Maybe Glaucoma? But maybe a convergence deficit after brain injury?
I was hit-and-run by an SUV, my skull split open, and I broke all the bones in both my eye sockets which negatively impacted my vision. Recently at an eye doctor, they tested my eye pressure and said I was possibly on the verge of glaucoma. But possibly my brain damage, broken eye sockets, and 'convergence deficity' also can impact the eye pressure and look like glaucoma?
Are there negative long-term effects of losing your sense of smell?
Like many others, I have lost my sense of smell in recent years. I would estimate my sense of smell has recovered about 10% - 15%. I have recently been told that losing your sense of smell can cause your hippocampus to decrease in size. Is there any specific research on the adverse effects of losing your sense of smell? Also, would it be beneficial for my long-term health to retrain my smell capabilities? Thanks!
Enhancement of Memory by Catecholamines Across an Extended Learning Session
Hi Andrew, In your episode, "Understand & Improve Memory Using Science-Based Tools", you explained how a spike in catecholamines immediately following a learning episode can enhance memory consolidation. From what I have seen, the studies that have looked at this have used very short learning episodes and have found that the spike in catecholamines is best induced immediately after learning and has diminishing effect if induced later. I am wondering how this would apply to a longer learning episode, such as a 90-minute session, which I have adopted with great benefit from your episodes on focus. Intuitively, for a learning episode of this length, a spike in catecholamines immediately following the bout of learning would improve learning of the material studied right at the end of the session but would have diminishing effects on enhancing memory of material studied earlier in the session. I could also see an argument for consuming caffeine or another stimulant at the beginning or middle of the session to enhance learning of all material studied while the effect of the stimulant is rising to its peak, rather than just the material at the end of the session, if the stimulant is taken after the session. Could you please clarify how spiking catecholamines could be best used to enhance an extended learning session or point out any studies that have experimented with extended sessions? Thank you for fostering our interest in science, Max
