For many of us, laughter is fundamental to expressing ourselves and connecting with others. Long before babies learn to talk, they laugh. But a baby’s laughter is different than that of an older child or adult. As scientists recently discovered, the laughter produced by young babies actually sounds more like a chimpanzee’s laughter than an adult human’s.

Human laughter is unique among apes, and a challenge for young babies

While humans over the age of two only laugh while exhaling air, non-human apes like chimpanzees often laugh during both exhalation and inhalation. Scientists have proposed that human laughter evolved from this ape-like type of laughter that mixes exhalation and inhalation. But as our ancestors’ social behaviors and communication evolved, so did their…

The Neurobiology of Human Intelligence

Very insightful, loved reading it!

Understand (verb): to stand in the midst of, among, between.

Intelligence (noun): from the Latin words, inter (between), and legere (choose).

First things first – mushrooms

It was Charles Darwin who wrote that intelligence is based on how efficient a species becomes at doing the things it needs to survive. If that is the case, then the 2.5 billion-year-old fungi are undoubtedly the most intelligent organisms on Earth. Most think that fungi just make mushrooms, but the unrelenting growth of fungal stems (hyphae) which are five times thinner than human hair, and the enzyme cocktail they excrete, is enough to shatter the hardest rock repeatedly, creating the first soils in a bare landscape. In addition, fungi hold that soil in place with their dense root-like net (mycelium).

Fungi shaped and guided the force of life on Earth

It is fungi who helped pave the way for modern plants and animals…

Human Anatomy

S.P.A.S.C

Human anatomy is the study of the structure of the human body. As a Year 1 physiotherapy student, anatomy is a really important module which you should pay attention to.

For semester one, you will usually start with the upper limb. Anatomy is quite important as it forms the foundation for other modules such as kinesiology. This module is challenging and sometimes can get a little bit painful and confusing. But with knowledgeable and approachable lecturers, you would certainly find yourself enjoying learning anatomy.

Human anatomy module is divided into theory (in the form of lectures) and practical classes. It is one of the most difficult classes that require endurance. To help you get through human anatomy classes, I am going to share some tips and tricks with you guys.

How I survive Human Anatomy?

Muscle Recruitment Patterns and Discharge Rate

Posterior view deep inside our muscles ……

Opening our Minds - Interpersonal Communication

One of the most important philosophical/physiological aspects is to understand the utilization of the discharge rate/sequence. The discharge rate is the progressive recruitment and activation of our motor units within our muscles. In order for an action or exercise to be effective, we must fire from the smallest to the largest motor units. From a anatomical perspective, we should fire our transverse abdominis before we fire our obliques or rectus abdominis. The transverse abdominis is one of the main stabilizers of our core/spine and therefore we must activate it first before we turn on the larger heavier muscles. It only makes sense doesn’t it? If we do not stabilize or brace ourselves for the action before the prime movers (main delivery muscles that will “do” the exercise) are activated then there would be varying degrees of output along with possible awkward delivery of an exercise due to earlier fatigue. This…

New Discoveries Inside The Developing Brain

The human brain develops with an exquisitely timed choreography marked by distinct patterns of gene activity at different stages from the womb to adulthood, report Yale researchers. The Yale team conducted a large-scale analysis of gene activity in cerebral neocortex —an area of the brain governing perception, behavior, and cognition — at different stages of development. The neocortex, Latin for “new bark,” is our third, newly human brain in terms of evolution. It is what makes possible our judgments and our knowledge of good and evil. It is also the site from which our creativity emerges and home to our sense of self.

The team found that the human brain is more like a neighbourhood, which is better defined by the community living within its borders than its buildings.“The neighborhoods get built quickly and then everything slows down and the neocortex focuses solely on developing connections, almost like an electrical grid,” said…

A research team at Northwestern University are studying the connection between memory and sleep, and the possibilities of boosting memory storage while you snooze.

For the first time, scientists have used a new combination of neural imaging methods to discover how the human brain adapts to injury. The research, published in Cerebral Cortex, shows that when one brain area loses functionality, a “back-up” team of secondary brain areas immediately activates, replacing not only the unavailable area but also its confederates.

New research suggests that testing a portion of a person’s saliva gland may be a way to diagnose Parkinson’s disease. The study was released today and will be presented at the American Academy of Neurology’s 65th Annual Meeting in San Diego, March 16 to 23, 2013.
