The Blood-Brain Barrier and Neurogenesis
19:03 - 26:59 (07:55)
This episode discusses the blood-brain barrier and why it is difficult for substances to pass into the brain, as well as the rate of neurogenesis in humans and where it exists.

The blood-brain barrier is a highly selective membrane that prevents substances from entering the brain unless they are small or critical for brain function.
19:03 - 23:01 (03:57)
Summary
The blood-brain barrier is a highly selective membrane that prevents substances from entering the brain unless they are small or critical for brain function. While neurogenesis exists in some animals and humans, the majority of research suggests that there is not much neuron turnover in humans due to natural cell death called apoptosis during development.

The OVLT (Organum Vasculosum Laminae Terminalis) is a region of the brain that regulates fluid balance and thirst by detecting changes in the bloodstream and setting off cascades of events that make you want to drink more or less fluid.
23:01 - 26:07 (03:05)
Summary
The OVLT (Organum Vasculosum Laminae Terminalis) is a region of the brain that regulates fluid balance and thirst by detecting changes in the bloodstream and setting off cascades of events that make you want to drink more or less fluid. This region is critical for proper brain and neuron function, making it important for overall health and survival.

Osmotic thirst is caused by an increase in salt concentration in the bloodstream, which triggers a feeling of thirst.
26:08 - 26:59 (00:51)
Summary
Osmotic thirst is caused by an increase in salt concentration in the bloodstream, which triggers a feeling of thirst. Ingesting salty foods can cause an increase in sodium levels, leading to osmotic thirst.
