Today, a mishmash of facts about the brain I find fascinating-
1.The cells that form the outer layer of the embryo eventually fold inward and become the very beginning of the spinal cord. Clusters of these cells gather at one end of the spinal cord to become the skull encased brain.
2. The experiences we have in life cause neural firing. The more neurons (nerve cells) firing together (from repeated experiences of all sorts) the stronger the pathway. As neurons fire together, the genes in the nuclei become activated and produce proteins. Proteins allow synaptic linkages to be constructed or strengthned. Remember-neurons are connected to each other by synapses.
3. Experience also stimulates the production of myelin, a fatty sheath around the axon of the neuron. This speeds up firing and synaptic connection.
4. Experience also stimulates neural stem cells to differentiate into new neurons.
I often write about mindfulness and tuning into the inner body and its sensations. These experiences, if done consistently, can literally strengthen your brain functioning and change the neural pathways. Well worth the effort!
