In addition, priming (both perceptual and conceptual) can assist amnesiacs in the learning of fresh non-declarative knowledge. People can learn new procedural knowledge. However, a severe reduction in the ability to learn new material and retrieve old information can be observed.
In people with amnesia, the ability to recall immediate information is still retained, and they may still be able to form new memories. Scientists were able to find that mice with damaged memory have a lower level of RbAp48 protein compared to normal, healthy mice. Recent studies have shown a correlation between deficiency of RbAp48 protein and memory loss. Research has also shown that when areas of the diencephalon are damaged, amnesia can occur. In addition, specific areas of the hippocampus (the CA1 region) are involved with memory. ▼ AmnesiaĬase studies also show that amnesia is typically associated with damage to the medial temporal lobe.
