There isnt just one area for a specific task
PET scan
Positron emission tomography
Indirectly measures O2 use
fMRI
Functional magnetic resonance imaging

Basal ganglia
Hippocampus
Amygdaloid nuclei
Overlying lobes
Midbrain
Tectum w/ superior and inferior colliculi
Cerebral peduncle
Motor Cortex
Precentral Gyrus
Somatic Sensory Cortex
Postcentral Gyrus
Wernicke’s area
Language processing
Broca’s area
Produces speach
Aphasia
Language disorder that affects a persons ability to communicate
Unipolar Nerve Cell
Cell body at one end
Axon and dentrites on the other
Bipolar Nerve Cell
Dendrites then cell body then axon
Pseudounipolar Nerve Cell
Dendrites then uninterrupted axon with cell body sprout
Oligodendrocyte
Support cell of the CNS myelinates multiple nerve cells
Schwann Cell
Support cell of the PNS myelites by wrapping nerve
Protoplasmic Astrocyte
Found in gray matter
Sheet like appendages
Fibrous Astrocyte
Found in white matter
Long, fine processes that contain intermediate filaments
Microglia
Immune system cells of the NS
Macroglia
Oligodendrocytes
Schwann Cells
Astrocytes
Regions of a nerve cell
Input Region
Integrative Region
Conductive Region
Output Region
Feed Forward Inhibition
Enhances effect of pathway by suppressing opposite affect
Feedback Inhibition
Self Regulation effect that turns off effect at the same time as causing it
Plasticity
Short term physiological changes can change the effectiveness of a synapse
