabolism and detects activity in real time
PET (noninvasive)
Positron Emission Tomography
Detects radioactive chemicals in the brain to observe brain activity
