This is an entire website dedicated to human memory and how it works at the neuronal levels! It is inclusive of memory disorders and memory processes. Not quite related to what we read, but still pretty cool.
Claymation video of synaptic plasticity. In simpler terms, synaptic plasticity is the rearranging of neurons that can signal onto one another in order to increase brain function and to help create successful long term potentiation of signals (memory!)
Really cool primary research paper on fear conditioning! Worth the read if you are interested. We read this paper in one of my neurobiology classes in undergrad!
