| 2883702480 | grey matter | neurons | 0 | |
| 2883704164 | white matter | axons | 1 | |
| 2883803723 | interneurons | important for mini-column circuit | 2 | |
| 2883806056 | pyramidal cell | pyramid shape | 3 | |
| 2883806057 | soma | cell body | 4 | |
| 2883808698 | axon | - efferin; outgoing signal - reaches to next outpost | 5 | |
| 2883810401 | dendrites | incoming signal; afferin | 6 | |
| 2883813462 | granular laminar (IV) | comes from the thalamus | 7 | |
| 2883819553 | neuron | - work force; sends signals; left to right - cell of the central nervous system (CNS) | 8 | |
| 2883821741 | glial cells | support neurons to work and provide nutrients | 9 | |
| 2883824097 | dendrites | info flows in and out | 10 | |
| 2883824098 | axon terminal | reach for next terminal but never touch | 11 | |
| 2883831990 | cell body | - makes energy - nucleus - inside soma | 12 | |
| 2883834068 | axon hillock | - wall that energy has to cross to get information to travel down the axon - counts input per second - "dam wall" | 13 | |
| 2883836333 | contrasts | synchronized behaviors for different things; silent when nothing happens to explosive excitation | 14 | |
| 2883840405 | resting potential | - neuron is quiet and waiting - ions are not evenly distributed | 15 | |
| 2883845886 | excited phase | - dendrites get excited (ionic charge) - one excitation at one dendrite doesn't mean neuron will get excited | 16 | |
| 2883851008 | temporal summation | either one neuron firing multiple times | 17 | |
| 2883853225 | spatial summation | neurons agree to send message all at once | 18 | |
| 2883860130 | decrementing signal | axon hillock excited so ions inside/outside flow | 19 | |
| 2883862852 | action potential | shoots down axon and doesn't stop; same strength regenerated to trigger next neuron | 20 | |
| 2883865837 | myelin sheath | - insulation around the wire - causes action potential to accelerate | 21 | |
| 2883871779 | unmyelated axons | local and slower | 22 | |
| 2883873212 | myelenated axons | takes up more energy and faster | 23 | |
| 2883875682 | depolarization | haven't fire the cell wall but changed the charge (closer to the axon hillock threshold) | 24 | |
| 2883878000 | hyperpolarization | what inhibitory neurons do; keeps it more negative and more difficult to fire | 25 |
