Muscle flexion and extension. How does it happen?
Muscle Flexion and Extension Did you ever wonder how body movement happens? Or what is a reflex arc? Or how a motor neuron transmits electrical impulses? I always wondered how our bodies function. Always wanted to know how and why things happen, from the molecular level to the organic and systemic level, all being just…

Read MoreOther Curiosities about the Human Brain
Did you know that the frontal lobe is the last part that evolves in our brain, the slowest to mature and the first to deteriorate as we age? How curious is that? It allows us to travel to the future before the actual experience takes place. Did you also know that the visual cortex is…
Read MoreAlexithymia – Absence of Words to Describe Emotional States
Alexithymia – a dissociation between experience and awareness is affecting people that seem to have feelings but they are somehow unaware of them. That is to say when awareness is decoupled from emotional experience, what we get is numbfeel. People can be happy, curious, sad, bored and not know it. They seem to have physiological…

Lost and Found Department – Spatial and Kinesthetic Perception – Creating Maps The parietal lobes govern spatial and kinesthetic perception. The somatosensory cortex – located on each side of the brain (the front part of the parietal area in the midline of the brain, running from the top of the head to each ear) –…

“The Woman Who Changed Her Brain – and other inspiring stories of pioneering brain transformation”, (by Barbara Arrowsmith-Young) which made her more understanding of the world she lives in altogether as well as more insightful and wise. (I take this opportunity to thank my friend, Wanda, who was so nice and inspired 🙂 to lend…
Read MoreThe Cerebral Cortex and its Convolutions
Cerebral cortex (mainly composed of small, unmyelinated neurons) is gray and it is often referred to as the gray matter. In contrast, the layer beneath the cortex is mainly composed of large myelinated axons, which are white and often referred to as the white matter. Humans’ cerebral cortex is deeply convoluted. The convolutions are increasing…
Read MoreDorsal, Ventral and Intermediate Prefrontal Cortex – Scientific Facts
Brain hemispheres sliced into upper, middle and lower thirds result in the following: Upper / dorsal prefrontal cortex, primarily processing “where”, is also associated with so called “cold cognition”, perceptions, executive memories and plans. Lower or ventral prefrontal cortex, processing “what”, is mainly made up by orbital cortex and ventromedial PFC, and Middle or intermediate…
Read MoreThe Neurology of Movement – Unilateral vs Bilateral (II)
The Neurology of Movement (continued) Cerebellum – integrates (and simplifies) the complex data generated from all of our body systems and cognition. Important: it is involved in balance of the body. The cerebellum performs several tasks in movement, such as: Coordinates complex movements ispilaterally (occurring on the same side of the body); Is in direct…
Read MoreNeurology of Unilateral Vs Bilateral Training
A few essential ideas to take home are the following: Two things your brain needs to stay alive: Fuel (glucose, oxygen); Activation; What exercise actually does to the human body? Let’s have a look at the ramification of exercise choice. Bad fuelling means bad brain – bad brain can lead to bad movement & bad…
