Neuroscience: Amateur Hour

Dreams are both scientifically fascinating and universal. Everyone dreams, at every age and they are often nonsensical, complex, and deeply subjective. How can you quantify something so personal in the activity of cells, circuits, and systems? Let's find out together!

A tragic incident - a brain injury, a stroke, the development of a neurodegenerative disease, and all of a sudden, a patient's arm no longer belongs to them. It will pull their hair, pinch their cheeks, and grab miscellaneous objects, seemingly developing a mind of its own. How can something that belongs to you and is controlled by your brain, your electrical pulses, and your motor neurons ever develop a mind of its own? Listen to find out more!

Hello! I return! Today we will be talking about the neuroscience of seizures and epilepsy. Brought about an imbalance of the accelerators (excitatory circuits) and brakes (inhibitory circuits) of the brain, seizures are pretty terrifying events. They're marked by temporary confusion, a staring spell, uncontrollable jerking of the arms and legs (like what you see when someone depicts a seizure on gray's anatomy), loss of consciousness, or even some cognitive and emotional symptoms. Curious to find out what the heck the brain is up to during seizures? Come and listen to find out more!

Today’s episode is inspired by a historical nightmare and the subsequent decades-long experiment that shaped the way we understand childhood neglect and its effects on the developing brain. In 1989, Romanian dictator Nicolae Ceausescu was overthrown and the rest of the world discovered that over 170,000 Romanian children were being kept in impoverished institutions and orphanages. These children were raised, not by loving parents or guardians, but by the metal bars of their beds and impersonal nurses. This neglect resulted in severe, lifetime, neurological issues including altered structure, function, and connectivity among different brain regions important for integrating complex information, including cognitive, social, and emotional competencies. Curious about the decades-long project that followed these children for 21 years and documented the adverse effects of neglect on the developing brain? Come and take a listen!

This week we will be learning about bipolar disorder! It's a condition characterized by extreme mood swings from emotional highs to emotional lows. One week someone may end up sleeping 24 hours straight and the next week go on a $10,000 gambling spree in Vegas.

Welcome back! This week, I want to talk about your ears and how going to super loud concerts can impact your ability to hear. You might be thinking wait - ears aren’t brains. But the way we process sound in our ears is a part of the peripheral nervous system so I say close enough! Come and listen to learn a little bit more about your auditory system, your peripheral nervous system, hair cells, and the absolutely insane feat of biological engineering that allows for sound to go from your surroundings to your brain.

Social media is omnipresent. Mindless scrolling through TikTok and Instagram reels is just a part of our daily lives now. Whether it's cat videos, funny dances, or cool outfits, online content fills our excess time, entertains us, and keeps us connected with our friends and the people we look up to. As my housemate says, sometimes, we’re living in the REEL world, not the REAL world. But it's also no secret that too much social media is not very good for our psyche and our brains. Curious why?

It's linked here: https://www.biorxiv.org/content/10.1101/2022.02.01.478733v1 This episode is structured so that I chat through the paper, citing specific figures and discussing them in detail.

When I was a kid, I thought two things were going to be much bigger problems in my life than they actually are - quicksand and mad cow disease. Turns out that they aren't but mad cow disease is still the stuff of science-fiction nightmares. Mad cow disease is caused by the spread of prions, proteins that weaponize our own cells against us and cause proteins to misfold and aggregate, slowly killing neurons throughout the brain. The disease is characterized by rapid and fatal neurodegeneration. Want to get the shit scared out of you by learning about the truth behind mad cow disease? Come and listen!

For the low, low price of $15.95 on Amazon, you can purchase a little spray bottle of pheromones that supposedly will trigger "animal attraction" in your partner. But is it true??? Pheromones are a well-known system of communicating territory, alarms, and sexual needs to other animals but is this system present in humans? We know that smell is an important component of sexual attraction and arousal but human beings seem to lack both the organ and brain region needed to process pheromone information. But maybe???
