Why does it happen?
- According to neuroscientist and study author Joe Z Tsien, when we are young, our brain is able to strengthen certain connections and weaken certain others to make new memories. "It is that critical weakening that appears hampered in the older brain, " he said.
- Among the changes that occur in the body when children hit puberty, there is a slightly reduced communication time between neurons. "If you don't get rid of the noise or less useful information, it is a problem, " said Tsien. While each neuron averages 3, 000 synapses, their continuous exposure to large quantities of information and experiences demands that the brain erase some of the old information to make room for new. This is probably why we lose the ability to speak a foreign language perfectly after the onset of sexual maturity.
- Scent acts as a powerful memory trigger. The olfactory nerve is located closely to the amygdala — an area of the brain associated with emotional memory — and the hippocampus.
- The hippocampus, a horseshoe-shaped area of the brain, plays an important role in organising and storing information from short-term memory into long-term ones.
