I think I’m funny. Some people say I’m funny. But when the moment presents itself where its my time to shine, all lights on me, this ‘one’ is going to be a knee slapper…nope, not so much. The first time I realized I wasn’t funny was in the eleventh grade in my calculus class. My teacher’s name was Mr. Butke and he easily is ranked in my top 3 ‘all-time’ of the math professors I’ve encountered in my lifetime. He had a mustache that covered his mouth and you never knew whether he was smiling, smirking, or grimacing at you. It kept you guessing, I liked that. He also presented stories of how he slayed cobras in Kenyan villages while pursuing a multi-purpose cure for malaria, encephalitis’ of sorts, and maybe AIDS. Bottom line, he was memorable and his stage presence resonated with my classmates and I.
We all know that sleep is one of the best ways to restore our body. For example, when we become sick, we just lie in bed and sleep all day; or after a long day bustling between class, the gym, meetings, and extracurricular activities, our body yearns to fall into a deep slumber to restore itself to its peak state. Recently, it was published that the reason sleep is so restorative is because while we sleep, cerebrospinal fluid flows more efficiently through the brain, essentially “clearing” the brain of any metabolic waste products that build up during the day (for more on this, refer to the December 9th blog post). However, just as we all understand that great feeling of satisfaction that comes after the so rarely obtained 8-9 hour sleep cycle (yes, young college-aged adults should ideally be getting 8-9 hours of sleep a night), we also can all relate to the groggy, confused, cognitively impaired state that comes after the all-night cramming and three hours of sleep, and before the double espresso from Starbucks. Until recently, this chronic state of unrest considered normal by college students, shift workers, and truck drivers, wasn’t thought to have any long lasting damage; it was considered common knowledge that catching up on sleep during weekends or vacations made up for the hours of sleep lost during finals week. However, a new study published on March 18th in the Journal of Neuroscience refutes this; the study, out of University of Pennsylvania’s Perelman School of Medicine, shows that chronic sleep loss may be much more destructive than previously thought, leading to permanent cell damage and neuronal death.
How many times have you not completed the reading assignment for you systems physiology class because you ran out of time? How many times have you attempted to use speed reading techniques like not subvocalizing, or talking to yourself as you read? A new Boston-based start-up claims to have solved the ‘slow reader’ problem and promises 600 words per minute for all.
One must be skeptical when approaching the front line technologies, as it is easy to be convinced that people have invented what you desire. For instance, when Tony Hawk promotes a brand “hoverboard” technology, Back to the Future fans went berserk. However, Spritz is a bit more open about the actual science behind their product.
It would make sense for kissing to be favorable for evolution if it led to increased arousal and consequently a greater inclination to have sex. When a (heterosexual) couple is kissing, testosterone can pass from the man’s mouth to the woman’s, which may make her more receptive to sex (and the passing on of their genes). But it turns out that though people certainly kiss when they’re aroused, there’s not much evidence to suggest that it works the other way around, where kissing causes arousal. And though some other species such as bonobo monkeys also kiss, it doesn’t have quite the same association with sex as it does for other humans. This suggests that there are other factors at play than just the initiation of play time.
As an international student living in the U.S., one always misses their native country. Whether it be the food, the house, the parents or the friends, homesickness is a normal feeling. As strange as it may seem, my dog Baco is who I miss the most. Baco is a 3-year-old Rhodesian Ridgeback. For those non-dog lovers out there, a Rhodesian Ridgeback is quite frankly the most beautiful, loyal breed of dog (no exaggeration). Baco has been like my fourth brother ever since my actual brother brought him home as a puppy. Together with my brother, we raised him since he was no more than 5 kilos (that is about 11 pounds for those who do not understand the metric system). Today, Baco stands at about 66 cm tall (about 2 feet) and weighs about 34 kilos (75 pounds). You might be wondering why I am bragging about how great my dog is in a neuroscience blog. Well, in the past few years, some very interesting research about the canine brain has been done…
I have always wondered if Baco truly loves me or if he just acts as though he loved me in order to get food. Like me, I imagine there are millions of dog owners who may ask themselves the same question. Interestingly enough, one such dog owner is recognized neuroeconomist and neuroscientist, Gregory S. Berns. Professor Berns and his team have been studying the dog brain for a while now, and there research has been nothing short of extraordinary. I found out about this research by reading Berns´ book, “How Dogs Love Us.” Of course I want everyone who reads this article to read that book so I will try not to spoil it for you.
Pregnancy is…? This sentence can end in a multitude of ways depending on whose answering the question. If I ask the ‘teen-mom-too-good-to-be-true-seventeen year-old-boyfriend’ who isn’t worried about nothing, then he’d probably say…well I would’ve asked but he just stormed off in his 92′ Bronco. You know, the one with the flames on the side? If I ask the nervous husband who has been day dreaming of becoming that perfect family man ever since he got into the relationship, then he’d probably say: If it’s a girl, I will be the dragon that protects my princess’ castle. If I ask the soon-to-be-BIG-brother whose busy doing doughnuts in his fisher price corvette yelling “look mom, no hands,” he’d probably say: This doesn’t change the cookie rations, does it? And finally if I ask the pregnant mother-to-be
if she thinks she’s gained weight what she’s praying for, she’d probably say: Just not your father’s personality, PLEASE, not your father’s personality.
Pregnancy is engaging. It brings together families, can tear relationships apart, and creates changes in the daily routine. Most notable is women’s change in body size. Bodily size and the awareness of that size can create multiple obstacles. Typically, pregnant women are thought to be inhibited in their ability to adapt to these obstacles, however, pregnant women are just as capable as non-pregnant individuals. Today, we’ll discuss their ability to asses depth perception and whether or not they can fit through openings such as doorways. Thanks to perceptual-motor-recalibration, pregnant women are just as good at adjusting their spatial awareness of their environment to match their constantly changing bodies.
When the word meditation comes up, people usually think of Monks or Buddhists first. However, there is a reason they meditate so often; meditation does wonders for your brain, and here is how.
There are two main types of meditation: 1) Focused-attention meditation or ‘Mindful meditation‘ and 2) Open-monitoring meditation. In Mindful meditation, you focus on one specific thing ranging from your breathing, a specific sensation in your body, or a particular object in front of you.The key point is to focus on one thing without consideration to other thoughts or events happening around you. When any distractions occur, you must be quick to recognize it and turn your focus back to your focal point. Open-monitoring meditation is where you pay attention to all the things happening around you but you do not react to them.
As we grow and discover new artists, we refine the compilation of music in our brains. But do we stop developing taste in music at a certain age? Many researchers believe that by the age of 14 musical preferences are completely developed. Does this mean that your taste in music is set in stone for the rest of your life? Not exactly.
In an article from the New York Times, David Hajdu points out that major music stars such as John Lennon, Paul Simon, and Aretha Franklin, and many other successful artists all turned 14 during the mid-50s, when rock ‘n’ roll was first becoming a major genre. Altough it may just be a strange coincidence, Hajdu believes that this is what influenced them to pursue music as a career “Fourteen is a sort of magic age for the development of musical tastes,” says Daniel J. Levitin, a professor of psychology and the director of the Laboratory for Music Perception, Cognition and Expertise at McGill University. “Pubertal growth hormones make everything we’re experiencing, including music, seem very important. We’re just reaching a point in our cognitive development when we’re developing our own tastes. And musical tastes become a badge of identity.”
Does the gym seem too far away? Do you feel like you don’t have time to exercise? There may be some good news for couch potatoes like ourselves. Studies are showing that watching a sport causes some of the same physiological effects as actually working out . While watching others exercise, heart rate, respiration, skin blood flow, and sweat release all increase as if you were exercising.
Researchers at the University of Western Sydney inserted fine needles into an outer nerve of volunteers who were shown a static image followed by a video of a jogger for 22 minutes. With these needles, the scientists were able to record electrical signals within nerve fibers that innervate blood vessels. These recordings provided measures of the body’s physiological stress response, particularly muscle sympathetic nerve activity.
The study showed that sympathetic nerve activity increased when volunteers watched the jogger. In comparison, observing the static image caused change in activity. The sympathetic nervous system innervates the heart, sweat glands, and blood vessels, and its activity increases during exercise. This study indicates that its activity also increases while watching another person exercise, indicating that there may be some benefit.
Before reading this post, I want you to take a look at the website of Bryan Lewis Saunders, specifically the portion that describes his escapade through drugs and self-image. It can be found at http://www.bryanlewissaunders.org/drugs/.
As a brief summary, Saunders took one drug a day for several weeks straight, and drew a self-portrait during the experience of each. Eventually, he changed to more sporadic use due to exhaustion and brain damage issues, but he did continue for quite a while. Saunders ranges the gamut from commonly known drugs such as Adderal, bath salts, and cocaine to more obscure Risperdol and Klonopin. The approach was clearly unscientific, it does delve into some interesting questions concerning our self-image, at least once you go past the initial, “this guy is crazy” response. Although I certainly won’t delve into all of them, I think it’s important to sometimes take a moment and ask them.
First of all, it’s interesting to see how much our self-perception can be altered by something so seemingly trivial as a drug. We consider our image to be an integral part of us, yet it is easily changed. For those who study neuroscience, this is probably unsurprising, as we know that drugs change the chemistry of our body and brain, and are thus likely to alter self-image. However, the extent is quite amazing, if Saunder’s pseudo-experiment is any indication.
