The hippocampus is thought to respond to information that is being maintained in working memory in other areas. Areas that are commonly thought to maintain working memory include prefrontal cortex (reviews: Chai et al 2018 https://doi.org/10.3389/fpsyg.2018.00401) and entorhinal cortex (Fransen 2005; Egorov et al. 2002). For example, some information about ...

Except in three specific areas (olfactory bulb, dentate gyrus, SVZ) where neurogenesis continues to occur in adult organisms, it is virtually absent from everywhere else, including the cortex. However, there have been many reports that the grey matter of the cortex, i.e. the zone where cell bodies and their processes reside, can enlarge. Cortical expansion ...

The term for the brain activity that corresponds to an experience is "neural representation". Neural representations "drift" over time. From https://elifesciences.org/articles/51121: Similar ‘representational drift’ has been shown in other neocortical areas and hippocampus (Attardo et al., 2015; Ziv et al., 2013; Levy et al., 2019). So ...

If you want the function of the prefrontal cortex boiled down to a single coarse approximation, the answer is executive function. That notion of more structured and symbolic cognition encompasses pretty much all of the others on your laundry list. As with other complex and multifunctional organs in the body, reducing the prefrontal cortex in this manner is ...

@Bryan's answer isn't totally correct. Short Answer: There are different nerves. Motor neurons and sensory neurons are not identical and anesthesia affects them differently. When dentist inject novacaine they are targeting the V3 or V2 nerve trunks, where both sensory and motor neuron bundles are in close proximity. Take a look at this illustration for ...
