That the brain does so must be either from genes( mostly so) and to a certain extent on environment and upbringing,
How the mind is predisposed to a particular thing is explained as ‘vaasanas’ or predispositions determined /ingrained prior to birth which reinforces the belief in rebirth.The same point of view is applicable to perception as well.
Got a lot of friends? Thank your amygdala! A new study may shed light on how this brain structure, often associated with fear, may regulate our social lives as well.
The study, first published in Nature Neuroscience and also reported in the AP, looked at the size and complexity of people’s social networks by measuring both the number of friends a person had and the number of networks those friends belonged to. They found that large network size and high network complexity were both linked with a larger amygdala, a brain area that the study authors say may have “evolved, in part, under the pressures of increasingly complex social life.” They write,
Humans are inherently social animals. We play, work, eat and fight with one another. A larger amygdala might enable us to more effectively identify, learn about and recognize socioemotional cues […], allowing us to develop complex strategies to cooperate and compete.
Social life is fucking difficult, as another recent study can attest. Quail who were “subjected to social stress” not only had higher stress hormone levels, they also seemed to pass the stress on to their offspring, who were smaller, hatched later, and behaved more cautiously. According to EurekAlert, they also “tend to move about more, which can be interpreted as increased attempts to escape from threats or to seek more social contact.” So, stressed mama quails may give birth to chicks who crave more friends.
