Some Kongfu guy trying to show the spirit of the school. It was rather funny though.
To physiotherapy Department!
World Class. Be part of it. "Touching life, making an impact"
Top course in our university. Full employment. Extreme stimulation.
Our cardiopulmonary room!
That's where I was stationed and hence all pictures were taken in here. heehee
1.Graduating student demonstrating suctioning.
2.Dr Jack Lai explaining neuro stuffs to Raymond at the spirometry station.
3.Anatony explaining postural drainage on babies! That's my station! ^^
4.Shadow explaining about Breath sounds.
Shadow and Me! ^^
1.Us with our respective models.
2.Bronchial of the lungs!
3&4. Us performing auscultation!
Shots with friends. ^^
1.KY and Grace.
2.Me and KY.
3.Me and Howah
4.Me and yr 1 Mandy.
Model of the Cardiopulmonary system!
I love models! I hope I can do one on my own. :D
Chest X-ray station.
Grace covered with blanket. :P
The Finale. ^^
This morning, I dropped by Neurolab for to finish up the drawing for my brain while Doctor He gave us a stimulating talk about the brain.
He emphasized the fact that we actually need at least 12 hours of sleep in order to repair our brain each day. However, with the invention of light, all humans have been getting sleep deficient! Moreover, with the advancement of new technologies, we continues to have an increase in lifespan despite the unknown damage we are causing our brain. This actually explains for the increase of the number of neurological problems arising in recent decades. The signs and symptoms can include a bad memory and loss of reflexes when we are old. Yet, humans have always thought that it is a normal sign for aging. If damage is done to the cortex, Dr He mentioned that it could still be fine as we could still survive without some motor and sensory function, however, if damage is done to the limbic system; we could fall into medical conditions like depression that could actually affect our survival on Earth.
So sleep more! Be nice to our neurons in our brains! ^^
:D
Another masterpiece of mine!
Horizontal view of Section 5 of the brain.
Memories are actually stored between synapses in the cortex.

haha according to my limited understanding, memory is stored in a form of electrical signals called 'long term potentiation' in our neurons. basically what happens is, let's use spatial memory as an example - the visual cortex feeds the information to the hippocampus, and somehow the neurons transduce the signal as a form of high-frequency action potentials to the synapse there. the pre-synaptic membrane would then release glutamate into the synapse, first opening an AMPA receptor, allowing Na+ to enter the post-synaptic cell, releasing the Mg2+ ion blocking the NMDA receptors, opening the NMDA receptor, allowing Ca2+ influx. The influx of Ca2+ activates calmodulin, which activates CaMKII, which is a protein that has a BUILT-IN memory function (i won't describe the molecular details - it'll take too long) - and sustained CaMKII activation will cause it to phosphorylate the AMPA receptors at the C-terminal, holding the channel open, thus sustaining the depolarised state of the posy-synaptic membrane - and that is basically 'memory'. The opposite happens when we forget things. This model is based on a 2003 Johns Hopkins study using mouse as the model :D
(LOL maybe i'm mad, but this is the kind of thing that i love... :D)
