Stressful life experiences may be a cause of memory loss as a person ages. Glucocorticoids that are released during stress damage neurons that are located in the hippocampal region of the brain. Therefore, the more stressful situations that someone encounters, the more susceptible they are to memory loss later on. The CA1 neurons found in the hippocampus are destroyed due to glucocorticoids decreasing the release of glucose and the reuptake of glutamate. This high level of extracellular glutamate allow calcium to enter NMDA receptors which in return kills neurons. Stressful life experiences can also cause repression of memories where a person moves an unbearable memory to the unconscious mind. This directly relates to traumatic events in one's past such as kidnappings, being prisoners of war or sexual abuse as a child.
What is the cause of neuron loss due to stress?
high level of extracellular glutamate allow calcium to enter NMDA receptors

The Sanskrit grammatical tradition, Vyakarana, one of the six Vedangas, began in the late Vedic period and culminated in the Astadhyayi of Panini, which consists of 3990 sutras (ca. fifth century BCE). About a century after Panini (around 400 BCE), Katyayana composed Vartikas on the Panini sutras. Patanjali, who lived three centuries after Panini, wrote the Mahabhasya, the "Great Commentary" on the Astadhyayi and Vartikas. Because of these three ancient Vyakaranins (grammarians), this grammar is called Trimuni Vyakarana. To understand the meaning of the sutras, Jayaditya and Vamana wrote a commentary, the Kasika, in 600 CE. Paninian grammar is based on 14 Shiva sutras (aphorisms), where the whole matrika (alphabet) is abbreviated. This abbreviation is called the Pratyahara.
What is the abbreviated alphabet called?
Pratyahara

Hanover was founded in medieval times on the east bank of the River Leine. Its original name Honovere may mean "high (river)bank", though this is debated (cf. das Hohe Ufer). Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century due to its position at a natural crossroads. As overland travel was relatively difficult, its position on the upper navigable reaches of the river helped it to grow by increasing trade. It was connected to the Hanseatic League city of Bremen by the Leine, and was situated near the southern edge of the wide North German Plain and north-west of the Harz mountains, so that east-west traffic such as mule trains passed through it. Hanover was thus a gateway to the Rhine, Ruhr and Saar river valleys, their industrial areas which grew up to the southwest and the plains regions to the east and north, for overland traffic skirting the Harz between the Low Countries and Saxony or Thuringia.
Which city was Hanover connected to by the Leine?
Hanseatic League city of Bremen
