Helloo people,
I'm backk.

Today's topic of discussion is Neurogenesis.

Neurogenesis is the process by which nervous system cells, which are neurons, are produced by neural stem cells. From the name, we can dissect that this is the case as -Neuro refers to anything about the nervous system, and -genesis is the origin or mode of formation of something.

Neurogenesis happens primarily in the hippocampus which is a region of the brain responsible for memory and learning. It happens to make more neurons which would be used for learning, memory, and adapting to new information as well as reducing emotional stress by improving brain resilience and brain repair.

Take this for example, The brain got tired of forgetting where it left the keys, so it started making new neurons. The old ones complained, but the new recruits didn’t remember why. And that’s why neurogenesis happens—because even your brain needs a refresh button!

Neurogenesis can be stimulated through:
  • Exercise as workouts such as running and swimming, increase brain-derived neurotrophic factor (BDNF), which promotes neuron growth.
  • Diet as foods rich in omega-3 (salmon, walnuts), flavonoids (dark chocolate, blueberries), and antioxidants support brain health.
  • Learning & Mental Stimulation as challenging your brain with new skills, languages, or puzzles enhances neurogenesis.
Now the relationship between neurogenesis and neuroplasticity, our last discussed topic, so I don't seem like I am spamming you with information that does not even relate is:
  • Neurogenesis creates new neurons.
  • Neuroplasticity is the brain's ability to rewire and adapt by forming new connections.
  • New neurons from neurogenesis enhance plasticity, improving learning, memory, and recovery from brain injuries.

So, neurogenesis fuels plasticity, and plasticity ensures those new neurons are put to good use!

Thank youu all for reading, until next time.

 Helloo you all once again, just to dive right into it (I'm afraid to say anything else cause yk I haven't been here in a while so I don't want to anger you guys more...😁) we will be talking about mirror neurons ! Okay, so here's something wild—your brain has these things called mirror neurons , and they might be the reason you wince when you see someone stub their toe or why watching a sad movie actually makes you feel something. Discovered back in the '90s (by accident, of course—shoutout to scientific chaos), mirror neurons are a type of brain cell that fire not only when you perform an action, but also when you watch someone else do it. So, if you see someone lift a cup, your brain lowkey mimics that movement internally.  But it’s not just physical actions. These little guys might be deeply tied to empathy, social bonding, and even learning. There’s research suggesting that mirror neurons could be part of why we’re so good at understanding facial expressio...

  Hello guys, it has been a while.... I know I said I’d post about the last week of December, and it’s been almost a month now, but I’m back, yay! Today I just came to share something with you guys that you may have known but if you didn’t and are learning about it today like I did, here it is. It is something called neuroplasticity , it is the brain’s capacity to change and adapt in response to new things like learning skills or injury mainly being active during the years of 5-21 years old as those are the years where activities such as those stated happen more frequently. It involves making new pathways in the brain, allowing us to experience and recover from those injuries. For example, let's say I hit a table corner as I was walking towards it. That is a painful experience and something I would not want my body to go through again, so my brain creates these neural connections. The next time I walk in the direction of a table corner, I will know not to walk directly toward...
