Not an answer, but a clarification. By "hippothalamus" (a probable typo) above it is probably meant "hippocampus", as is mentioned in wiki link. It is hippocampus which is known "to hold memories", but it is a part of a larger "memory" circuit and is a bit similar to temporary memory responsible for holding only recent memories and integrating recent ...

It seem's you are assuming that your / the adult human brain produces new neurons over time- this is (largely) incorrect: neurons are non-dividing cells and are all formed throughout embryogenesis and very early childhood / infancy (see also this question). Only very exceptions to this are known as adult neurogenesis (generation of new neurons), the most ...

I interpret your question as essentially asking this: What is the effect of a limited diet on the gut microbiome? Can a limited diet affect the brain via the microbiome? To simplify the answer, let's make some assumptions -- This "limited" diet is nutritionally complete, meaning that it contains all the macro- and and micro-nutrients needed for human ...

(This is such a difficult question to begin answering in any satisfactory manner, though I think can be addressed for pedagogical purposes in line with the aims of this SE.) Before we address the question, I think it is prudent to think about the difference between stimulation and activity. A neuron can be self-activating without external stimulation, or ...

Humans have new auditory regions in the brain for predicting and processing speech, and processing the emotions conveyed in the voice. The human voice mostly has harmonics in the 3rd and 4th note due to the ...

So, let's use a neuron to neuron connection as an example. Calcium is released into the neuron when voltage gated ion channels, specific to calcium, open. These channels can only open when there is a significant depolarisation in the axon terminal of the neuron. Where do the calcium ions come from? The majority of them are outside of the cell by the ...
