neuroscience!!

I’ve been buying quite a bit of non fiction lately, mostly books on neurology and neuropsychology because I find them fascinating. I’m currently reading Reaching Down the Rabbit Hole which is a series of case studies as told by a Neurologist from his time working at Harvard Medical School neurology unit. I’m actually really enjoying it!

Welcome to my studyblr! This is my first original post on this blog and I’m really excited for the new year :) These are some of my notes from my neuroscience class last semester and I’m kind of sad that it’s over because brains are cool dude (I’m a prospective neuroscience major so more brains in the future~).

Feeling motivated and pretty good today, I want to pass that exam on Wednesday as good as possible ✨ I do love mildliners, they are gorgeous (even though they last for 2 months 😞) but I’m so motivated just by using them ☀️ I hope you’re motivated and happy and y'all going to rock your exams 💪🏼💪🏼💪🏼

Life from the perspective of colour blind people 

Deuteranomalia: This is caused by reduced sensitivity to green light. Deutan color vision deficiencies are by far the most common forms of color blindness. This subtype of red-green color blindness is found in about 6% of the male population, mostly in its mild form deuteranomaly.

Protanopia: Caused by a reduced sensitivity to red light due to either defective or a lack of long -wavelength cones (red cones). Some scientists estimate that being a protan is associated with a risk of a road accident equivalent to having a blood alcohol level of between 0.05 and 0.08 per cent.

Tritanopia:  People affected by tritan color blindness confuse blue with green and yellow with violet.  This is due to a defective short-wavelength cone (blue cone). Whilst  Protanopia and Deuteranomalia are significantly more common in men, tritanopia affects both sexes in equal amounts.

Monochromacy: Only around 0.00003% of the world’s population suffers from total color blindness, where everything is seen in black and white. 

Avoid some of the Main Brain Damaging Habits

1. No Breakfast – People who don’t eat breakfast have lower blood sugar levels. This can lead to an insufficient supply of nutrients to the brain (and to underperformance in terms of thinking, processing , retrieval and memory skills).

2. Overreacting – This can flood the brain with chemical which interferes with clear thinking, logical analysis and memory.

3. Smoking – This can cause a shrinkage in the brain, and possibly lead to Alzheimer’s disease.

4. High Sugar Consumption – Consuming too much sugar interferes with the absorption of proteins and nutrients. These are essential for healthy brain development.

5. Air Pollution – The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain. Again, this can reduce and interfere with the brain’s healthy functioning.

6. Sleep Deprivation – Sleep allows our brain to rest and rejuvenate itself. Long term sleep deprivation accelerates the death of brain cells. It interferes with putting down new memory traces, effective problem solving and memory retention.

7. Exercising your Brain in Times of Illness – Working or studying during times of sickness can lead to a ineffective thinking, poor processing, and to poor memory and retention.

8. Lack of Stimulation – Thinking is the best way to train our brain. Lack of stimulation can prevent new neural pathways from forming. It can also prevent us from reaching our potential in terms of creative thinking and analytical thinking. Source: The World Health Organisation

Productive day today! Biology revision and I did a lot of reading 📖 today. One more class today, then I’ll try to finish my essay. I also bought 3 new books (I already read circle, but I just borrowed it) I’m looking forward to read thinking, fast and slow, I need to finish my English lectures first😧 Hope y'all having a good day and a good time!☀️

Scientists have pinpointed the ticklish bit of a rat’s brain.

The results, published in the journal Science, are another step toward understanding the origins of ticklishness, and its purpose in social animals.

Although virtually every human being on the planet has been tickled, scientists really don’t understand why people are ticklish. The idea that a certain kind of touching could easily lead to laughter is confusing to a neuroscientist, says Shimpei Ishiyama, a postdoctoral research fellow at the Bernstein Center for Computational Neuroscience in Berlin, Germany.

“Just a physical touch inducing such an emotional output — this is very mysterious,” Ishiyama says. “This is weird.”

To try and get a handle on how tickling works, Ishiyama studied rats, who seem to enjoy being tickled, according to previous research. He inserted electrodes into the rats’ brains, in a region called their somatosensory cortex.

9.7 it’s ya girl fresh from her first ever college class!! it’s probably a good sign that I fell in love with it immediately, as it’s the first requirement in my bio/neuro major :)) I also decided to go with a normal planner this year sadly, a bujo just took too much time to keep up with and I’m going for efficiency!!

Have you ever wondered??

abstract science → neuroscience

the scientific study of the nervous system. Traditionally, neuroscience is recognized as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, cognitive science, computer science, engineering, linguistics, mathematics, medicine (including neurology), genetics, and allied disciplines including philosophy, physics, and psychology.
