the cerebral cortex contains up to 6 of these layers of cell bodies
What are laminae?
100
a method of examining brain anatomy that applies a powerful magnetic field
What is an MRI?
100
the production of new cells
What is proliferation?
100
the experiment on a salamander that when a new leg was attached it moved in synchrony with the existing leg. It was discovered that the axons found their way to the correct muscle.
What is Weiss' experiment?
100
if an axon does not make contact with an appropriate postsynaptic cell by a certain age, it kills itself through this process.
What is apoptosis?
200
this lobe controls information about touch sensation and body location
What is the parietal lobe?
200
records electrical activity in the brain through electrodes
What is an electroencephalograph (EEG)?
200
after cells have differentiated as neurons or glia they do this. The second process in the development of neurons.
What is migrate?
200
the experiment on cutting the optic nerve of a frog and how the nerve grew back and attached to the correct spot on the tectum
What is Sperry's first experiment?
200
a chemical that promotes the survival and activity of neurons. NGF is an example
What is a neurotrophin?
300
this occurs if you perceive two sensations as happening at the same time in the same place
What is the binding problem?
300
measures the faint magnetic fields generated by brain activity
What is an MEG?
300
the third process in the development of neurons, when the neuron forms its axons and dendrites.
What is differentiate?
300
cutting the optic nerve and then rotating the eye 180 degrese. Nerves grew back to their original target even though it was in a different place altogether.
What is Sperry's second experiment?
300
this guides neuronal changes, develops a thicker cortex, more dendritic branching, and improved learning.
What is experience?
400
the process of relating skull anatomy to behaviour
What is phrenology?
400
provides a high-resolution image of activity by recording the emission of radioactivity from injected chemicals
What is a PET?
400
a later slower stage of neuronal development, the process by which glia produce the insulating fatty sheaths that accelerate transmission. This stage continues gradually for decades.
What is myelination?
400
a protein that is 30 times more concentrated in the dorsal retina and 10 times more concentrated in the ventral tectum. It attracts axons with a high concentration of the same protein, which explains how some axons regrow to the correct spot.
What is TOPdv?
500
a method of examining brain anatomy where dye is injected into the blood and then the person is placed in a scanner while xrays are passed through the head
What is a CAT scan?
500
this scanner detects changes in the oxygen content of the blood
What is fMRI?
500
the final stage in neuronal development, the formation of synapses.
What is synaptogenesis?
500
a protein delivered by a muscle that promotes the survival and growth of the axon.
