ch 5 Imaging & ch 9

Functional

100

I use ultrasound, a high frequency sound waves, I measure blood flow detects changes in blood volume in specific brain regions, used on infants, measures brain  activity by detecting changes in blood flow using ultrasound waves, when brain regions becomes active, blood vessels increase there and alter passage of ultrasound through that brain region 

I am Functional ultrasound imaging (FUS)

200

I stimulate the brain areas to temporarily increase activity and assess cognitive and behavioral effects. I am the opposite of TMS

I am transcranial electrical stimulation (TES)

300

Can be used to create permanent lesions, used to treat tremor, activates brain structures to study role in functions. What am I? 

Transcranial ultrasound stimulation (TUS) 

400

I am placed on the scalp that records electrical signals from the brain activity (action potentials , postsynaptic potentials) measures: reflects brains alertness or relaxation. What am I?

Scalp electroencephalography (EEG) 

500

records from the scalp, detects magnetic signals generated by nuerons when they fire, localizes brain activity with high spatial resolution in cortical or subcortical areas, measures magnetic field generated by activity providing better spatial resolution, measures in changes in magnetic fields produced by neural activity at the scalp. What am I?

MEG, Magnetoencephalography 

Strutural

100

I am both strutural and functional imaging. I have BOLD singals which is blood oxygen level dependent signals parts of the brain active or inactive during cognitive and behavioral tests. I CAPTURE INCREASE OF OXYGENATED BLOOD FLOW TO ACTIVE AREAS OF THE BRAIN. Poor at spatial resolution of timing of neural events occur. What am I? 

Functional MRI

200

I do not use radiation, I use magnetic field and radiofrequency pulses, the hydrogen atoms are caused by radiofrequency pulses that cause them to align to the magentic field, you are able to get a clear and detailed image because the water that varies in the brain and hydrogen atoms. What am I? 

Magnetic resonance imaging (MRI) 

300

I use x-rays that are for 5 minutes, I visualize stroke and tumors, computerized axial tomography, visualize the brain and other internal structures. What am I?

I am  a CT scan

400

There are 2 compenents. One you are able to see the overall shape of the neuron by using a silver chrome that stains the neurons black. What am I?

You are able to count how many nuerons in certain area, by counting purple dots. What am I? 

Golgi Staining

Nissel Staining 

500

You are able to detect myelination, the myelination fibers, nuerpil, and nerve cells by using different colors. What am I? 

Myelination Staining 

functional/ midbrain,forebrain, hindbrain

100

Injecting radioactive fluid to detect tracer of injury or disease, reliant on glucose metabolism shows high consumption of energy, metablism process helps us see on colored map the brain activity, helps us see which areas are more engaged during specific tasks and activities. What am I? 

Positron emission tomography (PET)

200

Technique of foil next to skull, temporarily turns off areas of the brain to assess function on disruption on cognitive and behavioral effects, magnetic stimulation, establish casual relationships between brain activity and cognitive functions. Opposite of TUS. What am I? 

Transcranial magnetic stimulation (TMS)

300

Prosencephalon is another word for? 

Forebrain 

400

mesencephalon is another word for 

midbrain 

500

Rhombencephalon is another word?

Hindbrain 

Development of NS

100

I am a fertilized egg, new cells are created through cell division, can develop into any type of cell in the body. What am I?

totipotent

200

Classes of body cells, the developing cells have the ability to develop into many, but not all. What am I?

Pluripotent

300

embryo is continuing to develop, new cells becomes specialized and develop in different kinds of blood cells

most developing cells become unipotent, they can develop into only 1 type of celll (bipolar cells)

What am I?

Multipotent

400

embryonic stem cells are? 

totipotent, multipotent, and pluripotent 

Stages of neural development

100

where production of neurons take place,What am I?

Neurogenesis

200

I am a movement of cells to establish distinct nerve cell populations. What am I?

Neural migration

300

Transformation of precursor cells into distinctive types of neurons/glia. What am I?

Differention

400

I am an establishment of synaptic connections as axons/dendrites grow. What am I?

Selective death of nerve cells. What am I? 

Synaptogenesis

apoptosis 

500

Axons are myelinated by glia cells. what am I? 

refining of synaptic connections, what am I? 

Myelination

Synaptic pruning
