| Very slow | Synaptic delays, synaptic fatigue and the slower transmission speed of dendrites should prevent brain signals in the cortex from traveling at much more than a snail's pace of about a centimeter per second. |
| Very volatile and unstable | Synapses and dendritic spines are made of proteins with lifetimes of only a few weeks or less, and individual synapses and individual dendritic spines don't last for years, unlike memories lasting decades. |
| Very noisy | There are many types of noise in neurons and synapses which should strongly inhibit reliable signal transmission. |
| Not addressable | There is no position location system in the brain by which some exact neural location could be looked up by using its address, to achieve fast recall. |
| Signal-suppressive | A synapse in the cortex will transmit a signal with a likelihood of between .1 and .5, which means brain signals are constantly being suppressed. |
| Disorganized | Neurons are like the spaghetti mess in a huge cafeteria pot, and are not highly grouped into organizational units like letters in a book or computer components. |
| Indistinct | No one has discovered any distinctive marks or signs of encoded information in neurons or synapses other than the DNA information about the same in every cell. |
| Neither readable nor writable | No one has been able to specify how episodic memory information could be written to or read from neurons or synapses. |
| Largely dispensable | There are many medical cases of people suffering little damage to their minds or memory even though they lost very
much of their brains, as much as 50% or 75% or more. |
