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…

Neurology 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…
