Pregnant Women Fit Between Everyday Obstacles

February 10th, 2014 in Article, News, Pop Culture, Uncategorized 1 comment

Pregnant
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.

The Polygenetic Basis of Mutations in the Development of Schizophrenia

February 9th, 2014 in Article, News, Uncategorized 0 comments


Schizophrenia is a mental disorder often presented in patients by abnormal thought processes, impaired emotional responses, and negative symptoms. As a chronic disorder that affects ~1% of all people, schizophrenia can be have debilitating effects on patients, especially on their social lives. Due to the lack of knowledge on its pathophysiology and also the heterogeneity of the symptoms, it has been increasingly important to understand the genetics of schizophrenia.

Due to the marked reduction in fecundity seen in schizophrenic patients, the high heritability of the disorder pointed to the possibility that genetic alleles that were risk factors might occur as de novo mutations. Previous exome sequencing studies showed no promising results, but the inconclusive results were likely due to small sample size and a narrow focus on target genes. Two recent studies, the largest of their kind, gathered data from nearly 7000 people (nearly 3500 patients) from Sweden and Bulgaria, and showed that genetic effects on schizophrenia seemed to be very complex. Specifically, both papers published in Nature reflected on the implication of genetic mutations in clusters of specific proteins that governed signaling networks dealing with learning and memory. The studies identified the presence of de novo mutations, often nonsense mutations, notably in genes related to the PSD (post-synaptic density of dendrites), the calcium channels, the postsynaptic ARC complex, and the NMDA receptors.

The Power of Meditation

February 8th, 2014 in Article, Pop Culture, Uncategorized 3 comments

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.
Meditation
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.

Traumatic Brain Injuries: Helpless to Hopeful

October 10th, 2013 in Uncategorized 0 comments


Helmets are a good thing!Traumatic brain injuries, often referred to as TBI, have  gained major traction in the field of neuroscience over the past couple years, and for obvious reasons. The name itself suggests that something has gone horrible awry with our BRAIN – you know, the mass of cells inside our skulls responsible for telling our heart to pump and our muscles to contract, the organ that controls all of our cognitive abilities and complex processing, that space between our ears that has been associated with creating the somewhat vague concept of our mind? It’s not surprising that neuroscientists have deemed it important to begin researching ways to at least partially remedy the potentially devastating effects of an injury to our most central organ.

Previous TBI research hasn’t exactly led to the most uplifting results. While research has advanced enough for us to be able to visualize TBIs and generally understand the symptomology of TBI, the field has lagged in suggesting potential therapies for patients with this condition. The broad view has always been that patients with TBI improve up to a certain point, and then they plateau, staying at a consistently impaired state – until now.

Telepathic rats communicate via brain-to-brain connections

March 8th, 2013 in Uncategorized 0 comments


Scientists from Duke University and Brazil claim wires connecting one rodent to another can allow communication spanning continents via the internet. Professor Miguel Nicolelis of Duke University in Durham, North Carolina, led a team of researchers who demonstrated that it is possible to transmit instructions from one animal to another by brain-to-brain communication, a process akin to telepathy.

Brain-to-brain communication could be the start of  organic-based computing based on networks of interconnected brains. Pairs of laboratory rats were able to communicate with each other using microscopic electrodes implanted into their brains. This occurred as part of an experiment where the two rats had to work together in order to receive a reward (see video at source).

Liar Liar, Pants on Fire, Hanging from a 75th Percentile Wire

February 15th, 2013 in Uncategorized 0 comments


Do you remember telling a lie at 2, 3, or 4? Well, feel guilty no more! Lying is actually a reliable sign of higher cognitive functioning. It was previously accepted that children were able to start lying at 3.5 years and no earlier. However, a recent study by psychologist Angela Evans found that 25% of two-year olds, 50% of three-year olds, and 80% of four-year olds were capable of lies.

Want to Bolster STEM Career Interest? This Guy's Got it Right.

February 6th, 2013 in Uncategorized 0 comments


Here’s a great TED Talk to get everyone thinking today.

Tyler DeWitt at TEDxBeaconStreet

Tyler DeWitt is a PhD candidate at MIT and an advocate of the idea that science education in high schools needs to take a turn for the less serious if we want kids to really get excited about it. Instead of the highly technical jargon of textbooks, he is in favor of turning science lessons into storytelling. “Science has become that horrible storyteller…who gives us all the details nobody cares about,” DeWitt says, and his goal is to change that. DeWitt also has a growing library of YouTube videos aiming at exposing students to topics in biology, chemistry, physics, and math in a fun, engaging, and (perhaps most importantly) relatable way.

Happy Holidays!

Pretty music with pretty pictures: all of our brains love that (nothing new to neuroscience there)! Have a fantastic holiday season everyone!

 

 

 

 

The Soundtrack of the Human Brain

December 8th, 2012 in Article, Arts + Media, Uncategorized 0 comments


Neuroscience researchers in China have created a method of transforming brainwaves into music by combining EEG and fMRI scans into sounds that are recognizable to human beings. The EEG adjusts the pitch and duration of a note, while the fMRI controls the intensity of the music.  According to Jing Lu and his associated colleagues from the University of Electronic Science and Technology in China,  this brain music, “embodies the workings of the brain as art, providing a platform for scientists and artists to work together to better understand the links between music and the human brain.”

Applying EEG and fMRI data to make better music represents the limitless opportunities of the brain, potentially leading to improvements useful for research, clinical diagnosis or biofeedback therapy. In fact, researchers at the Department of Homeland Security’s Science and Technology Directorate have already looked at a form of neuro-training called ‘Brain Music’, which uses music created from an individual’s brain waves to help the individual move from an anxious state to a relaxed state.

“No Brain? No Problem!”

…Says the slime mold before the zombie ate its brain centuries ago, forcing the whole species to adapt into its present state: brainless yet smart.

Slime molds avoid bright light. In A, there was none, so molds grew to food (yellow puncta) freely while in B and C there were differing shades of light to influence its growth, which is surprisingly comparable to the real Tokyo rail network in D. E and F show minimum spanning trees (see third source below).

Okay, the zombie part isn’t entirely accurate, BUT, these slime molds (the gelatinous amoebae also known as the protist, Physarum polycephalum) do seem to have no problem functioning without a brain. They can navigate complex mazes for food, choose healthy over less nutritious food, and determine the shortest route between points of interest – a feat that takes humans years when designing complex transportation systems. How could this be? More
